Question

我正试图从我的活动中启动我的应用程序在Android市场的页面。我是新手，也许我正在编写错误的代码，这是我在note.class中写的

 import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.webkit.WebView;
import android.widget.Button;

public class Note extends Activity{
    WebView mWebView;
    WebView tWebView;
    @Override
     protected void onCreate(Bundle savedInstanceState) {
                    // TODO Auto-generated method stub
            super.onCreate(savedInstanceState);
            setContentView(R.layout.note);

            mWebView = (WebView) findViewById(R.id.webview);    

               String text = "<html><head><meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\"></head><body>" + "<p align=\"justify\">"                
                     + getString(R.string.fulldescription)+ "</p> " + "</body></html>";

                    mWebView.loadData(text, "text/html", "utf-8");

                    //seconda webview dove dormire-mangiare

                    tWebView = (WebView) findViewById(R.id.webview2);    

                       String text2 = "<html><head><meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\"></head><body>" + "<p align=\"justify\">" + getString(R.string.descriptionspart2) + "</p> " 
                                     + "</body></html>";       

                            tWebView.loadData(text2, "text/html", "utf-8");

            Button bnt = (Button)findViewById(R.id.back1);

            bnt.setOnClickListener(new View.OnClickListener() {

       public void onClick(View view) {

                    // avvia la prossima activity del primo video

           Intent i = new Intent(view.getContext(), Clipvideo1.class);

           view.getContext().startActivity(i);

                }

            });
            Button app2 = (Button)findViewById(R.id.buy_app2);
            app2.setOnClickListener(new View.OnClickListener() {

                public void onClick(View v) {
                    Intent intent = new Intent(Intent.ACTION_VIEW);
                    intent.setData(Uri.parse("market://details?id=com.wocmultimedia.Machu2a"));
                    startActivity(intent);
                    // TODO Auto-generated method stub

                }
            });

        }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu, menu);
    return true;
    }
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
    // Handle item selection
    switch (item.getItemId()) {
    case R.id.delfino:
        Intent g = new Intent(this, Main.class);
           startActivity(g);
      return true;
    case R.id.note:
        Intent l = new Intent(this, Note.class);
    startActivity(l);
        return true;
    case R.id.clipvideo:
        Intent k = new Intent(this, Clipvideo1.class);
           startActivity(k);
         return true;
    case R.id.map:
        Intent p = new Intent(this, Map.class);
           startActivity(p);
         return true;
    default:
        return super.onOptionsItemSelected(item);
    }
    }


    }

这是note.xml布局
