Question

让我们说我有一个listview作为我的主要活动。点击一个项目就会打开第二个活动。点击一个按钮就可以使用本教程中的volley库打开一个自定义列表视图（http://www.androidhive.info/2014/07/android-custom-listview-with-image-and-text-using-volley/ ）但是，单击第二个活动中的按钮以使用齐射打开我的列表视图，我的应用程序停止。我想到的问题始于清单，我将在下面发布。我有两个应用程序类，因为我正在使用Parse推送通知库。但是，只有一个应用程序可以声明在清单启动时打开。所以我在这个问题（how to handle multiple application classes in android）上实现了答案。就在这之后我的应用程序在打开第三个活动时一直停止。所以请帮助我实现这一目标。谢谢。

我从这里修改了AppController类（http://www.androidhive.info/2014/07/android-custom-listview-with-image-and-text-using-volley/）以扩展ParseApplication

＆＃13;

public class AppController extends ParseApplication {
	 
    public static final String TAG = AppController.class.getSimpleName();
 
    private RequestQueue mRequestQueue;
    private ImageLoader mImageLoader;
 
    private static AppController mInstance;
 
    @Override
    public void onCreate() {
        super.onCreate();
        mInstance = this;
    }
 
    public static synchronized AppController getInstance() {
        return mInstance;
    }
 
    public RequestQueue getRequestQueue() {
        if (mRequestQueue == null) {
            mRequestQueue = Volley.newRequestQueue(getApplicationContext());
        }
 
        return mRequestQueue;
    }
 
    public ImageLoader getImageLoader() {
        getRequestQueue();
        if (mImageLoader == null) {
            mImageLoader = new ImageLoader(this.mRequestQueue,
                    new LruBitmapCache());
        }
        return this.mImageLoader;
    }
 
    public <T> void addToRequestQueue(Request<T> req, String tag) {
        // set the default tag if tag is empty
        req.setTag(TextUtils.isEmpty(tag) ? TAG : tag);
        getRequestQueue().add(req);
    }
 
    public <T> void addToRequestQueue(Request<T> req) {
        req.setTag(TAG);
        getRequestQueue().add(req);
    }
 
    public void cancelPendingRequests(Object tag) {
        if (mRequestQueue != null) {
            mRequestQueue.cancelAll(tag);
        }
    }
}
