边框画不完整 #1
Description
当没有margin的时候你的边框会出现问题
这样画就可以了
private void drawBorder(Canvas canvas){
if(borderWidth > 0){
borderPath.reset();
final int width = getWidth();
final int height = getHeight();
if (shapeType == 0) {
final float halfBorderWidth = borderWidth * 0.5f;
final float cx = width * 0.5f;
final float cy = height * 0.5f;
final float radius = Math.min(width, height) * 0.5f;
borderPath.addCircle(cx, cy, radius - halfBorderWidth, Path.Direction.CW);
} else {// 当ShapeType = 1 时 图片为圆角矩形
final float halfBorderWidth = borderWidth * 0.35f;//乘以0.5会导致border在圆角处不能包裹原图
// leftTopRadius = Math.min(leftTopRadius, Math.min(width, height) * 0.5f);
// leftBottomRadius = Math.min(leftBottomRadius, Math.min(width, height) * 0.5f);
// rightTopRadius = Math.min(rightTopRadius, Math.min(width, height) * 0.5f);
// rightBottomRadius = Math.min(rightBottomRadius, Math.min(width, height) * 0.5f);
RectF rect = new RectF(halfBorderWidth, halfBorderWidth, width - halfBorderWidth, height - halfBorderWidth);
borderPath.addRoundRect(rect,
new float[]{radius, radius, radius, radius,
radius, radius, radius, radius},
Path.Direction.CW);
}
Paint paint = new Paint();
paint.setStrokeWidth(borderWidth);
paint.setStyle(Paint.Style.STROKE);
paint.setColor(borderColor);
paint.setAntiAlias(true);
canvas.drawPath(borderPath, paint);
}
}
