试试这个，下面的代码在进度条中显示gif文件

loading_activity.xml(在布局文件夹中)

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#ffffff" >

    <ProgressBar
        android:id="@+id/progressBar"
        style="?android:attr/progressBarStyleLarge"
        android:layout_width="70dp"
        android:layout_height="70dp"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:indeterminate="true"
        android:indeterminateDrawable="@drawable/custom_loading"
        android:visibility="gone" />

</RelativeLayout>

Custom_loading.xml(在可绘制文件夹中)

这里我把black_gif.gif(在可绘制文件夹)，你可以把自己的GIF在这里

<?xml version="1.0" encoding="utf-8"?>
<animated-rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:drawable="@drawable/black_gif"
    android:pivotX="50%"
    android:pivotY="50%" />

java(在res文件夹中)

public class LoadingActivity extends Activity {

    ProgressBar bar;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_loading);
        bar = (ProgressBar) findViewById(R.id.progressBar);
        bar.setVisibility(View.VISIBLE);

    }

}

如果你想使用Glide加载gif:

Glide.with(this)
        .asGif()
        .load(R.raw.onboarding_layers) //Your gif resource
        .apply(RequestOptions.diskCacheStrategyOf(DiskCacheStrategy.NONE))
        .listener(new RequestListener<GifDrawable>() {
            @Override
            public boolean onLoadFailed(@Nullable @org.jetbrains.annotations.Nullable GlideException e, Object model, Target<GifDrawable> target, boolean isFirstResource) {
                return false;
            }

            @Override
            public boolean onResourceReady(GifDrawable resource, Object model, Target<GifDrawable> target, DataSource dataSource, boolean isFirstResource) {
                resource.setLoopCount(1);
                return false;
            }
        })
        .into((ImageView) view.findViewById(R.id.layer_icons));

为了节省资源，有滑翔库。 不知道为什么要使用其他任何东西，特别是webview只显示图像。 Glide是一个完美而简单的库，它可以从gif中准备动画，并将其直接放到imageview中。 gifdrawable句柄动画本身的逻辑。 Gif有lzw压缩原始rgb数据的动画里面。 没有理由复杂的使用webview和管理更多的文件，只显示一个gif文件在应用程序。

把它放到WebView中，它必须能够正确地显示它，因为默认浏览器支持gif文件。(Froyo+，如果我没记错的话)

这是我为在应用程序中显示动图所做的。我扩展了ImageView，这样人们就可以自由地使用它的属性。它可以显示gif从url或资产目录。 这个库还使扩展类从它继承和扩展它来支持不同的方法来初始化gif变得很容易。

https://github.com/Gavras/GIFView

在github页面上有一个小指南。

它也发布在Android Arsenal上:

https://android-arsenal.com/details/1/4947

使用的例子:

从XML:

<com.whygraphics.gifview.gif.GIFView xmlns:gif_view="http://schemas.android.com/apk/res-auto"
        android:id="@+id/main_activity_gif_vie"
        android:layout_width="200dp"
        android:layout_height="200dp"
        android:scaleType="center"
        gif_view:gif_src="url:http://pop.h-cdn.co/assets/16/33/480x264/gallery-1471381857-gif-season-2.gif" />

活动中:

    GIFView mGifView = (GIFView) findViewById(R.id.main_activity_gif_vie);

    mGifView.setOnSettingGifListener(new GIFView.OnSettingGifListener() {
                @Override
                public void onSuccess(GIFView view, Exception e) {
                    Toast.makeText(MainActivity.this, "onSuccess()", Toast.LENGTH_SHORT).show();
                }

                @Override
                public void onFailure(GIFView view, Exception e) {

        }
});

以编程方式设置gif:

mGifView.setGifResource("asset:gif1");
