我可以分别为每个片段设置工具栏吗？ 如何处理导航抽屉

Question

In my app some pages have custom view in toolbar. Some fragment have transparent toolbar and some have coordinate layout scroll.

So I have decided to have toolbar separate for each fragment I want to know is it a good practice or not.

If someone has already done this please share code or example.

You can use custom toolbars in your fragments. and you have to implement them separately for each fragment. First of all declare your toolbar in your fragment layout :

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:tools="http://schemas.android.com/tools"
            xmlns:app="http://schemas.android.com/apk/res-auto"
            android:id="@+id/activity_main"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@color/white"
            >
<android.support.v7.widget.Toolbar
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/colorPrimaryDark"
    android:gravity="start"
    android:minHeight="?attr/actionBarSize"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    >

    <RelativeLayout
       // your custom toolbar layout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
    </RelativeLayout>


</android.support.v7.widget.Toolbar>

Then implement it in your fragment:

find it in fragment:

 @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle 
    savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment, container, false);
        Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);

        //set toolbar appearance
        toolbar.setBackground(your background);

        //for create home button
        AppCompatActivity activity = (AppCompatActivity) getActivity();
        activity.setSupportActionBar(toolbar);
        activity.getSupportActionBar().setDisplayHomeAsUpEnabled(true);

  return view;
}

And yes you can implement click listeners and whatever you want to do with your toolbar. For more take a look at the second answer: How to get custom toolbar
