简介
一、设置是否点击dialog外部取消dialog
这个直接设置setCanceledOnTouchOutside方法即可。
二、点击外部自己监听事件
有时候我们不仅仅是需要设置点击外部取消,而是想做一些其他的动作，比如我就遇到过需要把外部点击事件发送给下层Activity的情况。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Make us non-modal, so that others can receive touch events.
getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL, WindowManager.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);
}
三、设置外部透明
设置dialog外部透明。
getWindow().setDimAmount(0F)
