相机意图android

[英]Camera intent android

When I begin the camera intent I give it a file name I would like it to use. 当我开始摄影机意图时,我为其指定了一个文件名。 When I get this on the phone it uses the phones default file name. 当我在电话上收到此消息时,它将使用电话的默认文件名。 Which is no help as I need the image name later in the app. 这没有帮助,因为稍后在应用程序中我需要图像名称。

Camera intent code... 相机意图代码...

public void onClick(View view) {
  String currentDateTimeString = DateFormat.getDateInstance().format(new Date());
  System.out.println(currentDateTimeString); 
  filename = ("/sdcard/" + currentDateTimeString + ".jpg");

  Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
  File file = new File(Environment.getExternalStorageDirectory(), filename);

  outputFileUri = Uri.fromFile(file);
  intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
  startActivityForResult(intent, TAKE_PICTURE);
  filetype = "image/jpeg";

}

James, 詹姆士,

Here is the function I use to capture an image and save it to a location of my choosing (sub folder with my app name). 这是我用来捕获图像并将其保存到我选择的位置(具有我的应用名称的子文件夹)的功能。

public void imageFromCamera() {
    Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
    if (!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)){
        Log.d(TAG, "No SDCARD");
    } else {
        mImageFile = new File(Environment.getExternalStorageDirectory()+File.separator+"MyApp",  
            "PIC"+System.currentTimeMillis()+".jpg");
        mTempImagePath = mImageFile.getAbsolutePath();
        intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(mImageFile));
        startActivityForResult(intent, TAKE_PICTURE);
    }
}
