android - 当EditText获得焦点时CollapsingToolbarLayout不塌陷

我在CollapsingToolBar中使用了CoordinatorLayout，并且我已经将NestScrollView包含一些EditText作为 subview 。我所面对的是，当edittext变得聚焦并且键盘提示出现时，我的完整 View 没有向上滚动。

下面是该布局输出的代码和图像。

<android.support.design.widget.AppBarLayout
    android:id="@+id/appbar"
    android:layout_width="match_parent"
    android:layout_height="@dimen/app_bar_height"

    <android.support.design.widget.CollapsingToolbarLayout

最佳答案

我已通过将OnFocusChangeListener添加到EditText以及是否具有焦点来解决此问题-只需使用setExpanded方法折叠 View 即可:

editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(final View v, boolean hasFocus) {
        if (hasFocus) {
           mAppBarLayout.setExpanded(false, true);
        }
    }
});

如果您希望每次布局中的其他CollapsingToolbarLayout都集中时折叠EditText，则应该为它们中的每一个设置相同的OnFocusChangeListener。
