Tutorial rounded picture of you as shown below

First you create 1 CricleImage class inherits from the ImageView as follows:

package cachhoc.net.democircleimageview;

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 CircleImage extends ImageView {

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

	public CircleImage(Context context, AttributeSet attrs) {
		super(context, attrs);
	}

	public CircleImage(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();

		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 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;
	}

}

Then you enter the interface design activity_main.xml file as follows:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center_horizontal"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="5dp"
        android:layout_marginTop="30dp"
        android:text="@string/avata"
        android:textAppearance="?android:attr/textAppearanceLarge" />

    <cachhoc.net.democircleimageview.CircleImage
        android:id="@+id/img"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/nguyenvanquan7826" />

</LinearLayout>

In it you to the card cachhoc.net.democircleimageview.CircleImage is a package containing the file path created above CricleImage.java.

Vậy là chúng ta được giao diện như đầu bài viết rồi 😉
