试试这个可能对你有帮助
public void takePicture(){
Intent imgIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
File imagesFolder = new File(Environment.getExternalStorageDirectory(), "ImagesApp");
imagesFolder.mkdirs(); // <----
File image = new File(imagesFolder, "temp.jpg");
Uri uriSavedImage = Uri.fromFile(image);
imgIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
startActivityForResult(imgIntent,IMAGE_CAPTURE_REQUEST_CODE);
}

您可以使用以下代码
private String save(Bitmap bitmap)
{
File save_path = null;
if (android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED))
{
try
{
File sdCard = Environment.getExternalStorageDirectory();
File dir = new File(sdCard.getAbsolutePath() + "/DirName");
dir.mkdirs();
File file = new File(dir, "DirName_"+new SimpleDateFormat("yyyyMMdd_HHmmss").format(Calendar.getInstance().getTime())+ ".png");
save_path = file;
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100,baos);
FileOutputStream f = null;
f = new FileOutputStream(file);
MediaScannerConnection.scanFile(this, new String[]{file.getAbsolutePath()}, null, null);
if (f != null)
{
f.write(baos.toByteArray());
f.flush();
f.close();
}
}
catch (Exception e)
{
// TODO: handle exception
}
}
return String.valueOf(save_path);
}
希望对你有所帮助...

试试下面的代码
private void createDirectoryAndSaveFile(Bitmap imageToSave, String fileName) {
File direct = new File(Environment.getExternalStorageDirectory() + "/DirName");
if (!direct.exists()) {
File wallpaperDirectory = new File("/sdcard/DirName/");
wallpaperDirectory.mkdirs();
}
File file = new File(new File("/sdcard/DirName/"), fileName);
if (file.exists()) {
file.delete();
}
try {
FileOutputStream out = new FileOutputStream(file);
imageToSave.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
