WebView无法在软键上滚动

Question

当用户按下WebView中的某个字段时，我试图使布局向上滚动（当前键盘覆盖该字段）。我的布局文件如下：

            </WebView>



        </android.support.v4.widget.NestedScrollView>

</android.support.design.widget.CoordinatorLayout>

我尝试了以下方法-但无济于事：

1. 在onCreate上添加以下内容：getWindow（）。setSoftInputMode（WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE）;

2. 在清单中的“活动”中添加以下内容：android：windowSoftInputMode =“ stateHidden | adjustPan”和android：windowSoftInputMode =“ stateHidden | adjustResize”

有解决方案吗？
