DialogFragment : Using AlertDialog with custom layout

android, android-alertdialog, android-fragments

Solution

I'm surprised that nobody answered. This is the solution:

public class PropDialogFragment extends DialogFragment {

    private PropDialogFragment() { /*empty*/ } 

    /** creates a new instance of PropDialogFragment */
    public static PropDialogFragment newInstance() {
        return new PropDialogFragment();
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        //getting proper access to LayoutInflater is the trick. getLayoutInflater is a                   //Function
        LayoutInflater inflater = getActivity().getLayoutInflater();

        View view = inflater.inflate(R.layout.my_dialog, null);
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setView(view);
        builder.setTitle(getActivity().getString(R.string.sysinfo)).setNeutralButton(
                getActivity().getString(R.string.okay), null);
        return builder.create();
    }
}

You can show the dialog using :

private void showDialog() {
    // DialogFragment.show() will take care of adding the fragment
    // in a transaction.  We also want to remove any currently showing
    // dialog, so make our own transaction and take care of that here.
    FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
    Fragment prev = getSupportFragmentManager().findFragmentByTag("dialog");
    if (prev != null) {
        ft.remove(prev);
    }
    ft.addToBackStack(null);

    // Create and show the dialog.
    DialogFragment newFragment = PropDialogFragment.newInstance();
    newFragment.show(ft, "dialog");
}
