Question

我是材料设计的新手，滚动列表时我无法隐藏工具栏。有关我共享代码的更多信息，请参阅以下内容：

1.应用程序的常见布局

$_['text_dimensions'] = 'Dimensions:';
        $_['text_by'] = 'x';

2.运行此布局的运行时间：

请帮我找出解决方法。我遇到了这个问题，我不知道这段代码有什么问题。

Answer 1

添加：

app:layout_behavior="@string/appbar_scrolling_view_behavior"

到您的RecyclerView标签和片段的根标签。

Answer 2

你可以做这样的事情

public abstract class HidingScrollListener extends RecyclerView.OnScrollListener {
private static final int HIDE_THRESHOLD = 20;
private int scrolledDistance = 0;
private boolean controlsVisible = true;

@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);

if (scrolledDistance > HIDE_THRESHOLD && controlsVisible) {
  onHide();
  controlsVisible = false;
  scrolledDistance = 0;
} else if (scrolledDistance < -HIDE_THRESHOLD && !controlsVisible) {
  onShow();
  controlsVisible = true;
  scrolledDistance = 0;
}

if((controlsVisible && dy>0) || (!controlsVisible && dy<0)) {
  scrolledDistance += dy;
}
}

public abstract void onHide();
public abstract void onShow();

}

然后将此监听器添加到您的RecyclerView

recyclerView.setOnScrollListener(new HidingScrollListener() {
@Override
public void onHide() {
  hideViews();
}
@Override
public void onShow() {
  showViews();
}
});

在hideViews()方法中，您可以隐藏工具栏 mToolbar.animate().translationY(-mToolbar.getHeight()).setInterpolator(new AccelerateInterpolator(2));

在showViews()方法中，您可以显示工具栏 mToolbar.animate().translationY(0).setInterpolator(new DecelerateInterpolator(2));

Answer 3

如果你想使用它：

app:layout_behavior="@string/appbar_scrolling_view_behavior"

要滚动工具栏，请重新设计您的布局。

layout_behavior仅在AppBarLayout

下属于CoordinatorLayout时有效像这样：

<android.support.design.widget.CoordinatorLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@android:color/background_light">

            <android.support.design.widget.AppBarLayout
                   android:id="@+id/appbar"
                   android:layout_width="match_parent"
                   android:layout_height="wrap_content"
                   android:fitsSystemWindows="true"
                   android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
            </android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>

Answer 4

在R＆amp; D之后我发现AppBarLayout必须是CoordinatorLayout的直接孩子所以我的更正代码如下所示

series: [{
        name: 'On Track',
        data: [80,67,'']
}]

滚动recyclerview时隐藏工具栏
