Android AnimationDrawable 启动，完成后挂在第一帧

我试图让我的 Android 应用程序上的 AnimationDrawable 重复。我将 android:oneshot 配置为 false。（尝试使用java和XML）尽管如此，每当播放动画时，一旦完成，它就会返回到第一帧，并停止

这是我的 XML 文件

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/network_scanning" android:oneshot="false">  
<item android:drawable="@drawable/network_wireless_0" android:duration="300" />
<item android:drawable="@drawable/network_wireless_1" android:duration="300" />
<item android:drawable="@drawable/network_wireless_2" android:duration="300" />
<item android:drawable="@drawable/network_wireless_3" android:duration="300" />
<item android:drawable="@drawable/network_wireless_4" android:duration="300" />
</animation-list>

这是启动动画的代码：

@Override
public void onWindowFocusChanged(boolean hasFocus)
{
    super.onWindowFocusChanged(hasFocus);

    LinearLayout network = (LinearLayout) findViewById(R.id.wifi_anim);
    AnimationDrawable anim = (AnimationDrawable) network.getBackground();
    if (hasFocus)
    {
        anim.setOneShot(false);
        anim.setCallback(network);
        anim.setVisible(true, true);
        anim.start();
    }

}

原文

I'm trying to get the AnimationDrawable on my Android app to repeat.
I configured the android:oneshot on false. (tried both with java and with XML)
Still, whenever the animation is played, once it's done, it goes back to the first frame, and stops

This is my XML file

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/network_scanning" android:oneshot="false">  
<item android:drawable="@drawable/network_wireless_0" android:duration="300" />
<item android:drawable="@drawable/network_wireless_1" android:duration="300" />
<item android:drawable="@drawable/network_wireless_2" android:duration="300" />
<item android:drawable="@drawable/network_wireless_3" android:duration="300" />
<item android:drawable="@drawable/network_wireless_4" android:duration="300" />
</animation-list>

and this is the code to start the animation:

@Override
public void onWindowFocusChanged(boolean hasFocus)
{
    super.onWindowFocusChanged(hasFocus);

    LinearLayout network = (LinearLayout) findViewById(R.id.wifi_anim);
    AnimationDrawable anim = (AnimationDrawable) network.getBackground();
    if (hasFocus)
    {
        anim.setOneShot(false);
        anim.setCallback(network);
        anim.setVisible(true, true);
        anim.start();
    }

}
