Static ListView Creation in Android
Step 1 : Select File -> New -> Project -> Android Application Project (or) Android Project. Fill the forms and click "Finish" button. If you have any doubt regarding create a new project
Click Here.
Step 2 : Open res -> layout ->
activity_main.xml (or) main.xml and add following code :
<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" >
<ListView
android:id="@+id/listView1"

import android.support.v4.app.NavUtils;
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
Step 4 : Open AndroidManifest.xml and add following code :

} else if (s.equals("android")) {
imageView.setImageResource(R.drawable.android);
} else if (s.equals("apple")) {
imageView.setImageResource(R.drawable.apple);

imageView.setImageResource(R.drawable.fb);
} else if (s.equals("twitter")) {
imageView.setImageResource(R.drawable.twitter);
}
else {
imageView.setImageResource(R.drawable.google);
}
return rowView;
}
}

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.gudivada.hemanthsomaraju"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="19" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.gudivada.hemanthsomaraju.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
