我可以分别为每个片段设置工具栏吗?如何处理导航抽屉 [英] Can I have toolbar for each fragment separately. How to handle navigation drawer

问题描述

在我的应用中，某些页面在工具栏中具有自定义视图.有些片段具有透明的工具栏，有些具有坐标布局滚动.

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

所以我决定为我想知道的每个片段单独设置工具栏.

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

如果有人已经这样做，请分享代码或示例.

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

推荐答案

您可以在片段中使用自定义工具栏.并且您必须为每个片段分别实现它们.首先在片段布局中声明工具栏:

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>

然后在您的片段中实现它:

Then implement it in your fragment:

在片段中找到它:

 @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;
}

是的，您可以实现单击侦听器以及您想对工具栏执行的任何操作.有关更多信息，请查看第二个答案: 如何获取自定义工具栏
