How to set layout dynamically in android

Question

Well, Suppose there is an Activity called MainActivity and there are two layouts called layout1 and layout2 both have few

Answer 1

When you are seting layout2, you should also set up OnClickListener to someBtn1 and vice versa, I'd suggest something like this. But as in prevoius answer, in general you should avoid mixing layouts in such manner.

public class MainActivity extends Activity {

    private final View.OnClickListener setLayout1Listener = new View.OnClickListener() {
        @Override
        public void onClick(View view) {
           setContentView(R.layout.layout2);
           ((Button)findViewById(R.id.Btn2Id)).setOnClickListener(setLayout2Listener);
           //do other stuff
        }
    };

    private final View.OnClickListener setLayout2Listener = new View.OnClickListener() {
        @Override
        public void onClick(View view) {
           setContentView(R.layout.layout1);
           ((Button)findViewById(R.id.Btn1Id)).setOnClickListener(setLayout1Listener);
           //do other stuff
        }
    };



    @Override
    public void onCreate(final Bundle savedInstance) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.layout1);
        ((Button)findViewById(R.id.Btn1Id)).setOnClickListener(setLayout1Listener);
        //do other stuff
    }
}
