android标记 pdf阅读器,Android pdf阅读器

我想使用

Android pdf库

http://andpdf.sourceforge.net/,但我有同样的错误.日志：

ST='file 'no file selected' not found'

ST='reading page 1, zoom:1.0'

我的课程：

public class Reader extends PdfViewerActivity {

public int getPreviousPageImageResource() { return R.drawable.left_arrow; }

public int getNextPageImageResource() { return R.drawable.right_arrow; }

public int getZoomInImageResource() { return R.drawable.zoom_in; }

public int getZoomOutImageResource() { return R.drawable.zoom_out; }

public int getPdfPasswordLayoutResource() { return R.layout.pdf_file_password; }

public int getPdfPageNumberResource() { return R.layout.dialog_pagenumber; }

public int getPdfPasswordEditField() { return R.id.etPassword; }

public int getPdfPasswordOkButton() { return R.id.btOK; }

public int getPdfPasswordExitButton() { return R.id.btExit; }

public int getPdfPageNumberEditField() { return R.id.pagenum_edit; }

}

和

public class StartScreen extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

// TODO Auto-generated method stub

super.onCreate(savedInstanceState);

Intent intent = new Intent(this, Reader.class);

intent.putExtra(PdfViewerActivity.EXTRA_PDFFILENAME, "/sdcard/test.pdf");

startActivity(intent);

}

}
