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。
