如何解雇AlertDialog Android中 [英] How to dismiss AlertDialog in android

问题描述

我创建AlertDialog包含4个按钮

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();

我要的setBackground（）方法后，将其关闭，我该怎么办呢？ 在此先感谢。

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

推荐答案

其实没有任何取消（）或辞退（）从AlertDialog.Builder类的方法。

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

所以不是 AlertDialog.Builder OptionDialog 使用 AlertDialog 实例。

像，

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

现在，只需拨打 OptionDialog.dismiss（）;

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