如何从图库中选择视频并获得它的真实路径？

我可以使用此代码打开图库，

    Intent intent = new Intent(Intent.ACTION_PICK);
    intent.setType("video/*");

    intent.setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(Intent.createChooser(intent, "Select Video"), PICK_VIDEO_REQUEST );

在三星Galaxy S5上运行良好。但在某些手机中，图像会随视频一起显示。

我需要对代码进行哪些更改才能打开图库以显示仅视频？

如何在返回结果时获取所选视频的真实路径？

以下是从图库中选择后获取视频路径的完整代码。

Intent intent = new Intent();
intent.setType("video/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Video"),REQUEST_TAKE_GALLERY_VIDEO);

public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == RESULT_OK) {
            if (requestCode == REQUEST_TAKE_GALLERY_VIDEO) {
                Uri selectedImageUri = data.getData();

                // OI FILE Manager
                filemanagerstring = selectedImageUri.getPath();

                // MEDIA GALLERY
                selectedImagePath = getPath(selectedImageUri);
                if (selectedImagePath != null) {

                    Intent intent = new Intent(HomeActivity.this,
                            VideoplayAvtivity.class);
                    intent.putExtra("path", selectedImagePath);
                    startActivity(intent);
                }
            }
        }
    }

    // UPDATED!
    public String getPath(Uri uri) {
        String[] projection = { MediaStore.Video.Media.DATA };
        Cursor cursor = getContentResolver().query(uri, projection, null, null, null);
        if (cursor != null) {
            // HERE YOU WILL GET A NULLPOINTER IF CURSOR IS NULL
            // THIS CAN BE, IF YOU USED OI FILE MANAGER FOR PICKING THE MEDIA
            int column_index = cursor
                    .getColumnIndexOrThrow(MediaStore.Video.Media.DATA);
            cursor.moveToFirst();
            return cursor.getString(column_index);
        } else
            return null;
    }

您将从此方法获取真正的路径getPath

    final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;

    // DocumentProvider
    if (isKitKat && DocumentsContract.isDocumentUri(context, uri)) {
        // ExternalStorageProvider
        if (isExternalStorageDocument(uri)) {
            final String docId = DocumentsContract.getDocumentId(uri);
            final String[] split = docId.split(":");
            final String type = split[0];

            if ("primary".equalsIgnoreCase(type)) {
                return Environment.getExternalStorageDirectory() + "/" + split[1];
            }

            // TODO handle non-primary volumes
        }
        // DownloadsProvider
        else if (isDownloadsDocument(uri)) {

            final String id = DocumentsContract.getDocumentId(uri);

            Uri contentUri = null;

以下代码适用于我：

Intent videoPickIntent = new Intent(Intent.ACTION_PICK);
videoPickIntent.setType("video/*");
TheActivity.startActivityForResult(Intent.createChooser(videoPickIntent, "Please pick a video"), PickIntroductionVideo);

和onActivityResult：

if (requestCode != PickIntroductionVideo)
    return;
if (resultCode != Activity.RESULT_OK)
    return true;
String pickedVideoUrl = FarayanUtility.getRealPathFromUri(getContext(), data.getData());

方法FarayanUtility.getRealPathFromUri是：

public static 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();
        }
    }
}

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == RESULT_OK) {
            if (requestCode == 1) {
                Uri selectedVideoUri = data.getData();

                // OI FILE Manager
                String filemanagerstring = selectedVideoUri.toString();
                vidPath = filemanagerstring;

                // MEDIA GALLERY
                String selectedVideoPath = getPath(selectedVideoUri); 
                if (selectedVideoPath != null) {
                    vidPath = selectedVideoPath;
                }
            }
        }
    }

   //this function returns null when using IO file manager
    public String getPath(Uri uri) {
        String[] projection = { MediaStore.Video.Media.DATA };
        getContentResolver();
        Cursor cursor = getApplicationContext().getContentResolver().query(uri, projection, null, null, null);
        if (cursor != null) {
            int column_index = cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA);
            cursor.moveToFirst();
            return cursor.getString(column_index); 
        } else
            return null;
    }

如果getpath（）函数返回“ null”，则说明您未设置权限。您需要做的是在清单中粘贴以下内容：

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
 <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

将此标签粘贴在<application>标记之前，然后，在加载应用程序后，转到设置->应用程序-> YourApp->权限，然后将所有权限设置为true。完成此操作后，此代码应该可以正常运行

科特林版

 val intent = Intent(Intent.ACTION_PICK,MediaStore.Video.Media.EXTERNAL_CONTENT_URI)
 intent.type = "video/*";
 startActivityForResult(intent, REQUEST_VIDEO_CODE)

那么?

fun parsePath(uri: Uri?): String? {
        val projection = arrayOf(MediaStore.Video.Media.DATA)
        val cursor: Cursor? = contentResolver.query(uri!!, projection, null, null, null)
        return if (cursor != null) {
            val columnIndex: Int = cursor
                .getColumnIndexOrThrow(MediaStore.Video.Media.DATA)
            cursor.moveToFirst()
            cursor.getString(columnIndex)
        } else null
    }

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    if (resultCode == RESULT_OK) {
        when (requestCode) {
            REQUEST_VIDEO_CODE -> {
                val videoUri: Uri = data?.data!!
                val videoPath = getPath(videoUri)
                Log.d("TAG", "$videoPath is the path that you need...")
