Question

我创建了简单的导航抽屉但是当我遇到像图像中的导航抽屉时，我被卡住了。我不知道如何实现这种功能。

enter image description here

在此图片中，“城市”是导航抽屉的项目，当我点击城市时，它会打开与其相邻的列表。

以下是完整的代码，因为我不知道细节可能无法满足您的要求：

首先我想展示demo：

enter image description here

string.xml：

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <string name="app_name">NavigationDrawer</string>
    <string name="hello_world">Hello world!</string>
    <string name="action_settings">Settings</string>

    <string-array name="left">
        <item name="1">1</item>
        <item name="2">2</item>
        <item name="3">3</item>
    </string-array>


    <string-array name="right1">

        <item name="3*8">3*8</item>
        <item name="3*9">3*9</item>
    </string-array>

</resources>

和MainActivity.java

package com.example.navigationdrawer;

import java.util.Arrays;
import java.util.List;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

                if(arg2 == 0){

                    rightListStrings = getResources().getStringArray(R.array.right1);

                    List<String> stringList = Arrays.asList(rightListStrings);

                    List<String> stringList = Arrays.asList(rightListStrings);

                    rightList.setAdapter(new MayAdapter(MainActivity.this, android.R.layout.simple_list_item_1, stringList));
                    rightList.setVisibility(View.VISIBLE);

                }
            }

        });

        drawer.setDrawerListener(new DrawerListener() {

            @Override
            public void onDrawerStateChanged(int arg0) {
                // TODO Auto-generated method stub

            @Override

                // TODO Auto-generated method stub

            }

            @Override

    }

 class MayAdapter extends ArrayAdapter<String>{

        this.myList = myList;
    }    
 }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }



}

和布局：

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/drawer"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.navigationdrawer.MainActivity"
    tools:ignore="MergeRootFrame" >

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent" >

        <TextView
            android:layout_width="240dip"
            android:layout_height="match_parent"
            android:text="Hello" />
    </FrameLayout>

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="left"
        android:orientation="horizontal" >

        <ListView
            android:id="@+id/left_list"
            android:layout_width="120dip"
            android:layout_height="match_parent"
            android:background="#00FF00"
            android:divider="#FFFFFF"
            android:dividerHeight="2dp" >
        </ListView>

        <ListView
            android:id="@+id/right_list"
            android:layout_width="120dip"
            android:layout_height="match_parent"
            android:background="#FF0000"
            android:divider="#FFFFFF"
            android:dividerHeight="2dp" >
        </ListView>
    </LinearLayout>

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

在您的滑动菜单中，我认为您需要使用可扩展的列表视图。
This是您的参考。
