我正在创建和应用程序，其中有 thre 节点（描述、内容、营养），就像这张图片http://imgur.com/TmJT6GI 当用户单击任何节点时，它将展开并在其中显示另一个屏幕我将如何做到这一点？我会看到有可用的消耗性列表视图，但它在每个节点上显示单个列表，例如这个例子http://ranfeng0610.blog.163.com/blog/static/1857082842011727111359969/是在每个节点中消耗列表视图，我撒谎以在到达时扩展布局节点 al 节点显示不同的布局用户界面）我将如何制作这样的屏幕？请帮助我，你有什么想法吗？？？？

           1、main.xml
 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<!-- 禁用系统自带图标android:groupIndicator="@null" -->
<ExpandableListView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:groupIndicator="@null"
android:id="@+id/mExpandableListView"
/>
</LinearLayout>
 2、group.xml

  <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout
 xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation = "horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView
android:layout_width = "25dip"
android:layout_height = "25dip"
android:layout_marginTop="10dip"
android:id="@+id/mImageView"
/>
 <TextView
android:id = "@+id/group_tv"
android:layout_width = "wrap_content"
android:layout_height = "wrap_content"
android:paddingLeft = "30px"
android:paddingBottom = "10px"
android:textSize = "26sp"/>
</LinearLayout>
3、child.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation = "horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
 android:layout_gravity = "center_vertical"
 android:id = "@+id/child_iv"
 android:layout_width = "70px"
 android:layout_height = "70px"
 android:paddingLeft = "30px"
 android:paddingTop = "2px"
 android:paddingBottom = "5px"
 android:src = "@drawable/icon"/>
 <TextView
  android:layout_gravity = "center_vertical"
 android:id = "@+id/child_tv"
 android:layout_width = "fill_parent"
 android:layout_height = "fill_parent"
 android:paddingLeft = "30px"
  android:paddingTop = "10px"
 android:paddingBottom = "5px"
 android:textSize = "30sp"/>
 </LinearLayout>

你可以在不使用可扩展列表视图的情况下实现它。你只需控制视图的可见性。

主要活动

boolean flag;
boolean flag2;
LinearLayout llContains;
LinearLayout llContents;
LinearLayout llContains2;
LinearLayout llContents2;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


     llContains = (LinearLayout)findViewById(R.id.llContains);
     llContents = (LinearLayout)findViewById(R.id.llContents);
     llContains2 = (LinearLayout)findViewById(R.id.llContains2);
     llContents2 = (LinearLayout)findViewById(R.id.llContents2);

     llContains.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) 
        {
            if(!flag)
            {
                llContents.setVisibility(View.VISIBLE);
                flag = true;
            }
            else
            {
                llContents.setVisibility(View.GONE);
                flag = false;
            }

        }
    });

    llContains2.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) 
        {
            if(!flag2)
            {
                llContents2.setVisibility(View.VISIBLE);
                flag2 = true;
            }
            else
            {
                llContents2.setVisibility(View.GONE);
                flag2 = false;
            }

        }
    });


}
