I have implemented a custom dialog for my application. I want to implement that when the user clicks outside the dialog, the dialog will be dismissed. What do I have to do for this?

推荐答案

您可以使用 dialog.setCanceledOnTouchOutside(true); 如果您触摸对话框之外，它将关闭对话框.

You can use dialog.setCanceledOnTouchOutside(true); which will close the dialog if you touch outside of the dialog.

类似的，

  Dialog dialog = new Dialog(context)
  dialog.setCanceledOnTouchOutside(true);

或者，如果您的 Dialog 在非模型中，那么，

Or if your Dialog in non-model then,

1 - 为对话框的窗口属性设置标志-FLAG_NOT_TOUCH_MODAL

1 - Set the flag-FLAG_NOT_TOUCH_MODAL for your dialog's window attribute

Window window = this.getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);

2 - 向窗口属性添加另一个标志，FLAG_WATCH_OUTSIDE_TOUCH - 这个标志用于对话框在其可见区域之外接收触摸事件.

2 - Add another flag to windows properties,, FLAG_WATCH_OUTSIDE_TOUCH - this one is for dialog to receive touch event outside its visible region.

3 - 覆盖对话框的 onTouchEvent() 并检查动作类型.如果动作类型是'MotionEvent.ACTION_OUTSIDE' 表示用户在对话区域之外进行交互.因此，在这种情况下，您可以关闭对话或决定要执行的操作.查看普通版?

3 - Override onTouchEvent() of dialog and check for action type. if the action type is 'MotionEvent.ACTION_OUTSIDE' means, user is interacting outside the dialog region. So in this case, you can dimiss your dialog or decide what you wanted to perform. view plainprint?

public boolean onTouchEvent(MotionEvent event)  
{  

       if(event.getAction() == MotionEvent.ACTION_OUTSIDE){  
        System.out.println("TOuch outside the dialog ******************** ");  
               this.dismiss();  
       }  
       return false;  
}
