Display HttpResponse (string from Handler) in new WebView

Question

I have the following code in a form's submit button onClickListener:

String action, user, pwd, user_field, pwd_field;

        action = "theURL";

        user_field = "id";
        pwd_field = "pw";
        user = "username";
        pwd = "password!!";

        List<NameValuePair> myList = new ArrayList<NameValuePair>();
        myList.add(new BasicNameValuePair(user_field, user)); 
        myList.add(new BasicNameValuePair(pwd_field, pwd));

        HttpParams params = new BasicHttpParams();
        HttpClient client = new DefaultHttpClient(params);
        HttpPost post = new HttpPost(action);
        HttpResponse end = null;
        String endResult = null;

        try {
            post.setEntity(new UrlEncodedFormEntity(myList));
        } catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } 

        try {
            HttpResponse response = client.execute(post);
            end = response;
        } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }  


        BasicResponseHandler myHandler = new BasicResponseHandler();

        try {
            endResult = myHandler.handleResponse(end);
        } catch (HttpResponseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

How can I take the resulting string (endResult) and start a new activity using an intent that will open webview and load the html?

Answer 1

You can start a new intent with

Intent myWebViewIntent = new Intent(context, MyWebViewActivity.class);
myWebViewIntent.putExtra('htmlString', endResult);
context.startActivity(myWebViewIntent);

Then in your MyWebViewActivity class you would have something like:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.my_view_that_contains_a_webview);
    WebView webview = (WebView)findViewById(R.id.my_webview);

    Bundle extras = getIntent().getExtras();
    if(extras != null) {

         // Get endResult
         String htmlString = extras.getString('htmlString', '');
         webview.loadData(htmlString, "text/html", "utf-8");

    }
}

Answer 2

The resulting code after applying the above answer is as follows:

Intent myWebViewIntent = new Intent(YourAppClassHere.this, YourWebViewClassHere.class);
myWebViewIntent.putExtra("htmlString", theStringThatHoldsTheHTML);
startActivity(myWebViewIntent);

The full code for a basic webview class that I used was:

public class MyWebView extends android.app.Activity{

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

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

    Bundle extras = getIntent().getExtras();
    if(extras != null) {

         // Get endResult
         String htmlString = extras.getString("htmlString");
         webview.loadDataWithBaseURL(null, htmlString, "text/html", "utf-8", null);
    }

   }
}

It's also worth noting that this, for me anyway, crashed the program every time until I added the following lines to the AndroidManifest.xml:

<activity android:name=".MyWebView">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

Hopefully that'll help somebody else out in the future :) Thanks to disretrospect.
