在浏览项目的时候，发现有这么一个不错的工具【android-pdfview】，直接可以像浏览txt文档一样浏览pdf文档，这里我贴一下代码，主要是给自己标记一下。

点我下载android-pdfview工具

在布局文件中：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >    <include layout="@layout/a1_head" />    <com.joanzapata.pdfview.PDFView        android:id="@+id/pdfView"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:background="#444444" /></LinearLayout>

然后在activity中：

public class PdfViewActivity extends BaseActivity implements OnPageChangeListener{private PDFView pdfView;private int pageNum=1;private String filePath = Environment.getExternalStorageDirectory().getPath() + "/myTest.pdf";@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_pdf_view);copyFileToSdcard();setActivityHeaderTitle(R.string.data_activity_name);getHeaderLeftButton().setImageResource(R.drawable.icon_back);File file=new  File(filePath);pdfView=(PDFView) findViewById(R.id.pdfView);pdfView.fromFile(file)        .defaultPage(pageNum)        .onPageChange(PdfViewActivity.this)        .load();}@Overridepublic void onPageChanged(int page, int pageCount) {page=pageNum;}private void copyFileToSdcard() {InputStream inputstream = getResources().openRawResource(R.raw.ceshi);byte[] buffer = new byte[1024];int count = 0;FileOutputStream fos = null;try {fos = new FileOutputStream(new File(filePath));while ((count = inputstream.read(buffer)) > 0) {fos.write(buffer, 0, count);}fos.close();} catch (FileNotFoundException e1) {e1.printStackTrace();Toast.makeText(PdfViewActivity.this, "Check your sdcard", Toast.LENGTH_LONG).show();} catch (IOException e) {e.printStackTrace();}}}
