android拍照保存到系统相册,Android 拍照后保存到手机里，在相册找不到

1、拍完照后用下面的方法写到相册中

MediaStore.Images.Media.insertImage(AddCommercial.this.getContentResolver(),

file.getAbsolutePath(), name, null);

2、通知系统跟新手机储存目录

扫描拍照后的指定文件(推荐)

Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);

Uri uri = Uri.fromFile(new File(fileName));

System.out.println(fileName+"uriuri:::"+uri);

intent.setData(uri);

sendBroadcast(intent);

扫描整个sd卡(扫描费时间)

sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://" + Environment.getExternalStorageDirectory())));

FileOutputStream b = null;

Bitmap bitmap = null;

String wenjian = "文件名" ;

try {

String sdStatus = Environment.getExternalStorageState();

if (!sdStatus.equals(Environment.MEDIA_MOUNTED)) { // 检测sd是否可用

MyToast.MyShow(AddCommercial.this, "请确认已经插入SD卡");

return;

}

Bundle bundle = data.getExtras();

bitmap = (Bitmap) bundle.get("data");// 获取相机返回的数据，并转换为Bitmap图片格式

File appDir = new File(Environment.getExternalStorageDirectory(), wenjian);

if (!appDir.exists()) {

appDir.mkdir();

}

String name = System.currentTimeMillis() + ".jpg";

File file = new File(appDir, name);

fileName = Environment.getExternalStorageDirectory()+"/"+wenjian+"/"+name;

cameralist.add(fileName);

b = new FileOutputStream(file);

bitmap.compress(Bitmap.CompressFormat.JPEG, 100, b);// 把数据写入文件

MediaStore.Images.Media.insertImage(AddCommercial.this.getContentResolver(),

file.getAbsolutePath(), name, null);

Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);

Uri uri = Uri.fromFile(new File(fileName));

System.out.println(fileName+"uriuri:::"+uri);

intent.setData(uri);

sendBroadcast(intent);

} catch (Exception e) {

e.printStackTrace();

} finally {

try {

b.flush();

b.close();

} catch (Exception e) {

e.printStackTrace();

}

}
