Question

有谁能告诉我如何在自定义列表视图中显示电话号码和联系人姓名？代码粘贴在

下面

import android.app.Activity;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.SimpleCursorAdapter;

public class AddContacts extends Activity implements OnClickListener {

    ListView list;
    Cursor cursor;
    SimpleCursorAdapter adapter;
    String phoneNumber;
    Button AddNumber;
    EditText number1;
    EditText number2;
    EditText number3;
    String contact1;
    String contact2;
    CheckBox checkBox;
    String contact_name;

    static final String TAG = "In AddContacts";

    @SuppressWarnings("deprecation")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.listview);
        AddNumber = (Button) findViewById(R.id.AddNumbers);
        number1 = (EditText) findViewById(R.id.NumberField1);
        number2 = (EditText) findViewById(R.id.NumberField2);
        number3 = (EditText) findViewById(R.id.NumberField3);
        AddNumber.setOnClickListener(this);
        list = (ListView) findViewById(R.id.lists);


        Log.d(TAG, "onCreate");



        Cursor cursor = getContentResolver().query(
                ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null,
                null, null);

        String[] nameNumberArray = new String[cursor.getCount()];
        Log.d("rows", Integer.toString(cursor.getCount()));

        Log.d("phone", "here");
        while (cursor.moveToNext()) {
            String phoneNumber =

            cursor.getString(cursor
                    .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
            String name = cursor.getString(cursor
                    .getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
            Log.i("Number + Name", phoneNumber + name);
        }
        if (cursor.getCount() > 0) {

            int i = 0;
            if (cursor.moveToFirst()) {
                do {
                    phoneNumber = cursor
                            .getString(cursor
                                    .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

                    contact_name = cursor
                            .getString(cursor
                                    .getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                    nameNumberArray[i] = contact_name + "  , " + phoneNumber;
                    i++;
                } while (cursor.moveToNext());
            }

        }

        final String[] FROM = { nameNumberArray[0], nameNumberArray[1] };
        final int[] TO = { R.id.contact_name, R.id.phone_number, };
        adapter = new SimpleCursorAdapter(this, R.layout.row, cursor, FROM, TO);
        list.setAdapter(adapter);
        cursor.close();
    }

    @Override
    public void onClick(View v) {


        Log.d(TAG, "onClicked method");


    }
}

ROW.xml文件是一个自定义listView，带有一个复选框和两个textView。代码从联系人中提取数据并将其显示在LogCat中。我无法弄清楚如何使用simpleCursorAdapter在我的自定义视图中显示名称和数字。

row.xml文件

    <?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/contact_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:text="John Doe"
        android:textAppearance="?android:attr/textAppearanceLarge" />

    <TextView
        android:id="@+id/phone_number"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/contact_name"
        android:text="(999)999-9999"
        android:textAppearance="?android:attr/textAppearanceMedium" />

    <CheckBox
        android:id="@+id/checkBox_id"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true" />

</RelativeLayout>

任何人都可以指导我吗？感谢。

由于op要求使用自定义适配器的解决方案，我已经发布了以下内容。（来自评论）

Display.java

public class Display extends Activity implements OnItemClickListener{

    List<String> name1 = new ArrayList<String>();
    List<String> phno1 = new ArrayList<String>();
    MyAdapter ma ;
    Button select;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.display);

        getAllContacts(this.getContentResolver());
        ListView lv= (ListView) findViewById(R.id.lv);
            ma = new MyAdapter();
            lv.setAdapter(ma);
            lv.setOnItemClickListener(this); 
            lv.setItemsCanFocus(false);
            lv.setTextFilterEnabled(true);
            // adding
           select = (Button) findViewById(R.id.button1);
        select.setOnClickListener(new OnClickListener()
        {

            @Override
            public void onClick(View v) {
                  StringBuilder checkedcontacts= new StringBuilder();
                System.out.println(".............."+ma.mCheckStates.size());
                for(int i = 0; i < name1.size(); i++)

                    {
                    if(ma.mCheckStates.get(i)==true)
                    {
                         checkedcontacts.append(name1.get(i).toString());
                         checkedcontacts.append("\n");

                    }
                    else
                    {
                        System.out.println("Not Checked......"+name1.get(i).toString());
                    }


                }

                Toast.makeText(Display.this, checkedcontacts,1000).show();
            }       
        });


    }
    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
        // TODO Auto-generated method stub
         ma.toggle(arg2);
    }

    public  void getAllContacts(ContentResolver cr) {

        Cursor phones = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null);
        while (phones.moveToNext())
        {
          String name=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
          String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
          System.out.println(".................."+phoneNumber); 
          name1.add(name);
          phno1.add(phoneNumber);
        }

        phones.close();
     }
    class MyAdapter extends BaseAdapter implements CompoundButton.OnCheckedChangeListener
    {  private SparseBooleanArray mCheckStates;
       LayoutInflater mInflater;
        TextView tv1,tv;
        CheckBox cb;
        MyAdapter()
        {
            mCheckStates = new SparseBooleanArray(name1.size());
            mInflater = (LayoutInflater)Display.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        }
        @Override
        public int getCount() {
            // TODO Auto-generated method stub
            return name1.size();
        }

        @Override
        public Object getItem(int position) {
            // TODO Auto-generated method stub
            return position;
        }

        @Override
        public long getItemId(int position) {
            // TODO Auto-generated method stub

            return 0;
        }

        @Override
        public View getView(final int position, View convertView, ViewGroup parent) {
            // TODO Auto-generated method stub
            View vi=convertView;
            if(convertView==null)
             vi = mInflater.inflate(R.layout.row, null); 
             TextView tv= (TextView) vi.findViewById(R.id.textView1);
             tv1= (TextView) vi.findViewById(R.id.textView2);
             cb = (CheckBox) vi.findViewById(R.id.checkBox1);
             tv.setText("Name :"+ name1.get(position));
             tv1.setText("Phone No :"+ phno1.get(position));
             cb.setTag(position);
             cb.setChecked(mCheckStates.get(position, false));
             cb.setOnCheckedChangeListener(this);

            return vi;
        }
         public boolean isChecked(int position) {
                return mCheckStates.get(position, false);
            }

            public void setChecked(int position, boolean isChecked) {
                mCheckStates.put(position, isChecked);
                System.out.println("hello...........");
                notifyDataSetChanged();
            }

            public void toggle(int position) {
                setChecked(position, !isChecked(position));
            }
        @Override
        public void onCheckedChanged(CompoundButton buttonView,
                boolean isChecked) {
            // TODO Auto-generated method stub

             mCheckStates.put((Integer) buttonView.getTag(), isChecked);         
        }   
    }   
}

display.xml

<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" >

   <ListView
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:layout_above="@+id/button1"

       android:id="@+id/lv"/>

     <Button
         android:id="@+id/button1"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:layout_alignParentBottom="true"
         android:layout_centerHorizontal="true"
         android:text="Select" />

</RelativeLayout>

说明：

以上使用自定义适配器。自定义布局row.xml包含2个textviews和一个复选框，每行都会显示一个。 getAllContacts()将从联系人列表中获取所有联系人，并将其存储在列表中。

自定义适配器显示为每行充气的自定义布局中的项目。

勾选复选框并单击显示屏会显示带有所选联系人姓名的祝酒词。

我认为您应该再次调用cursor.moveToFirst()，然后再将其传递给SimpleCursorAdapter，因为现在您正在发送“已完成”的游标。

除此之外，你的代码似乎很好。您可以将它与代码here进行比较，代码执行类似的操作（但使用用户定义的数据库）。
