Android Blog: Simple Adapter Example?

Let’s Code!

This Example is Also used to click any specific row that data display in the Second Activity.

We only need this files to run this sample code successfully.

activity_main.xml -- our main layout. Our trigger to show the ListView

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <ListView
        android:id="@+id/listView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >
    </ListView>

</RelativeLayout>
 

MainActivity.java

public class MainActivity extends Activity {
 ListView listview;

 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);

  String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
    "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X", "Linux", "OS/2" };
    int[] images = new int[] {R.drawable.image1, R.drawable.image2, R.drawable.image3, R.drawable.image4,
    R.drawable.image5, R.drawable.ic_launcher };
  listview = (ListView) findViewById(R.id.listView);

  // use your own layout
  MySimpleArrayAdapter adapter = new MySimpleArrayAdapter(this, R.layout.rowlayout, values, images);
  listview.setAdapter(adapter);
  listview.setOnItemClickListener(new OnItemClickListener() {
   @Override
   public void onItemClick(AdapterView<?> arg0, View view, int id, long position) {      
    Object  ob = (Object) view.getTag();     
    if(ob != null)  {      
     TotalFavouriteInfo history_title = (TotalFavouriteInfo) view.getTag();     
     String title = history_title.getPage_name(); 
     Bitmap image = history_title.getPage_date();
      Toast.makeText(MainActivity.this, "position ==> " +position + title + image , Toast.LENGTH_SHORT).show();
     
     Intent intent = new Intent(MainActivity.this, SecondActivity.class);
     intent.putExtra("position", title);
     intent.putExtra("mage_bit", image);
     startActivity(intent);     
     }        
   }
