Как показать несколько элементов в виде списка

Question

Мой код просто показывает имя человека в списке View.I хочу показать номер, а также в представлении «Список».

активность

public class HomeActivity extends Activity { 
    List<String> names; 
    //List<integer> time; 
    List<Integer> number; 
    int position; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_home); 
     // textView = (TextView) findViewById(R.id.listView); 
     getCallDetails(); 
    } 
    private void getCallDetails() { 


     names = new ArrayList<String>(); 
     number = new ArrayList<Integer>(); 

     StringBuffer sb = new StringBuffer(); 
     String strOrder = android.provider.CallLog.Calls.DATE + " DESC"; 
    /* Query the CallLog Content Provider */ 
     Cursor managedCursor = managedQuery(CallLog.Calls.CONTENT_URI, null, 
       null, null, strOrder); 
     int name = managedCursor.getColumnIndex(CallLog.Calls.CACHED_NAME); 
     int number = managedCursor.getColumnIndex(CallLog.Calls.NUMBER); 
     int type = managedCursor.getColumnIndex(CallLog.Calls.TYPE); 
     int date = managedCursor.getColumnIndex(CallLog.Calls.DATE); 
     int duration = managedCursor.getColumnIndex(CallLog.Calls.DURATION); 
     //sb.append("Call Log :"); 
     while (managedCursor.moveToNext()) { 
      String namee = managedCursor.getString(name); 
      String phNum = managedCursor.getString(number); 
      String callTypeCode = managedCursor.getString(type); 
      String strcallDate = managedCursor.getString(date); 
      Date callDate = new Date(Long.valueOf(strcallDate)); 
      String callDuration = managedCursor.getString(duration); 
      String callType = null; 
      int callcode = Integer.parseInt(callTypeCode); 
      names.add(namee); 
      // number.add(phNum); 


      switch (callcode) { 
       case CallLog.Calls.OUTGOING_TYPE: 
        callType = "Outgoing"; 
        break; 
       case CallLog.Calls.INCOMING_TYPE: 
        callType = "Incoming"; 
        break; 
       case CallLog.Calls.MISSED_TYPE: 
        callType = "Missed"; 
        break; 
     } 
      // adaptorname adaptor = new adaptorname(this, names); 
      //adaptorname adaptor = new adaptorname(this, names); 

      /* adaptorname adaptor = new SimpleCursorAdapter(this, R.layout.cell, managedCursor, 
        adaptorname adaptor= new adaptorname[]{this,names,number}, new int[]{ 
       R.id.lblName, R.id.lblnum});*/ 


      adaptorname adaptor = new adaptorname(this, names); 

      ListView list = (ListView) findViewById(R.id.listView); 
      list.setAdapter(adaptor); 


} 
} 
} 

Этот обычай адаптер я использую

адаптер

import android.content.Context; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.BaseAdapter; 
import android.widget.TextView; 

import java.util.List; 

/** 
* 
*/ 
public class adaptorname extends BaseAdapter { 

    List<String> name; 
    //my addition 
    List<String> numbers; 
    Context context; 

    adaptorname(Context context, List<String> name,List<String> numbers){ 

     this.name = name; 

     this.numbers=numbers; 
     this.context = context; 
    } 


    @Override 
    public int getCount() { 
     return name.size(); 
    } 

    @Override 
    public Object getItem(int position) { 
     return name.get(position); 
    } 

    @Override 
    public long getItemId(int position) { 
     return position; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 


//  // Get the data item for this position 
     // CellName cellNsme = new CellName(); 


     // Check if an existing view is being reused, otherwise inflate the view 
     ViewHolder viewHolder; // view lookup cache stored in tag 
     if (convertView == null) { 
      viewHolder = new ViewHolder(); 
      LayoutInflater inflater = LayoutInflater.from(context); 
      convertView = inflater.inflate(R.layout.cell, parent, false); 
      viewHolder.name = (TextView) convertView.findViewById(R.id.lblName); 
      //my addition 
       viewHolder.number=(TextView) convertView.findViewById(R.id.lblnum); 
      convertView.setTag(viewHolder); 
     } else { 
      viewHolder = (ViewHolder) convertView.getTag(); 
     } 
     // Populate the data into the template view using the data object 
     viewHolder.name.setText(name.get(position)); 
     //my addition 
     //viewHolder.number.setText(numbers.get(position)); 


     // Return the completed view to render on screen 
     return convertView; 




    } 


    public class ViewHolder{ 

     TextView name; 
     TextView number; 
    } 
} 

Это представление списка Layout

Layout

<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="com.example.moni.friendrecco.Call_Reports"> 



    < 

ListView 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:id="@+id/listView" 
      android:layout_centerVertical="true" 
      android:layout_centerHorizontal="true" /> 
    </RelativeLayout> 

это макет для моей строки

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" android:layout_width="match_parent" 
    android:layout_height="130dp" 
    android:background="#5ffff7"> 

    <TextView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="lblName" 
     android:id="@+id/lblName" 
     android:layout_centerVertical="true" 
     android:layout_alignParentLeft="true" 
     android:layout_alignParentStart="true" 
     android:textSize="30dp" /> 

    <TextView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="lblnum" 
     android:id="@+id/lblnum" 
     android:layout_alignParentBottom="true" 
     android:layout_alignParentLeft="true" 
     android:layout_alignParentStart="true" 
     android:layout_alignRight="@+id/lblName" 
     android:layout_alignEnd="@+id/lblName" 
     android:layout_below="@+id/lblName" /> 
</RelativeLayout>

Вы можете создать свой собственный список объектов:

Contact.java:

public class Contact { 
    private String name; 
    private String number; 

    public Contact(String name, String number) { 
     this.name = name; 
     this.number = number; 
    } 

    public String getName() { 
     return name; 
    } 

    public void setName(String name) { 
     this.name = name; 
    } 

    public String getNumber() { 
     return number; 
    } 

    public void setNumber(String number) { 
     this.number = number; 
    } 
} 

row_layout.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" android:layout_width="match_parent" 
    android:layout_height="match_parent"> 


    <TextView 
     android:id="@+id/name" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content"/> 


    <TextView 
     android:id="@+id/number" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" /> 

</LinearLayout> 

ContactListAdapter.java:

public class ContactListAdapter extends BaseAdapter { 
    private LayoutInflater mInflater; 
    private List<Contact> mContactList; 

    public ContactListAdapter(Activity activity, List<Contact> mContactList) { 
     mInflater = (LayoutInflater) activity.getSystemService(
       Context.LAYOUT_INFLATER_SERVICE); 
     this.mContactList = mContactList; 
    } 

    @Override 
    public int getCount() { 
     return mContactList.size(); 
    } 

    @Override 
    public Object getItem(int position) { 
     return mContactList.get(position); 
    } 

    @Override 
    public long getItemId(int position) { 
     return position; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     View rowView; 

     // Get item_layout: 
     rowView = mInflater.inflate(R.layout.row_layout, null); 

     // Get TextView from row_layout: 
     TextView textName = 
       (TextView) rowView.findViewById(R.id.name); 
     TextView textNumber = 
       (TextView) rowView.findViewById(R.id.number); 

     // Get name and number from current position: 
     Contact myContact = mContactList.get(position); 
     textName.setText(myContact.getName()); 
     textNumber.setText(myContact.getNumber()); 

     return rowView; 
    } 
} 

И наконец MainActivity.java:

public class MainActivity extends AppCompatActivity { 

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

      List<Contact> contactList = new ArrayList<>(); 

      StringBuffer sb = new StringBuffer(); 
      String strOrder = android.provider.CallLog.Calls.DATE + " DESC"; 
    /* Query the CallLog Content Provider */ 
      Cursor managedCursor = managedQuery(CallLog.Calls.CONTENT_URI, null, 
       null, null, strOrder); 
      int name = managedCursor.getColumnIndex(CallLog.Calls.CACHED_NAME); 
      int number = managedCursor.getColumnIndex(CallLog.Calls.NUMBER); 
      int type = managedCursor.getColumnIndex(CallLog.Calls.TYPE); 
      int date = managedCursor.getColumnIndex(CallLog.Calls.DATE); 
      int duration = managedCursor.getColumnIndex(CallLog.Calls.DURATION); 
     //sb.append("Call Log :"); 
      while (managedCursor.moveToNext()) { 
      String namee = managedCursor.getString(name); 
      String phNum = managedCursor.getString(number); 
      String callTypeCode = managedCursor.getString(type); 
      String strcallDate = managedCursor.getString(date); 
      Date callDate = new Date(Long.valueOf(strcallDate)); 
      String callDuration = managedCursor.getString(duration); 
      String callType = null; 
      int callcode = Integer.parseInt(callTypeCode); 

      switch (callcode) { 
       case CallLog.Calls.OUTGOING_TYPE: 
        callType = "Outgoing"; 
        break; 
       case CallLog.Calls.INCOMING_TYPE: 
        callType = "Incoming"; 
        break; 
       case CallLog.Calls.MISSED_TYPE: 
        callType = "Missed"; 
        break; 
      } 
      contactList.add(new Contact(namee, phNum)); 
     } 

      // Add list to your custom adapter 
      ListView myListView = (ListView) findViewById(R.id.liste); 
      ContactListAdapter mAdapter = new ContactListAdapter(this, contactList); 

      // Set Adapter 
      myListView.setAdapter(mAdapter); 

     } 
    } 

activity_main.xml:

<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

    <ListView 
     android:id="@+id/liste" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_gravity="center" /> 

</RelativeLayout>
