有一个免费的PDF阅读器，我可以用我的应用程序？

我要寻找一个PDF阅读器，可以搜索，高亮文本，查看用户想要的页面，并没有改变PDF文件的内容。就像Adobe Reader的，但对于Android可以实现为一个应用程序。

I am looking for a PDF Viewer that can search, highlight text, view the page that user wants, and without altering the contents of the PDF file. Just like Adobe Reader but for Android that can be implemented to a Application.

我已经发现了这个问题，Pdf浏览器的API /库Android应用示例code？，但我认为他在寻找一个器。这个问题为Android PDF阅读器库，我读了，查看PDF格式应该是本身以及用于该解决方案是使用外部应用

I have found this question "Pdf viewer api/library for android app sample code?" but I think his looking for a Reader. this question "pdf viewer library for android" I read that to view pdf it should be Natively and the solution for that is to use External Applications.

如果我使用外部应用程序，我希望外部应用程序接受PDF文件路径，页面查看和关键字搜索编程，但我认为，外部应用程序不会让我这样做。

If I use external application, I want the external application accepts PDF Filepath, Page to view, and Keyword for search programmatically but i think external application wont let me do that.

First.java

First.java

    String[] pdflist;
    File[] imagelist;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.main);

        File images = Environment.getExternalStorageDirectory();
        imagelist = images.listFiles(new FilenameFilter() {
            public boolean accept(File dir, String name) {
                return ((name.endsWith(".pdf")));
            }
        });
        pdflist = new String[imagelist.length];
        for (int i = 0; i < imagelist.length; i++) {
            pdflist[i] = imagelist[i].getName();
        }
        this.setListAdapter(new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, pdflist));
    }

    protected void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);
        String path = imagelist[(int) id].getAbsolutePath();
        openPdfIntent(path);
    }

    private void openPdfIntent(String path) {
        try {
            final Intent intent = new Intent(First.this, Second.class);
            intent.putExtra(PdfViewerActivity.EXTRA_PDFFILENAME, path);
            startActivity(intent);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
