如何从Android主屏幕小部件发起活动 [英] How to launch activity from android home screen widget

问题描述

我拼命试图让我的头部包裹着如何实现主屏幕小部件。现在，我（终于）能够得到的一个按钮preSS建立在清单的意图过滤器我小部件响应按钮。

I am desperately trying to get my head wrapped around how to implement home screen widgets. Right now, I (finally) was able to get a button on my widget respond to a button press setting up an intent filter in the manifest.

不过，我不能为我的生活弄清楚如何启动活动按钮时，pssed $ P $。基本上，这里的code，我有：

However, I cannot for the life of me figure out how to launch an activity when the button is pressed. Basically, here's the code i have:

 @Override 
 public void onReceive(Context context, Intent intent) 
 { 
      super.onReceive(context, intent); 
      if(intent.getAction().equals("com.bic.search.searchWidget.CLICK")) 
      { 
           Toast.makeText(context, "It works!!", Toast.LENGTH_SHORT).show(); 
      } 
 } 

我真正想做的事情，虽然是开始一个新的活动，不显示敬酒消息。我知道它是与未决的意图，但我无法弄清楚如何得到那个工作。

What I really want to do, though, is start a new activity, not display a toast message. I know it has something to do with pending intents, but I can't figure out how to get that to work.

任何帮助和样品code将AP preciated。由于一吨到谁回答了这个！

Any help and sample code would be appreciated. Thanks a ton to whoever answers this!

推荐答案

那么，你的应用程序插件应该已经有一个 PendingIntent 你绑到按钮。取而代之的是 PendingIntent 触发一个的BroadcastReceiver ，让它成为一个 PendingIntent 启动了一个活动。

Well, your app widget should already have a PendingIntent that you tied to the button. Instead of a PendingIntent that triggers a BroadcastReceiver, have it be a PendingIntent that starts up an Activity.
