到目前为止,我编码:

public class WidgetActivity extends AppWidgetProvider
{    
    public void onReceive(Context context, Intent intent)
    {


        String action = intent.getAction();
        if (AppWidgetManager.ACTION_APPWIDGET_UPDATE.equals(action))
        {

            RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_activity);

            Intent settingsIntent = new Intent(context, Info.class);
            PendingIntent clickPendIntent = PendingIntent.getActivity
                    (context, 0, settingsIntent, PendingIntent.FLAG_UPDATE_CURRENT);
            views.setOnClickPendingIntent(R.id.Widget, clickPendIntent);





            AppWidgetManager.getInstance(context).updateAppWidget(intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS), views);


        }
    }
}

没有成功我点击屏幕上的小部件并且没有任何内容启动。我错过了什么吗?

答案 0 :(得分:1)

使用PendingIntent方法设置确保设置onUpdate()的代码。这样可以确保只要将小部件放在主屏幕上,就会设置PendingIntent

所以:

public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgets) {
    RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_activity);
    Intent intent = new Intent(context, Info.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
    remoteViews.setOnClickPendingIntent(R.id.Widget, pendingIntent);

此外:

如果您还希望在首次将小部件添加到主屏幕时自动弹出信息Activity,则应阅读this userful piece of information
