Question

我正在创建自定义窗口标题。我用requestWindowFeature和setFeatureInt做了但不行。我不知道这有什么问题。我无法找到错误的来源。

public abstract class MegaActivity extends Activity {
    private final int layoutID;
    public MegaActivity(final int layoutID) {
        super();
        this.layoutID = layoutID;
    }

    @Override
    protected void onCreate(final Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
        setContentView(layoutID);
        getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.window_title);
    }
}

public class AsyncTaskTestActivity extends MegaActivity {

    public AsyncTaskTestActivity() {
        super(R.layout.main);
    }
}

window_title.xml

    <ImageView
        android:id="@+id/header"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" android:src="@drawable/megadict_icon"/>
    <TextView android:layout_width="wrap_content" android:id="@+id/textView1" android:layout_height="wrap_content" android:text="@string/appTitle" android:textSize="16dip" android:textColor="@color/white"></TextView>

</LinearLayout>

错误

是AsyncTaskTestActivity启动器活动吗？你是怎么调用那个活动的？问题可能是你的布局，检查你的布局，是否包含错误？如果你仍然得到错误，请暂时注释requestWindowFeature及其相关信息资源问题？你的问题答案可以帮到你
