Android fragments 新片段未完全替换旧片段

这是我点击我的图片按钮后的布局，新片段没有完全替换旧片段

这是我以前的片段菜单java代码

public class CMenu extends Fragment implements View.OnClickListener{
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup 
container, @Nullable Bundle savedInstanceState){

return inflater.inflate(R.layout.fragment_cmenu,container,false);
}

@Override
public void onViewCreated(View view,@Nullable Bundle savedInstanceState){
    super.onViewCreated(view,savedInstanceState);
    initView(view);

}
private void initView(View view){
    ImageButton prebtn = (ImageButton) view.findViewById(R.id.premium_cake);
    prebtn.setOnClickListener(this);
    ImageButton homemade = (ImageButton) view.findViewById(R.id.homemade);
    homemade.setOnClickListener(this);
    ImageButton sc_cake = (ImageButton) view.findViewById(R.id.sc_cake);
    sc_cake.setOnClickListener(this);
    ImageButton special_food = (ImageButton) 
    view.findViewById(R.id.special_food);
    special_food.setOnClickListener(this);
    ImageButton delicious_drink = (ImageButton) 
    view.findViewById(R.id.delicious_drink);
    delicious_drink.setOnClickListener(this);
    ImageButton other = (ImageButton) view.findViewById(R.id.other);
    other.setOnClickListener(this);

}

@Override
public void onClick(View view){
    switch (view.getId()){
        case R.id.premium_cake:

getFragmentManager().beginTransaction().replace(R.id.MenuFragment,new 
PremiumCake()).addToBackStack(null).commit();
            break;
        case R.id.homemade:

getFragmentManager().beginTransaction().replace(R.id.MenuFragment,new 
HomeMade()).addToBackStack(null).commit();
            break;
        case R.id.sc_cake:

getFragmentManager().beginTransaction().replace(R.id.MenuFragment,new 
SpecialCake()).addToBackStack(null).commit();
            break;
        case R.id.delicious_drink:

getFragmentManager().beginTransaction().replace(R.id.MenuFragment,new 
DeliciousDrink()).addToBackStack(null).commit();
            break;
        case R.id.special_food:

getFragmentManager().beginTransaction().replace(R.id.MenuFragment,new 
SignatureFood()).addToBackStack(null).commit();
            break;
        case R.id.other:

getFragmentManager().beginTransaction().replace(R.id.MenuFragment,new 
 Other()).addToBackStack(null).commit();
            break;
    }
}

this is my new fragment java code

public class Other extends Fragment {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}

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

旧片段xml（我正在使用滚动视图）

新片段xml

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true">

<GridLayout
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:weightSum="1"
    android:background="#2e3192">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="50dp">

        <Button
            android:id="@+id/cb_big"
            android:layout_width="0dp"
            android:layout_weight="1"
            android:layout_height="180dp"
            android:background="@drawable/coolerbag_big" />

        <Button
            android:id="@+id/cb_small"
            android:layout_width="0dp"
            android:layout_weight="1"
            android:layout_height="180dp"
            android:background="@drawable/coolerbag_small" />


    </LinearLayout>
</GridLayout>
</ScrollView>

包含旧片段的活动的XML

现在，单击图像时用新片段替换旧片段，而不是：

getFragmentManager().beginTransaction().replace(R.id.MenuFragment,new 
PremiumCake()).addToBackStack(null).commit();

只要做：

 getFragmentManager().beginTransaction().replace(R.id.container,new 
    PremiumCake()).addToBackStack(null).commit();

容器是活动的XML中的框架布局，它包含 您的旧片段并用新片段替换它

请输入您为替换碎片而编写的代码。很抱歉，这是我第一次在strackoverflow上发表文章。我在帖子中更新的代码是您将片段本身作为容器提供的，您需要包含片段的布局的id。我将上传下面的代码。很乐意帮助：）

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

getFragmentManager().beginTransaction().replace(R.id.MenuFragment,new 
PremiumCake()).addToBackStack(null).commit();

 getFragmentManager().beginTransaction().replace(R.id.container,new 
    PremiumCake()).addToBackStack(null).commit();
