循环动画可绘制 [英] Loop animation drawable

问题描述

我正在尝试为某些png设置动画，并且我会循环播放动画.这是我的代码:

I'm trying to animate some png and i would loop the animation. This is my code:

wave.setBackgroundResource(R.drawable.wave_animation);
                frameAnimation = (AnimationDrawable)wave.getBackground();
                frameAnimation.setCallback(wave);
                frameAnimation.setVisible(true, true);
                frameAnimation.start();

，这里是带有png的xml

and here the xml with the png

<animation-list xmlns:android="http://schemas.android.com/apk/res/android"  android:oneshot="true">
    <item android:drawable="@drawable/wave_01" android:duration="200" />
    <item android:drawable="@drawable/wave_02" android:duration="200" />
    <item android:drawable="@drawable/wave_03" android:duration="200" />
    <item android:drawable="@drawable/wave_04" android:duration="200" />
</animation-list>

我还添加了android:oneshot = false，但不起作用.

I added also the android:oneshot=false but doesn't work.

推荐答案

只需将android:oneshot="false"更改为这样

<animation-list xmlns:android="http://schemas.android.com/apk/res/android"  android:oneshot="false">
    <item android:drawable="@drawable/wave_01" android:duration="200" />
    <item android:drawable="@drawable/wave_02" android:duration="200" />
    <item android:drawable="@drawable/wave_03" android:duration="200" />
    <item android:drawable="@drawable/wave_04" android:duration="200" />
</animation-list>
