Question

这是我的menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:id="@+id/menu_search"
        android:actionViewClass="com.actionbarsherlock.widget.SearchView"
        android:showAsAction="always|withText"
        android:title="Search"/>

</menu>

我试图在

中充气menu.xml

MainActivity.java

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        super.onCreateOptionsMenu(menu);
        MenuInflater inflater=new MenuInflater(getBaseContext());
        inflater.inflate(R.menu.menu, menu);

        return true;
    }

但是logcat会抛出错误

我还将主题保持为android:theme="@style/Theme.Sherlock.Light"

如何解决此错误？

Answer 1

添加已注释的代码部分并不能完全解决问题，但这很好。

   @Override
        public boolean onCreateOptionsMenu(Menu menu) {
            super.onCreateOptionsMenu(menu);
            MenuInflater inflater=new MenuInflater(getBaseContext());
            inflater.inflate(R.menu.menu, menu);
           // adding this section of code resolved the problem
            SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
            com.actionbarsherlock.widget.SearchView searchView = new com.actionbarsherlock.widget.SearchView(getSupportActionBar().getThemedContext());
            searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
            menu.findItem(R.id.menu_search).setActionView(searchView);
            return true;
        }

但它在我发布的logcat中显示了相同的警告，我发现这是ActionBarSherlock中众所周知的问题，以获取更多细节click here

无法实例化类：com.actionbarsherlock.widget.SearchView
