我要调用一个活动，是在另一个包......

I want to call an activity that is in another package....

比方说我有一个活动（活动1）在我的包（包1），我需要调用另一个活动（活性2）在另一包（包2）从我的活动1。

Say for example I have an Activity(activity1) in my package(package1) and I need to call another Activity(activity2) in another package(package2) from my activity1..

我试图导入程序包2在我的包1，但它没有工作... 谁能回答我，并提供一些示例code？

I have tried to import the package2 in my package1 but it did not work... Can anyone answer me and provide some sample code?

推荐答案

看 Android:启动一个活动为不同的第三方应用

final Intent intentDeviceTest = new Intent("android.intent.action.MAIN");                
intentDeviceTest.setComponent(new ComponentName("fm.last.android","fm.last.android.LastFm"));
startActivity(intentDeviceTest);

在这里你可以改变这取决于你的情况下，意图视图。

where you can change the intent to VIEW depending on your case.
