setVisibility()
应该可以解决您的问题。使用view.setVisibility(view.VISIBLE)
和view.setVisibility(view.GONE)
动态显示和隐藏活动布局中的视图。或者,如果您有多个xml文件,并且希望在同一活动中显示它们,那么只需再次使用适当的id调用setContentView(id)
public class TouchImageViewActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.button1);
TouchImageView img = (TouchImageView) findViewById(R.id.snoop);
img.setImageResource(R.drawable.keutamaandua);
img.setMaxZoom(4f);
