注意事项：
1.设置一些配置的时候尽量使用
final RequestOptions options = new RequestOptions();
options.skipMemoryCache(false);
options.diskCacheStrategy(DiskCacheStrategy.ALL);
options.priority(Priority.HIGH);
options.error(R.mipmap.home_img_loading_pic1);
options.placeholder(R.mipmap.home_img_loading_pic1);
但是在调用的使用一定要认清调用apply(options)方法。如果在使用的时候图片没有显示连设置的各种占位图都没有，很大可能就是调用的方法出错，因为之前版本的方法不一样。(我自己经历的血的教训)

问题：在glide配置中使用options.transforms(new GlideRoundedCornersTransform(context,5));来实现圆角以及centerCrop效果时，刷新界面会出现闪烁
解决方法：由于glide默认采用了centerCrop方式显示图片，所以基本不需要再次设置，而圆角采用自定义控件的方式就可以实现其效果并不会出现闪烁问题
public class GlideRoundTransform extends CenterCrop {
private static float radius = 10f;
public GlideRoundTransform(Context context) {
this(context, 10);
}
public GlideRoundTransform(Context context, int dp) {
super();
this.radius = UnitConversionUtil.dip2px(context, dp);
}
@Override
protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {
//glide4.0+
Bitmap transform = super.transform(pool, toTransform, outWidth, outHeight);
return roundCrop(pool, transform);
//glide3.0
//return roundCrop(pool, toTransform);
}
private static Bitmap roundCrop(BitmapPool pool, Bitmap source) {
if (source == null) return null;
Bitmap result = pool.get(source.getWidth(), source.getHeight(), Bitmap.Config.ARGB_8888);
if (result == null) {
result = Bitmap.createBitmap(source.getWidth(), source.getHeight(), Bitmap.Config.ARGB_8888);
}
Canvas canvas = new Canvas(result);
Paint paint = new Paint();
paint.setShader(new BitmapShader(source, BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP));
paint.setAntiAlias(true);
RectF rectF = new RectF(0f, 0f, source.getWidth(), source.getHeight());
canvas.drawRoundRect(rectF, radius, radius, paint);
return result;
}
public String getId() {
return getClass().getName() + Math.round(radius);
}
@Override
public void updateDiskCacheKey(MessageDigest messageDigest) {
}
}
