如何通过点击对话框外的对话框来关闭对话框？ [英] How to dismiss the dialog with click on outside of the dialog?

问题描述

我已经为我的应用程序实现了一个自定义对话框。我想实现，当用户在对话框外单击时，对话框将被忽略。
我需要做什么？

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）; 如果您触摸到对话框外面将关闭该对话框。

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

像

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

或者如果您的对话框非模型，

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Windows属性添加另一个标志， FLAG_WATCH_OUTSIDE_TOUCH - 这是一个对话框，可以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 onTouchEvent（）对话框，并检查动作类型。如果动作类型为
' MotionEvent.ACTION_OUTSIDE '表示用户正在对话区域外进行交互。因此，在这种情况下，您可以调整对话框或决定要执行的操作。
查看plainprint？

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;  
}
