android 加载 .gif 并一直刷新

1.
dependencies {
compile ‘pl.droidsonroids.gif:android-gif-drawable:1.2.+’
}

2.
< pl.droidsonroids.gif.GifImageView
android:layout_width=”match_parent”
android:layout_height=”match_parent”
android:background=”@drawable/gif_file”
/>

3.如果不gif文件播放了一次就不播放了

private void gifLoop(){        GifImageView  gifImageView = (GifImageView) findViewById(R.id.gif_bg);        GifDrawable gifDrawable = null;        try {            gifDrawable = new GifDrawable(getResources(), R.drawable.login_bg);            gifDrawable.setLoopCount(0);        } catch (IOException e) {            e.printStackTrace();        }        gifImageView.setImageDrawable(gifDrawable);    }
