我有一个应用程序，可以使图片和上传。 上传要求的照片的文件路径，但我不能得到它。
这是我的代码：
public void maakfoto (View v) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, mImageCaptureUri);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
knop.setVisibility(Button.VISIBLE);
System.out.println(mImageCaptureUri);
}
}
请帮我得到的文件路径。
谢谢
Answer 1:
张贴到Twitter需要张贴请求被发送设备上的图像的实际路径。 我发现它强大很难得到实际的路径，更往往不是我会得到错误的道路。
为了应对，一旦你有一个Bitmap ，我用它来从使用得到URI getImageUri() 随后，我用的是tempUri Uri实例，以获得实际路径，因为它是在设备上。
这是生产代码和自然测试。 ;-)
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
knop.setVisibility(Button.VISIBLE);
// CALL THIS METHOD TO GET THE URI FROM THE BITMAP
Uri tempUri = getImageUri(getApplicationContext(), photo);
// CALL THIS METHOD TO GET THE ACTUAL PATH
File finalFile = new File(getRealPathFromURI(tempUri));
System.out.println(mImageCaptureUri);
}
}
public Uri getImageUri(Context inContext, Bitmap inImage) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
return Uri.parse(path);
}
public String getRealPathFromURI(Uri uri) {
Cursor cursor = getContentResolver().query(uri, null, null, null, null);
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
return cursor.getString(idx);
}
Answer 2:
为了利用你要确定，你想保存的图像并传递作为额外的意图，例如路径的图片：
private void capture(){
String directoryPath = Environment.getExternalStorageDirectory() + "/" + IMAGE_DIRECTORY + "/";
String filePath = directoryPath+Long.toHexString(System.currentTimeMillis())+".jpg";
File directory = new File(directoryPath);
if (!directory.exists()) {
directory.mkdirs();
}
this.capturePath = filePath; // you will process the image from this path if the capture goes well
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra( MediaStore.EXTRA_OUTPUT, Uri.fromFile( new File(filePath) ) );
startActivityForResult(intent, REQUEST_CAPTURE);
}
我只是复制从另一个答案我给上面的部分。
不过要提醒你有很多与你应该看出来的设备之间的图像捕捉行为inconsitencies的。
下面是我遇到了一些HTC的设备，它可以节省在我经过的位置，并在它的产生在设备上重复的图片默认位置的问题： 删除库图像之后拍摄的相机照片的意图
Answer 3:
尝试用mImageCaptureUri.getPath(); 通过以下方式：
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
//Get your Image Path
String Path=mImageCaptureUri.getPath();
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
knop.setVisibility(Button.VISIBLE);
System.out.println(mImageCaptureUri);
}
Answer 4:
我就按一下按钮这样做。
private static final int CAMERA_PIC_REQUEST = 1;
private View.OnClickListener OpenCamera=new View.OnClickListener() {
@Override
public void onClick(View paramView) {
// TODO Auto-generated method stub
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
NewSelectedImageURL=null;
//outfile where we are thinking of saving it
Date date = new Date();
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH-mm-ss");
String newPicFile = RecipeName+ df.format(date) + ".png";
String outPath =Environment.getExternalStorageDirectory() + "/myFolderName/"+ newPicFile ;
File outFile = new File(outPath);
CapturedImageURL=outFile.toString();
Uri outuri = Uri.fromFile(outFile);
cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, outuri);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
};
你可以从可变CapturedImageURL最近拍摄图像的URL
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
//////////////////////////////////////
if (requestCode == CAMERA_PIC_REQUEST) {
// do something
if (resultCode == RESULT_OK)
{
Uri uri = null;
if (data != null)
{
uri = data.getData();
}
if (uri == null && CapturedImageURL != null)
{
uri = Uri.fromFile(new File(CapturedImageURL));
}
File file = new File(CapturedImageURL);
if (!file.exists()) {
file.mkdir();
sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://"+Environment.getExternalStorageDirectory())));
}
}
}
Answer 5:
使用此功能来获得捕获图像路径
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
Uri mImageCaptureUri = intent.getData();
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
knop.setVisibility(Button.VISIBLE);
System.out.println(mImageCaptureUri);
//getImgPath(mImageCaptureUri);// it will return the Capture image path
}
}
public String getImgPath(Uri uri) {
String[] largeFileProjection = { MediaStore.Images.ImageColumns._ID,
MediaStore.Images.ImageColumns.DATA };
String largeFileSort = MediaStore.Images.ImageColumns._ID + " DESC";
Cursor myCursor = this.managedQuery(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
largeFileProjection, null, null, largeFileSort);
String largeImagePath = "";
try {
myCursor.moveToFirst();
largeImagePath = myCursor
.getString(myCursor
.getColumnIndexOrThrow(MediaStore.Images.ImageColumns.DATA));
} finally {
myCursor.close();
}
return largeImagePath;
}
Answer 6:
要获取Android的所有图像我使用下面的代码路径
public void allImages()
{
ContentResolver cr = getContentResolver();
Cursor cursor;
Uri allimagessuri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
String selection = MediaStore.Images.Media._ID + " != 0";
cursor = cr.query(allsongsuri, STAR, selection, null, null);
if (cursor != null) {
if (cursor.moveToFirst()) {
do {
String fullpath = cursor.getString(cursor
.getColumnIndex(MediaStore.Images.Media.DATA));
Log.i("Image path ", fullpath + "");
} while (cursor.moveToNext());
}
cursor.close();
}
}
Answer 7:
简单的合格意向第一
Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
和U将得到U上的图片路径onActivityResult
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
ImageView imageView = (ImageView) findViewById(R.id.imgView);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
}
