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,对话框将被关闭.我该怎么做?
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); 如果您触摸对话框外部,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.
类似的东西,
Dialog dialog = new Dialog(context) dialog.setCanceledOnTouchOutside(true);或者如果你的 Dialog 在非模型中,
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() 并检查操作类型.如果操作类型是'MotionEvent.ACTION_OUTSIDE' 表示用户在对话区域外进行交互.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; }有关详细信息,请查看 How关闭基于接触点的自定义对话框? 和如何关闭非模态对话框,在对话区域外触摸时
