布局

 <RelativeLayout            android:layout_width="match_parent"            android:layout_height="match_parent">            <com.finance.geex253.geexfinance.view.RoundOfHeadImageView                android:id="@+id/imageUpLoadItemImg"                android:layout_width="match_parent"                android:layout_height="match_parent"                android:scaleType="fitXY"                android:layout_alignParentBottom="true"/>        </RelativeLayout>

自定义view

public class RoundOfHeadImageView extends ImageView {    public RoundOfHeadImageView(Context context, AttributeSet attrs) {        super(context, attrs);        init();    }    public RoundOfHeadImageView(Context context) {        super(context);        init();    }    private final RectF roundRect  = new RectF();    private       float rect_adius = 4;//此时是矩形框，50为圆形框，自行修改    private final Paint maskPaint  = new Paint();    private final Paint zonePaint  = new Paint();    private void init() {        maskPaint.setAntiAlias(true);        maskPaint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));        //        zonePaint.setAntiAlias(true);        //zonePaint.setColor(Color.WHITE);        zonePaint.setColor(Color.parseColor("#D7D7D7"));        float density = getResources().getDisplayMetrics().density;        rect_adius = rect_adius * density;    }    public void setRectAdius(float adius) {        rect_adius = adius;        invalidate();    }    @Override    protected void onLayout(boolean changed, int left, int top, int right,                            int bottom) {        super.onLayout(changed, left, top, right, bottom);        int w = getWidth();        int h = getHeight();        roundRect.set(0, 0, w, h);    }    @Override    public void draw(Canvas canvas) {        canvas.saveLayer(roundRect, zonePaint, Canvas.ALL_SAVE_FLAG);        canvas.drawRoundRect(roundRect, rect_adius, rect_adius, zonePaint);        //        canvas.saveLayer(roundRect, maskPaint, Canvas.ALL_SAVE_FLAG);        super.draw(canvas);        canvas.restore();    }}
