問題：在glide配置中使用options.transforms(new GlideRoundedCornersTransform(context,5));來實(shí)現(xiàn)圓角以及centerCrop效果時(shí)，刷新界面會(huì)出現(xiàn)閃爍
解決方法：由于glide默認(rèn)采用了centerCrop方式顯示圖片，所以基本不需要再次設(shè)置，而圓角采用自定義控件的方式就可以實(shí)現(xiàn)其效果并不會(huì)出現(xiàn)閃爍問題

當(dāng)然如果不介意可以使用下面方法：

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);}@Overrideprotected 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);}@Overridepublic void updateDiskCacheKey(MessageDigest messageDigest) {} }
