我在TabLayout
和AppBarLayout
上遇到问题,因为我希望我的标签位于底部,而现在它们位于顶部,所以当我向上滚动时它们与图像一起隐藏。还有第二个问题-当我滚动文本时,AppBarLayout
的图像不会隐藏,而当我尝试顶部的scroll
图像时,它只会隐藏/显示

滚动视图不支持Appbar行为,将其更改为NestedScrollView并使用以下布局:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<android.support.design.widget.TabLayout
android:id="@+id/sliding_tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
<android.support.v4.view.ViewPager
android:id="@+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout

尝试像这样向您的 <android.support.design.widget.TabLayout
android:id="@+id/sliding_tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
/>
添加重力:
<android.support.v4.view.ViewPager
android:id="@+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<android.support.design.widget.TabLayout
android:id="@+id/sliding_tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
</android.support.v4.view.ViewPager>
修改: 为了使TabLayout位于CollapsingToolbarLayout下面,只需将其放入ViewPager中,就像这样:
"python.linting.pep8Args": ["--max-line-length=100"],

请将您的代码更改为此:
new GameClock(this).start();
现在要在滚动文本时隐藏图像,请将此行添加到View thats滚动中(我假设您只是在此处使用了textView和滚动条):
