fragment嵌套webview问题总结

webview内部返回

webview.setOnKeyListener(new View.OnKeyListener() {
    @Override
    public boolean onKey(View view, int i, KeyEvent keyEvent) {

        //这里处理返回键事件
        if (nativeWeb.canGoBack()) {
            nativeWeb.goBack();
            Toast.makeText(getActivity(), "ok", Toast.LENGTH_SHORT).show();
            return true;
        }
        return false;
    }
});
