How can I display a pdf document into a TextView?

问题

I want to read pdf files and display contents on TextView. is it possible ? or just show pdf into WebView or pdfViewer?

i want to do like it,

public class MainActivity extends Activity {

private TextView showText;
String url="http://www.adobe.com/devnet/acrobat/pdfs/pdf_open_parameters.pdf";

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    showText= (TextView)this.findViewById(R.id.showtext);
    showText.setText( ++ convertPdfTotext ++);


}


public void convertPdfTotext(View view)
{

}

}

If you want to use it in text view you can convert it with itext as string,but you'll loose formatting:

    PdfTextExtractor parser =new PdfTextExtractor(new PdfReader("C:/Text.pdf"));
parser.getTextFromPage(3);

Use WebView instead and you can enable even zoom.

WebView mWebView=new WebView(MyPdfViewActivity.this);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setPluginsEnabled(true);
mWebView.loadUrl("https://docs.google.com/gview?embedded=true&url="+LinkTo);
