Hi All,
I have a ListView specified by list_item.xml Now I need to change the Image in my list inside onListItemClick. How to achieve this?
//list_item.xml
<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/play"
android:id="@+id/img"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:id="@+id/txt"
/>
</LinearLayout>
I have a Custom Adapter to populate my list. Code below is the adapter.
public class MyCustomAdapter extends ArrayAdapter<String> {
public MyCustomAdapter(Context context, int textViewResourceId,
String[] objects) {
super(context, textViewResourceId, objects);
// TODO Auto-generated constructor stub
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
LayoutInflater inflater=getLayoutInflater();
View row=inflater.inflate(R.layout.list_item, parent, false);
TextView label=(TextView)row.findViewById(R.id.txt);
label.setText(Sounds[position]);
ImageView icon=(ImageView)row.findViewById(R.id.img);
icon.setMaxHeight(32);
icon.setMaxWidth(32);
icon.setPadding(2, 1, 5, 1);
icon.setImageResource(R.drawable.play);
return row;
}
}
And in onCreate I do the following
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try
{
setListAdapter(new MyCustomAdapter(this, R.layout.list_item, Sounds));
//Sounds --> String array
}
catch(Exception e)
{
e.printStackTrace();
}
}
Now when any row is selected, I need to change the image associated with the selected view. Your help is appreciated. Thanks.
