是什么在jblough / Android的-PDF查看器库的路径？ [英] What's the path in jblough / Android-Pdf-Viewer-Library?

问题描述

在以下网站寻找：
https://github.com/jblough/Android-Pdf-Viewer-Library

他列在下code：

 意向意图=新意图（这一点，YourPdfViewerActivity.class）;
intent.putExtra（PdfViewerActivity.EXTRA_PDFFILENAME，PATH TO PDF GOES HERE）;
startActivity（意向）;
 

会有什么这条道路是在哪里我可以把这个PDF文件？

我已经把测试PDF文件中夹入资产价值，资源/原材料。从数据/数据​​/项目DDMS推了文件，并在libs文件夹也是如此。我尝试以下，但我仍然得到找不到文件：

 字符串路径= Environment.getExternalStorageDirectory（）的getPath（）。
字符串路径= Environment.getExternalStorageDirectory（）getAbsolutePath（）+的test.pdf。
字符串路径=android.resource：//com.example.test3/raw/test.pdf
字符串路径=文件：///android_assets/test.pdf;
字符串路径= Environment.getExternalStorageDirectory（）getAbsolutePath（）+/test.pdf。
 

解决方案

 最后文件cacheDir = context.getDir（缓存，0）;
如果cacheDir.mkdirs（）（cacheDir.exists（）！）;
最终文件fil​​eContent =新的文件（cacheDir则为test1.pdf）;
字符串路径= Environment.getExternalStorageDirectory（）getAbsolutePath（）+/test1.pdf。
PATH = fileContent.getPath（）;
意向意图=新意图（这一点，MainActivity.class）;
intent.putExtra（PdfViewerActivity.EXTRA_PDFFILENAME，路径）;
startActivity（意向）;
 

运行它第一次，它创建了一个文件夹，然后我把该文件夹中文件并再次运行它，它是能够找到该文件。从DDMS放置在文件。通过Selvin回答。

Looking at the following website: https://github.com/jblough/Android-Pdf-Viewer-Library

He's listed the following code:

Intent intent = new Intent(this, YourPdfViewerActivity.class);
intent.putExtra(PdfViewerActivity.EXTRA_PDFFILENAME, "PATH TO PDF GOES HERE");
startActivity(intent);

What will that path be and where I be placing this PDF file?

I have placed a test PDF file in assests folder, res/raw. Pushed a file from the ddms in data/data/project, and in libs folder as well. I tried the following but I am still getting file not found:

String path = Environment.getExternalStorageDirectory().getPath();
String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "test.pdf";
String path = "android.resource://com.example.test3/raw/test.pdf";
String path = "file:///android_assets/test.pdf";
String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/test.pdf";

解决方案

final File cacheDir = context.getDir("cache", 0);
if(!cacheDir.exists()) cacheDir.mkdirs();
final File fileContent = new File(cacheDir, "test1.pdf");
String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/test1.pdf";
path = fileContent.getPath();
Intent intent = new Intent(this, MainActivity.class);
intent.putExtra(PdfViewerActivity.EXTRA_PDFFILENAME, path);
startActivity(intent);

Ran it first time, it created that folder, then I placed the file in that folder and ran it again and it was able to find the file. Placed the file from the ddms. Answered by Selvin.
