android 入门学习笔记 电话簿查询

/*必须引用database.Cursor,Contacts.People
与 net.uri等类来使用联系人数据*/
import android.database.Cursor; 
import android.net.Uri; 
import android.provider.Contacts.People; 

 

/*建构Uri来取得联系人的资源位置*/
        Uri uri = Uri.parse("content://contacts/people"); 
        /*通过Intent来取得联系人数据并返回所选的值*/
        Intent intent = new Intent(Intent.ACTION_PICK, uri);
        /*打开新的Activity并期望该Activity返回值*/
        startActivityForResult(intent, PICK_CONTACT_SUBACTIVITY); 

@Override 
  protected void onActivityResult 
(int requestCode, int resultCode, Intent data) 
  { 
    // TODO Auto-generated method stub 
    switch (requestCode) 
    {  
      case PICK_CONTACT_SUBACTIVITY: 
        final Uri uriRet = data.getData(); 
        if(uriRet != null) 
        { 
          try 
          { 
            /* 必须要有android.permission.READ_CONTACTS权限 */ 
            Cursor c = managedQuery(uriRet, null, null, null, null); 
            /*将Cursor移到资料最前端*/
            c.moveToFirst(); 
            /*取得联系人的姓名*/
            String strName =  
            c.getString(c.getColumnIndexOrThrow(People.NAME)); 
            /*取得联系人的电话*/
            String strPhone =  
            c.getString(c.getColumnIndexOrThrow(People.NUMBER)); 
            /*将姓名与电话写入EditText01,EditText02中*/
            mEditText01.setText(strName); 
            mEditText02.setText(strPhone);
          } 
          catch(Exception e) 
          { 
            /*将错误信息在TextView中显示*/
            mTextView01.setText(e.toString()); 
            e.printStackTrace(); 
          } 
        } 
        break; 
    } 
    super.onActivityResult(requestCode, resultCode, data); 
  }

 

如果只是查询电话簿，需 <uses-permission android:name="android.permission.READ_CONTACTS"></uses-permission>

如果需要增加修改删除则需 <uses-permission android:name="android.permission.WRITE_CONTACTS"></uses-permission>
