问题描述
当我开始拍照意图我给它一个文件名,我想它的使用。当我得到这个在手机上使用手机默认的文件名。这是毫无帮助,我以后需要在应用程序中的图像名称。
相机意图code ...
公共无效的onClick(视图查看){
字符串currentDateTimeString = DateFormat.getDateInstance()格式(新的Date())。
的System.out.println(currentDateTimeString);
文件名=(/ SD卡/+ currentDateTimeString +.JPG);
意向意图=新的意图(MediaStore.ACTION_IMAGE_CAPTURE);
档案文件=新的文件(Environment.getExternalStorageDirectory(),文件名);
outputFileUri = Uri.fromFile(文件);
intent.putExtra(MediaStore.EXTRA_OUTPUT,outputFileUri);
startActivityForResult(意向,TAKE_PICTURE);
文件类型=图像/ JPEG;
}
解决方案
詹姆斯,
下面是我用它来拍摄图像,并把它保存到我的选择(子文件夹我的应用程序的名称)。
的位置功能 公共无效imageFromCamera(){
意向意图=新的意图(android.media.action.IMAGE_CAPTURE);
如果(!Environment.getExternalStorageState()。等于(Environment.MEDIA_MOUNTED)){
Log.d(TAG,无SD卡);
} 其他 {
mImageFile =新的文件(Environment.getExternalStorageDirectory()+文件分割符+MyApp的,
PIC+ System.currentTimeMillis的()+JPG);
mTempImagePath = mImageFile.getAbsolutePath();
intent.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(mImageFile));
startActivityForResult(意向,TAKE_PICTURE);
}
}
When I begin the camera intent I give it a file name I would like it to use. When I get this on the phone it uses the phones default file name. Which is no help as I need the image name later in the app.
Camera intent code...
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";
}
解决方案
James,
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).
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);
}
}
