import android.view.Menu;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends Activity {
TextView tv1, tv2, tv3;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv1 = (TextView) findViewById(R.id.textView1);
tv2 = (TextView) findViewById(R.id.textView2);
tv3 = (TextView) findViewById(R.id.textView3);
tv1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), "Static TextView Clicked",
Toast.LENGTH_SHORT).show();
}
});
tv2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), "Java Clicked",
Toast.LENGTH_SHORT).show();
}
});
tv2.setOnLongClickListener(new View.OnLongClickListener() {
public boolean onLongClick(View v) {

Toast.LENGTH_SHORT).show();
return true;
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
Step 4 : Open AndroidManifest.xml and add following code :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.gudivada.hemanthsomaraju"
android:versionCode="1"
