Android 尝试使用pdfviewer.jar打开时未获取pdf的所有内容

我尝试使用

pdfviewer.jar

打开pdf，我得到了pdf文件，但显示的内容不完整。我不明白为什么会这样

我的代码是：

public class PdfActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.pdfviewer);

    AssetManager assetManager = getAssets();

    InputStream in = null;
    OutputStream out = null;
    File file = new File(getFilesDir(), "ABC.pdf");

    try {
        in = assetManager.open("ABC.pdf");
        out = openFileOutput(file.getName(), Context.MODE_WORLD_READABLE);

        copyFile(in, out);
        in.close();
        in = null;
        out.flush();
        out.close();
        out = null;
    } catch (Exception e) {
        Log.e("tag", e.getMessage());
    }

    Intent intent = new Intent(this, MyPdfViewerActivity.class);
    intent.putExtra(PdfViewerActivity.EXTRA_PDFFILENAME, getFilesDir()
            + "/ABC.pdf");
    startActivity(intent);

}

private void copyFile(InputStream in, OutputStream out) throws IOException {
    byte[] buffer = new byte[1024];
    int read;
    while ((read = in.read(buffer)) != -1) {
        out.write(buffer, 0, read);
    }
}
}

pdfViewer的二等舱：

public class MyPdfViewerActivity extends PdfViewerActivity {

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // TODO Auto-generated method stub
}

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;
}
}

“不完整”是什么意思？@Kedarnath文本被截短了。您可以发布输出的图像吗？在真实设备上检查它。@SiddharthVyas的输出即使在真实设备上也是一样的
