如何获取 edittxt 中的值，再放入 URL 中

private Button btnLogin;
private EditText txtPub;
private EditText txtPriv;
final Context context = this;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.loginfirst);
    btnLogin = (Button)findViewById(R.id.btnEnter);
    btnLogin.setOnClickListener(this);
    txtPub = (EditText)findViewById(R.id.textPublic);
    txtPriv = (EditText)findViewById(R.id.textPrivate);
}

@Override
public void onClick(View arg0) {
    Intent intent = new Intent(context, WebViewActivity.class);
    startActivity(intent);
}

WebViewActivity.class

    private WebView webView;
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.webview);
    webView = (WebView) findViewById(R.id.web_view);
    webView.getSettings().setJavaScriptEnabled(true);
    webView.loadUrl("http://url.com/txtpub+txtprive");
}

如何获取 edittxt txtpub 和 txtpriv 的值，然后放进url的webviewactivity类中？我想把txtpub 和txtpriv 的值放入url中，怎么实现呢？

String txtpubStr=txtPub.getText().toString();

Intent intent = new Intent(context, WebViewActivity.class);
intent.putExtra("txtPub", txtpubStr)
startActivity(intent);

然后在WebViewActivity中

Intent intent=getIntent();
String txtPub=intent.getStringExtra("txtPub")//注意这里的"txtPub"与之前的要一致
