Android Actionbar (actionbarcompat) Spinner Dropdown List ?

I am currently working ActionBar (ActionBarCompat) oriented project, I Need some Clarification about actionbar. I am using spinner layout like this,

Solution 1:

Try this code . In menu/main.xml :

<item
    android:id="@+id/menu_spinner1"
    android:showAsAction="always"
    android:orderInCategory="1"
    android:actionViewClass="android.widget.Spinner" >

in Activity :

privateMenuItemmSpinnerItem1=null;

@OverridepublicbooleanonCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.


    MenuInflater mi=getMenuInflater();
    mi.inflate(R.menu.main, menu);
    mSpinnerItem1 = menu.findItem( R.id.menu_spinner1);
    Viewview1= mSpinnerItem1.getActionView();
    if (view1 instanceof Spinner)
    {
        finalSpinnerspinner= (Spinner) view1;
        spinner.setAdapter(ad1);


        spinner.setOnItemSelectedListener(newOnItemSelectedListener() {

            @OverridepublicvoidonItemSelected(AdapterView<?> arg0, View arg1,
                    int arg2, long arg3) {
                // TODO Auto-generated method stub

            }

            @OverridepublicvoidonNothingSelected(AdapterView<?> arg0) {
                // TODO Auto-generated method stub

            }
        });

    }

    returntrue;
}

Solution 2:

I feel it's time to start migrating from ABS to ABC easily by ActionBarCompat library!

Solution for spinner (Dropdown list) using ActionBarCompat library

privatevoidsetupSpinner(MenuItem item) {
    //  item.setVisible(getSupportActionBar().getNavigationMode() == ActionBar.NAVIGATION_MODE_LIST);
        item.setVisible(ab.getNavigationMode() == ActionBar.NAVIGATION_MODE_LIST);

        Viewview= item.getActionView();
        Contextcontext= ab.getThemedContext(); //to get the declared themeif (view instanceof Spinner) {
            Spinnerspinner= (Spinner) view;

            ArrayAdapter<CharSequence> listAdapter =ArrayAdapter.createFromResource(context,
                    R.array.spinner_data,
                    R.layout.support_simple_spinner_dropdown_item);
            listAdapter.setDropDownViewResource(R.layout.support_simple_spinner_dropdown_item);
            spinner.setAdapter(listAdapter);



        }

make sure you have added following in style.xml:

<stylename="AppBaseTheme"parent="@style/Theme.AppCompat.Light"></style><stylename="AppTheme.MyActionBar"parent="@style/Widget.AppCompat.ActionBar">

More importantly: menu/main.xml should be:

<menuxmlns:android="http://schemas.android.com/apk/res/android"xmlns:yourapp="http://schemas.android.com/apk/res-auto" ><itemandroid:id="@+id/menu_spinner"yourapp:actionViewClass="android.widget.Spinner"android:visible="true"yourapp:showAsAction="always"/><itemandroid:id="@+id/action_contact"android:icon="@drawable/ic_action_user"yourapp:showAsAction="ifRoom"android:title="@string/action_contact"/><itemandroid:id="@+id/action_contact2"android:icon="@drawable/ic_action_user"yourapp:showAsAction="never"android:title="@string/aboutus"/></menu>

FYI ActionBarSherlock way we used before:

privatevoidsetupSpinner(MenuItem item) {
        item.setVisible(getActionBar().getNavigationMode() == ActionBar.NAVIGATION_MODE_LIST);
        Viewview= item.getActionView();
        if (view instanceof Spinner) {
            Spinnerspinner= (Spinner) view;
            spinner.setAdapter(ArrayAdapter.createFromResource(this,
                    R.array.spinner_data,
                    android.R.layout.simple_spinner_dropdown_item));
        }

comparing to ABS ABC you need to set listadapter as R.layout.support_simple_spinner_dropdown_item

Solution 3:

Try to change

android.R.layout.simple_spinner_item 

to

android.R.layout.simple_list_item_1

Solution 4:

I think you are using ActionBarCompat, which is only a sample project and is far not enough to be usable.

Try to use open source project ActionBarSherlock. I have been used it in several projects, and it is powerful and easy to use.

Solution 5:

If you will add spinner to your action bar through menu's xml like this

android:actionViewClass="android.widget.Spinner"

it will appear just like other menu actions - to the right.

If you want to make it appear to the left, you can do another way.

I'm doing it inside a fragment (but you can do it with activity), and using Toolbar, so my code is:

activity_main.xml (theme and popupTheme are important for arrow color) :

...
<android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
        app:subtitleTextColor="@android:color/white"
        app:titleTextColor="@android:color/white" />
...

action_bar_spinner_title.xml:

<?xml version="1.0" encoding="utf-8"?><TextViewxmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"android:id="@android:id/text1"style="?attr/spinnerDropDownItemStyle"android:layout_width="match_parent"android:layout_height="?attr/actionBarSize"android:ellipsize="marquee"android:singleLine="true"android:textColor="@android:color/white" />

action_bar_spinner_list.xml:

<?xml version="1.0" encoding="utf-8"?><CheckedTextViewxmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"android:id="@android:id/text1"style="?android:attr/spinnerDropDownItemStyle"android:layout_width="match_parent"android:layout_height="?attr/actionBarSize"android:background="@color/colorPrimary"android:ellipsize="marquee"android:singleLine="true"android:textColor="@android:color/white" />

Inside fragment:

privatestaticfinal String[] arItems = {"Item 1", "Item 2", "Item 3", };

private Toolbar toolbar;
private Spinner actionBarSpinner;

publicActionBarSpinnerFragment() {
}

@Nullable@Overridepublic View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container,
                         @Nullable Bundle savedInstanceState) {

    return inflater.inflate(R.layout.fragment_action_bar_spinner, container, false);
}

@OverridepublicvoidonStart() {
    super.onStart();

    finalActivityactivity= getActivity();
    if(activity != null) {
        ActionBaractionBar= ((AppCompatActivity) activity).getSupportActionBar();
        if (actionBar != null) {
            actionBar.setDisplayShowTitleEnabled(false);

            toolbar = activity.findViewById(R.id.toolbar);
            actionBarSpinner = newSpinner(actionBar.getThemedContext());
            ArrayAdapter<String> spinnerAdapter = newArrayAdapter<>(activity,
                    R.layout.action_bar_spinner_title, android.R.id.text1, arItems);
            spinnerAdapter.setDropDownViewResource(R.layout.action_bar_spinner_list);
            actionBarSpinner.setAdapter(spinnerAdapter);
            actionBarSpinner.setOnItemSelectedListener(newAdapterView.OnItemSelectedListener() {
                @OverridepublicvoidonItemSelected(AdapterView<?> parent, View view, int position, long id) {
                    FragmentManagerfragMngr= getFragmentManager();
                    if(fragMngr != null) {
                        FragmentTransactionfragTransact= fragMngr.beginTransaction();
                        fragTransact.replace(R.id.frag_frame,
                                TextViewFragment.newInstance(arItems[position]));
                        fragTransact.commit();

                    } else {
                        Log.w(LOG_TAG, "ActionBarSpinnerFragment: FragmentManager == null");
                    }
                }

                @OverridepublicvoidonNothingSelected(AdapterView<?> parent) {
                }
            });
            toolbar.addView(actionBarSpinner);
        } else {
            Log.w(LOG_TAG, "ActionBarSpinnerFragment.onStart: actionBar == null");
        }
    } else {
        Log.w(LOG_TAG,  "ActionBarSpinnerFragment.onStart: activity == null");
    }
}

@OverridepublicvoidonStop() {
    super.onStop();
    if(toolbar != null && actionBarSpinner != null) {
        toolbar.removeView(actionBarSpinner);
    } else {
        Log.w(LOG_TAG, "ActionBarSpinnerFragment: toolbar == " + toolbar
                + "; actionBarSpinner == " + actionBarSpinner);
    }
}
