TextView 的文字大小动画 [英] animation of TextView's text size

问题描述

我希望能够制作文本动画并更改 TextView 中文本的大小.我读到 android 中有属性动画，但如果有人知道可以为我执行此操作的简单代码或某个地方的示例，我将非常感激.提前谢谢你！

推荐答案

scale.xml

<?xml version="1.0" encoding="utf-8"?>
<set
    xmlns:android="http://schemas.android.com/apk/res/android">
    <scale
          android:fromXScale="1.0"
          android:fromYScale="1.0"
          android:toXScale="2.0"
          android:toYScale="2.0"
          android:duration="3000"></scale>
</set>

一个函数变成一个Activity:

A function into an Activity:

private void RunAnimation() 
{
    Animation a = AnimationUtils.loadAnimation(this, R.anim.scale);
    a.reset();
    TextView tv = (TextView) findViewById(R.id.firstTextView);
    tv.clearAnimation();
    tv.startAnimation(a);
}
