Example 5 with DecelerateInterpolator

use of android.view.animation.DecelerateInterpolator in project SimplifyReader by chentao0707.

the class CaptureActivity method onCameraPreviewSuccess.

private void onCameraPreviewSuccess() {
    initCrop();
    captureErrorMask.setVisibility(View.GONE);
    ViewHelper.setPivotX(captureScanMask, 0.0f);
    ViewHelper.setPivotY(captureScanMask, 0.0f);
    mScanMaskObjectAnimator = ObjectAnimator.ofFloat(captureScanMask, "scaleY", 0.0f, 1.0f);
    mScanMaskObjectAnimator.setDuration(2000);
    mScanMaskObjectAnimator.setInterpolator(new DecelerateInterpolator());
    mScanMaskObjectAnimator.setRepeatCount(-1);
    mScanMaskObjectAnimator.setRepeatMode(ObjectAnimator.RESTART);
    mScanMaskObjectAnimator.start();
}
