从其他包（主包）中的活动 A 中打开不同包/文件夹中的活动 B

Question

I'm currently working on a mobile app for our final project this sem. I just wanna know how to open an activity in a package from another activity from a different package.

Example:

FirstActivity in com.example.package1 SecondActivity in Package2 Package2 is inside in the com.example.package1

"I want to open SecondActivity when a button is clicked in FirstActivity"

The underlined class is the 2nd Activity and the highlighted one is the 1st activity.

Here's the code from the MM_Play.class (first activity)

Here's the code in the AndroidManifest.xml

I hope you can help to my problem. Stay safe always my fellow programmers.

Answer 1

Please try this way by import second activity class in first activity

Inside onClickListener in First activity

Intent intent = new Intent(FirstActivity.this, SecondActivity.class);
startActivity(intent)

Answer 2

Add activity in your manifest file like this:

<activity
        android:name=". Your folder name where Second Activity is present then . 
        (Second Activity Name)"/>

In java file like this:

Intent intent = new Intent(FirstActivit.this,Second activity.class);
start activity(intent)
