如何从Android AppWidget启动Activity? [英] How to start Activity from Android AppWidget?

问题描述

这样的代码效果很好.

    Intent configIntent = new Intent (context, WidgetConfigActivity.class);
    configIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
    PendingIntent pIntent = PendingIntent.getActivity(context, 0, configIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    remoteView.setOnClickPendingIntent(R.id.btn, pIntent);

但是我想隐藏该按钮，因为活动将出现，所以我试图将意图发送给小部件本身，在onReceive()方法中执行隐藏组件，然后开始活动.问题是我无法在AppWidget中使用startActivity()函数.

But I want to hide that button befor activity will appear, so I'm triing to send intent to the widget itself, perform hiding components in onReceive() method and then start activity. Problem is that I can't use startActivity() function in AppWidget.

有什么解决办法吗?

推荐答案

问题是我无法在AppWidget中使用startActivity()函数.

Problem is that I can't use startActivity() function in AppWidget.

是的，可以.您将Context对象传递到AppWidgetProvider的onUpdate()(或onReceive())中–在该对象上调用startActivity().

Yes, you can. You are passed in a Context object into onUpdate() (or onReceive()) of your AppWidgetProvider -- call startActivity() on that.
