android– 如何从图库中选择视频并获得真实路径？

概述我可以用这段代码打开画廊,Intentintent=newIntent(Intent.ACTION_PICK);intent.setType("video/*");intent.setAction(Intent.ACTION_GET_CONTENT);startActivityForResult(Intent.createChooser(intent,"SelectVideo"),PICK_VIDEO_REQ

我可以用这段代码打开画廊,

    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 );

它适用于三星galaxy S5.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仅显示视频？

返回结果时,如何获取所选视频的真实路径？

解决方法:

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;    }
