Place a button inside DialogFragment's title

问题

I show a DialogFragment from another DialogFragment. I need to set title and a button just next to it. I don't want to reimplement the theme and create a custom view inside DialogFragment's content view instead of dialog title (because it's error-prone and time wasting). Is it even possible? I tried many API functions, AlertBuilder, ActionBar, this and that, still didn't found anything that fits my needs.

回答1:

Try something like this:

// Title
final int titleId = getResources().getIdentifier("alertTitle","id","android");
TextView title = (TextView) popup.findViewById(titleId);
title.setText("My new title");

// Title's parent layout
ViewGroup viewGroup = (ViewGroup) title.getRootView();

// Button
Button button = new Button(this);
button.setText("A Button");
viewGroup.addView(button);

Note: You may need to adjust the button and title objects' LayoutParams.

An update. This can be achieved by calling setCustomTitle on AlertDialog.Builder class. Available since api level 1, and do not require a bunch of code.

Example:

AlertDialog.Builder(getActivity()).setCustomTitle(getActivity().getLayoutInflater().inflate(R.layout.my_custom_view, viewGroup)).create()
