对话框样式Activity获得窗口外点击事件

在API11之后添加了setFinishOnTouchOutside()方法，只需要在onCreate()方法中调用：

this.setFinishOnTouchOutside(false);

API11之前

public class MyActivity extends Activity { @Override  protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    // Make us non-modal, so that others can receive touch events.    getWindow().setFlags(LayoutParams.FLAG_NOT_TOUCH_MODAL, LayoutParams.FLAG_NOT_TOUCH_MODAL);    // ...but notify us that it happened.    getWindow().setFlags(LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH, LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH);    // Note that flag changes must happen *before* the content view is set.    setContentView(R.layout.my_dialog_view);  }  @Override  public boolean onTouchEvent(MotionEvent event) {    // If we've received a touch notification that the user has touched    // outside the app, finish the activity.    if (MotionEvent.ACTION_OUTSIDE == event.getAction()) {      finish();      return true;    }    // Delegate everything else to Activity.    return super.onTouchEvent(event);  }}
