我正在创建一个存储位图图像的目录。这是我的代码:
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/ABC");
myDir.mkdirs();
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Image-" + n + ".jpg";
File file = new File(myDir, fname);
Log.i(TAG, "" + file);
if (file.exists())
file.delete();
try {
FileOutputStream out = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://" + Environment.getExternalStorageDirectory())));
但是这个文件夹没有显示在gallery.I我正在使用Android" Marshmallow"版本。任何人都可以帮助我吗?
答案 0 :(得分:1)
使用此广播
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Intent mediaScanIntent = new Intent(
Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
Uri contentUri = Uri.fromFile(out); //out is your file you saved/deleted/moved/copied
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
} else {
sendBroadcast(new Intent(
Intent.ACTION_MEDIA_MOUNTED,
Uri.parse("file://"
+ Environment.getExternalStorageDirectory())));
}
