WindowManagerBadTokenException无法添加窗口 [英] WindowManagerBadTokenException unable to add window

问题描述

我在下面有一个错误：

  //TODO tryAgain
private void tryAgain(){
    new AlertDialog.Builder(this)
    .setTitle("Game Over")
    .setMessage("Times Up!")
    .setPositiveButton("Try Again?", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) { 
            dialog.cancel();
            Intent retry = getIntent();
            finish();
            startActivity(retry);
        }
     })
    .setNegativeButton("Back to Menu", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) { 
            dialog.cancel();
            Intent i = new Intent(Stage1_3.this, ShapingColors.class);
            finish();
            startActivity(i);
        }
     })
     .show();   
}   

基本上我要做的是取消对话框，然后重新启动我当前的活动，另一个我想回到菜单活动。我在这里想念的是什么？任何帮助表示赞赏。

Basically what I want to do is cancel the dialog then restart my current activity and the other one I want to go back to menu activity. What am I missing in here? Any help is appreciated.

UPDATE LOGCAT：

推荐答案

当您显示不再存在的上下文的对话框时，可能会发生这种情况。当您调用 show（）对话框时，活动将被销毁。这通常在异步操作之后发生。确保您的活动（您要在其中显示对话框）正在运行。

This can occur when you are showing the dialog for a context that no longer exists. When you are calling show() of dialog the activity is destroyed. This happens generally after async operations. Make sure that your activity(in which you want to show dialog) is running.

完成后不要调用活动只需创建新意图并启动活动。这样做：

Don't call the activity after finishing it just create a new intent and start the activity. Do like this:

private void tryAgain(){
    new AlertDialog.Builder(this)
    .setTitle("Game Over")
    .setMessage("Times Up!")
    .setPositiveButton("Try Again?", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) { 
            dialog.cancel();
            Intent retry = new Intent(this, Stage1_3.class);//I guess Stage1_3 is the current activity
            finish();
            startActivity(retry);
        }
     })
    .setNegativeButton("Back to Menu", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) { 
            dialog.cancel();
            Intent i = new Intent(Stage1_3.this, ShapingColors.class);
            finish();
            startActivity(i);
        }
     })
     .show();   
}
