Question

我有一个没有按钮的AlertDialog。点击它时如何关闭对话框？

Answer 1

我能想到的问题是将自己的视图设置为该对话框，然后可以将onClickListener设置为该视图，这样就可以处理click事件。以下是我的代码：

@Override
protected Dialog onCreateDialog(int id, Bundle args) {
    AlertDialog.Builder builder=new Builder(this);
    builder.setTitle("title");

    LayoutInflater inflater=(LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View view=inflater.inflate(R.layout.firstview, null);//inflate your own view
    view.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            YourActivity.this.dismissDialog(dialog_ID);//dismiss the dialog
        }
    });

    builder.setView(view);//set your custom view to your dialog

    return builder.create();
}

Answer 2

这将关闭用户在对话框外触摸的对话框，因此无需按钮：

dialog.setCanceledOnTouchOutside(true);

Answer 3

你必须为它创建自定义对话框。看下面的链接，它会帮助你

您还在特定时间后关闭了对话框。见下面的链接。

Answer 4

如果您希望通过单击对话框并在对话框外部关闭自定义对话框，请使用以下代码：

private void showDialog() {
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        LayoutInflater inflater = (LayoutInflater)getSystemService                                        (Context.LAYOUT_INFLATER_SERVICE);
        View v = inflater.inflate(R.layout.your_custom_dialogLayout, null);
        builder.setView(v);
        builder.setCancelable(true);//Dialog dismissed by click outside
        final AlertDialog dialog = builder.create();
        v.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog.dismiss(); //Dialog dismissed by click on dialogs content
            }
        });
        dialog.show();
   }

不使用按钮关闭AlertDialog
