Java 使用MuPDF读取联机PDF文件

我有两个问题 1） 注释无效 2） 我想在线阅读pdf文档

我使用此链接构建MuPDF

1） 我得到了项目mupdf/platform/android 我运行默认的应用程序注释工作正常，但我将该项目创建到他们希望保存但注释未保存的库文件中

2） 它将读取本地文件，但我想读取在线文件也。我的android代码

pdf = (TextView) findViewById(R.id.pdf);
    onPdf = (TextView) findViewById(R.id.onPdf);

    pdf.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            Uri uri = Uri.parse(path);

            Intent intent = new Intent(context, MuPDFActivity.class);

            intent.setAction(Intent.ACTION_VIEW);

            intent.setData(uri);

            startActivity(intent);


        }
    });

    onPdf.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            Uri uri = Uri.parse(netPath);


            Intent intent = new Intent(context, MuPDFActivity.class);

            intent.setAction(Intent.ACTION_VIEW);

            intent.setData(uri);

            startActivity(intent);

        }
    });

修改的MuPDFActivity-I更改所有文件都是打开的openBuffer方法

private MuPDFCore openBuffer(byte buffer[]) {
    System.out.println("Trying to open byte buffer");
    try {
        String magic = "";
        core = new MuPDFCore(this, buffer, magic);
        // New file: drop the old outline data
        OutlineActivityData.set(null);
    } catch (Exception e) {
        System.out.println(e);
        return null;
    }
    return core;
}

我的主食

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

我下载PDF文件并转换成字节，然后在MuPDF核心中打开

下载文件

byte buffer[] = null;
    HttpURLConnection urlConnection = null;
    try {

        urlConnection = (HttpURLConnection) urls[0].openConnection();
        urlConnection.setReadTimeout(TIMEOUT_READ);
        InputStream inputStream = urlConnection.getInputStream();

        int len = inputStream.available();
        buffer = new byte[len];

        // inputStream.read(buffer, 0, len);

        while ((len = inputStream.read(buffer)) != -1) {
            byteBuffer.write(buffer, 0, len);
        }
        Log.e("Length", "" + byteBuffer.size());
        inputStream.close();
        // and then we can return your byte array.

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

        });

开核

RelativeLayout mupdfWrapper;
MuPDFCore core;
public byte[] buffer;
mupdfWrapper = (RelativeLayout) viewRoot
                .findViewById(R.id.mupdf_wrapper);
        // Intent intent =new Intent(getActivity(),MuPDFActivity.class);
        // startActivity(intent);

        core = new MuPDFCore(getActivity(), buffer, "");
        MuPDFReaderView mDocView = new MuPDFReaderView(getActivity());
        mDocView.setAdapter(new MuPDFPageAdapter(getActivity(), core));
        mupdfWrapper.addView(mDocView, new LayoutParams(
                LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));

你解决这个问题了吗？试试下面我为这个模型所做的回答。你能不能分享这个问题的完整代码，因为我不能让它工作？多谢各位

RelativeLayout mupdfWrapper;
MuPDFCore core;
public byte[] buffer;
mupdfWrapper = (RelativeLayout) viewRoot
                .findViewById(R.id.mupdf_wrapper);
        // Intent intent =new Intent(getActivity(),MuPDFActivity.class);
        // startActivity(intent);

        core = new MuPDFCore(getActivity(), buffer, "");
        MuPDFReaderView mDocView = new MuPDFReaderView(getActivity());
        mDocView.setAdapter(new MuPDFPageAdapter(getActivity(), core));
        mupdfWrapper.addView(mDocView, new LayoutParams(
                LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
