}|code-block|syntax|javascript|228609|我认为它相当丑陋，所以如果有人更好的想法，请告诉我:)|228610|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Just found an ugly way to make it work (read comments to see differences):

<pre><code>public class HomepageActivity extends Activity {
 // Declaring SearchView as an instance object
 private SearchView searchView;

 @TargetApi(11)
 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
 MenuInflater inflater = getMenuInflater();
 inflater.inflate(R.menu.projectslist, menu);

 if(Build.VERSION.SDK_INT &gt;= 11) {
 SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
 // Using instance var instead of local var
 searchView = (SearchView) menu.findItem(R.id.homepage_search).getActionView();
 ComponentName component = new ComponentName(this, SearchActivity.class);
 searchView.setSearchableInfo(searchManager.getSearchableInfo(component));
 searchView.setIconifiedByDefault(true);
 // Setting query is not anymore required
 //searchView.setQuery("", false);
 }

 return super.onCreateOptionsMenu(menu);
 }

 […]

 @TargetApi(11)
 @Override
 protected void onRestart() {
 super.onRestart();
 // Do not need to recreate menu
 /*if(Build.VERSION.SDK_INT &gt;= 11)
 invalidateOptionsMenu();*/
 if(Build.VERSION.SDK_INT &gt;= 11) {
 // Calling twice: first empty text field, second iconify the view
 searchView.setIconified(true);
 searchView.setIconified(true);
 }
 launchAsynchronousImageDownload();
 }
}
</code></pre>

It's pretty ugly, I think, so if anybody as a better idea, just tell me :)

blocks|key|446646|text|您还可以尝试以下操作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|446647|searchView.setQuery("",+false);
searchView.clearFocus();|code-block|syntax|javascript|446648|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

You might also try the following:

<pre><code>searchView.setQuery("", false);
searchView.clearFocus();
</code></pre>

blocks|key|446655|text|searchView.setQuery("",+false);
searchView.setIconified(false);|type|code-block|depth|inlineStyleRanges|entityRanges|data|syntax|javascript|446656|unstyled|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|G|8|@]|9|@]|A|$B|C]]|$1|D|3|-4|5|E|7|H|8|@]|9|@]|A|$]]]|F|$]]

<pre><code>searchView.setQuery("", false);
searchView.setIconified(false);
</code></pre>

blocks|key|446684|text|我也有这个问题，如果我把它放在onPrepareOptionsMenu中，它就能工作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|446685|@Override
public+boolean+onPrepareOptionsMenu+(Menu+menu)+{

I had this problem too and it worked if I put it in onPrepareOptionsMenu.

<pre><code>@Override
public boolean onPrepareOptionsMenu (Menu menu) {
 SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
 searchView.setQuery("", false);
 // rest of code...
}
</code></pre>

blocks|key|446731|text|这对我很有效：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|446732|首先，我在活动的顶部声明了菜单项变量：|446733|private+MenuItem+mSearchMenuItem;|code-block|syntax|javascript|446734|我在OnCreateOptionsMenu()中定义了这个变量：|446735|mSearchMenuItem+=+menu.findItem(R.id.action_search);|446736|我在onResume()中声明了invalidateOptionsMenu()：|446737|@Override
protected+void+onResume()+{
++++invalidateOptionsMenu();
++++super.onResume();
}|446738|最后，我在onPrepareOptionsMenu()中的菜单项上调用了collapseActionView()。|446739|@Override

This worked for me:

First, I declared the menu item variable at the top of the activity:

<pre><code>private MenuItem mSearchMenuItem;
</code></pre>

I defined the variable in OnCreateOptionsMenu():

<pre><code>mSearchMenuItem = menu.findItem(R.id.action_search);
</code></pre>

I declared invalidateOptionsMenu() in onResume():

<pre><code>@Override
protected void onResume() {
 invalidateOptionsMenu();
 super.onResume();
}
</code></pre>

Lastly, I called collapseActionView() on the menu item in onPrepareOptionsMenu().

<pre><code>@Override
public boolean onPrepareOptionsMenu(Menu menu) {
 mSearchMenuItem.collapseActionView();

 return super.onPrepareOptionsMenu(menu);
}
</code></pre>

I've got 2 activites : the first, <code>HomepageActiviy</code>, have a search widget that search data using another activity, <code>SearchActivity</code>.

What I want to do is when I go back from <code>SearchActiviy</code> to <code>HomepageActivity</code>, the search widget go collapsed and with a empty text.

I've tried to do this following thing :

<pre><code>public class HomepageActivity extends Activity {
 @TargetApi(11)
 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
 MenuInflater inflater = getMenuInflater();
 inflater.inflate(R.menu.projectslist, menu);

 if(Build.VERSION.SDK_INT &gt;= 11) {
 SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
 SearchView searchView = (SearchView) menu.findItem(R.id.homepage_search).getActionView();
 ComponentName component = new ComponentName(this, SearchActivity.class);
 searchView.setSearchableInfo(searchManager.getSearchableInfo(component));
 searchView.setIconifiedByDefault(true);
 searchView.setQuery("", false);

 }

 return super.onCreateOptionsMenu(menu);
 }

 […]

 @TargetApi(11)
 @Override
 protected void onRestart() {
 super.onRestart();
 if(Build.VERSION.SDK_INT &gt;= 11)
 invalidateOptionsMenu();
 launchAsynchronousImageDownload();
 }
}
</code></pre>

If the widget is well displayed as collapsed, the text in the widget still remember searched text (after I re-open the widget).
How can I reset the text of the widget?

Thanks for any help! ;)

Resetting Search Widget (SearchView) value

我有两个活动:第一个是HomepageActiviy，它有一个使用另一个活动SearchActivity搜索数据的搜索小部件。我想要做的是，当我从SearchActiviy返回到HomepageActivity时，搜索小部件崩溃了，并且显示了一个空文本。我试着做了以下事情：public class HomepageAc...
