安卓 <wbr>SeekBar与Matrix结合对图片进行旋转、斜切操作
关键代码：

Matrix matrix = new Matrix();
switch (seekBar.getId())
{
case R.id.x_seekBar:
matrix.reset();
matrix.postRotate(seekBar.getProgress()); //设置旋转
break;
case R.id.y_seekBar:
matrix.reset();
matrix.setSkew((float) (seekBar.getProgress() / 100), (float) (seekBar.getProgress() / 100)); //设置斜切
break;
}
System.gc();
bp=Bitmap.createBitmap(bitmap,0,0,w,h,matrix,true);
iv.setImageBitmap(bp);
