Android 关闭自定义对话框

我正在尝试让自定义对话框在按下按钮时关闭

        //set up dialog
        Dialog dialog = new Dialog(BrowseActivity.this);
        dialog.setContentView(R.layout.about);
        dialog.setTitle("This is my custom dialog box");
        dialog.setCancelable(true);
        //there are a lot of settings, for dialog, check them all out!

        //set up text
        TextView text = (TextView) dialog.findViewById(R.id.TextView01);
        text.setText(R.string.app_help_message);

        //set up image view
        ImageView img = (ImageView) dialog.findViewById(R.id.ImageView01);
        img.setImageResource(R.drawable.icon);

      //set up button
        Button button = (Button) dialog.findViewById(R.id.Button01);
        button.setOnClickListener(new View.OnClickListener() {
        @Override
            public void onClick(View v) {
            Dialog.dismiss();

            }
        });

        //now that the dialog is set up, it's time to show it    
        dialog.show();

       return true;

dialog.dismiss 对我不起作用。我只是想使用此自定义对话框作为帮助屏幕，并希望按下按钮将其关闭。

我对 Android 开发很陌生，但已经尝试了很多个小时

感谢您的任何建议

final Dialog dialog = new Dialog(BrowseActivity.this);

您需要小写对话框。

public void onClick(View v) {
   dialog.dismiss();
}

Also AlertDialog.Builder可能是您更好的选择。
