There is this widget for the ActionBar which called 'SearchView'. When it's not in use, it looks like this:
而当它在使用时,它看起来是这样的:
And when it's in use, it looks like this:
我想(编程的过程中)打开搜索查看(使处于使用状态)。
I want (programmatically of course) to open the searchview (make it "in use").
我试了几个功能,如:
SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
searchView.setOnQueryTextListener(this);
searchView.performClick();
searchView.requestFocus();

But none of those worked...
在XML中的搜索查看:
The SearchView in the XML:
<item android:id="@+id/menu_search"
android:title="Search"
android:icon="@drawable/ic_action_search"
android:showAsAction="ifRoom|collapseActionView"
android:actionViewClass="android.widget.SearchView" />
感谢名单的前期。
Thanx upfront.
展开搜索查看
与
searchView.setIconified(false);
和折叠它
searchView.setIconified(true);
您需要改变的值安卓showAsAction
从 ifRoom | collapseActionView
到总是
。该搜索查看
的属性安卓iconifiedByDefault
应真
,这是默认值,否则用户无法折叠搜索查看
后,这是编程扩展。
You need to change the value of android:showAsAction
from ifRoom|collapseActionView
to always
. The SearchView
's attribute android:iconifiedByDefault
should be true
, which is the default value, otherwise the user can not collapse the SearchView
after it was expanded programmatically.
