如何從android聯繫人中選擇電子郵件到應用程序？

Question

我想選擇構建一個應用程序，其中包括從本地contacts.Aow選擇電子郵件ID如何可以在應用程序中獲得選定的電子郵件值。我可以如何實現這個任何獨立的例子將是有益的。謝謝。

1. 實現如下的聯繫人列表：

   public class contDetail extends Activity implements OnItemClickListener {  
   private static final String[] PROJECTION = new String[] {    
   ContactsContract.Contacts._ID,    
   ContactsContract.Contacts.DISPLAY_NAME,    
   ContactsContract.Contacts.HAS_PHONE_NUMBER,    
   ContactsContract.Contacts.LOOKUP_KEY 
   }; 
   private int mIdColumnIndex; 
   private int mHasPhoneColumnIndex; 
   private TextView mPhone; 
   @Override  
   public void onCreate(Bundle savedInstanceState) { 
       super.onCreate(savedInstanceState); 
        setContentView(R.layout.pickcontact); 
       mPhone = (TextView) findViewById(R.id.test); 
   ListView myList=(ListView)findViewById(R.id.list1); 
   Cursor c = managedQuery(ContactsContract.Contacts.CONTENT_URI, 
        PROJECTION, null, null, null);  
        mIdColumnIndex = c.getColumnIndex(ContactsContract.Contacts._ID);  
        mHasPhoneColumnIndex = c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER); 
        ListAdapter adapter = new SimpleCursorAdapter(this, 
          android.R.layout.simple_list_item_1,c, 
          new String[] { ContactsContract.Contacts.HAS_PHONE_NUMBER }, 
          new int[] { android.R.id.text1 }); 
        myList.setAdapter(adapter); 
        myList.setOnItemClickListener(this); 
        //setOnItemSelectedListener(this);  
   
       } 
   
       public void onItemClick(AdapterView<?>parent, View v, int position, long id) { 
   if (position >= 0) { 
   final Cursor c = (Cursor) parent.getItemAtPosition(position); 
   if (c.getInt(mHasPhoneColumnIndex) > 0) { 
   final long contactId = c.getLong(mIdColumnIndex); 
   final Cursor phones = getContentResolver().query( 
   ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
   new String[] { ContactsContract.CommonDataKinds.Phone.NUMBER }, 
   ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + contactId, null, 
   ContactsContract.CommonDataKinds.Phone.IS_SUPER_PRIMARY + " DESC"); 
   try {    
   phones.moveToFirst(); 
       mPhone.setText(phones.getString(0)); 
       String ph = phones.getString(0); 
       Intent intent = this.getIntent(); 
       intent.putExtra("SOMETHING",ph); 
       this.setResult(RESULT_OK, intent); 
       finish(); 
   
   } finally {     
   phones.close();  
   }   
   } else { 
   mPhone.setText(R.string.button_info_text); 
   }} 
       } 
   
       public void onNothingSelected(AdapterView parent) { 
   mPhone.setText(R.string.button_info_text); 
   } 
   
   } 
   

2. 拷貝到您的活動的EditText上框選定的聯繫人如下：

    @Override 
   protected void onActivityResult(int requestCode, int resultCode, Intent data)     { 
       super.onActivityResult(requestCode, resultCode, data); 
       if(resultCode==RESULT_OK && requestCode==1)  
       ed1.setText(data.getStringExtra("SOMETHING")); 
       if(resultCode==RESULT_OK && requestCode==2)  
       ed2.setText(data.getStringExtra("SOMETHING")); 
       }
