Android: ListView add gradient for each row

I want to add gradient for each row. What I've tried to do is on listview label put this attribut, android:background="@drawable/mygradient". But All I get is this gradient displayed all along the list. What I want is this gradient to be displayed for each item.

Thanks in advance

You can provide a custom adapter for your list view and set the gradient as the background in its getView method. Something like this:

public class MyAdapter extends BaseAdapter {
    List<MyDataType> myData;
    Context context;

    public MyAdaptor(Context ctx, List<MyDataType> myData) {
        this.myData = myData;
        this.context = ctx;
    }

    public int getCount() { return myData.size() };
    public Object getItem(int pos) { return myData.get(pos); }
    public long getItemId(int pos) { return 0L; }

    public View getView(int pos, View convertView, ViewGroup parent) {
        //this is where you can customise the display of an individual
        //list item by setting its background, etc, etc.

        ...

        //and return the view for the list item at the end
        return <List item view>;
    }
}

Then you can set this adapter as the adapter for your list:

ListView myList = <initialise it here>
myList.setAdapter(new MyAdapter(getContext(), listData);

Now whenever a list item needs to be displayed, getView method will be called, where you'll perform all the necessary display customisation, including setting the background.

Instead of setting background property set Selector of list, as below:

android:listSelector="@drawable/list_selector_background"
