Problem inflating custom view for AlertDialog in DialogFragment

Question

I'm trying to create a DialogFragment using a custom view in an AlertDialog. This view must be inflated from xml. In my DialogFragment class I have:

@Override public Dialog onCreateDialog(Bundle savedInstanceState) {     return new AlertDialog.Builder(getActivity())         .setTitle("Title")         .setView(getActivity().getLayoutInflater().inflate(R.layout.dialog, null))         .setPositiveButton(android.R.string.ok, this)         .setNegativeButton(android.R.string.cancel, null)         .create(); } 

I have tried other inflation methods for .setView() such as:

.setView(getActivity().getLayoutInflater().inflate(R.layout.dialog, (ViewGroup) getView(), false)) 

and

.setView(getActivity().getLayoutInflater().inflate(R.layout.dialog, (ViewGroup) getTargetFragment().getView(), false)) 

After setting the target fragment in the fragment that is showing this dialog.

All of these attempts to inflate my custom view result in the following exception:

E/AndroidRuntime(32352): android.util.AndroidRuntimeException: requestFeature() must be called before adding content E/AndroidRuntime(32352):        at com.android.internal.policy.impl.PhoneWindow.requestFeature(PhoneWindow.java:214) E/AndroidRuntime(32352):        at com.android.internal.app.AlertController.installContent(AlertController.java:248) E/AndroidRuntime(32352):        at android.app.AlertDialog.onCreate(AlertDialog.java:314) E/AndroidRuntime(32352):        at android.app.Dialog.dispatchOnCreate(Dialog.java:335) E/AndroidRuntime(32352):        at android.app.Dialog.show(Dialog.java:248) E/AndroidRuntime(32352):        at android.support.v4.app.DialogFragment.onStart(DialogFragment.java:339) E/AndroidRuntime(32352):        at android.support.v4.app.Fragment.performStart(Fragment.java:1288) E/AndroidRuntime(32352):        at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:873) E/AndroidRuntime(32352):        at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:1041) E/AndroidRuntime(32352):        at android.support.v4.app.BackStackRecord.run(BackStackRecord.java:625) E/AndroidRuntime(32352):        at android.support.v4.app.FragmentManagerImpl.execPendingActions(FragmentManager.java:1360) E/AndroidRuntime(32352):        at android.support.v4.app.FragmentManagerImpl$1.run(FragmentManager.java:411) E/AndroidRuntime(32352):        at android.os.Handler.handleCallback(Handler.java:587) E/AndroidRuntime(32352):        at android.os.Handler.dispatchMessage(Handler.java:92) E/AndroidRuntime(32352):        at android.os.Looper.loop(Looper.java:132) E/AndroidRuntime(32352):        at android.app.ActivityThread.main(ActivityThread.java:4028) E/AndroidRuntime(32352):        at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime(32352):        at java.lang.reflect.Method.invoke(Method.java:491) E/AndroidRuntime(32352):        at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:844) E/AndroidRuntime(32352):        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:602) E/AndroidRuntime(32352):        at dalvik.system.NativeStart.main(Native Method) 

While if I try to use the DialogFragment's getLayoutInflator(Bundle) like this:

.setView(getLayoutInflater(savedInstanceState).inflate(R.layout.dialog, null)) 

I get a StackOverflowError.

Does anyone know how to inflate a custom view for an AlertDialog in a DialogFragment?

Answer 1

The first error line gives me the hint that this is related to how you are creating your dialog - not the dialog itself.

Are you creating the dialog automatically (which could mean this gets called before the views are all set up) or in response to a button click? I initially had problems with fragments due to instantiation order.

I used the same code to set the view as you have, and my result works. I cut out the other setup to make this look cleaner, but it works with or without it.

@Override public Dialog onCreateDialog(Bundle savedInstanceState) {     AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());      View view = getActivity().getLayoutInflater().inflate(R.layout.dialog_layout, null);     builder.setView(view);      return builder.create(); }
