Java 使一个布局在另一个视图/布局开关上仍然可见

我有两个XML布局，例如“菜单布局”和“游戏布局”。在应用程序启动时，通过setContentView（R.id.menu_布局）将视图设置为“menu_布局”。就在这一行之后，我正在创建另一个布局-“top_layout”，我需要使它始终位于顶部（保持可见），而不考虑视图切换

这意味着，当视图从“菜单布局”切换到“游戏布局”或从“游戏布局”切换到“菜单布局”时，“顶部布局”仍然可见，并且不受此影响

知道如何使用这些参数创建“top_布局”吗

感谢您的建议。

您可以使用具有顶部布局的单个活动，然后在下面的容器中使用FragmentManager切换片段

使用从容器中动态添加和删除的视图可以手动实现类似的结果，当您需要处理具有多个替换视图的更复杂场景时，片段会更有用，并且还需要进行回栈，而您不想自己这样做

布局：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">
<include layout="@+id/top_layout" />

<FrameLayout
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"/>

public static class GameFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    return inflater.inflate(R.layout.game_layout, container, false);
}

FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
     MenuFragment fragment = new MenuFragment();
        fragmentTransaction.add(R.id.container, fragment);
        fragmentTransaction.commit();

FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    GameFragment fragment = new GameFragment();
    fragmentTransaction.replace(R.id.container, fragment);
    fragmentTransaction.commit();

}

片段添加：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">
<include layout="@+id/top_layout" />

<FrameLayout
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"/>

public static class GameFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    return inflater.inflate(R.layout.game_layout, container, false);
}

FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
     MenuFragment fragment = new MenuFragment();
        fragmentTransaction.add(R.id.container, fragment);
        fragmentTransaction.commit();

FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    GameFragment fragment = new GameFragment();
    fragmentTransaction.replace(R.id.container, fragment);
    fragmentTransaction.commit();

片段开关：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">
<include layout="@+id/top_layout" />

<FrameLayout
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"/>

public static class GameFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    return inflater.inflate(R.layout.game_layout, container, false);
}

FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
     MenuFragment fragment = new MenuFragment();
        fragmentTransaction.add(R.id.container, fragment);
        fragmentTransaction.commit();

FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    GameFragment fragment = new GameFragment();
    fragmentTransaction.replace(R.id.container, fragment);
    fragmentTransaction.commit();
