问题:
I have a Collapsing Toolbar in my app.
I use a NavigationDrawer and switch between the items with different fragments, while replacing a FrameLayout, and leaving the Toolbar across the app.
One of the fragments has a tab layout.
When I show that fragment it is shown underneath the Toolbar, with the Toolbar shadow overlapping it.
I want it to be on the same level with the Toolbar, and to look and act like it is in the same AppBarLayout.
Also, I want to make the tabs transparent when the Toolbar is expanded.
How do I reorganize my layouts so that this will work?
Here is my Xml:

You should make a strucure like this
<?xml version="1.0" encoding="utf-8"?>

Taken from here
Also see this answer it explained well there.
If you want further explaination then read these blogs

回答2:
I had a similar problem.
I solved removing the elevation of the ActionBar while showing the fragment with the undesired shadow.
I added this two methods in the Activity:
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);
}
}
}
So when you call the fragment with the tabs, you call the removeToolbarElevation() in the activity and the shadow should disappear.
Let me know if it works for you.
回答3:
When I show that fragment it is shown underneath the Toolbar, with the Toolbar shadow overlapping it.
I want it to be on the same level with the Toolbar, and to look and act like it is in the same AppBarLayout.
for this give the same elevation to the tab layout as per the material design guidelines described here default elevation is 4 dp. so try giving the tab layout elevation
Also, I want to make the tabs transparent when the Toolbar is expanded.
for this add a class like this
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);
}
then in your activity use it like
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
}
});

You have go through this. As I am refering this Blog.
It is combination of what you have require means the combination of DrawerLayout + Fragments + CollapsingToolbarLayout.

</android.support.v4.widget.DrawerLayout>
Then, when I switch the fragments, I show the tabs only on the fragment that I want them in, and hide them when I don't want them to show:
toolbar_layout.SetExpanded(true);
tabs.Visibility = ViewStates.Gone;
And when I want to show them:
toolbar_layout.SetExpanded(false,false);
tabs.Visibility = ViewStates.Visible;
Although I don't get them transparent, but I decided to just collapse the toolbar when I show them, and disable expanding it on the fragment with the tabs.
Maybe not the best solution, but it works pretty well for me.
