I have one Edit Text, 5 buttons and a Webview. Webview load url when user type url in edit text and tap Go button or hit Enter on soft keyboard. I have three problems here.
1-WebView loads website for example "www.google.com" but soft keyboard does not hide itself. I want to hide it like other browser do.
2-When user open a specific url and then try to remove it from Edit Text to open a different url, webview start loading that incomplete url and get focus automatically on every letter removing. For example user loads "www.google.com" then he try to remove url from end and as he remove "m", webview try to load "www.google.co" then edit text is out of focus and webview stole focus from it then user have to tap in edit text again to remove url but it tries to load after every letter removing. I need Webview to load url only when user tap on Go button or hit Enter on soft keyboard.
Update (forgot to add third problem, here it is)
3-Where can i check when WebView CanGoBack and CanGoForward because i want to set visibility of Back and Forward buttons to false at startup and enabled these two buttons while they CanGoBack and CanGoForward. Where should i put my piece of code to check these conditions?
I hope you guys can understand what i am trying to say. Sorry for my poor english.

}
load();
return false;
}
});
}
@Override

}
}
public void load(){
url = etUrl.getText().toString();
if (!url.startsWith("http://")) {
url = "http://" + url;
}
try {
wb.loadUrl(url);
wb.requestFocus();
} catch (Exception e) {
Toast.makeText(getApplicationContext(), " " + e, Toast.LENGTH_LONG).show();
