Android : Custom Progress bars and Gauges

I want to create custom progress widgets as shown in the image. After some research I found:

• For needle gauge i can modify this widget


• For Horizontal Progress meters i should customize the android native progress bar.


• For Water indicator i should create a custom widget using android canvas.

My Question is: Am I using the correct way to create and implement these widgets? Or Any better recommendations or tutorials which you think might help me create these especially the "Water Indicator" and Customizing the Android Native progress bar.

Thanks.
