        web.loadUrl(url);


        mWebView.getSettings().setJavaScriptEnabled(true);

        mWebView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
        mWebView.getSettings().setSavePassword(true);
        mWebView.getSettings().setSupportZoom(true);
        mWebView.getSettings().setSaveFormData(true);
        mWebView.getSettings().setSupportZoom(false);
        mWebView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);

            public void onBackPressed() {
                if(mWebView.canGoBack())
                {
                    mWebView.goBack();

                else
                {

                }
            }

            public boolean shouldOverrideUrlLoading(WebView view, String url) {

                return true;
            }
        });

尝试以下代码..

@Override
public void onBackPressed() {
    if (mWebView.canGoBack()) {
        mWebView.goBack();
        return;
    }
    super.onBackPressed();
}
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
    return false;
}
