直接从URL到应用程序布局显示动画GIF的简单方法是使用WebView类。

步骤1: 在XML布局中

< WebView android: id =“@ + id / webView” android: layout_width = " 50 dp” android: layout_height = " 50 dp” />

第二步:在活动中

网络视图 wb; wb = （WebView） findViewById（R.id.webView）; wb.loadUrl（“https://.......）;

步骤3:在Manifest.XML中设置Internet权限

< uses-permission android: name = " android.permission。互联网" / >

步骤4:如果你想让你的GIF背景透明，让GIF适合你的布局

wb.setBackgroundColor (Color.TRANSPARENT); wb.getSettings () .setLoadWithOverviewMode(真正的); wb.getSettings () .setUseWideViewPort(真正的);

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);

    }

}

最简单的方法-可以考虑下面的代码

我们可以利用Imageview的setImageResource，参考下面的代码相同。

下面的代码可以用来显示像gif一样的图像，如果你有gif的多次分割图像。只需从在线工具中将gif分割成单独的png，并按照以下顺序将图像放入可绘制图中

Image_1.png, image_2.png等等。

让处理程序动态地更改图像。

int imagePosition = 1;
    Handler handler = new Handler();
        Runnable runnable = new Runnable() {
            public void run() {
                updateImage();
            }
        };




    public void updateImage() {

                appInstance.runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        int resId = getResources().getIdentifier("image_" + imagePosition, "drawable", appInstance.getPackageName());
                        gifImageViewDummy.setImageResource(resId);
                        imagePosition++;
    //Consider you have 30 image for the anim
                        if (imagePosition == 30) {
//this make animation play only once
                            handler.removeCallbacks(runnable);

                        } else {
    //You can define your own time based on the animation
                            handler.postDelayed(runnable, 50);
                        }

//to make animation to continue use below code and remove above if else
// if (imagePosition == 30)
//imagePosition = 1;
// handler.postDelayed(runnable, 50);
// 
                    }
                });
              }

首先，Android浏览器应该支持动画gif。如果没有，那就是bug!看一下问题跟踪器。

如果你在浏览器外显示这些动画gif，情况可能就不一样了。要做到你所要求的，将需要外部库，支持动画gif解码。

第一个接口是Java2D或JAI (Java Advanced Imaging) API，如果Android Dalvik在你的应用程序中支持这些库，我会感到非常惊讶。

用壁画。以下是如何做到这一点:
