android - 如何在android中关闭AlertDialog

Question

我创建了包含 4 个按钮的 AlertDialog

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() 方法之后关闭它，我该怎么做？提前致谢。

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

所以而不是AlertDialog.Builder optionDialog使用AlertDialog实例。

像，

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

现在，只需打电话 optionDialog.dismiss();

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

我认为有一个更简单的解决方案：只需使用DialogInterface传递给onClick方法的参数即可。

AlertDialog.Builder db = new AlertDialog.Builder(context);
        db.setNegativeButton("cancel", new DialogInterface.OnClickListener(){
            @Override
            public void onClick(DialogInterface d, int arg1) {
                db.cancel();
                //here db.cancel will dismiss the builder

            };  
        });

例如，参见http://www.mkyong.com/android/android-alert-dialog-example。

试试这个：

   AlertDialog.Builder builder = new AlertDialog.Builder(this);
   AlertDialog OptionDialog = builder.create();
  background.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            SetBackground();
       OptionDialog .dismiss();
        }
    });

关闭或取消 AlertDialog.Builder

dialog.setNegativeButton("إلغاء", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialogInterface, int i) {
                        dialogInterface.dismiss();
                    }
                });

你在对话框界面上调用dismiss()

这是我关闭警报对话框的方法

lv_three.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
            @Override
            public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
                GetTalebeDataUser clickedObj = (GetTalebeDataUser) parent.getItemAtPosition(position);
                alertDialog.setTitle(clickedObj.getAd());
                alertDialog.setMessage("Öğrenci Bilgileri Güncelle?");
                alertDialog.setIcon(R.drawable.ic_info);
                // Setting Positive "Yes" Button
                alertDialog.setPositiveButton("Tamam", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        // User pressed YES button. Write Logic Here
                    }
                });
                alertDialog.setNegativeButton("İptal", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialogInterface, int i) {
                        //alertDialog.
                        alertDialog.setCancelable(true); // HERE

                    }
                });
                alertDialog.show();
                return true;
            }
        });

有两种方法可以关闭警报对话框。

选项1：

AlertDialog#create().dismiss();

选项 2：

The DialogInterface#dismiss();

开箱即用，DialogInterface#dismiss();当您为按钮定义事件侦听器时，框架会调用：

AlertDialog#setNegativeButton();
AlertDialog#setPositiveButton();
AlertDialog#setNeutralButton();

用于警报对话框。

只需将视图设置为 null 即可简单地关闭 AlertDialog。
