ListView long click not working when a button is in list

Question

I have a ListView with custom list adapter. It has OnItemClickListener and OnItemLongClickListner which used to work fine. After then, I had to put a button in the layout of list item and the item click and long click listener stopped working. Here is my sample code:

ListView lv=(ListView)findViewbyId(R.id.listview); 
lv.setAdapter(listviewadapter);
lv.setOnItemLongClickListener(new OnItemLongClickListener() {
            @Override
            public boolean onItemLongClick(AdapterView<?> parent, View view,int position, long id) {
            // My code
            }
});

This used to work fine before adding the button in the layout of list item:

<?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="wrap_content"
    android:orientation="horizontal" 
    android:padding="2dp"
    >
    <TextView
        android:id="@+id/symbol_name"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="2.5"
        android:layout_gravity="left"
        />
    <TextView
        android:id="@+id/ltp"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_gravity="right"
        android:layout_weight="1"
        />
    <TextView
        android:id="@+id/change_in_perc"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_gravity="right"
        android:layout_weight="1"
        />

    <TextView
        android:id="@+id/volume"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_gravity="right"
        android:layout_weight="1"
        />

    <ImageButton
        android:id="@+id/chart"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_gravity="right"
        android:layout_weight="0.5"
        android:src="@drawable/charts"
        android:contentDescription="Chart Link"
        />
</LinearLayout>

I tried changing inline listener to implementing onItemLongClickListener on activity but no success till now. Thanks.

Answer 1

Your image button is probably taking focus when you click on list item.

So Add this

android:descendantFocusability="blocksDescendants" 

to your root element

http://developer.android.com/reference/android/view/ViewGroup.html#attr_android:descendantFocusability

android:descendantFocusability

Defines the relationship between the ViewGroup and its descendants when looking for a View to take focus.

Must be one of the following constant values.

Constant    Value   Description
beforeDescendants   0    The ViewGroup will get focus before any of its descendants.
afterDescendants    1    The ViewGroup will get focus only if none of its descendants want it.
blocksDescendants   2    The ViewGroup will block its descendants from receiving focus.
This corresponds to the global attribute resource symbol descendantFocusability.

Answer 2

did you set the android:longClickable="true" in the xml and the listview.setLongClickable(true); in the code ?
