Question

The android lockscreen widget that use 2 buttons that we can swipe from right to left or left to right is really cool!

Unfortunately, that’s not a public one, it his hidden in android.internal stuff…

I really would like to use it and tried to use the same source code than Android: http://www.devdaily.com/java/jwarehouse/android/core/java/com/android/internal/widget/RotarySelector.java.shtml

Unfortunately, a lot of things are related to internal and some variables (mRight) cannot be found and are not declared.

Also I am missing 2 files:
R.styleable.RotarySelector and R.styleable.RotarySelector_orientation

I cannot believe nobody succeed to use this cool stuff!

Any idea or link to follow?

Answer 1

I’m currently porting ICS NumberPicker and it took me a while to realize where mRight, mLeft… where coming from.. they come from View (which is like 3 classes up in the hierarchy).

To get those values you can use their corresponding public methods:

• getRight()
• getLeft()
• getTop()
• getBottom()
• getHeight()
• getWidth()
• getContext()

As for R stuff check the source, you may need values from attr.xml, styles.xml and themes.xml
