@PercyPercy的轻微修改版本-它不会抛出，如果有任何错误，它只返回null:

public String getPathFromMediaUri(Context context, Uri uri) {
    String result = null;

    String[] projection = { MediaStore.Images.Media.DATA };
    Cursor cursor = context.getContentResolver().query(uri, projection, null, null, null);
    int col = cursor.getColumnIndex(MediaStore.Images.Media.DATA);
    if (col >= 0 && cursor.moveToFirst())
        result = cursor.getString(col);
    cursor.close();

    return result;
}

在这里，我将向您展示如何创建一个BROWSE按钮，当您单击它时，它将打开SD卡，您将选择一个文件，结果您将获得所选文件的文件名和文件路径:

一个你要按的按钮

browse.setOnClickListener(new OnClickListener()
{
    public void onClick(View v)
    {
        Intent intent = new Intent();
        intent.setAction(Intent.ACTION_PICK);
        Uri startDir = Uri.fromFile(new File("/sdcard"));
        startActivityForResult(intent, PICK_REQUEST_CODE);
    }
});

获取结果文件名和文件路径的函数

protected void onActivityResult(int requestCode, int resultCode, Intent intent)
{
    if (requestCode == PICK_REQUEST_CODE)
    {
        if (resultCode == RESULT_OK)
        {
            Uri uri = intent.getData();

            if (uri.getScheme().toString().compareTo("content")==0)
            {
                Cursor cursor =getContentResolver().query(uri, null, null, null, null);
                if (cursor.moveToFirst())
                {
                    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);//Instead of "MediaStore.Images.Media.DATA" can be used "_data"
                    Uri filePathUri = Uri.parse(cursor.getString(column_index));
                    String file_name = filePathUri.getLastPathSegment().toString();
                    String file_path=filePathUri.getPath();
                    Toast.makeText(this,"File Name & PATH are:"+file_name+"\n"+file_path, Toast.LENGTH_LONG).show();
                }
            }
        }
    }
}

下面API 19使用这段代码从URI中获取文件路径:

public String getRealPathFromURI(Context context, Uri contentUri) {
  Cursor cursor = null;
  try { 
    String[] proj = { MediaStore.Images.Media.DATA };
    cursor = context.getContentResolver().query(contentUri,  proj, null, null, null);
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
  } finally {
    if (cursor != null) {
      cursor.close();
    }
  }
}

试试这个

不过，如果你想要得到真正的答案，你可以试试我的答案。以上答案对我没有帮助。

解释:-这个方法获取URI，然后检查你的Android设备的API级别，根据API级别，它将生成真实路径。生成真实路径方法的代码根据API级别不同而不同。

method to get the Real path from URI @SuppressLint("ObsoleteSdkInt") public String getPathFromURI(Uri uri){ String realPath=""; // SDK < API11 if (Build.VERSION.SDK_INT < 11) { String[] proj = { MediaStore.Images.Media.DATA }; @SuppressLint("Recycle") Cursor cursor = getContentResolver().query(uri, proj, null, null, null); int column_index = 0; String result=""; if (cursor != null) { column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); realPath=cursor.getString(column_index); } } // SDK >= 11 && SDK < 19 else if (Build.VERSION.SDK_INT < 19){ String[] proj = { MediaStore.Images.Media.DATA }; CursorLoader cursorLoader = new CursorLoader(this, uri, proj, null, null, null); Cursor cursor = cursorLoader.loadInBackground(); if(cursor != null){ int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); cursor.moveToFirst(); realPath = cursor.getString(column_index); } } // SDK > 19 (Android 4.4) else{ String wholeID = DocumentsContract.getDocumentId(uri); // 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); int columnIndex = 0; if (cursor != null) { columnIndex = cursor.getColumnIndex(column[0]); if (cursor.moveToFirst()) { realPath = cursor.getString(columnIndex); } cursor.close(); } } return realPath; } Use this method like this Log.e(TAG, "getRealPathFromURI: "+getPathFromURI(your_selected_uri) );

输出:

04-06 12:39:46,993 6138-6138/com。qtm E/tag: getrealthfro到处都是: /存储/ emulated / 0 /视频/ avengers_infinity_war_4k_8k-7680x4320。jpg

不幸的是，上面提到的答案没有一个管用。最后我成功了。

这将把URI转换为Image。

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 filePath = cursor.getString(columnIndex);
cursor.close();

下面的代码我用来选择图像。

Intent intent = new Intent(Intent.ACTION_PICK,MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

startActivityForResult(intent, SELECT_PICTURES);

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);
}
