尝试从Uri获取图像文件路径

public void getImageFilePath(Context context, Uri uri) {

    Cursor cursor = context.getContentResolver().query(uri, null, null, null, null);
    cursor.moveToFirst();
    String image_id = cursor.getString(0);
    image_id = image_id.substring(image_id.lastIndexOf(":") + 1);
    cursor.close();
    cursor = context.getContentResolver().query(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, null, MediaStore.Images.Media._ID + " = ? ", new String[]{image_id}, null);
    cursor.moveToFirst();
    String path = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
    cursor.close();
    upLoadImageOrLogo(path);
}

尝试从Uri获取图像文件路径

public void getImageFilePath(Context context, Uri uri) {

    Cursor cursor = context.getContentResolver().query(uri, null, null, null, null);
    cursor.moveToFirst();
    String image_id = cursor.getString(0);
    image_id = image_id.substring(image_id.lastIndexOf(":") + 1);
    cursor.close();
    cursor = context.getContentResolver().query(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, null, MediaStore.Images.Media._ID + " = ? ", new String[]{image_id}, null);
    cursor.moveToFirst();
    String path = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
    cursor.close();
    upLoadImageOrLogo(path);
}

这里您可以得到文件的名称

String[] projection = {MediaStore.MediaColumns.DISPLAY_NAME};
                    Uri uri = data.getData();
                    String fileName = null;
                    ContentResolver cr = getActivity().getApplicationContext().getContentResolver();

                    Cursor metaCursor = cr.query(uri,
                            projection, null, null, null);
                    if (metaCursor != null) {
                        try {
                            if (metaCursor.moveToFirst()) {
                                fileName = metaCursor.getString(0);
                            }
                        } finally {
                            metaCursor.close();
                        }
                    }

如果你的系统版本在19以上，这对我来说是完美的，希望这能帮助你。
