Android – OnItemCLickListener not working in listview

androidlistview

Activity class code:

conversationList = (ListView)findViewById(android.R.id.list);
ConversationArrayAdapter conversationArrayAdapter=new  ConversationArrayAdapter(this, R.layout.conversation_list_item_format_left, conversationDetails);
conversationList.setAdapter(conversationArrayAdapter);
conversationList.setOnItemClickListener(new AdapterView.OnItemClickListener(){ 
    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
        Log.d("test","clicked");
    }
});

The getView function in the Adapter class:

if (v == null) {                                
    LayoutInflater vi = (LayoutInflater)ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    if(leftSideMessageNumber.equals(m.getTo())) {
        v = vi.inflate(R.layout.conversation_list_item_format_left, null);
    } else {
        v = vi.inflate(R.layout.conversation_list_item_format_right, null);
    }
}

Is there a problem with using two xmls while inflating?

I just found a solution from here, but by deep clicking.

If any row item of list contains focusable or clickable view then OnItemClickListener won't work.

The row item must have a param like android:descendantFocusability = "blocksDescendants".

Here you can see an example of how your list item should look like. Your list item xml should be... row_item.xml (your_xml_file.xml)

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:baselineAligned="false"
    android:descendantFocusability="blocksDescendants"
    android:gravity="center_vertical" >

    // your other widgets here

</LinearLayout>

Here's what I created to hold the images that my app is currently displaying. Please note that the "Log" object in use here is my custom wrapper around the final Log class inside Android.

Android – override or implement a supertype method [ERROR]

You extend FragmentActivity but don't make use of fragments.

You have 2 options:

1st create fragment extending ListFragment and this is were You implement onClick methods

2nd extend ListActivity instead
