我有两个问题 1)注释不起作用 2)我想在线阅读pdf文件
我使用此链接构建MuPDF http://mupdf.com/doc/how-to-build-mupdf-for-android
1)我得到项目mupdf / platform / android 我运行该默认应用程序注释工作正常,但我创建该项目到库文件,他们要求保存,但注释不保存。
2)它将读取本地文件,但我也想读取在线文件。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);
}
});
修改了MuPDFActivity - 我改变所有文件都打开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;
}

答案 0 :(得分:0)
我下载PDF文件并转换为字节并在MuPDF Core中打开。
下载档案
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();
});
开放核心
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));
