SwipeRefreshLayout works but the spinner won't show

Question

I'm having an issue using SwipeRefreshLayout, the functionality works perfectly but the spinner won't show. I've already used all the provided solutions out there but still nothing.

I don't like to use XML at all so I basically code everything and avoid it. I have a class extending SwipeRefreshLayout where I create the listView, add the adapter and configure the refresh action etc. My minimum API Level is 16.

If you guys need any further details or code please let me know and I'll be glad to provide them, any help is appreciated!

My activity

public class MainActivity extends Activity {

    private static MainActivity mainActivity = null;
    private MainView mainView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        mainView = new MainView(this);
        setContentView(mainView);
    }

    public static MainActivity getMainActivity() {
        return mainActivity;
    }
}

My main view:

public class MainView extends SwipeRefreshLayout {

    private ListView listView;

    public MainView(Context context) {
        super(context);

        final String [] objects = new String[] {"panda", "horse", "fox"};

        listView = new ListView(context);
        final ArrayAdapter arrayAdapter = new ArrayAdapter<String>(context, android.R.layout.simple_list_item_1, objects);
        listView.setAdapter(arrayAdapter);
        addView(listView);

        this.setOnRefreshListener(new OnRefreshListener() {
            @Override
            public void onRefresh() {
                objects[0] = "Big panda!";
                arrayAdapter.notifyDataSetChanged();
                setRefreshing(false);
            }
        });
    }

    @Override
    protected void onLayout(boolean changed, int l, int t, int r, int b) {
        int width = r - l;
        int height = b - t;

        listView.layout(0, 0, width, height);
    }
}

Answer 1

Hard to tell without seeing any code, but my gut tells me you need to make sure that the appropriate progress view is linked and you are setting the visibility to VISIBLE and INVISIBLE at the right times.

Answer 2

Here is a simple demo, with working progress on a coded SwipeRefreshLayout each time you Swipe it will add an item to the list

my Activity:

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        RelativeLayout container = (RelativeLayout) findViewById(R.id.container);

        CustomSwipeRefresh swipeRefresh = new CustomSwipeRefresh(this);
        container.addView(swipeRefresh);
        swipeRefresh.refreshData();
    }
}

with layout:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/container"
    tools:context="com.divshark.customswiperefresh.MainActivity">


</RelativeLayout>

Then i created CustomSwipeRefresh :

public class CustomSwipeRefresh extends SwipeRefreshLayout {

    private static final String TAG = CustomSwipeRefresh.class.getSimpleName();

    private static int MIN_LIST = 50;

    private List<String> mItems = new ArrayList<>();
    private Context mContext;

    private ListView listView;
    private ListAdapter mAdapter;

    public CustomSwipeRefresh(Context context){
        super(context);

        this.mContext = context;


        mAdapter = new ListAdapter(mContext, mItems);

        listView = new ListView(context);
        listView.setAdapter(mAdapter);
        listView.setBackgroundColor(Color.WHITE);
        listView.setDivider(null);
        listView.setDividerHeight(0);
        addView(listView);

        setOnRefreshListener(new OnRefreshListener() {
            @Override
            public void onRefresh() {

                setRefreshing(true);

                postDelayed(new Runnable() {
                    @Override
                    public void run() {

                        onRefreshData(true);

                        Log.d(TAG,"--- FINISHED REFRESHING ---");
                        setRefreshing(false);
                    }
                }, 2000);

            }
        });

    }

    public void refreshData(){
        onRefreshData(false);
    }

    /**
     * Called when the data is refreshed in the list
     */
    private void onRefreshData(boolean addItem){

        if(addItem){
            MIN_LIST++;
        }

        mItems.clear();

        for(int i = 0; i < MIN_LIST; i++){
            mItems.add("New item "+ Integer.toString(i + 1));
        }

        mAdapter.notifyDataSetChanged();
    }


    public class ListAdapter extends BaseAdapter{

        public List<String> mItems;
        public Context mContext;
        public LayoutInflater mInflater;

         class Holder{
            AppCompatTextView mTvItem;
        }

        public ListAdapter(Context context, List<String> items){

            this.mContext = context;
            this.mItems = items;
            this.mInflater = LayoutInflater.from(mContext);

        }

        @Override
        public int getCount() {
            return mItems.size();
        }

        @Override
        public Object getItem(int position) {
            return mItems.get(position);
        }

        @Override
        public long getItemId(int position) {
            return position;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {

            Holder holder ;

            if(convertView == null){
                holder = new Holder();
                convertView = mInflater.inflate(R.layout.item_row, parent, false);

                holder.mTvItem = (AppCompatTextView) convertView.findViewById(R.id.item);

                convertView.setTag(holder);
            }else{
                holder = (Holder) convertView.getTag();
            }

            String item = mItems.get(position);
            if(item != null){
                holder.mTvItem.setText(item);
            }

            return convertView;
        }
    }
}

and item layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent" android:padding="16dp">
<android.support.v7.widget.AppCompatTextView
    android:id="@+id/item"
    android:layout_width="wrap_content"
    android:layout_height="match_parent" />
</LinearLayout>

Hope this helps!
