Java 如何在android中使用毕加索的RoundeMageView

我想在RoundeImage视图中加载毕加索库中的图像

This is the procedure, what i followed for one of my project. Please, have a look. It may lead you to find the solution as per your requirement.

Create a class `RoundedTransform` and paste this code.

import android.graphics.Bitmap;
import android.graphics.BitmapShader;
import android.graphics.Canvas;
import android.graphics.Paint;

import com.squareup.picasso.Transformation;

public class RoundedTransform implements Transformation {
@Override
public Bitmap transform(Bitmap source) {
int size = Math.min(source.getWidth(), source.getHeight());

int x = (source.getWidth() - size) / 2;
int y = (source.getHeight() - size) / 2;

Bitmap squaredBitmap = Bitmap.createBitmap(source, x, y, size, size);
if (squaredBitmap != source) {
source.recycle();
}

Bitmap bitmap = Bitmap.createBitmap(size, size, source.getConfig());

Canvas canvas = new Canvas(bitmap);
Paint paint = new Paint();
BitmapShader shader = new BitmapShader(squaredBitmap,
BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP);
paint.setShader(shader);
paint.setAntiAlias(true);

float r = size / 2f;
canvas.drawCircle(r, r, r, paint);

squaredBitmap.recycle();
return bitmap;
}

@Override
public String key() {
return "circle";
}
}


Then while calling the image view in your Activity,call as follows 

        iv = (ImageView)rootView.findViewById(R.id.imageView1);
        String imageUrl = "image";
        String url = "Pass your url";   
            if(url!=null){                              
                imageUrl = url;
            }

            Picasso.with(getApplicationContext()).load(imageUrl).fit().centerCrop().transform(new RoundedTransform()).placeholder(R.drawable.ic_launcher).error(R.drawable.ic_launcher).into((ImageView)findViewById(R.id.imageView1));

我在引用

我真的无法理解如何使用RoundeMageView

你能告诉我怎么用吗我不懂怎么用

当我设置布局时

<com.makeramen.RoundedImageView
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/imageView1"
        android:src="@drawable/photo1"
        android:scaleType="centerCrop"
        app:corner_radius="30dip"
        app:border_width="2dip"
        app:border_color="#333333"
        app:mutate_background="true"
        app:oval="true" />

如果我使用这样的给定错误..无法解决RoundeMageView

尝试使用可用的库尝试使用

                imageUrl = url;
            }

            Picasso.with(getApplicationContext()).load(imageUrl).fit().centerCrop().transform(new RoundedTransform()).placeholder(R.drawable.ic_launcher).error(R.drawable.ic_launcher).into((ImageView)findViewById(R.id.imageView1));

对于android中的圆形图像视图，首先尝试创建一个基本视图。在这里，我找到了一篇关于在facebook messanger中创建roundImageview的文章，为毕加索做了一个转变

Transformation transformation = new RoundedTransformationBuilder()
          .borderColor(Color.BLACK)
          .borderWidthDp(3)
          .cornerRadiusDp(30)
          .oval(false)
          .build();

Picasso.with(context)
    .load(url)
    .fit()
    .transform(transformation)
    .into(imageView);

将其编辑为：

app:riv_corner_radius="30dip"

app:riv_border_width="2dip"

@Prag'sシ 我发布了我的布局部分…我用它代替ImageView givign错误找不到资源…您的java代码亲爱的..更新了..@Prag'sシ 这是另一个供您尝试和实施的方法
