call "shouldOverrideUrlLoading" method on webview.goBack()
I'm loading all my pages inside shouldOverrideUrlLoading
method on webview
(mainly to track the current page url and do some modificatio开发者_运维百科ns).
My problem is that the back button ( eg: webview.goback()
method ) bypasses the above function.
Is there any way i can explicitly call both the goback()
and shouldOverrideUrlLoading()
methods.
public boolean shouldOverrideUrlLoading(WebView view, String url){
//get current url and do some modifications to html}
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && web1.canGoBack()) {
webview.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
Looking at your code seems like once the shouldOverrideUrlLoading
method is called based on some logic for a specific URL Action you need the Webview
go back method. I would suggest you to use the following method inside the activity:
@Override
public void onBackPressed() {
if ((keyCode == KeyEvent.KEYCODE_BACK) && web1.canGoBack()) {
webview.goBack();
} else {
super.onBackPressed();
}
}
which does exactly the same as onKeypressed. (Used onBackPressed
instead of onKeypressed
but write this code inside the Activity class but not inside the custom WebViewClient
.
Call the onBackPressed()
inside your shouldOverrideUrlLoading
. Try this, should work.
