Dialog dialog = new Dialog(context)
dialog.setCanceledOnTouchOutside(true); 
//use this to dismiss the dialog on outside click of dialog

dialog.setCanceledOnTouchOutside(false);
//use this for not to dismiss the dialog on outside click of dialog.

dialog.setCancelable(false);
//used to prevent the dismiss of dialog on backpress of that activity

dialog.setCancelable(true);
//used to dismiss the dialog on onbackpressed of that activity

对我来说有用的是创建DialogFragment并将其设置为不可取消:

dialog.setCancelable(false);

Dialog dialog = new Dialog(context)
dialog.setCanceledOnTouchOutside(true); 
//use this to dismiss the dialog on outside click of dialog

dialog.setCanceledOnTouchOutside(false);
//use this for not to dismiss the dialog on outside click of dialog.

//used to prevent the dismiss of dialog on backpress of that activity

dialog.setCancelable(true);
//used to dismiss the dialog on onbackpressed of that activity

在jetpack组合中，使用遣散onclickoutside = false属性来防止关闭。

    AlertDialog(
        title = {
            Text("Title")
        },
        text = {
            Text(text = name)
        },
        onDismissRequest = onDismiss,
        confirmButton = {
            TextButton(onClick = onDismiss ) {
                Text("Yes")
            }
        },
        dismissButton = {
            TextButton(onClick = onDismiss ) {
                Text("Cancel")
            }
        },
        properties = DialogProperties(
            dismissOnClickOutside = false
        )
    )

}

我在onCreate()中使用这个，似乎可以在任何版本的Android上工作;在5.0和4.4上测试。x，不能在姜饼上测试，三星设备(Note 1运行GB)默认是这样的:

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)
    {
        setFinishOnTouchOutside(false);
    }
    else
    {
        getWindow().clearFlags(LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH);
    }

    super.onCreate(savedInstanceState);

警告对话框已弃用，因此使用对话框对话框=新对话框(此);

防止外界接触

dialog.setCanceledOnTouchOutside(false);
