import android.widget.Button;
public class testprj extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button btn1 = (Button) findViewById(R.id.btn1);

Don't ever put an Exit button on an Android app. Let the OS decide when to kill your Activity. Learn about the Android Activity lifecycle and implement any necessary callbacks.
try this for close app
Activity.finish();
System.exit(0);
i try this
Button btnexit = (Button)findviewbyId(btn_exit);
btnexit.setOnClicklistenr(new onClicklister(){
@override
public void onClick(View v){
finish();
});
this.close_Button = (Button)this.findViewById(R.id.close);
this.close_Button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
finish();
}
});
finish()
- Call this when your activity is done and should be closed. The ActivityResult
is propagated back to whoever launched you via onActivityResult()
.
