本站于2023年9月4日。收到“大连君*****咨询有限公司”通知
说我们IIS7站长博客，有一篇博文用了他们的图片。
要求我们给他们一张图片6000元。要不然法院告我们
为避免不必要的麻烦，IIS7站长博客，全站内容图片下架、并积极应诉
博文内容全部不再显示，请需要相关资讯的站长朋友到必应搜索。谢谢！
另祝：版权碰瓷诈骗团伙，早日弃暗投明。
相关新闻：借版权之名、行诈骗之实，周某因犯诈骗罪被判处有期徒刑十一年六个月
叹！百花齐放的时代,渐行渐远!
本文实例为大家分享了Android实现上传图片功能的具体代码，供大家参考，具体内容如下
设定拍照返回的图片路径
/**
* 设定拍照返回的图片路径
* @param image 图片路径
* @param i 约定值
*/
protected void image(String image, int i) {
//创建file对象，用于存储拍照后的图片，这也是拍照成功后的照片路径
outputImage = new File(getExternalCacheDir(),image);
try {
//判断文件是否存在，存在删除，不存在创建
if (outputImage.exists()){
outputImage.delete();
}
outputImage.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
//相机拍照返回图片路径
Uri photoUri;
//判断当前Android版本
if(Build.VERSION.SDK_INT>=24){
photoUri = FileProvider.getUriForFile(TextActivity.this,"包名.FileProvider",outputImage);
}else {
photoUri = Uri.fromFile(outputImage);
}
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, photoUri);
startActivityForResult(intent, i);
}

调用系统相机拍照接受返回的图片路径
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == IMAGE_Y) {
getImageView(binding.imageY,"0");
}
if (requestCode == IMAGE_Q) {
getImageView(binding.imageQ,"1");
