我有一个应用程序，它是从 Android 手机的联系人列表中检索到的联系人姓名列表。
我试图添加TextView，它就像ListView上方的标题和TextView下方的Button。TextView 和 Button 在列表中的每个名称下方重复出现。看起来像这样

带有标题和按钮的名称的 ListView

不仅如此，文本视图在列表上方，按钮也在列表下方。这很奇怪。我不确定如何使列表上方的 TextView 和按钮仅位于列表下方。

哦，是的，请看一下我的 java 和 xml 布局代码，谢谢
——contacts_list.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:background="@color/light_goldenrod"

       style="@style/ButtonText"
       android:text="Main Menu" />

</LinearLayout>

联系人列表.java

public class ContactsList extends ListActivity
{
    TextView contactName;
    ListView list;

    final Context context = this;   
    Cursor cursor;
    BuddyDBAdapter buddyDB = new BuddyDBAdapter(this);

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);     
        setContentView(R.layout.contacts_list);

        list = (ListView) findViewById(android.R.id.list);

        Uri allContacts = Uri.parse("content://contacts/people");

        Cursor c = managedQuery(allContacts, null, null, null, null);

        String[] columns = new String[] {ContactsContract.Contacts.DISPLAY_NAME};
        int[] views = new int[]  {R.id.contactName};

        startManagingCursor(c);

        SimpleCursorAdapter friendsAdapter = new SimpleCursorAdapter(this, R.layout.contacts_list, c, columns, views);
        this.setListAdapter(friendsAdapter);
    }

    @Override
    public void onListItemClick(ListView l, View v, int position, long id)
    {
        buddyDB.open();
        long name_id;
        super.onListItemClick(l, v, position, id);

           Cursor cursor = null;

           cursor = (Cursor) l.getItemAtPosition(position);
           Intent intent = new Intent(ContactsList.this, Create_Events.class);
           intent.putExtra("name", cursor.getString(cursor.getColumnIndex(buddyDB.KEY_NAME)));
           startActivity(intent);

        Cursor c = ((SimpleCursorAdapter)l.getAdapter()).getCursor();
        c.moveToPosition(position);

        TextView contactName = (TextView) v.findViewById(R.id.contactName);
        String NameValue = contactName.getText().toString();        
        name_id = buddyDB.insertNames(NameValue);

        buddyDB.close();    
    } 
}

请帮我解决一下这个。
提供的任何帮助将不胜感激。谢谢 =)

如下创建一个布局文件并将其命名为contacts_item.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:background="@color/light_goldenrod"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
   <TextView
        android:textColor="@color/dark_purple"
        android:id="@+id/contactName"
        android:textStyle="bold"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</LinearLayout>

更改以下内容：

SimpleCursorAdapter friendsAdapter = new SimpleCursorAdapter(this, R.layout.contacts_list, c, columns, views);

至：

SimpleCursorAdapter friendsAdapter = new SimpleCursorAdapter(this, R.layout.contacts_item, c, columns, views);
