其实我的目标是获取联系人姓名和电话号码，但我的代码显示输出如此请填写电话号码这令我很烦，所以如果有人知道，请告诉我。提前致谢

在列表视图中显示名称和号码的活动...

public class FirstActivity extends Activity {

ListView list;
ArrayList<HashMap<String, String>> al = new ArrayList<HashMap<String,String>>();


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

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


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

    while(phones.moveToNext())
    {
        HashMap<String, String> nameNumberMap = new HashMap<String, String>();
        String contactName = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
        String contactNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
        nameNumberMap.put("Name",contactName);
        nameNumberMap.put("Number",contactNumber);
        al.add(nameNumberMap);

    }

    Log.e("check","as2");
    customAdapter adapter = new customAdapter(this, al);
    list.setAdapter(adapter);
    Log.e("check","as2"+al.size());



}
}

自定义适配器类

public class customAdapter extends BaseAdapter {

ArrayList<HashMap<String, String>> al = new ArrayList<HashMap<String,String>>();
Activity activity;
private static LayoutInflater inflater = null;

public customAdapter(Activity a, ArrayList<HashMap<String, String>> al) {
    Log.e("check", "");
    activity = a;
    this.al = al;
    inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

@Override
public int getCount() {
    // TODO Auto-generated method stub
     return al.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 position;
}

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

    View vi=convertView;
    if(convertView==null)
    {
    vi = inflater.inflate(R.layout.row_layout, null);
    }
    TextView name = (TextView) vi.findViewById(R.id.Name);
    TextView number = (TextView) vi.findViewById(R.id.Number);

    HashMap<String, String> contains = new HashMap<String, String>();
    contains = al.get(position);
    Log.e("value check:----", contains.get("Name"));
    name.setText(contains.get("Name"));
    number.setText(contains.get("Number"));
    return vi;
}

}

首次活动的XML

<LinearLayout 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"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".FirstActivity" 
android:orientation="vertical">

<ListView 
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content"></ListView>

</LinearLayout>

行布局的XML

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
 >


    <TextView 
    android:id="@+id/Name"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="30sp"
    />

    <TextView 
    android:id="@+id/Number"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="20sp"
    />

</LinearLayout>

修改

此代码用于联系人的搜索功能

我在这里做的是当用户继续输入编辑文本时，从联系人列表中搜索姓名联系人并显示在edittext下面的列表视图中......这类似于联系人列表中的默认联系人搜索功能或我们设备的电话簿

EditText edit_text=(EditText)findViewById(R.id.txtItem); edit_text.addTextChangedListener(new TextWatcher() { @Override public void afterTextChanged(Editable changed_text) { // TODO Auto-generated method stub //String search_value=getText(R.id.txtItem).toString(); //Toast.makeText(getApplicationContext(), changed_text,Toast.LENGTH_SHORT).show(); display_list(changed_text.toString(),changed_text.length(), NAME[0]); } }); } /** displaying the list of the best match contacts */ public void display_list(final String searchString,int searchStringLength, final String actionTOPerform) { listview =(ListView)findViewById(android.R.id.list); /** Defining the ArrayAdapter to set items to ListView */ adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, list); adapter.clear(); try { phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null); phones.moveToFirst(); while(phones.moveToNext()) { Name=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); if( (Name.toLowerCase()).contains(searchString.toLowerCase()) ) { adapter.notifyDataSetChanged(); } } } catch (StringIndexOutOfBoundsException e) { //Toast.makeText(getApplicationContext(), e.toString(),Toast.LENGTH_LONG).show(); // TODO: handle exception } /** Setting the adapter to the ListView */ setListAdapter(adapter); /** Setting up the call on item click from the list */ OnItemClickListener selectedItem = new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> arg0, View selectedContact, int arg2, long arg3) { String callcontact = ((TextView)selectedContact).getText().toString(); phones.moveToFirst(); while (phones.moveToNext()) { String Name=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); String Number=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); if(Name.compareToIgnoreCase(callcontact)== 0) { String url = "tel:"+Number; Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse(url)); startActivity(intent); } } } }; listview.setOnItemClickListener(selectedItem); }//end of display_list

我想显示联系人姓名和电话号码，但失败了
