比较简单的办法,效果比较丑陋,同理,你可以用阴影图片替代画线得到好的效果 重写ImageView public class HKImageView extends ImageView { public HKImageView(Context context, AttributeSet attrs) { super(context, attrs, 0); } public HKImageView(Context context) { super(context); } @Override protected void onDraw(Canvas canvas) { Log.d("lg", "onDraw"); super.onDraw(canvas); // 画边框 Rect rect1 = getRect(canvas); Paint paint = new Paint(); paint.setColor(Color.GRAY); paint.setStyle(Paint.Style.STROKE); // 画边框 canvas.drawRect(rect1, paint); paint.setColor(Color.LTGRAY); // 画一条竖线,模拟右边的阴影 canvas.drawLine(rect1.right + 1, rect1.top + 2, rect1.right + 1, rect1.bottom + 2, paint); // 画一条横线,模拟下边的阴影 canvas.drawLine(rect1.left + 2, rect1.bottom + 1, rect1.right + 2, rect1.bottom + 1, paint); // 画一条竖线,模拟右边的阴影 canvas.drawLine(rect1.right + 2, rect1.top + 3, rect1.right + 2, rect1.bottom + 3, paint); // 画一条横线,模拟下边的阴影 canvas.drawLine(rect1.left + 3, rect1.bottom + 2, rect1.right + 3, rect1.bottom + 2, paint); } Rect getRect(Canvas canvas) { Rect rect = canvas.getClipBounds(); rect.bottom -= getPaddingBottom(); rect.right -= getPaddingRight(); rect.left += getPaddingLeft(); rect.top += getPaddingTop(); return rect; } } 使用 要给图片添加padding才有效果 imageView.setPadding(3, 3, 5, 5);
