裁剪框样式

[sweet2o09]

你好,我想问下,我想修改你的裁剪框样式,你的只有4个小圆点,我想顺便画一个框把4个圆点连接起来,但是不知道要怎么画

这个功能需要修改类CropImageView draw方法中

`// 绘制黑色背景 backUpRect.set(0, 0, w, cropRect.top); backLeftRect.set(0, cropRect.top, cropRect.left, cropRect.bottom); backRightRect.set(cropRect.right, cropRect.top, w, cropRect.bottom); backDownRect.set(0, cropRect.bottom, w, h);

    canvas.drawRect(backUpRect, mBackgroundPaint);
    canvas.drawRect(backLeftRect, mBackgroundPaint);
    canvas.drawRect(backRightRect, mBackgroundPaint);
    canvas.drawRect(backDownRect, mBackgroundPaint);

    // 绘制四个控制点
    int radius = CIRCLE_WIDTH >> 1;
    leftTopCircleRect.set(cropRect.left - radius, cropRect.top - radius,
            cropRect.left + radius, cropRect.top + radius);
    rightTopCircleRect.set(cropRect.right - radius, cropRect.top - radius,
            cropRect.right + radius, cropRect.top + radius);
    leftBottomRect.set(cropRect.left - radius, cropRect.bottom - radius,
            cropRect.left + radius, cropRect.bottom + radius);
    rightBottomRect.set(cropRect.right - radius, cropRect.bottom - radius,
            cropRect.right + radius, cropRect.bottom + radius);

`

canvas.drawRect(...) 来实现
