我正在使用ABS库开发一个应用程序.在两个fragmentActivities中,我需要在Actionbar中使用自定义视图.我的代码在ICS和JB中非常完美.但我在姜饼中测试并坠毁.

我的代码是下一个:

public class SearchContactActivity extends SherlockFragmentActivity {

    private EditText searchField;
    private ImageButton searchButton;


    @Override
    protected void onCreate(Bundle arg0) {
        super.onCreate(arg0);
        setContentView(R.layout.search_contacts);
        ActionBar actionBar = getSupportActionBar();
        actionBar.setDisplayHomeAsUpEnabled(true);
        View view = actionBar.getCustomView();//ICS & JB return the View OK, lower versions returns null
        searchField = (EditText) view.findViewById(R.id.editText_search);//here the app crash because view is null
        searchButton = (ImageButton) view.findViewById(R.id.button_search);

    }
}
