将视频保存到内部存储

Question

我有一个 videoView，它从与 android 画廊中的视频文件相对应的路径播放视频

 VideoView videoView1 = (VideoView)promptsView.findViewById(R.id.videoView09);
            String SrcPath = "/storage/emulated/0/DCIM/Camera/20150824_210148.mp4";
            videoView1.setVideoPath(SrcPath);
            videoView1.requestFocus();
            videoView1.start();

现在，我需要以某种方式将此 videoView 中的视频私下存储到我的应用程序的内部存储中。

我已经成功地使用照片来做到这一点

public String saveImageToInternalStorage(Bitmap image, String imgRequestedName) {
    ContextWrapper cw = new ContextWrapper(getActivity());
    File directory = cw.getDir("imageDir", Context.MODE_PRIVATE);
    File mypath=new File(directory,imgRequestedName+".jpg");
    String loc = mypath.getAbsolutePath();
    FileOutputStream fos = null;
    try {

        fos = new FileOutputStream(mypath);
        image.compress(Bitmap.CompressFormat.JPEG, 70, fos);
        SharedPreferences pref = getActivity().getApplicationContext().getSharedPreferences("MyPref", Context.MODE_PRIVATE);
        final SharedPreferences.Editor editor = pref.edit();
        editor.putInt("totalImageCount",(pref.getInt("totalImageCount",0))+1);
        editor.commit();

        fos.close();
    } catch (Exception e) {
        e.printStackTrace();
    }

    return mypath.getAbsolutePath();
}

我怎样才能对视频做同样的事情？

我如何从内部存储读取视频？

Answer 1

以下是将视频私下保存到应用程序内部存储的代码。还有从内部存储读取视频的代码。希望这可以帮助。

//For saving Video...

private void saveVideoToInternalStorage (String filePath) {

    File newfile;

    try {

        File currentFile = new File(filePath);
        String fileName = currentFile.getName();

        ContextWrapper cw = new ContextWrapper(getApplicationContext());
        File directory = cw.getDir("videoDir", Context.MODE_PRIVATE);


        newfile = new File(directory, fileName);

        if(currentFile.exists()){

            InputStream in = new FileInputStream(currentFile);
            OutputStream out = new FileOutputStream(newfile);

            // Copy the bits from instream to outstream
            byte[] buf = new byte[1024];
            int len;

            while ((len = in.read(buf)) > 0) {
                out.write(buf, 0, len);
            }

            in.close();
            out.close();

            Log.v("", "Video file saved successfully.");

        }else{
            Log.v("", "Video saving failed. Source file missing.");
        }



    } catch (Exception e) {
        e.printStackTrace();
    }

}

private void loadVideoFromInternalStorage(String filePath){

    Uri uri = Uri.parse(Environment.getExternalStorageDirectory()+filePath);
    myVideoView.setVideoURI(uri);

}
