android.support.v4.widget.SearchViewCompat 示例？

Question

我正在尝试在 API 8 应用程序中将 SearchViewCompat 与 ActionBarSherlock 一起使用。

public boolean onCreateOptionsMenu(Menu menu) {
    MenuItem item = menu.add("Search")
        .setIcon(isLight ? R.drawable.ic_search_inverse : R.drawable.ic_search)
        .setActionView(R.layout.collapsible_edittext);
    item.setShowAsAction(
        MenuItem.SHOW_AS_ACTION_ALWAYS | 
        MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);

    // To use SearchViewCompat, I need to add it to the Menu item as well:
    View searchView = SearchViewCompat.newSearchView(this);
    // ...
    SearchViewCompat.setOnQueryTextListener(...);
    // ...
    item.setActionView(searchView);

请注意，顶部和底部代码都需要调用setActionView()。这是否意味着无法进行搜索？

如果您使用的是 ActionBarSherlock 库版本 4.2，则可以将 API 11 SearchView 小部件替换为 ActionBarSherlock SearchView 小部件以使其向后兼容:

search.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/menu_search"
        android:icon="@drawable/ic_action_search"
        android:title="@string/description_search"
        android:orderInCategory="0"
        android:actionViewClass="com.actionbarsherlock.widget.SearchView"
        android:showAsAction="ifRoom|collapseActionView" /> 
</menu>

Activity 类

//IMPORTANT!!!
import com.actionbarsherlock.widget.SearchView;

...

@Override 
public boolean onCreateOptionsMenu(Menu menu) {
    super.onCreateOptionsMenu(menu);
    getSupportMenuInflater().inflate(R.menu.search, menu);
    setupSearchMenuItem(menu);
    return true;
}

private void setupSearchMenuItem(Menu menu) {
    MenuItem searchItem = menu.findItem(R.id.menu_search);
    if (searchItem != null) {
        SearchView searchView = (SearchView) searchItem.getActionView();
        if (searchView != null) {
            SearchManager searchManager = 
                 (SearchManager) getSystemService(SEARCH_SERVICE);
            searchView.setSearchableInfo(
                searchManager.getSearchableInfo(getComponentName()));
            }
        }
    }
}
