android - 在应用程序的所有 Activity 中重用 Action Bar

Question

我创建了一个 MenuActivity，它有一个 Action Bar 和一个 Split Action Bar。我想将此操作栏和拆分操作栏 View 用于我的应用程序中的所有 Activity 。我是 android 的新手，所以有人可以逐步指导我。

我还试图将搜索图标放在现在出现在 SplitActionBar 上的操作栏上。我在 SplitActionBar 上有四个图标，我想在操作栏上而不是在 SplitActionBar 上显示搜索图标。搜索图标是一个 SearchView 项，单击它会在 ActionBar 上展开，这非常不整洁。我希望它出现在 ActionBar 中最右边的位置，并在单击时在同一位置展开。

这是 MenuACtivity.java:

Answer 1

创建实现action bar 的BaseActivity。并且你所有的 Activity 都必须继承BaseActivity(不是Activity)

public class BaseActiivity extends Activity{
     @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
       // action bar implementation
    }

}

public class MainActivity extends BaseAcivity{
    //your code
}
