Android 将操作栏与Google Maps API v2集成

我正在尝试设置一个应用程序，允许用户查找本地业务和事件。我有一个工作地图，但是我很难将它集成到一个选项卡式的动作栏中。不幸的是，它说“不幸的是，[应用程序]已经停止。” 任何帮助都将不胜感激

ActionBarMain.java

@SuppressLint("NewApi")
public class ActionBarMain extends Activity implements TabListener {
    RelativeLayout rl;

    @Override

            rl = (RelativeLayout) findViewById(R.id.mainLayout);
            fragMentTra = getFragmentManager().beginTransaction();
            ActionBar bar = getActionBar();
            bar.addTab(bar.newTab().setText("Map").setTabListener(this));
            bar.addTab(bar.newTab().setText("Businesses").setTabListener(this));
            bar.addTab(bar.newTab().setText("Events").setTabListener(this));
            bar.addTab(bar.newTab().setText("Facebook").setTabListener(this));

            bar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM
                    | ActionBar.DISPLAY_USE_LOGO);

错误为“未找到类MainActivity”

您发布的类名为ActionBarMain，而清单文件显示MainActivity是您的主类

---

如果您的项目中没有任何Main活动，并且希望ActionBarMain成为您的第一个活动。然后在清单文件中将ActionBarMain替换为MainActivity。

谢谢。我从一个工作地图和一个工作选项卡式动作栏开始。只是把它们组合在一起的错误。那么它解决了问题了吗？这不是最后一个问题，但我能够解决它的其余部分，现在就可以开始运行了。再次感谢。
