Android Custom Button Example

Android provides default UI Button for button view.But sometimes we need better UI for application and new colorful button rather than default.so we need to create nice UI for button which looks awesome with application design.

 First you add button in your xml layout file.Then create xml in drawable folder for button background.

in xml drawable file add selector for button.

then add item tag for button state.which has different state like state_pressed,state_focused,state_enabled.

So here we used only state_pressed and check its true or false,then we add other property for both state

now  create two <item ></item> tag and put condition state_pressed or not.

After we can set corner radius for button and when we set radius its looks like rounded box.

Now we have <solid> tag for button inner color.so you can set color for both state.

Using <padding> tab you can put inner spacing.and its considering space from corner of button,

And the last tag is <stroke> which is used for rounded colorful border.and you can set thickness of border using width and its have color also for colorful border.

Now just set your button background in xml layout flie.

 android:background="@drawable/btn"
 
So using below code you can create custom and if you want to set other color select your hex string and past in android:color in solid tag.

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_pressed="true"><shape android:shape="rectangle">
            <corners android:radius="10dp" />

            <solid android:color="#0c76ab" />

            <padding android:bottom="10.0dip" android:left="10.0dip" android:right="10.0dip" android:top="10.0dip" />

            <stroke android:width="1.5dip" android:color="#222" />
        </shape></item>
    <item android:state_pressed="false"><shape android:shape="rectangle">
            <corners android:radius="10dp" />

            <solid android:color="#d9d9d9" />

            <padding android:bottom="10.0dip" android:left="10.0dip" android:right="10.0dip" android:top="10.0dip" />

            <stroke android:width="1.5dip" android:color="#222" />
        </shape></item>

</selector>

Android View Pager With Remote Images

         

Android View Pager is Layout Manager you can change it Left and Right.And you can see more than one view using swapping.And its works like image galllery.

First insert ViewPager in your xml  layout file ::

 <android.support.v4.view.ViewPager
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/pager"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_above="@+id/button1"
        android:layout_margin="5dp" />

Now View Pager is working as a horizontal ScrollView.And View Pager have rows for each view.So create row for each view in layout,

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="1dip" >

    <ImageView
        android:id="@+id/image"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:adjustViewBounds="true"
        android:contentDescription="desc" />

    <ProgressBar
        android:id="@+id/loading"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:visibility="gone" />

</FrameLayout>

Now at Java Coding side create object of ViewPager and give References from XML file,And ViewPager set  Adapter for pager.

ViewPager pager = (ViewPager) findViewById(R.id.pager);
pager.setAdapter(new ImagePagerAdapter(imageUrls));


Now extends PagerAdapter Class For  View Pager's Adapter.Now we have override method which is inflate each row in pager and create view for Pager


        @Override
        public Object instantiateItem(View view, int position) {
            final View imageLayout = inflater.inflate(
                    R.layout.item_pager_image, null);
            final ImageView imageView = (ImageView) imageLayout
                    .findViewById(R.id.image);
            final ProgressBar spinner = (ProgressBar) imageLayout
                    .findViewById(R.id.loading);
}





instantiateItem Method is working as like as getView method in listView.

Now View Pager has PageChangeListener to listen page changing.You get current page using getCurrentPage from DetailOnPageChangeListener class.

pager.setOnPageChangeListener(new DetailOnPageChangeListener());

    public class DetailOnPageChangeListener extends
            ViewPager.SimpleOnPageChangeListener {

        private int currentPage;

        @Override
        public void onPageSelected(int position) {

            currentPage = position;
        }

        public int getCurrentPage() {
            return currentPage;
        }
    }

you get Current page using button click.So when you click on button get current page From Pager Listener. also and you can download below full source code:

Android Multiple Select ListView

Android Multiple Choice ListView Using Custom Adapter.This listview you can use when you send sms to more than one friend or any notification to your friends.


So using Custom Adapeter we have to create row.xml layout which has checkbox.

row.xml

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="50dp"
    android:background="@android:color/white" >

    <TextView
        android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_centerVertical="true"
        android:layout_margin="5dp"
        android:layout_toLeftOf="@+id/checkbox"
        android:text="title"
        android:textColor="@android:color/black"
        android:textSize="20dp"
        android:textStyle="bold" >
    </TextView>

    <CheckBox
        android:id="@+id/checkbox"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_centerVertical="true"
        android:layout_marginRight="10dip"
        android:background="@drawable/chk"
        android:button="@null"
        android:focusable="false"
        android:focusableInTouchMode="false" >
    </CheckBox>
</RelativeLayout>

 Now Using Adapter we can bind data to ListView.But we need to learn easy way to bind data with custom ListView and also hadle CheckBox Listener For Each Row.

So here i have RSS Feed to get data from web and then i add it in List<NameBean>.NameBean is bean class which contains value of Rss Feed Element and we have to maintain one boolean for checkbox state either checked or not.And generate Getters And Setters.

NameBean.java

public class NameBean {

private String name;
private boolean selected;

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public boolean isSelected() {
return selected;
}

public void setSelected(boolean selected) {
this.selected = selected;
}

}

Now when you get data through XML Parsing you have to create Object of NameBean and you can set data and add Object to List.


for (int temp = 0; temp < nList.getLength(); temp++) {

Node nNode = nList.item(temp);

                  if (nNode.getNodeType() == Node.ELEMENT_NODE) {

   Element eElement = (Element) nNode;

    NameBean objItem = new NameBean();

   objItem.setName(getTagValue("name", eElement));
                 
   list.add(objItem);

}
}



Now list  is fill up with NameBean Objects.And you can retrive data in Adapter so when you set ListView you just retrieve data in getView(...) method of Adapter.

In getView(...) method put checkBox listener to listen checkbox is check or not, if its checked then set boolean true for that object of NameBean And if its not checked then setSelected false to Namebean object.

So when you start this example in listview and its get data from webservice and bind data to listview using NameAdapter Class.



NameAdapter.java


import java.util.List;

import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.TextView;

public class NamesAdapter extends ArrayAdapter<NameBean> {

private List<NameBean> list;
private LayoutInflater inflator;

public NamesAdapter(Activity context, List<NameBean> list) {
super(context, R.layout.row, list);
this.list = list;
inflator = context.getLayoutInflater();
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {

ViewHolder holder = null;
if (convertView == null) {
convertView = inflator.inflate(R.layout.row, null);
holder = new ViewHolder();
holder.title = (TextView) convertView.findViewById(R.id.title);
holder.chk = (CheckBox) convertView.findViewById(R.id.checkbox);
holder.chk
.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

@Override
public void onCheckedChanged(CompoundButton view,
boolean isChecked) {
int getPosition = (Integer) view.getTag();
list.get(getPosition).setSelected(view.isChecked());

}
});
convertView.setTag(holder);
convertView.setTag(R.id.title, holder.title);
convertView.setTag(R.id.checkbox, holder.chk);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.chk.setTag(position);

holder.title.setText(list.get(position).getName());
holder.chk.setChecked(list.get(position).isSelected());

return convertView;
}

static class ViewHolder {
protected TextView title;
protected CheckBox chk;
}
}


When your listView is bind with data you can see checkbox in row with name and now you can get Selected name using NameBean Object and you can retrieve it from list.


                // Retrive Data from list Using for-each loop
                StringBuffer sb = new StringBuffer();
for (NameBean bean : items) {

if (bean.isSelected()) {
sb.append(bean.getName());
sb.append(",");
}
}



Now you get All Selected name from ListView.So its so easy to write Multiple Choice ListView in Android.

Android Populate Spinner From Sqlite Database

Android Spinner is DropDown Choice List in Android.You can pick up one item and make your choice from list.

When you get Data from database and display in Spinner, So first you have to create database to get data from database and save it in Dynamic Array.

So first Create DataBaseHelper.java that create database and add data in database.


package com.samir.spinner;

import java.util.HashSet;
import java.util.Set;

import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;

public class DatabaseHelper extends SQLiteOpenHelper {
private static final int DB_VERSION = 1;
private static final String DB_NAME = "mydb";
private static final String TABLE_NAME = "mytable";
private static final String _id = "_id";
private static final String name = "name";

public DatabaseHelper(Context context) {
super(context, DB_NAME, null, DB_VERSION);
}

@Override
public void onCreate(SQLiteDatabase db) {
String createTableQuery = "create table " + TABLE_NAME + "(" + _id+ "     INTEGER PRIMARY KEY," + name + " TEXT)";
db.execSQL(createTableQuery);
}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion)  
        {
db.execSQL("drop table if exists " + TABLE_NAME);
onCreate(db);
}

public void insertData(String label) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(name, label);
db.insert(TABLE_NAME, null, values);
db.close();
}

public Set<String> getAllData() {
Set<String> set = new HashSet<String>();
String selectQuery = "select * from " + TABLE_NAME;
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.rawQuery(selectQuery, null);
if (cursor.moveToFirst()) {
do {
set.add(cursor.getString(1));
} while (cursor.moveToNext());
}
cursor.close();
db.close();
return set;
}
}

Now you can see Oncreate Method is Create Database and using query you can create database.Database have two column one in _id which is primary key and second is name which we  want to save in database.

Then Using  ContentValue you can insert Data in database see method insertData(String lable) in above class.

Now, To get All data from database you just fire query and its return Cursor.Then put data in dynamic array from cursor.See method  getAllData().

Here i used Set<String> as dynamic array Because Set doesnot allow duplicates.And Spinner only show unique name.

Once you get Set then you can easily convert it in List<String>.Then you can easily append data to spinner using ArrayAdapter.


       Set<String> set = db.getAllData();
       //Convert set into list
  List<String> list = new ArrayList<String>(set);
  //Sort Data Alphabetical order
  Collections.sort(list, new Comparator<String>() {
@Override
public int compare(String lhs, String rhs) {
return lhs.compareTo(rhs);
}
  });
  adapter = new ArrayAdapter<String>(MainActivity.this,
android.R.layout.simple_spinner_item, list);
  adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
  spinner.setAdapter(adapter);


Now spinner have listener to listen selected item . 

spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View v, int position,long id) {
     String name = parent.getItemAtPosition(position).toString();
showToast("You Selected Item :: " + name);
       }
@Override
public void onNothingSelected(AdapterView<?> arg0) {
}
    });

Android Sectioned Listview with Search Bar

   
         




Here i put  Sectioned Listview in android.And I add some feature like AsyncTask,Xml Parsing,Bind data in listview with section,Sorting Data to A to Z,Searching in Listview using search bar And onclick in listview get row name.
 

Features ::

1. How to Work with AsyncTask in android?  

       - See this Example

2.Android XML parser using DOM parser.

      - Get Data From This File 

      - See this Example

3.Bind data in Listview using Custom Adapter.

   -Using ArrayAdapter<ClassName> we can bind data in listview.

      

      Android custom adapter have a row layout you can add your view in this layout and then you can add this view(row) in listview row.Using Inflater we can add row in listview.in getView() method is bind one by one data in Listview.Use ViewHolder to inflate row is better.See this Video For Fast UI and Efficient .

4.Sort data in Alphabetical order using Comparable.

 

 -In java to sort any Collection here List<Item>,we have to way one is Comparator<Item> and other is  Comparable<Item>.Between angle brackets there is your bean class name.

When we implements this interfacee that implements one method compareTo(Items another).this method's 

parameter have another object and you can compare any field with another object.

if you have List<Items>  objListItems = new ArrayList<Items>(); 

then you can sort it , Collections.sort(objListItems);

5.Sectioned Listview.

- In section view there are first letter of list items and we can see separated list items using section .See above Screen Shots.

when we get data from web then catch first letter from list items and add it in dynamic array .Then bind it in listview using in different view .

In my code put some logic for sectioned Listview and how to bind sectioned data in Listview.

6.How to Work with Search Bar in ListView?

-In search bar we have one Edittext and You can type any Letter then Listview filter data and so only filtered data.Suppose i have name listview.And i type `s`,then listview display only items which startwith `s`

you can do it using TextWatcher  interface in android EditText.

myEditText.addTextChangedListener(this);

Now implements  TextWatcher to your Activity and implemented three methods.Now, In afterTextChanged method we can filter ListView and then refresh ListView.Using adapter.notifyDataSetChanged(); you can refresh ListView.
