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();
                        }
                    }

只是对第一个答案进行了简单的更新:mActivity.managedQuery()现在已弃用。我已经用新方法更新了代码。

private String getRealPathFromURI(Uri contentUri) {
    String[] proj = { MediaStore.Images.Media.DATA };
    CursorLoader loader = new CursorLoader(mContext, contentUri, proj, null, null, null);
    Cursor cursor = loader.loadInBackground();
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    String result = cursor.getString(column_index);
    cursor.close();
    return result;
}

Android开发源码

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:

从图库中获取图像后，只需要在下面的方法中传递URI，仅适用于Android 4.4 (KitKat):

public String getPath(Uri contentUri) {// Will return "image:x*"

    String wholeID = DocumentsContract.getDocumentId(contentUri);

    // 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();
    return filePath;
}

像下面这样获取Uri。

//* get cursor like normal

Then

while (cursor.moveToNext()) {
    Uri uri = ContentUris.withAppendedId(
    MediaStore.Images.Media.EXTERNAL_CONTENT_URI, id);
}

完美地为我修复了这篇文章的代码:

  public static String getRealPathImageFromUri(Uri uri) {
        String fileName =null;
        if (uri.getScheme().equals("content")) {
            try (Cursor cursor = MyApplication.getInstance().getContentResolver().query(uri, null, null, null, null)) {
                if (cursor.moveToFirst()) {
                    fileName = cursor.getString(cursor.getColumnIndexOrThrow(ediaStore.Images.Media.DATA));
                }
            } catch (IllegalArgumentException e) {
                Log.e(mTag, "Get path failed", e);
            }
        }
        return fileName;
    }
