在 SearchView 上单击打开 PlacePicker

Question

我在我的代码中使用 SearchView 如下：

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;

但是，问题是 SearchView 需要双击才能打开 PlacePicker。 我需要在 SearchView 的单个 onClick 事件上打开 PlacePicker。我该怎么做？

Answer 1

你需要将searchView属性clickable & focusable的值改为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">
