将picasso库与圆形图像视图结合使用
将picasso库与圆形图像视图结合使用
提问于 2015-06-05 18:27:39
我正在考虑使用毕加索的库从URL下载图像并将其传递到圆形图像视图中，但是由于毕加索要求您传入一个实际的imageView，因此我在如何做到这一点上停滞不前
我在这里使用的是毕加索图库http://square.github.io/picasso/，在这里使用的是圆形图像视图类https://github.com/hdodenhof/CircleImageView
下面是获取图像的代码的开始部分
private void getData() {
userName.setText(prefs.getString("userName",""));
jobTitle.setText(prefs.getString("profile",""));
userLocation.setText(prefs.getString("location",""));
// ??????
// Picasso.with(context).load(image link here).into(imageview here);
//CircleImageView img = new CircleImageView(this);
//img.setImageResource();
//img.setImageBitmap();
//img.setImageDrawable();
//img.setImageURI();
}编辑：
下面是circleImageView的xml
<michael.CircleImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:src="@drawable/shadow"
android:layout_gravity="center"
android:layout_marginTop="16dp"
app:border_width="2dp"
app:border_color="#274978"
android:id="@+id/circleImageView"回答 5

使用这个
活动类
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String imageUrl = "https://www.baby-connect.com/images/baby2.gif";
CircleImageView imageView = (CircleImageView) findViewById(R.id.image);
Picasso.with(getApplicationContext()).load(imageUrl)
.placeholder(R.drawable.images).error(R.drawable.ic_launcher)
.into(imageView);
}
}布局文件
<de.hdodenhof.circleimageview.CircleImageView
android:id="@+id/image"
android:layout_width="160dp"
android:layout_height="160dp"
android:layout_centerInParent="true"
android:src="@drawable/images"
app:border_color="#ffffff"
app:border_width="2dp" />这工作得很好。

我不认为你需要CircleImageView库
你可以实现循环变换，检查下面的要点
https://gist.github.com/julianshen/5829333
然后
Picasso.with(activity).load(image link here)
.transform(new CircleTransform()).into(ImageView);Stack Overflow用户

使用此代码创建循环Imageview ...
public class RoundedImageView extends ImageView {
public RoundedImageView(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
public RoundedImageView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public RoundedImageView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
protected void onDraw(Canvas canvas) {
Drawable drawable = getDrawable();
if (drawable == null) {
return;
}
if (getWidth() == 0 || getHeight() == 0) {
return;
}
Bitmap b = ((BitmapDrawable)drawable).getBitmap() ;
Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);
int w = getWidth(), h = getHeight();
Bitmap roundBitmap = getCroppedBitmap(bitmap, w);
canvas.drawBitmap(roundBitmap, 0,0, null);
}
public static Bitmap getCroppedBitmap(Bitmap bmp, int radius) {
Bitmap sbmp;
if(bmp.getWidth() != radius || bmp.getHeight() != radius)
sbmp = Bitmap.createScaledBitmap(bmp, radius, radius, false);
else
sbmp = bmp;
Bitmap output = Bitmap.createBitmap(sbmp.getWidth(),
sbmp.getHeight(), Config.ARGB_8888);
Canvas canvas = new Canvas(output);
final int color = 0xffa19774;
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, sbmp.getWidth(), sbmp.getHeight());
paint.setAntiAlias(true);
paint.setFilterBitmap(true);
paint.setDither(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(Color.parseColor("#BAB399"));
canvas.drawCircle(sbmp.getWidth() / 2+0.7f, sbmp.getHeight() / 2+0.7f,
sbmp.getWidth() / 2+0.1f, paint);
paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
canvas.drawBitmap(sbmp, rect, rect, paint);
return output;
}
