這些其實(shí)很簡(jiǎn)單，在項(xiàng)目里調(diào)用這兩個(gè)代碼就行了。但是圓角圖片還是有點(diǎn)小坑（有的圖片設(shè)置過后不是圓角圖片，可能是每個(gè)人上傳的圖片尺寸長(zhǎng)寬比例不是合適的值），不過我已經(jīng)解決了。下面就來看看怎么用的吧
先上一個(gè)效果圖：
首先要下載glide jar包
下載鏈接：glide jia包? 密碼：pk8n
1.圓角圖片
import android.content.Context;
import android.content.res.Resources;
import android.graphics.Bitmap;
import android.graphics.BitmapShader;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.graphics.RectF;
import com.bumptech.glide.load.engine.bitmap_recycle.BitmapPool;
import com.bumptech.glide.load.resource.bitmap.BitmapTransformation;
/**

*/
public classGlideRoundTransformextendsBitmapTransformation {
private static floatradius=0f;
publicGlideRoundTransform(Context context) {
this(context,4);
}
publicGlideRoundTransform(Context context, intdp) {
super(context);
this.radius= Resources.getSystem().getDisplayMetrics().density* dp;
}
@Override
protected Bitmaptransform(BitmapPool pool,Bitmap toTransform, intoutWidth, intoutHeight) {
returnroundCrop(pool,toTransform);
}
private staticBitmaproundCrop(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 =newCanvas(result);
Paint paint =newPaint();
paint.setShader(newBitmapShader(source,BitmapShader.TileMode.CLAMP,BitmapShader.TileMode.CLAMP));
paint.setAntiAlias(true);
RectF rectF =newRectF(0f,0f,source.getWidth(),source.getHeight());
//設(shè)置圓角弧度
canvas.drawRoundRect(rectF,radius,radius,paint);
returnresult;
}
@Override
public StringgetId() {
returngetClass().getName() + Math.round(radius);
}
}
這是我的使用，我就不過多解釋（10就是你要設(shè)置圓角弧度的度數(shù)），如果你要使用，請(qǐng)改成你想要的。
2.圓形圖片
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapShader;
import android.graphics.Canvas;
import android.graphics.Paint;
import com.bumptech.glide.load.engine.bitmap_recycle.BitmapPool;
import com.bumptech.glide.load.resource.bitmap.BitmapTransformation;
/**
* Created by tongshoujun on 2017/9/12.
* 圓形圖
*/
public class GlideCircleTransformextendsBitmapTransformation {
public GlideCircleTransform(Context context) {
super(context);
}
@Override
protected Bitmaptransform(BitmapPool pool,Bitmap toTransform, intoutWidth, intoutHeight) {
returncircleCrop(pool,toTransform);
}
private static BitmapcircleCrop(BitmapPool pool,Bitmap source) {
if(source ==null)return null;
intsize = Math.min(source.getWidth(),source.getHeight());
intx = (source.getWidth() - size) /2;
inty = (source.getHeight() - size) /2;
//TODO this could be acquired from the pool too
Bitmap squared = Bitmap.createBitmap(source,x,y,size,size);
Bitmap result = pool.get(size,size,Bitmap.Config.ARGB_8888);
if(result ==null) {
result = Bitmap.createBitmap(size,size,Bitmap.Config.ARGB_8888);
}
Canvas canvas =newCanvas(result);
Paint paint =newPaint();
paint.setShader(newBitmapShader(squared,BitmapShader.TileMode.CLAMP,BitmapShader.TileMode.CLAMP));
paint.setAntiAlias(true);
floatr = size /2f;
canvas.drawCircle(r,r,r,paint);
returnresult;
}
@Override
public StringgetId() {
returngetClass().getName();
}
}
使用結(jié)果：
