Question

我想问一下，我是否可以在对话框的标题中点击一个图标。我使用以下行在对话框的左侧设置标题“New Contact”，在右侧设置一个图标。那么，这个图标（x5）可以通过某种方式变为可点击吗？我希望它像关闭按钮一样运作。

dialog.requestWindowFeature（Window.FEATURE_RIGHT_ICON）;

     dialog.setTitle("New Contact                 ");
     dialog.setContentView(R.layout.pop_up_new_contact);//loads the layout we have already create pop_up_new_contact.xml
     dialog.setFeatureDrawableResource(Window.FEATURE_RIGHT_ICON, R.drawable.x5);//adds an icon in the left of the Title.
     dialog.setCancelable(true);

我找到了解决方案！这就是我所做的，以防有人需要它。

@Override
protected Dialog onCreateDialog(int id)  {//creates the dialog

final Dialog dialog = new Dialog(this);

dialog.requestWindowFeature( Window.FEATURE_CUSTOM_TITLE );//adds in the dialog box a frame for the custom title

@Override
protected Dialog onCreateDialog(int id)  {//creates the dialog
    final Dialog dialog = new Dialog(this);

    dialog.requestWindowFeature( Window.FEATURE_CUSTOM_TITLE );//adds in the dialog box a frame for the custom title

    //dialog.setTitle("New Contact");//sets the title of the dialog box

    dialog.setContentView(R.layout.pop_up_new_contact);//loads the layout we have already create pop_up_new_contact.xml
    dialog.getWindow().setFeatureInt( Window.FEATURE_CUSTOM_TITLE, R.layout.custom_title_dialog_box);//sets our custom title(custom_title_dialog_box.xml) as the current title of the dialog box. The custom_title_dialog_box.xml contains a TextView with id: title_new_contact and an ImageView with id: x1_button.

    dialog.setCancelable(true);//close the dialog box when the back key is pushed.

    ImageView x1_button = (ImageView)dialog.findViewById(R.id.x1_button);

    x1_button.setOnClickListener(new View.OnClickListener(){
        public void onClick(View View3) {
         dialog.dismiss();
        }
    });

    return dialog;
}

也许这不是最好的解决方案，但至少它有效！

最好创建一个自定义对话框。但其糟糕的用户体验设计将其用作关闭按钮，因为Android用户习惯于后退做同样的操作。

Answer 3

我确实发现这并不是你所要求的，但是如果你正在寻找一个前瘾按钮。这将有效。

dialog.setButton(getText(R.string.cancel), new DialogInterface.OnClickListener()
{
   public void onClick(DialogInterface dialog, int whichButton) { }
});
