Android-从膨胀的布局中查找视图的ID

Question

I know there are lots of other answers on stackoverflow on the same thing but I can't seem to get it to work.

What I'm trying to do is find the ID of a view from an inflated layout. I want WV1 to load google.com when the button is clicked, you can see I'm using onClick from XML to do this.

public void ButtonClicked(View view)
        { 

        View inflatedView = getLayoutInflater().inflate(R.layout.tab_content, null);
        WV1 = (WebView) inflatedView.findViewById(R.id.tab1WV);
        WV1.setWebViewClient(new InsideWebViewClient());

          if (WV1.isShown()) {
                WV1.requestFocus();
                    }
                else{
                }

          if (WV1.isFocused()) {
                WV1.loadUrl("http://www.google.com"); 
                }
        }

This is in the MainActivity, the webview (WV1) is in the other, inflated class.

Problem is, nothing happens at all...

I've been stuck on this for quite some time now, I appreciate all help given to me.. If there's any other information you require then just ask, thanks in advance!

--Edit-- In the MainActivity, theres tabhost and a button that creates new tabs. When new tabs are created the MainActivity inflates the second class file containing the webview, I can't get the mainactivity to find the webview from the inflated class. I dont know if this helps any more or not...

Answer 1

You're not attaching it to anything. You need to either supply the parent when you inflate it, or call addView on the ViewGroup that should contain it.

public void ButtonClicked(View view){ 

    View inflatedView = getLayoutInflater().inflate(R.layout.tab_content, (ViewGroup) findViewById(android.R.id.content));
    WV1 = (WebView) inflatedView.findViewById(R.id.tab1WV);
    WV1.setWebViewClient(new InsideWebViewClient());

    if (WV1.isShown()) {
        WV1.requestFocus();
    }

     if (WV1.isFocused()) {
         WV1.loadUrl("http://www.google.com"); 
    }
}

Or:

((ViewGroup)findViewById(android.R.id.content)).addChild(WV1);

Both of these will add your view at the end. You may need to add some layout attributes to get it to look like you want.

Check out this link:

Android - Add textview to layout when button is pressed

Where one of the answers does this: mLayout.addView(createNewTextView(mEditText.getText().toString()));

where mLayout is a linear layout in the activity.

You'd have to add a view to one of your current layouts or start up an activity that opens up with a web view in it.

Alternative way to create webview :

Webview WV1 = new WebView(view.getContext);
WV1.setWebViewClient(new InsideWebViewClient());

  if (WV1.isShown()) {
        WV1.requestFocus();
            }
        else{
        }

  if (WV1.isFocused()) {
        WV1.loadUrl("http://www.google.com"); 
        }
}

Now add this to a view group

viewgroup.addchild(WV1);
