I have a WebView that I would like to expand to fullscreen. The user will interact with it, so it needs to maintain some sort of state when it expands. The ideal process is this:
- Remove WebView from its parent
- Put WebView at the top of the current View hierarchy with `FILL_PARENT` for width and height
Later, I will need the put the WebView back:
- Remove WebView from top of the hierarchy
- Restore the old hierarchy
- Put WebView back where it was with its previous setting for width and height
I know about getRootView, but I don't know how to use it. What's a DecorView?
If anyone has some sample code to accomplish the expanding and collapsing behavior I've described above, I'd be really grateful. Thanks!
Get the root view of the DecorView:
ViewGroup parentViewGroup = (ViewGroup) webView.getRootView().findViewById(android.R.id.content);
View rootview = parentViewGroup.getChildAt(0);
Remove that root view:
parentViewGroup.removeViewAt(0);
Remove the WebView from its parent:
View webViewParent = (View) webView.getParent();
webViewParent.removeView(webView);
Put the WebView at the top of the view hierarchy:
parentViewGroup.addView(webView, 0, new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout.LayoutParams.FILL_PARENT));
Use your rootview reference to undo the expansion.
The only thing is: I don't know how you're going to restore the layout parameters for rootview.
