Android how to use Toolbar in ListActivity?

Question

I made a ListActivity:

 public class NoteListActivity extends ListActivity{
 }

and the following methods are no longer available:

    setSupportActionBar(toolbar);
    getSupportActionBar().setHomeButtonEnabled(true);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

But I can use:

    setActionBar(toolbar);
    getActionBar().setHomeButtonEnabled(true);
    getActionBar().setDisplayHomeAsUpEnabled(true);

Note that I used Support library in other activities in the same project. It means I have the correct gradle dependency added.

How do I use ListActivity and android.support.v7.widget.Toolbar ?

Answer 1

You can't do that in ListActivity.

If you want to access getSupportActionBar(), you need to extend your class with AppCompatActivity.

My Suggestion : Don't use ListActivty as you want to use ToolBar. Create an Activity and then only have ListView within that Activity. It'll work just fine.

     @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    AppCompatCallback callback = new AppCompatCallback() {
        @Override
        public void onSupportActionModeStarted(ActionMode actionMode) {
        }

        @Override
        public void onSupportActionModeFinished(ActionMode actionMode) {
        }

        @Nullable
        @Override
        public ActionMode onWindowStartingSupportActionMode(ActionMode.Callback callback) {
            return null;
        }
    };

    AppCompatDelegate delegate = AppCompatDelegate.create(this, callback);

    delegate.onCreate(savedInstanceState);
    delegate.setContentView(R.layout.saved_report_activity);

    Toolbar toolbar= (Toolbar) findViewById(R.id.toolbar);
    delegate.setSupportActionBar(toolbar);
    delegate.getSupportActionBar().setDisplayShowHomeEnabled(true);

    toolbar.setNavigationIcon(R.drawable.abc_ic_ab_back_mtrl_am_alpha);
    toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            NavUtils.navigateUpFromSameTask(SavedReportActivity.this);
        }
    });

Answer 3

AppCompatActivity is the direct child class of FragmentActivity of support v4 .Read this article

http://android-developers.blogspot.it/2015/04/android-support-library-221.html so for your requirement, public class NoteListActivity extends AppCompatActivity {...}

Just change your dependency,Like :

compile "com.android.support:appcompat-v7:22.1.0"

I was able to solve this by adding a support library toolbar style and then adding the style to my list activity in the manifest.

In styles.xml:

     <style name="FullscreenActionBarStyle" parent="Widget.AppCompat.ActionBar">

In Manifest

    <activity android:theme="@style/FullscreenActionBarStyle"
              android:name="@string/my_activity_name"
              android:label="@string/my_activity_label"/>

This should add a toolbar to your activity that you can add items to and process events with, etc...

Yes, actionBar is deprecated and you should not use ListActivity but for smooth migration of legacy application. This code works – Hepcat
