Android在对话框中加载WebView

androiddialogwebview

我想在我的Webview中打开Twitter授权，而不是在浏览器中打开。 有没有好的教程可以教我如何在对话框中使用Webview并将其加载到对话框中？

你可以将对话框主题应用于包含 WebView 的常规活动。
我遇到问题了。我使用的是浏览器类型的应用程序，一旦我完成授权应用程序后，它就不会将我重定向到我的网页。相反，它会显示重定向，但它仍然停留在同一页上。有任何解决这类问题的想法吗？ - insomiac

  Context mContext = this;
  AlertDialog.Builder alert = new AlertDialog.Builder(mContext);

  alert.setTitle("Riga");
  WebView wv = new WebView(mContext);
  String html = "<html><body>some html here</body></html>";

  wv.loadData(html, "text/html", "UTF-8");
  alert.setView(wv);
  alert.setIcon(R.drawable.icon);
  alert.setPositiveButton("Yes", new DialogInterface.OnClickListener(){
     public void onClick(DialogInterface dialog, int id){
        Toast.makeText(getApplicationContext(), "Success", Toast.LENGTH_SHORT).show();
     }
  });
  alert.setNegativeButton("No", new DialogInterface.OnClickListener(){
     public void onClick(DialogInterface dialog, int id){
        Toast.makeText(getApplicationContext(), "Fail", Toast.LENGTH_SHORT).show();
     }
  });
  alert.show();

打开类似对话框并在Manifest.xml文件中注册。使用类似对话框。

public class WebDialog extends Dialog
{
