我的应用中有一个折叠Toolbar
。
我使用NavigationDrawer
并在具有不同片段的项目之间切换,同时替换FrameLayout
,并将工具栏留在应用中。
其中一个片段有一个标签布局
当我显示该片段时,它显示在Toolbar
下方,工具栏阴影与其重叠
我希望它与工具栏位于同一级别,并且看起来和行为类似于AppBarLayout
。
此外,我想在展开工具栏时使标签透明。
如何重新组织布局以便这样做?
这是我的Xml:

答案 1 :(得分:3)
当我显示该片段时,它显示在工具栏下方,工具栏阴影与其重叠。 我希望它与工具栏处于同一级别,并且看起来和行为类似于AppBarLayout。
为此提供与标签布局相同的高程,根据材料设计指南described here默认高程为4 dp。所以尝试给出标签布局高程
另外,我希望在扩展工具栏时使标签透明。
为此添加一个类似
的类public abstract class AppBarStateChangeListener implements AppBarLayout.OnOffsetChangedListener {
public enum State {
EXPANDED,
COLLAPSED,
IDLE
}
private State mCurrentState = State.IDLE;
@Override
public final void onOffsetChanged(AppBarLayout appBarLayout, int i) {
if (i == 0) {
if (mCurrentState != State.EXPANDED) {
onStateChanged(appBarLayout, State.EXPANDED);
}
mCurrentState = State.EXPANDED;
} else if (Math.abs(i) >= appBarLayout.getTotalScrollRange()) {
if (mCurrentState != State.COLLAPSED) {
onStateChanged(appBarLayout, State.COLLAPSED);
}
mCurrentState = State.COLLAPSED;
} else {
if (mCurrentState != State.IDLE) {
onStateChanged(appBarLayout, State.IDLE);
}
mCurrentState = State.IDLE;
}
}
public abstract void onStateChanged(AppBarLayout appBarLayout, State state);
}
然后在您的活动中使用它
appBarLayout.addOnOffsetChangedListener(new AppBarStateChangeListener() {
@Override
public void onStateChanged(AppBarLayout appBarLayout, State state) {
Log.d("STATE", state.name());
//if state is expanded then set your tab layout background to transparent
}
});

我有类似的问题。
我解决了删除ActionBar的elevation
,同时显示带有不需要的阴影的片段。
我在Activity中添加了这两个方法:
public void setToolbarElevation(){
if (Build.VERSION.SDK_INT >= 21){
if (toolbar!=null) {
toolbar.setElevation(getResources().getDimensionPixelSize(R.dimen.actionbar_elevation));
}
}
}
public void removeToolbarElevation(){
if (Build.VERSION.SDK_INT >= 21){
if (toolbar!=null) {
toolbar.setElevation(0);
}
}
}
因此,当您使用选项卡调用片段时,您将调用活动中的removeToolbarElevation()
,阴影将消失。
让我知道它是否适合你。

你已经完成了这个。正如我所说的Blog。
您需要的内容的组合意味着DrawerLayout
+ Fragments
+ CollapsingToolbarLayout
的组合。

然后,当我切换片段时,我只在我想要它们的片段上显示标签,并在我不希望它们显示时隐藏它们:
toolbar_layout.SetExpanded(true);
tabs.Visibility = ViewStates.Gone;
当我想向他们展示时:
toolbar_layout.SetExpanded(false,false);
tabs.Visibility = ViewStates.Visible;
虽然我没有让它们透明,但我决定在显示它们时折叠工具栏,并禁用使用标签在片段上展开它。
也许不是最好的解决方案,但它对我来说效果很好。
