Opening PlacePicker on SearchView single click

Question

I'm using SearchView as below in my code :

xml :

<android.support.v7.widget.SearchView
        android:id="@+id/searchView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:clickable="false"
        android:focusable="false"
        app:iconifiedByDefault="false"
        app:queryBackground="@color/transparant"
        app:queryHint="@string/search"
        app:searchIcon="@drawable/ic_search">

Java :

 mSearchView = (SearchView) rootView.findViewById(R.id.searchView);
 txtSearchText = (TextView) mSearchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
 txtSearchText.setOnClickListener(this);

onCLick :

case R.id.search_src_text:
     loadPlacePicker();
break;

But, the issue is SearchView needs a double click to open up PlacePicker. I need to open PlacePicker on the single onClick Event of SearchView. How do I do that?

Answer 2

You need to change the value of searchView attribute clickable & focusable to true

<android.support.v7.widget.SearchView
    android:id="@+id/searchView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:clickable="true"
    android:focusable="true"
    app:iconifiedByDefault="false"
    app:queryBackground="@color/transparant"
    app:queryHint="@string/search"
    app:searchIcon="@drawable/ic_search">
