如何调用Android联系人列表？

Question

我正在制作Android应用,需要拨打电话的联系人列表.我需要调用联系人列表功能,选择联系人,然后使用联系人姓名返回我的应用程序.这是我在互联网上获得的代码,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);
    }
}

Answer 1

我不是100%确定您的示例代码应该做什么,但以下代码段应该可以帮助您"调用联系人列表功能,选择联系人,然后返回[您的]应用程序的联系人姓名".

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.致电联系人选择器

在您的Activity中,创建一个Intent,要求系统查找可以从Contacts URI中的项目执行PICK操作的Activity.

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

调用startActivityForResult,传入此Intent(PICK_CONTACT在此示例中为请求代码整数).这将导致Android的推出其注册,以支持活动ACTION_PICK上People.CONTENT_URI,然后返回到时做出选择(或取消)这个活动.

startActivityForResult(intent, PICK_CONTACT);

3.听取结果

同样在您的Activity中,覆盖onActivityResult方法以侦听您在步骤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,结果代码是否正确RESULT_OK.

你可以通过调用获取选定联系人的URI getData()的数据意图参数.要获取所选联系人的名称,您需要使用该URI创建新查询并从返回的游标中提取名称.

@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发布:基本上使用eclipse来创建一个类:public class SomePickContactName extends Activity

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CONSTANTS:

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

Answer 3

使用ContactsContract API查看API Level 5解决方案,您可以使用以下内容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

以下是获取联系人的代码段:

package com.contact;

import android.app.Activity;
import android.content.ContentResolver;
import android.content.Intent;
import android.database.Cursor;

import android.provider.ContactsContract;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;

public class GetContactDemoActivity extends Activity implements OnClickListener {

private Button btn = null;
private TextView txt = null;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    btn = (Button) findViewById(R.id.button1);
    txt = (TextView) findViewById(R.id.textView1);

    btn.setOnClickListener(this);
}

@Override
public void onClick(View arg0) {
    if (arg0 == btn) {
        try {
            Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
            startActivityForResult(intent, 1);
        } catch (Exception e) {
            e.printStackTrace();
            Log.e("Error in intent : ", e.toString());
        }
    }
}

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

    try {
        if (resultCode == Activity.RESULT_OK) {
            Uri contactData = data.getData();
            Cursor cur = managedQuery(contactData, null, null, null, null);
            ContentResolver contect_resolver = getContentResolver();

            if (cur.moveToFirst()) {
                String id = cur.getString(cur.getColumnIndexOrThrow(ContactsContract.Contacts._ID));
                String name = "";
                String no = "";

                Cursor phoneCur = contect_resolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                        ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] { id }, null);

                if (phoneCur.moveToFirst()) {
                    name = phoneCur.getString(phoneCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
                    no = phoneCur.getString(phoneCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                }

                Log.e("Phone no & name :***: ", name + " : " + no);
                txt.append(name + " : " + no + "\n");

                id = null;
                name = null;
                no = null;
                phoneCur = null;
            }
            contect_resolver = null;
            cur = null;
            //                      populateContacts();
        }
    } catch (IllegalArgumentException e) {
        e.printStackTrace();
        Log.e("IllegalArgumentException :: ", e.toString());
    } catch (Exception e) {
        e.printStackTrace();
        Log.e("Error :: ", e.toString());
    }
}

}

Answer 6

完整的代码如下

    package com.testingContect;

    import android.app.Activity;
    import android.content.Intent;
    import android.database.Cursor;
    import android.net.Uri;
    import android.os.Bundle;
    import android.provider.ContactsContract;
    import android.provider.Contacts.People;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.widget.Button;
    import android.widget.EditText;
    import android.widget.Toast;

    public class testingContect extends Activity implements OnClickListener{
    /** Called when the activity is first created. */

    EditText ed;
    Button bt;
    int PICK_CONTACT;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        bt=(Button)findViewById(R.id.button1);
        ed =(EditText)findViewById(R.id.editText1);
        ed.setOnClickListener(this);
        bt.setOnClickListener(this);


    }

    @Override
    public void onClick(View v) {

        switch(v.getId())
        {
        case R.id.button1:

            break;
        case R.id.editText1:
             Intent intent = new Intent(Intent.ACTION_PICK);
              intent.setType(ContactsContract.Contacts.CONTENT_TYPE);
              startActivityForResult(intent, PICK_CONTACT);


            break;

        }

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

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

          Toast.makeText(this, "Contect LIST  =  "+name, Toast.LENGTH_LONG).show(); 
      }
    }//onActivityResult
}//class ends

Answer 7

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

因为没有选择任何联系,它将给出例外.所以最好检查这个条件.
