Android工具栏上的所有活动

Question

I am new to Android. I need to define the tool bar to all the activity. For home screen I have some menu icons on toolbar.

For other activities I need to have back button on toolbar with some selected menu icons. (visible true and false).

What's the best approach ?

1. Define one toolbar and user it everywhere
2. Create toolbar every time for each activities.

When I create new activities I don't want to create toolbar every time. What's the best way to have activities in inheritance way. (define toolbar once and use it everywhere on activity screen)?

Answer 1

Create a layout named toobar.xml

 <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
          />

Then include this in every activity layout file:

<include layout="@layout/toolbar" />

Then initiate in onCreate() of every activity:

 Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
 setSupportActionBar(toolbar);

Create theme to remove default ActionBar:

<style name="AppTheme.NoActionBar">
     <item name="windowActionBar">false</item>
     <item name="windowNoTitle">true</item>
 </style>

Set theme in manifest:

   <activity
      android:name=".MainActivity"
      android:label="@string/app_name"
      android:theme="@style/AppTheme.NoActionBar" />

Hope this helps.

创建工具栏并将其与片段配合使用，这是最简单的方法

Answer 3

You can use BaseActivity pattern. With it you can define toolbar in base and extend that in all other activities. or you can change fragments at bottom part of toolbar using frame layout.
