How to listen to each button in ListView in Android

Question

I'm new to Android. I have a ListActivity that include a ListView. The item in ListView is customized. The xml layout is

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/item"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingLeft="5dp"
        android:paddingTop="5dp"
        android:textSize="22sp" ></TextView>

    <TextView 
        android:id="@+id/item2" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:paddingBottom="10dp" 
        android:paddingLeft="10dp" 
        android:paddingTop="5dp" />

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="right" >

        <ImageButton
            android:id="@+id/imageButton1"
            android:layout_width="40dp"
            android:layout_height="40dp"
            android:background="@null"
            android:onClick="favoriteOnClick"
            android:src="@drawable/favorite_logo" />


    </RelativeLayout>

</LinearLayout>

If you want to use `favoriteOnClick` method to retrieve ImageButton click then in getView() of Custom Adapter just set Tag of ImageButton with position of List Item then retrieve it in `favoriteOnClick`using `getTag()`. — user370305, Aug 02 '13 at 08:51

Well, you can handle it in your ListView Adapter.

In method : public View getView(final int position, View convertView, ViewGroup parent) you can deserialize your ImageButton, and then set the OnClickListener. getView() method give you the position

you can use tag attached to each view to retrieve the position in listview.

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ImageButton ib = ...
    ib.setTag(new Integer(position));
    ib.setOnClickListener(myListener);
}

....

private OnClickListener myListener = new OnClickListener() {
    @Override
    public void onClick(View v) {
        int position = v.getTag(v.intValue());
    }
};
