- How to add a shadow and a border on circular imageView android? 7 answers
I need to create an android app with having an imageview
that need to be a circle (by croping squre image). I have used some coding from StackOverFlow but I've no idea to add a border to it.
Coding below:
package com.fidenz.fexceller.fexceller;
/**

import android.graphics.Bitmap;
import android.graphics.BitmapShader;
import android.graphics.Canvas;
import android.graphics.ColorFilter;
import android.graphics.Paint;
import android.graphics.PixelFormat;
import android.graphics.Rect;
import android.graphics.RectF;
import android.graphics.Shader;
import android.graphics.drawable.Drawable;
public class RoundedImg extends Drawable {
private final Bitmap mBitmap;
private final Paint mPaint;
private final RectF mRectF;
private final int mBitmapWidth;
private final int mBitmapHeight;
public RoundedImg(Bitmap bitmap) {
mBitmap = bitmap;
mRectF = new RectF();
mPaint = new Paint();
mPaint.setAntiAlias(true);
mPaint.setDither(true);
final BitmapShader shader = new BitmapShader(bitmap, Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
mPaint.setShader(shader);
mBitmapWidth = mBitmap.getWidth();
mBitmapHeight = mBitmap.getHeight();
}
@Override
public void draw(Canvas canvas) {
canvas.drawOval(mRectF, mPaint);
}
@Override
protected void onBoundsChange(Rect bounds) {
super.onBoundsChange(bounds);
mRectF.set(bounds);
}
@Override
public void setAlpha(int alpha) {
if (mPaint.getAlpha() != alpha) {
mPaint.setAlpha(alpha);
invalidateSelf();
}
}
@Override
public void setColorFilter(ColorFilter cf) {
mPaint.setColorFilter(cf);
}
@Override
public int getOpacity() {
return PixelFormat.TRANSLUCENT;
}
@Override
public int getIntrinsicWidth() {
return mBitmapWidth;
}
@Override
public int getIntrinsicHeight() {
return mBitmapHeight;
}
public void setAntiAlias(boolean aa) {
mPaint.setAntiAlias(aa);
invalidateSelf();
}
@Override
public void setFilterBitmap(boolean filter) {
mPaint.setFilterBitmap(filter);
invalidateSelf();
}
@Override
public void setDither(boolean dither) {
mPaint.setDither(dither);
invalidateSelf();
}
public Bitmap getBitmap() {
return mBitmap;
}
}
And I call image using this:
ImageView profilePic;
RoundedImg roundedImage,ring;
profilePic = (ImageView)findViewById(R.id.img_home_profile_pic);
Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.no_image);
roundedImage = new RoundedImg(bm);
profilePic.setImageDrawable(roundedImage);
