我正在尝试在searchView上开发一个actionBar的应用。现在，在Galaxy S4上工作正常，但在星系S2上它正在崩溃。
也许是关于＆＃34; ActionBarActivity＆＃34;但我使用碎片。我不知道为什么会这样。这是我的活动：
public class SendSms extends Fragment implements OnClickListener, OnItemClickListener ,SearchView.OnQueryTextListener {
public static final String LOG = "myLog";
SearchView mSearchView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
setHasOptionsMenu(true);
v = inflater.inflate(R.layout.send_sms123, container,false);
context = getActivity();
}
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.main, menu);
inflater = context.getMenuInflater();
MenuItem searchItem = menu.findItem(R.id.action_search);
mSearchView = (SearchView) searchItem.getActionView();
mSearchView.setOnQueryTextListener(this);
mSearchView.setOnSearchClickListener(this);
mSearchView.setQueryHint("Type name or number");
menu.add("Load contact").setOnMenuItemClickListener(new OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
loadContactAgain();
return false;
}
});
menu.add("Clean contact").setOnMenuItemClickListener(new OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
DeleteAll();
return false;
}
});
//TEMP
menu.add("Developer mode").setOnMenuItemClickListener(new OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
developerMode();
return false;
}
});
menu.add("Stop service").setOnMenuItemClickListener(new OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
context.stopService(new Intent(context,ServiceSender.class));
return false;
}
});
super.onCreateOptionsMenu(menu,inflater);
}
@Override
public boolean onQueryTextSubmit(String query) {
}
@Override
public boolean onQueryTextChange(String newText) {
adapterContact.filter(newText);
if(!adapterContact.isEmpty())
setVisibiltyListBar(newText);
return false;
}
菜单/主：
<item android:id="@+id/action_search"
android:title="Search"
android:icon="@android:drawable/ic_menu_search"
android:showAsAction="always"
android:actionViewClass="android.widget.SearchView" />
这是LogCat：

答案 0 :(得分：0)
如果您使用ActionBarActivity，则必须使用support-v7 SearchView：
<item android:id="@+id/action_search"
android:title="Search"
android:icon="@android:drawable/ic_menu_search"
android:showAsAction="always"
android:actionViewClass="android.support.v7.widget.SearchView" />
然后您可以通过
检索它MenuItem searchItem = menu.findItem(R.id.action_search);
mSearchView = (SearchView) MenuItemCompat.getActionView(searchItem);
确保更改SearchView，OnQueryTextListener等
