Java Android小部件按钮根本不工作，如何使其工作？

我会说我对安卓一点经验都没有，以此作为前提

我只是想简单地将textView tv1更新为当按下按钮时从网络上抓取的一些数据，当按下按钮时，现在什么都没有发生，我不知道为什么

以下是我的provider类中必要的方法

public static String WIDGET_BUTTON = "com.beninga.android.mobilenexus.WIDGET_BUTTON";
RemoteViews remoteViews;
AppWidgetManager appWidgetManager;
ComponentName thisWidget;
Context context;
Player[] players;
private int[]  appwidgetIds;

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
    this.appWidgetManager = appWidgetManager;
    this.appwidgetIds = appWidgetIds;
    for(int i =0; i < appWidgetIds.length; i++) {
        remoteViews = new RemoteViews(context.getPackageName(), R.layout.activity_main);
        thisWidget = new ComponentName(context, MobileNexus.class);
        this.context = context;
        System.out.println("did this run");
        remoteViews.setOnClickPendingIntent(R.id.button, getRefreshPendingIntent());
        appWidgetManager.updateAppWidget(thisWidget, remoteViews);

    }
}
private PendingIntent getRefreshPendingIntent(){
        Intent intent = new Intent(context, getClass());
        intent.setAction(WIDGET_BUTTON);
        return PendingIntent.getBroadcast(context, 0, intent, 0);
    }

public void onReceive(Context context, Intent intent) {
    appWidgetManager = AppWidgetManager.getInstance(context);
    System.out.println(intent.getAction()+ "was recieved");
    if (intent.getAction().equals(WIDGET_BUTTON)) {
        remoteViews = new RemoteViews(context.getPackageName(), R.layout.activity_main);
        remoteViews.setOnClickPendingIntent(R.id.button, getRefreshPendingIntent());
        System.out.println("IT GOT CALLED");
        String url = findUrl();
        new RetrieveData().execute(url);


    }
    super.onReceive(context, intent);
}

按下按钮时，onclickpending从不触发操作

编辑：我明白了！删除INTERNET代码并执行此操作

PendingIntent pi = PendingIntent.getBroadcast(context,0, in,0);
        remoteViews.setOnClickPendingIntent(R.id.button,pi);

并将GetRefreshPending帐篷主体替换为

private PendingIntent getRefreshPendingIntent(){
        Intent in = new Intent(WIDGET_BUTTON);
        return PendingIntent.getBroadcast(context,0, in,0);

    }

显示您的

OnCreate

方法添加了我的OnCreate方法。现在告诉我您基本上想要实现什么？点击按钮会发生什么？我想将我的TextView tv1中显示的文本更改为我从网上抓取的内容。你为什么要使用广播接收器？你收到推送通知了吗？如果没有，那么我认为你走错了方向。要使用web url更新textview，只需一行代码。
