该类型的方法 startActivity(Intent) 未定义？

所以我试图通过按一个小部件来启动一个活动。我不断遇到错误“照片类型的方法 startActivity(Intent) 未定义”，非常感谢任何帮助！我的班级代码如下：

package com.natehoch96.widgets.iOS;

import android.appwidget.AppWidgetProvider;
import android.content.Intent;


public class Photos extends AppWidgetProvider {

    Intent myIntent = new Intent(android.provider.Settings.ACTION_SETTINGS);
    {startActivity(myIntent); }

}

您需要在 AppWidgetProvider 类中实现 onUpdate() 和 onReceive() 方法，如下所示：

public void onUpdate(Context context, AppWidgetManager appWidgetManager, 
    int[] appWidgetIds) {
    final int N = appWidgetIds.length;
    for (int i=0; i<N; i++) {
        int appWidgetId = appWidgetIds[i];

        //Get the views for your widget layout
        RemoteViews views = new RemoteViews(context.getPackageName(), 
            R.layout.my_widget);

        //Create a pending intent for a widget click
        Intent intent = new Intent(context, Photos.class);
        intent.setAction("PhotosAction");
        PendingIntent pendingIntent = 
            PendintIntent.getBroadcast(context, 0, intent, 0);
        views.setOnClickPendingIntent(R.id.widget_click_view, pendingIntent);

        appWidgetManager.updateAddWidget(appWidgetId, views);
    }
}

然后编写 onReceive() 方法来接收待处理的意图并启动相关活动：

public void onReceive(Context context, Intent intent) {
    super.onReceive(context, intent);

    if (intent.getAction().equals("PhotosAction") {
        //Received photos action action, start your target activity
        Intent i = new Intent(android.provider.Settings.ACTION_SETTINGS);
        i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);
    }
}
