Compare the performance with different layout with same ui.
Include five type of view
| Mode | Explain |
|---|---|
| Empty | just View(Context), empty view for compare. |
| Constraint | Use ConstraintLayout for root view with flat hierarchy |
| Normal | Use RelativeLayout for root view with nested hierarchy |
| Simple | Use RelativeLayout for root view with flat hierarchy |
| Custom | Use CustomViewGroup with java code, flat hierarchy |
| Total Custom | Same with Custom, skip some measure step |
Usage With Source Code
- Run app, open MainActivity.
- Click “jump tradtion”, Click “start test”
- After a few minutes, Test Result will show in MainActivity.
Some Test Result (nano seconds)
