How to stop an animation (cancel() does not work)

Question

I need to stop a running translate animation. The .cancel() method of Animation has no effect; the animation goes until the end anyway.

How

Answer 1

What you can try to do is get the transformation Matrix from the animation before you stop it and inspect the Matrix contents to get the position values you are looking for.

Here are the api's you should look into

public boolean getTransformation (long currentTime, Transformation outTransformation)

public Matrix getMatrix ()

public void getValues (float[] values)

So for example (some pseudo code. I have not tested this):

Transformation outTransformation = new Transformation();
myAnimation.getTransformation(currentTime, outTransformation);
Matrix transformationMatrix = outTransformation.getMatrix();
float[] matrixValues = new float[9];
transformationMatrix.getValues(matrixValues);
float transX = matrixValues[Matrix.MTRANS_X];
float transY = matrixValues[Matrix.MTRANS_Y];
