Question

我想从使用此方法的Google Play游戏中获取个人资料图片：

public void loadPlayerImage() {
            ImageView playerImage=(ImageView) findViewById(R.id.playerImage);
            Player me = Games.Players.getCurrentPlayer(mGoogleApiClient);
            ImageManager mgr = ImageManager.create(this);
            mgr.loadImage(playerImage, me.getIconImageUri());
}

但是当我尝试用这个库圈出它时它没有显示图像： https://github.com/hdodenhof/CircleImageView

如何圈出个人资料图片？

您可以将此code用作ImageHelper类中的帮助程序，并将其扩展为传递给定图像所需的羽化量。

public static Bitmap getRoundedCornerBitmap(Bitmap bitmap) {
  Bitmap output = Bitmap.createBitmap(bitmap.getWidth(),
      bitmap.getHeight(), Config.ARGB_8888);
  Canvas canvas = new Canvas(output);

  final int color = 0xff424242;
  final Paint paint = new Paint();
  final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
  final RectF rectF = new RectF(rect);
  final float roundPx = 12;

  paint.setAntiAlias(true);
  canvas.drawARGB(0, 0, 0, 0);
  paint.setColor(color);
  canvas.drawRoundRect(rectF, roundPx, roundPx, paint);

  paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
  canvas.drawBitmap(bitmap, rect, rect, paint);

  return output;
}

我也需要一个圆形的ImageView，我使用下面的代码，你可以相应地修改它：

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Bitmap.Config;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.PorterDuff.Mode;
import android.graphics.PorterDuffXfermode;
import android.graphics.Rect;
import android.graphics.drawable.BitmapDrawable;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;

public class RoundedImageView extends ImageView {

  public RoundedImageView(Context context) {
      super(context);
  }

  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();
      @SuppressWarnings("unused")
      int 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) {
          float smallest = Math.min(bmp.getWidth(), bmp.getHeight());
          float factor = smallest / radius;
          sbmp = Bitmap.createScaledBitmap(bmp,
                  (int) (bmp.getWidth() / factor),
                  (int) (bmp.getHeight() / factor), false);
      } else {
          sbmp = bmp;
      }

      Bitmap output = Bitmap.createBitmap(radius, radius, Config.ARGB_8888);
      Canvas canvas = new Canvas(output);

      final String color = "#BAB399";
      final Paint paint = new Paint();
      final Rect rect = new Rect(0, 0, radius, radius);

      paint.setAntiAlias(true);
      paint.setFilterBitmap(true);
      paint.setDither(true);
      canvas.drawARGB(0, 0, 0, 0);
      paint.setColor(Color.parseColor(color));
      canvas.drawCircle(radius / 2 + 0.7f, radius / 2 + 0.7f,
              radius / 2 + 0.1f, paint);
      paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
      canvas.drawBitmap(sbmp, rect, rect, paint);

      return output;
  }

}
