android - Android关闭自定义对话框

Question

我试图让自定义对话框在按钮按下时关闭

        //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。我只是想将此自定义对话框用作帮助屏幕，并希望按下按钮将其关闭。

我对android dev很陌生，但已经尝试了很多小时

感谢您的任何建议

Answer 1

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

您需要小写对话框。

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

也AlertDialog.Builder可能是您更好的选择。

Answer 2

你可以调用dismiss(); 在对话框上。这对我有用。
