The swiperefreshlayout implemented by Android enters automatic refresh for the first time

Seeing that the Android version almost achieved this effect, I realized it myself.

Let's start with a renderings

Implementation method:

Method 1:

① In the onwindowfocuschanged() method, set the refresh status to true

② Set the refresh status to false after data acquisition

Method 2:

① After calling the mshiperefreshlayout. Measure() method, set the refresh status to true

② Set the refresh status to false after data acquisition

Note: the purpose of the first step of methods 1 and 2 is to set the refresh status to true after the swipererefreshlayout is drawn. Otherwise, in most cases, the swipererefreshlayout refresh ball will not be displayed.
