我正在制作一个Android应用程序,需要打电话给手机的联系人列表。我需要调用“联系人列表”功能,选择一个联系人,然后返回到我的应用程序,并显示联系人的姓名。这是我在互联网上得到的代码,但它不起作用。

import android.app.ListActivity;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.Contacts.People;
import android.view.View;
import android.widget.ListAdapter;
import android.widget.ListView;
import android.widget.SimpleCursorAdapter;
import android.widget.TextView;

public class Contacts extends ListActivity {

    private ListAdapter mAdapter;
    public TextView pbContact;
    public static String PBCONTACT;
    public static final int ACTIVITY_EDIT=1;
    private static final int ACTIVITY_CREATE=0;

    // Called when the activity is first created. 
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        Cursor C = getContentResolver().query(People.CONTENT_URI, null, null, null, null);
        startManagingCursor(C);

        String[] columns = new String[] {People.NAME};
        int[] names = new int[] {R.id.row_entry};

        mAdapter = new SimpleCursorAdapter(this, R.layout.mycontacts, C, columns, names);
        setListAdapter(mAdapter);
    } // end onCreate()
    // Called when contact is pressed
    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);

        Cursor C = (Cursor) mAdapter.getItem(position);
        PBCONTACT = C.getString(C.getColumnIndex(People.NAME));

        // RHS 05/06
        //pbContact = (TextView) findViewById(R.id.myContact);
        //pbContact.setText(new StringBuilder().append("b"));

        Intent i = new Intent(this, NoteEdit.class);
        startActivityForResult(i, ACTIVITY_CREATE);
    }
}

我不完全确定您的示例代码应该做什么,但是下面的代码片段应该可以帮助您“调用联系人列表函数,选择一个联系人,然后使用联系人的姓名返回到[您的]应用程序”。

这个过程有三个步骤。

1。权限

添加将联系人数据读取到应用程序清单的权限。

<uses-permission android:name="android.permission.READ_CONTACTS"/>

2。调用联系人选取器

在您的活动中,创建一个意图,要求系统查找一个可以从联系人URI中的项目执行选择操作的活动。

Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);

呼叫 startActivityForResult ,传递此意图(和请求代码整数, PICK_CONTACT 在本例中)。这将导致Android启动一个注册为支持的活动 ACTION_PICK 上 People.CONTENT_URI ,然后在进行选择(或取消选择)时返回到此活动。

startActivityForResult(intent, PICK_CONTACT);

三。倾听结果

在您的活动中,重写 onActivityResult 方法来监听在步骤2中启动的“选择联系人”活动的返回。您应该检查返回的请求代码是否与您期望的值匹配,结果代码是否为 RESULT_OK .

您可以通过调用 getData() 上数据意向参数。要获取所选联系人的名称,需要使用该URI创建新查询并从返回的光标中提取名称。

@Override
public void onActivityResult(int reqCode, int resultCode, Intent data) {
  super.onActivityResult(reqCode, resultCode, data);

  switch (reqCode) {
    case (PICK_CONTACT) :
      if (resultCode == Activity.RESULT_OK) {
        Uri contactData = data.getData();
        Cursor c =  getContentResolver().query(contactData, null, null, null, null);
        if (c.moveToFirst()) {
          String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
          // TODO Whatever you want to do with the selected contact name.
        }
      }
      break;
  }
}

我这样做是为了Android 2.2 Froyo版本: 基本上使用Eclipse创建一个类,比如: 公共类SomePickContactName扩展活动

然后插入此代码。请记住添加我的代码版本中引用的私有类变量和常量:

protected void onCreate(Bundle savedInstanceState) 
{
  super.onCreate(savedInstanceState);       
  Intent intentContact = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); 
  startActivityForResult(intentContact, PICK_CONTACT);
}//onCreate

public void onActivityResult(int requestCode, int resultCode, Intent intent) 
{

  if (requestCode == PICK_CONTACT)
  {         
    getContactInfo(intent);         
    // Your class variables now have the data, so do something with it. 
  }
}//onActivityResult

protected void getContactInfo(Intent intent)
{

   Cursor cursor =  managedQuery(intent.getData(), null, null, null, null);      
   while (cursor.moveToNext()) 
   {           
       String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
       name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME)); 

       String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));

       if ( hasPhone.equalsIgnoreCase("1"))
           hasPhone = "true";
       else
           hasPhone = "false" ;

       if (Boolean.parseBoolean(hasPhone)) 
       {
        Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,null, null);
        while (phones.moveToNext()) 
        {
          phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
        }
        phones.close();
       }

       // Find Email Addresses
       Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,null,ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId,null, null);
       while (emails.moveToNext()) 
       {
        emailAddress = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
       }
       emails.close();

    Cursor address = getContentResolver().query(
                ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_URI,
                null,
                ContactsContract.CommonDataKinds.StructuredPostal.CONTACT_ID + " = " + contactId,
                null, null);
    while (address.moveToNext()) 
    { 
      // These are all private class variables, don't forget to create them.
      poBox      = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POBOX));
      street     = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.STREET));
      city       = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.CITY));
      state      = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.REGION));
      postalCode = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POSTCODE));
      country    = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.COUNTRY));
      type       = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.TYPE));
    }  //address.moveToNext()   
  }  //while (cursor.moveToNext())        
   cursor.close();
}//getContactInfo

使用contactsControlAPI四处寻找API级别5的解决方案,您可以使用以下方法稍微修改上面的代码:

  Intent intent = new Intent(Intent.ACTION_PICK);
  intent.setType(ContactsContract.Contacts.CONTENT_TYPE);
  startActivityForResult(intent, PICK_CONTACT);

然后在OnActivityResult中使用列名:

  ContactsContract.Contacts.DISPLAY_NAME

        Cursor phones = getContentResolver().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 Number=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

        }

takrl cck 14 年前

public void onActivityResult(int requestCode, int resultCode, Intent intent) 
{
  if (requestCode == PICK_CONTACT && intent != null) //here check whether intent is null R not
  {  
  }
}

因为如果不选择任何联系人,它将给出一个异常。所以最好检查一下这种情况。

令我惊讶的是,你不需要用户权限的联系人来读取姓名和一些基本信息(联系人是星标的,最后一次通话时间是什么)。但是,您需要权限才能阅读联系人的详细信息,如电话号码。

使用Android联系人列表时要小心。

除了HTC One和Sony Xperia外,阅读上述方法中的联系人列表对大多数Android设备都有效。 浪费了我六个星期的时间 想弄清楚是怎么回事!

大多数在线教程几乎是相似的-首先阅读“所有”联系人,然后显示在 Listview 具有 ArrayAdapter . 这不是内存高效的解决方案。与其先在其他网站上寻找解决方案,不如先看看developer.android.com。如果developer.android.com上没有可用的解决方案,您应该找别的地方。

解决方案是使用 CursorAdapter 而不是 定制 用于检索联系人列表。使用 定制 可以在大多数设备上工作,但效率不高。这个 游标适配器 在运行时仅检索联系人列表的一部分, ListView 正在滚动。

public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    ...
    // Gets the ListView from the View list of the parent activity
    mContactsList =
        (ListView) getActivity().findViewById(R.layout.contact_list_view);
    // Gets a CursorAdapter
    mCursorAdapter = new SimpleCursorAdapter(
            getActivity(),
            R.layout.contact_list_item,
            null,
            FROM_COLUMNS, TO_IDS,
            0);
    // Sets the adapter for the ListView
    mContactsList.setAdapter(mCursorAdapter);
}

我用这种方法来读取联系人

public static List<ContactItem> readPhoneContacts(Context context) {
        List<ContactItem> contactItems = new ArrayList<ContactItem>();
        try {
            Cursor cursor = context.getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null,
                    null, null, "upper("+ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + ") ASC");

            /*context.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,

                    new String[] { id },
                    ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME+" ASC");*/

            Integer contactsCount = cursor.getCount(); // get how many contacts you have in your contacts list
            if (contactsCount > 0) {
                while (cursor.moveToNext()) {

                    String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
                    String contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

嗨,我有一个代码可以按共享首选项将联系人保存到数据库中这是我的密码

public class Main22Activity extends AppCompatActivity {
    EditText nameInput,phoneInput;
    TextView LargeText;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main22);
        nameInput = (EditText) findViewById(R.id.nameInput);
        phoneInput = (EditText) findViewById(R.id.phoneInput);

        LargeText = (TextView) findViewById(R.id.textView2);
    }

    public void saveInfo (View view){
        SharedPreferences sharedPref = getSharedPreferences("nameInfo" , Context.MODE_PRIVATE);
        SharedPreferences.Editor editor= sharedPref.edit();
        editor.putString("name", nameInput.getText().toString());
        editor.putString("phone", phoneInput.getText().toString());
        editor.apply();

-> Add a permission to read contacts data to your application manifest.

<uses-permission android:name="android.permission.READ_CONTACTS"/>

-> Use Intent.Action_Pick in your Activity like below

Intent contactPickerIntent = new Intent(Intent.ACTION_PICK,
                ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
        startActivityForResult(contactPickerIntent, RESULT_PICK_CONTACT);

-> Then Override the onActivityResult()

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // check whether the result is ok
        if (resultCode == RESULT_OK) {
            // Check for the request code, we might be usign multiple startActivityForReslut
            switch (requestCode) {
            case RESULT_PICK_CONTACT:
               Cursor cursor = null;
        try {
            String phoneNo = null ;
            String name = null;           
            Uri uri = data.getData();            
            cursor = getContentResolver().query(uri, null, null, null, null);
            cursor.moveToFirst();           
            int  phoneIndex =cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
            phoneNo = cursor.getString(phoneIndex); 

            textView2.setText(phoneNo);
        } catch (Exception e) {
            e.printStackTrace();
        }
                break;
            }
        } else {
            Log.e("MainActivity", "Failed to pick contact");
        }
    }

This will work check it out

我用 code 由@colin mackenzie-iii提供。非常感谢!

对于正在寻找“deprecated”managedquery替换项的用户:

第一,假设使用v4支持库:

import android.support.v4.app.LoaderManager;
import android.support.v4.content.CursorLoader;
import android.support.v4.content.Loader;

第二:

your_(activity)_class implements LoaderManager.LoaderCallbacks<Cursor>

第三,

// temporarily store the 'data.getData()' from onActivityResult
private Uri tmp_url;

第4,覆盖回调:

@Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
    // create the loader here!
    CursorLoader cursorLoader = new CursorLoader(this, tmp_url, null, null, null, null);
    return cursorLoader;
}

@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
    getContactInfo(cursor); // here it is!
}

@Override
public void onLoaderReset(Loader<Cursor> loader) {
}

第五:

public void initLoader(Uri data){
    // will be used in onCreateLoader callback
    this.tmp_url = data;
    // 'this' is an Activity instance, implementing those callbacks
    this.getSupportLoaderManager().initLoader(0, null, this);
}

第六, code above ,但我将签名参数从意向更改为光标:

protected void getContactInfo(Cursor cursor)
{

   // Cursor cursor =  managedQuery(intent.getData(), null, null, null, null);      
   while (cursor.moveToNext()) 
   {
        // same above ...
   }

第7,调用initloader:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (PICK_CONTACT == requestCode) {
        this.initLoader(data.getData(), this);
    }
}

第八,别忘了这段代码

    Intent intentContact = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
    this.act.startActivityForResult(intentContact, PICK_CONTACT);
