The following are instructions:
Pasting the above code directly will cause problems, because of the lack of a custom class - AImageViewRoundOval.java, the code I have already put in the previous article. https://my.oschina.net/u/3724795/blog/1583883
Let's talk about the onActivityResult method. The bundle method is used here to compress the captured image, but I found at runtime that if the following code is used directly, the image will be reduced and ugly.
/**
* 返回应用时回调方法
*/
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == REQUEST_THUMBNAIL) {//对应第一种方法
/**
* 通过这种方法取出的拍摄会默认压缩，因为如果相机的像素比较高，拍摄出来的图会比较高清，
* 如果图太大会造成内存溢出（OOM），因此此种方法会默认给图片尽心压缩
*/
Bundle bundle = data.getExtras();
Bitmap bmp = (Bitmap) bundle.get("data");
((ImageView) findViewById(R.id.roundRect3)).setImageBitmap(bmp);// 将图片显示在ImageView里
}
}
｝So I redefine the size of the ImageView and enlarge the image to the original size (I also found that the loophole in this code is that if the camera is using proactive, even if I redefine the size, it is useless, it is still so small ), in fact, the magnification ratio can be adjusted according to your own needs. In fact, if you master this code, you can make a form that zooms in and out of the picture.
/* 设置图片放大的比例 */
double scale = 4;
/* 计算这次要放大的比例 */
scaleWidth = (float) (scaleWidth * scale);
scaleHeight = (float) (scaleHeight * scale);
