  </RelativeLayout>

this two lines are ij relative latout.

I think you want this ... just need to add onClick() event on chat image and then on clicking set visibility of TextView to invisible by code.

TextView _text= (TextView)findViewById(R.id.task_list_chat_text);
        _text.setVisibility(TextView.INVISIBLE);

When you click on chat button in the list view you should setTest="" blank for both remove it. It may be solution of this problem.
