属性动画设置延迟后，如果在未开始前取消，会执行onAnimationStart方法,特此记录

public class AnimatorDelayTestActivity extends AppCompatActivity {

private View mTextView;
private ObjectAnimator translationY;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.animator_delay);
mTextView = findViewById(R.id.animator_test);
}

public void start(View view) {
translationY = moveView(mTextView, "translationY", 0, mTextView.getHeight(), 5000);
translationY.addListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationStart(Animator animation) {
super.onAnimationStart(animation);
Log.i("onAnimationUpdate", "start方法");
}

});
translationY.start();
}

public void cancel(View view) {
translationY.cancel();
}

private ObjectAnimator moveView(View view, final String attr, float start, float end, int delay) {
ObjectAnimator move = ObjectAnimator.ofFloat(view, attr, start, end);
move.setDuration(1000);
move.setStartDelay(delay);
return move;
}
}
