完整的例子

布局

ImageView

<ImageView    android:id="@+id/iv_main"    android:layout_width="100dp"    android:layout_height="100dp"    android:layout_alignParentBottom="true"    android:scaleType="fitXY"    />

创建一个 drawable

R.drawable.rotate_pro

<?xml version="1.0" encoding="utf-8"?><rotate    xmlns:android="http://schemas.android.com/apk/res/android"    android:drawable="@drawable/group_1"    android:fromDegrees="0"    android:pivotX="50%"    android:pivotY="50%"    android:toDegrees="360"/>

Activity 中代码

ImageView img = (ImageView) findViewById(R.id.iv_main);final ObjectAnimator anim = ObjectAnimator.ofInt(img, "ImageLevel", 0, MAX_LEVEL);anim.setDuration(800);anim.setRepeatCount(ObjectAnimator.INFINITE);anim.start();Glide.with(this)        .load(path)        .placeholder(R.drawable.rotate_pro)        .crossFade()        .listener(new RequestListener<String, GlideDrawable>() {            @Override            public boolean onException(Exception e, String model, Target<GlideDrawable> target, boolean isFirstResource) {                anim.cancel();                Log.d(TAG, "onException: ");                return false;            }            @Override            public boolean onResourceReady(GlideDrawable resource, String model, Target<GlideDrawable> target, boolean isFromMemoryCache, boolean isFirstResource) {                anim.cancel();                Log.d(TAG, "onResourceReady: ");                return false;            }        })        .into(img);

最终效果：

占位图

水平loading动画

替换上面使用的 drawable 即可

<?xml version="1.0" encoding="utf-8"?><layer-list xmlns:android="http://schemas.android.com/apk/res/android">    <item>        <clip            android:clipOrientation="horizontal"            android:drawable="@drawable/rectangle"            >        </clip>    </item></layer-list>

效果：
