I\'m new in the android develop world. I created simple application and created a simple GUI with one button. If the user presses this button, I want to change the screen

Answer 1

You can do something like this:

import android.view.View;

/** Called when the activity is first created. */
public class YourActivity extends Activity implements View.OnClickListener {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button button = (Button) findViewById(R.id.your_button_id);
        button.setOnClickListener(this);
    }

    public void onClick(View v) {
        Intent intent = new Intent(your_present_activity.this, target_activity.class);
        startActivity(intent);
    }
}
