I have a DialogFragment
that is styled to full screen using setStyle(STYLE_NORMAL, R.style.Theme_App)
.
The DialogFragment
shows fine but the up action (the homeAsUp
action on the ActionBar) does not work. I tried implementing onOptionsItemSelected
in the DialogFragment
but it is never called.
Is there a way to get the up action callback in the DialogFragment so I can dismiss it ? For reference, I'm using ActionBarCompat
.
This wasn't possible but there is a workaround for this using aToolbar
. Now you can include Toolbar
as part of your DialogFragment
layout xml
and can set its design/icon according to your needs. You will also need to implement setNavigationOnClickListener
if you want the back button to behave like it does normally. See the sample class below.
package com.package.name;
import android.app.Dialog;
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.v4.app.DialogFragment;
import android.support.v7.widget.Toolbar;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.LinearLayout;
public class MyDialogFragment extends DialogFragment {
private View parentView;
private Toolbar toolbar;
@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
setStyle(DialogFragment.STYLE_NO_FRAME, R.style.Theme_AppCompat_NoActionBar);
return super.onCreateDialog(savedInstanceState);
}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
//The layout xml file contains the toolbar
parentView = inflater.inflate(R.layout.dialogfragment_createpost, container, false);
initView();
initData();
return parentView;
}
private void initView() {
toolbar = (Toolbar) parentView.findViewById(R.id.toolbar);
}
private void initData() {
toolbar.setTitle("Post");
//Set naviagtion icon to back button drawable
toolbar.setNavigationIcon(R.drawable.abc_ic_ab_back_mtrl_am_alpha);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// handle back button naviagtion
dismiss();
}
});
}
}
