问题描述

我创建了包含 4 个按钮的 AlertDialog

I created AlertDialog that contains 4 buttons

OptionDialog = new AlertDialog.Builder(this);
        OptionDialog.setTitle("Options");
        LayoutInflater li = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View v = li.inflate(R.layout.options, null, false);
        background = (Button) v.findViewById(R.id.bkgSpinnerLabel);
        SoundVib = (Button) v.findViewById(R.id.SoundVibSpinnerLabel);

        OptionDialog.setView(v);
        OptionDialog.setCancelable(true);
        OptionDialog.setNeutralButton("Ok",
                new DialogInterface.OnClickListener() {

                    public void onClick(DialogInterface arg0, int arg1) {
                    }
                });
        background.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                SetBackground();
             // here I want to dismiss it after SetBackground() method
            }
        });


        SoundVib.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                Intent soundVibIntent = new Intent(SebhaActivity.this, EditPreferences.class);
                startActivity(soundVibIntent);
            }
        });

        OptionDialog.show();

我想在 SetBackground() 方法后关闭它，我该怎么做?提前致谢.

I want to dismiss it after SetBackground() method, how can I do this?thanks in advance.

推荐答案

实际上 AlertDialog.Builder 类中没有任何 cancel() 或 dismiss() 方法.

Actually there is no any cancel() or dismiss() method from AlertDialog.Builder Class.

所以代替 AlertDialog.Builder optionDialog 使用 AlertDialog 实例.

So Instead of AlertDialog.Builder optionDialog use AlertDialog instance.

喜欢，

AlertDialog optionDialog = new AlertDialog.Builder(this).create();

现在，只需调用 optionDialog.dismiss();

background.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
        SetBackground();
        // here I want to dismiss it after SetBackground() method
        optionDialog.dismiss();
    }
});
