Navdraweritem

public class NavDrawerItem {

    private String title;
    private int icon;
    private String count = "0";
    // boolean to set visiblity of the counter
    private boolean isCounterVisible = false;

    public NavDrawerItem(){}

    public NavDrawerItem(String title, int icon){
        this.title = title;
        this.icon = icon;
    }

    public NavDrawerItem(String title, int icon, boolean isCounterVisible, String count){
        this.title = title;
        this.icon = icon;
        this.isCounterVisible = isCounterVisible;
        this.count = count;
    }

    public String getTitle(){
        return this.title;
    }

    public int getIcon(){
        return this.icon;
    }

    public String getCount(){
        return this.count;
    }

    public boolean getCounterVisibility(){
        return this.isCounterVisible;
    }

    public void setTitle(String title){
        this.title = title;
    }

    public void setIcon(int icon){
        this.icon = icon;
    }

    public void setCount(String count){
        this.count = count;
    }

    public void setCounterVisibility(boolean isCounterVisible){
        this.isCounterVisible = isCounterVisible;
    }
}

点击后未打开的个人资料（侧边菜单的第1个内容）。

public class Profile extends Fragment {

    public Profile(){}

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.profile, container, false);

        return rootView;
    }
}

是profile.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:id="@+id/txtLabel"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:textSize="16dp"
        android:text="Profile"/>
</RelativeLayout>

Answer 1

好的，您的问题将得到解决here 您应该添加以下行：

mDrawerList.bringToFront();
mDrawerLayout.requestLayout();

另请注意，SlideMenuClickListener应实施AdapterView.OnItemClickListener，而不是ListView.OnItemClickListener。

将来，请考虑使用NavigationView代替它 - 它也可以高度自定义，而且对我来说也更容易。

更新。当您使用支持抽屉时，请尝试

android.support.v4.app.Fragment;
android.support.v4.app.FragmentManager;

然后使用getSupportFragmentManager（）我相信它应该有用。

Update2。尝试here：
从主要布局中移除ListView @+id/list，只留下frame_container和list_slidermenu。

<强> UPDATE3。为片段制作xml：

<?xml version="1.0" encoding="utf-8"?>
    <ListView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/list"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    </ListView>

为片段制作课程：

public class NewFragment extends Fragment {

    public NewFragment (){}

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.new_fragment, container, false);
        ListView list = (Listview) rootView.findViewById(R.id.list);
//then do what you need with this list
        return rootView;
    }
}

在MainActivity中，用NewFragment的实例替换容器。

Answer 2

activity_main.xml应该是这样的由于Framelayout标签是一个容器，必须包含json数据列表视图

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context=".MainActivity"
        android:id="@+id/app_name"
        >
       <FrameLayout
            android:id="@+id/frame_container"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">
            <ListView
                android:id="@+id/list"
                android:layout_width="wrap_content"
                android:layout_height="match_parent"
                android:divider="@color/list_divider"
                android:dividerHeight="1dp"
                android:listSelector="@drawable/list_row_selector"
                android:background="@color/list_background"/>
        </FrameLayout>

        <android.support.v4.widget.DrawerLayout
            android:id="@+id/drawerLayout"
            android:layout_width="match_parent"
            android:layout_height="match_parent"

            >
        <ListView
            android:id="@+id/list_slidermenu"
            android:layout_width="240dp"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            android:choiceMode="singleChoice"
            android:divider="@color/list_divider"
            android:dividerHeight="1dp"
            android:listSelector="@drawable/list_selector"
            android:background="@color/list_background"/>

        </android.support.v4.widget.DrawerLayout>
