I have been trying to animate a spannablestringbuilder. However, I get this message from the Devices Logcat: "PropertyValuesHolder﹕ Method setAlpha() with type float not found on target class class".
Any ideas of how to animate a pure string at all?
Code of what I have been doing:
private static void fadeEnhancedText(Context context,TextView labText, TextView labEnchangedText,
int defaultColor) {
//animation add objectanimation
SpannableStringBuilder mSpannableStringBuilder=
new SpannableStringBuilder(labEnchangedText
.getText().toString());
mSpannableStringBuilder.setSpan(mForegroundColorSpan, mMatcher.start(),
mMatcher.end(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
labText.setText(labEnchangedText.getText().toString());
labText.setVisibility(View.GONE);
//TODO spannable problem fader doesn't work fully
labEnchangedText.setText(mSpannableStringBuilder, TextView.BufferType.SPANNABLE);
mAnimationSet.play(fadeIn(labEnchangedText,mSpannableStringBuilder)).
after(fadeOut(labEnchangedText,
labText,
defaultColor,mSpannableStringBuilder));
mAnimationSet.start();
}
private static ObjectAnimator fadeIn(TextView textView, SpannableStringBuilder spannableStringBuilder)
{
ObjectAnimator animation = ObjectAnimator.ofFloat(spannableStringBuilder.getSpans(mMatcher.start(),
mMatcher.end(),textView.getClass()), "alpha",0f,1f);
animation.setDuration(300);
return animation;
}
private static ObjectAnimator fadeOut(final TextView textView, final TextView currentView, final int defaultColor,
final SpannableStringBuilder spannableStringBuilder)
{
//textView.setTextColor(Color.rgb(177, 24, 46));
ObjectAnimator animation = ObjectAnimator.ofFloat(spannableStringBuilder.getSpans(mMatcher.start(),
mMatcher.end(),textView.getClass()), "alpha",1f,0f);
animation.addListener(new Animator.AnimatorListener() {
@Override
public void onAnimationStart(Animator animation) {
}
@Override
public void onAnimationEnd(Animator animation) {
textView.setTextColor(defaultColor);
currentView.setVisibility(View.VISIBLE);
}
@Override
public void onAnimationCancel(Animator animation) {
}
@Override
public void onAnimationRepeat(Animator animation) {
}
});
animation.setRepeatCount(4);
animation.setDuration(300);
return animation;
}
