Question

我想选择构建一个应用程序，其中包括从本机联系人中选择电子邮件ID。如何在应用程序内获取所选的电子邮件值。如何实现这一点任何独立的示例都将非常有用。谢谢。

实施联系人列表，如下所示：

   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);
}

 }

将活动的EditText框中的所选联系人复制如下：

      @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"));   
   }

如何从Android联系人获取所选的电子邮件到应用程序？
