        holder.NavigationTitle.setTypeface(tf);

Answer 1

try increasing the duration in your animation file ie slide_left in your case.

slide_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
    <translate
        android:duration="1000"
        android:fromXDelta="100%"
        android:toXDelta="0%" >
    </translate>
</set>

我发现的解决方案是使用默认动画持续时间声明一个持续时间int，而内部设置的动画中我的持续时间=持续时间+300。而且效果很好。
