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"
/>
創(chuàng)建一個 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 中代碼
ImageView img = (ImageView) findViewById(R.id.iv_main);
final ObjectAnimator anim = ObjectAnimator.ofInt(img, "ImageLevel", 0, 10000);
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);
最終效果：
占位圖
水平loading動畫
替換上面使用的 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：
占位圖
