requestFeature() must be called before adding content
I know it's over a year old, but calling requestFeature()
never solved my problem. In fact I don't call it at all.
It was an issue with inflating the view I suppose. Despite all my searching, I never found a suitable solution until I played around with the different methods of inflating a view.
AlertDialog.Builder is the easy solution but requires a lot of work if you use the onPrepareDialog()
to update that view.
Another alternative is to leverage AsyncTask for dialogs.
A final solution that I used is below:
public class CustomDialog extends AlertDialog {
private View content;
public CustomDialog(Context context) {
super(context);
LayoutInflater li = LayoutInflater.from(context);
content = li.inflate(R.layout.custom_view, null);
setUpAdditionalStuff(); // do more view cleanup
setView(content);
}
private void setUpAdditionalStuff() {
// ...
}
// Call ((CustomDialog) dialog).prepare() in the onPrepareDialog() method
public void prepare() {
setTitle(R.string.custom_title);
setIcon( getIcon() );
// ...
}
}
* Some Additional notes:
- Don't rely on hiding the title. There is often an empty space despite the title not being set.
- Don't try to build your own View with header footer and middle view. The header, as stated above, may not be entirely hidden despite requesting FEATURE_NO_TITLE.
- Don't heavily style your content view with color attributes or text size. Let the dialog handle that, other wise you risk putting black text on a dark blue dialog because the vendor inverted the colors.
Well, just do what the error message tells you.
Don't call setContentView()
before requestFeature()
.
Note:
As said in comments, for both ActionBarSherlock
and AppCompat
library, it's necessary to call requestFeature()
before super.onCreate()
I was extending a DialogFragment and the above answer didnot work. I had to use getDialog() to achieve remove the title:
getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
