B4A Library NineOldAndroids

This is my version of the NineOldAndroids lib for B4A. It's free and provided with the Java source code.

This library offers more possibilities of animation than AnimationPlus (rotation or translation on more than one axis for 3D effect, animation step by step with events for each step, synchronization between animations, ability to change the view size and contents during the animation, etc.).

It works with all versions of Android >= 2 and with all views, even custom ones.

v0.92: Initial release.
v0.92b: I changed the package name and repackaged the source to ease its compilation.
v0.93: I fixed a bug in noaObjectAnimator.InitializeFloat.

On my tablet (ASUS) too: 1280, since scale is 1

on my Huawei it is... -0

So I must set it using:
GetDeviceLayoutValues.Height * GetDeviceLayoutValues.Scale

but this also seems conditioned by the orientation of the device, when you create an animation.

Note that you have "Density" in B4A to get the density.

Ok but so it is... homogeneous? I don't know which term I should use

GetDeviceLayoutValues.Height * GetDeviceLayoutValues.Scale

GetDeviceLayoutValues.Height * GetDeviceLayoutValues.Scale

They return the same value (the value comes from context.getResources.getDisplayMetrics). Density is just shorter.

This library offers more possibilities of animation than AnimationPlus (rotation or translation on the Z axis for 3D effect

Since PROPERTY_TRANSLATION_Z does not exist, should I use PROPERTY_SCALE_X - PROPERTY_SCALE_Y to simulate a translation on Z?

Understood the answer

Since PROPERTY_TRANSLATION_Z does not exist, should I use PROPERTY_SCALE_X - PROPERTY_SCALE_Y to simulate a translation on Z?

PROPERTY_SCALE is not for translation. And it's not possible to translate along the Z axis before Android API 21 so it's not included in this library. The CameraDistance property can be used for this purpose, but I did not test the effective result. Under most recent Android versions (API >=21), you can try "setTranslationZ" with JavaObject.

PROPERTY_SCALE is not for translation.

I tried using it for a "simulation" of translation Z, without big success

You library is really powerful, @Informatix:
