在Android上获取图像的文件路径

发布到Twitter时，需要在发布请求中发送图片在设备上的实际路径。我发现很难找到实际的路径，而且经常会发现错误的路径。

为了解决这个问题，一旦有了a

Bitmap

URI getImageUri()

tempUriUri

这是生产代码，并且经过了自然测试。;-)

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); }
