Android transmits data in a normal class (non-activity, mostly adapter) to a NULL solution: Transfer data in startactivity with intent

This is the bundle is not transmitting data, get to

This occurs because there is no context in the non-activity class, and the context is required to transfer data in the activity.

I have collected two solutions.

1.

Declare an activity (or context) in the activity that invokes the adapter.

Public static Activity mactivity;

And then assign a value to mactivity in the OnCreate function.

mactivity = this;

You can then invoke this static mactivity in adapter to start the activity.

Activity.mActivity.startActivity (intent);

The activity that starts this way is the data that can be obtained.

2.

Get a context startup activity directly.

GetContext (). StartActivity (intent);

This is also possible to obtain data, I think this method may be problematic, but the level is limited, do not know what the problem.

So that we can happily transfer data in non-activity.
