爲什麼選定的聯繫人不會出現在文本視圖中？

我正在爲聯繫人列表創建多選佈局。我成功地選擇了聯繫人。但是，不是在文本視圖中顯示聯繫人姓名，而是顯示爲字符串值。我只想讓聯繫人名稱顯示在TextView中，而不是字符串值。爲什麼選定的聯繫人不會出現在文本視圖中？

我有2個班。一類是挑選聯繫人。而另一個班則用於瀏覽和選擇聯繫人。

選定聯繫人活動

package com.droidnova.android.samples; 

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


    public class SelectContact extends Activity { 
private static final int PICK_CONTACT = 0; 
private Button btnPick; 

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

     btnPick = (Button)findViewById(R.id.button); 
     btnPick.setOnClickListener(new MyOnClickListener()); 


    } 
    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     if (requestCode == PICK_CONTACT) { 
      if (resultCode == RESULT_OK) { 
       Cursor contact = getContentResolver().query(data.getData(), null, null, null, null); 
       contact.moveToFirst(); 
       String name = contact.getString(contact.getColumnIndexOrThrow(People.NAME)); 


     } 

    } 
     } 
    private class MyOnClickListener implements View.OnClickListener { 
    @Override 
    public void onClick(View v) { 
     startActivityForResult(new Intent(Intent.ACTION_PICK),PICK_CONTACT); 
    } 
    } 
}

        +";"+PROJECTION[chosen.keyAt(i)]); 

      if(chosen.valueAt(i)){ 
       Selection.append(PROJECTION[chosen.keyAt(i)]+""); 
      } 

     } 
    }

}

這是我的logcat：

詳情什麼ü由「字符串值」在這裏..意思是如果你能證明logcat的O/P會有助於幫助你。 – 2010-12-02 04:56:50

試試這個..我使用此代碼獲取電子郵件和姓名從聯繫人。使用此代碼按您的要求

@Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) 
    {   


        if (resultCode == RESULT_OK) 
        { 
         if(requestCode==CONTACT_PICKER_EMAIL) 
         { 
          Cursor cursor = null; 
          String email = ""; 
          try 
          { 
           Uri result = data.getData(); 
           Log.v(DEBUG_TAG, "Got a contact result: " 
             + result.toString()); 

           // get the contact id from the Uri 
           String id = result.getLastPathSegment(); 

           // query for everything email 
           cursor = getContentResolver().query(Email.CONTENT_URI, 
             null, Email.CONTACT_ID + "=?", new String[] { id }, 
             null); 

           int emailIdx = cursor.getColumnIndex(Email.DATA); 

           // let's just get the first email 
           if (cursor.moveToFirst()) 
           { 
            email = cursor.getString(emailIdx);         
            txtconfirmBy.setText(email); 
           } 
           else 
           { 
            Log.w(DEBUG_TAG, "No results"); 
           } 
          } 
          catch (Exception e) 
          { 
           Log.e(DEBUG_TAG, "Failed to get email data", e); 
          } 
          finally 
          { 
           if (cursor != null) 
           { 
            cursor.close(); 
           }      

          }  

         } 
         else if (requestCode==CONTACT_PICKER_NAME) 
         { 
          Uri contactData = data.getData(); 
          Cursor c = managedQuery(contactData, null, null, null, null); 
          if (c.moveToFirst()) 
          {      
           String name = c.getString(c.getColumnIndexOrThrow(People.DISPLAY_NAME)); 
           txtparticipant.setText(name);   

          }  
        } 

        } 




    }

發送請求得到這樣

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

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