在棒棒糖的android始终文件路径返回NULL [英] file path return null always in lollipop android

问题描述

这是当我从内部存储（库）获得的图像我的code。 在棒棒糖文件路径返回始终为空。

 如果（要求code == PICK_IMAGE）{
        如果（结果code == RESULT_OK）{
            //形象成功地挑
            //发射载活动
            乌里selectedImage = data.getData（）;
            的String [] filePathColumn = {MediaStore.Images.Media.DATA};
            光标光标= getContentResolver（）查询（selectedImage，filePathColumn，NULL，NULL，NULL）;
            cursor.moveToFirst（）;
            参数：columnIndex = cursor.getColumnIndex（MediaStore.Images.Media.DATA）;
            FILE_PATH = cursor.getString（参数：columnIndex）;
            Log.d（的getClass（）的getName（），FILE_PATH+ FILE_PATH）;
            =了fileURI Uri.parse（文件：//+ FILE_PATH）;
            cursor.close（）;
            launchUploadActivity（真，PICK_IMAGE）;
        }否则，如果（结果code == RESULT_CANCELED）{
            //用户取消记录
            Toast.makeText（getApplicationContext（），用户取消图像选择，Toast.LENGTH_SHORT）.show（）;
        } 其他 {
            //无法录制视频
            Toast.makeText（getApplicationContext（）！对不起未能挑形象，Toast.LENGTH_SHORT）.show（）;
        }
 

解决方案

感谢名单的是，我找到了解决办法。

 乌里selectedImage = data.getData（）;
            字符串wholeID = DocumentsContract.getDocumentId（selectedImage）;

            //分割在结肠，使用数组中的第二项
            串的id = wholeID.split（：）[1];

            字符串[]列= {MediaStore.Images.Media.DATA};

            //其中id等于
            字符串SEL = MediaStore.Images.Media._ID +=;

            光标光标= getContentResolver（）。
                                      查询（MediaStore.Images.Media.EXTERNAL_CONTENT_URI，
                                      列，SEL，新的String [] {ID}，NULL）;

            字符串文件路径=;

            INT参数：columnIndex = cursor.getColumnIndex（列[0]）;

            如果（cursor.moveToFirst（））{
                文件路径= cursor.getString（参数：columnIndex）;
            }
            cursor.close（）;
            setImageFromIntent（文件路径）;
 

this is my code when i'm getting image from internal storage (gallery). In lollipop file path return always null.

if (requestCode == PICK_IMAGE)  {
        if(resultCode == RESULT_OK){
            //image successfully picked
            // launching upload activity
            Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };
            Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);
            cursor.moveToFirst();
            columnindex = cursor.getColumnIndex(MediaStore.Images.Media.DATA);
            file_path = cursor.getString(columnindex);
            Log.d(getClass().getName(), "file_path"+file_path);
            fileUri = Uri.parse("file://" + file_path);
            cursor.close();
            launchUploadActivity(true, PICK_IMAGE);
        }else if (resultCode == RESULT_CANCELED) {
            // user cancelled recording
            Toast.makeText(getApplicationContext(),"User cancelled image  selection", Toast.LENGTH_SHORT).show();
        } else {
            // failed to record video
            Toast.makeText(getApplicationContext(),"Sorry! failed to pick image", Toast.LENGTH_SHORT).show();
        }

解决方案

Thanx all,I found the solution.

    Uri selectedImage = data.getData();
            String wholeID = DocumentsContract.getDocumentId(selectedImage);

            // Split at colon, use second item in the array
            String id = wholeID.split(":")[1];

            String[] column = { MediaStore.Images.Media.DATA };     

            // where id is equal to             
            String sel = MediaStore.Images.Media._ID + "=?";

            Cursor cursor = getContentResolver().
                                      query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, 
                                      column, sel, new String[]{ id }, null);

            String filePath = "";

            int columnIndex = cursor.getColumnIndex(column[0]);

            if (cursor.moveToFirst()) {
                filePath = cursor.getString(columnIndex);
            }   
            cursor.close();
            setImageFromIntent(filePath);
