TextInputLayout浮动标签显示缓慢

我已经申请了安卓TextInputLayout，它工作正常。但是当出现文本输入布局时，编辑文本变得非常慢。我也改变了提示颜色，但它不起作用。

布局XML:

 <android.support.design.widget.TextInputLayout
                android:id="@+id/register_input_layout_password"
                android:layout_width="match_parent"
                android:layout_height="wrap_content">
            <EditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:maxLength="15"
                android:lines="1"
                android:id="@+id/Register_fragment_passwo_field"
                android:hint="Password"
                android:layout_gravity="center_vertical"
                android:paddingLeft="35dp"
                android:textColor="#ffffff"
                android:textColorHint="@android:color/white"
                android:layout_marginTop="5dp" />
            </android.support.design.widget.TextInputLayout>

依赖性 : compile 'com.android.support:design:23.0.1'

   <!-- if You Can Change Color of TextInputLayout Like this-->
    <style name="TextLabel" parent="TextAppearance.AppCompat">
        <!-- Hint color and label color in FALSE state -->
        <item name="android:textColorHint">@color/Color Name</item> 
        <item name="android:textSize">20sp</item>
        <!-- Label color in TRUE state and bar color FALSE and TRUE State -->
        <item name="colorAccent">@color/Color Name</item>
        <item name="colorControlNormal">@color/Color Name</item>
        <item name="colorControlActivated">@color/Color Name</item>
     </style>

如果您更改动画时间，则自定义EditText像这样：

public class FloatingEditText extends FrameLayout{

      animation = new AnimatorSet();
      ObjectAnimator move =
          ObjectAnimator.ofFloat(mHintTextView, "translationY", mHintTextView.getHeight() / 8, 0);
      ObjectAnimator fade;
      if (mEditText.isFocused()) {
        fade = ObjectAnimator.ofFloat(mHintTextView, "alpha", 0, 1);
      } else {
        fade = ObjectAnimator.ofFloat(mHintTextView, "alpha", 0, 0.50f);
      }
      animation.playTogether(move, fade);
}
