我在我的代码中使用SearchView，如下所示：
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？

您需要更改searchView属性的值clickable＆amp;专注于真实
<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:queryBackground="@color/transparant"
app:queryHint="@string/search"
app:searchIcon="@drawable/ic_search">
