Android AlertDialog关闭方法不起作用

Question

我创建了一个AlertDialog，但是无法关闭它...我可以看到它并按下按钮，但是当我按下“正按钮”时，程序将执行一些任务，然后关闭（关闭）对话框。 所有任务都已完成，没有关闭对话框，它只是闪烁一次（它可能先关闭然后重新打开，我不知道）。

AlertDialog.Builder builder = new AlertDialog.Builder(myContext);
        builder.setTitle("Congratulations, you won!");
        builder.setMessage("Time: x seconds\nScore: xxxx\nHigh score: yyyy");
        builder.setPositiveButton("Play again!",
                new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        // Doing stuff!
                        circle1Paint = yellowPaint;
                        circle2Paint = yellowPaint;
                        circle3Paint = yellowPaint;
                        playing = true;


                        // Trying to close it after doing "the stuff"
                        dialog.dismiss();
                    }
                });
        builder.setNegativeButton("Exit",
                new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        System.exit(0);
                    }
                });
        builder.create.show();

将dilog.dissmiss（）放入退出按钮，然后完成（）;

builder.setNegativeButton("Exit",
            new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                   dialog.dismiss(); 
                  finish();
                }
            });

试试这个代码：

AlertDialog.Builder builder = new AlertDialog.Builder(myContext);
    builder.setTitle("Congratulations, you won!");
    builder.setMessage("Time: x seconds\nScore: xxxx\nHigh score: yyyy");

    builder.setNegativeButton("Exit",
            new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    System.exit(0);
                }
            });
    AlertDialog myDialog = builder.create();
    builder.setPositiveButton("Play again!",
            new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    // Doing stuff!
                    circle1Paint = yellowPaint;
                    circle2Paint = yellowPaint;
                    circle3Paint = yellowPaint;
                    playing = true;


                    // Trying to close it after doing "the stuff"
                    myDialog.dismiss();
                }
            });
    myDialog.show();
