Question

我想要构建一个应用程序，在应用程序激活时通过帮助将消息发送给选定的联系人。我点击了激活切换时创建了一个选择联系人但无法添加消息功能的应用程序关键

textView1 = (TextView) findViewById(R.id.contact_number1); 
textView2 = (TextView) findViewById(R.id.contact_number2); 

public void pickAContactNumber(View view) 
{ 
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); 
startActivityForResult(intent, PICK_CONTACT1); 
} 

Answer 1

当你有得到接触呼叫活动，你会得到onActivityResult方法接触，并从那里你可以实现如下的逻辑，

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

    switch (reqCode) { 
     case (PICK_CONTACT1) : 
      if (resultCode == Activity.RESULT_OK) { 

       Uri contactData = data.getData(); 
       Cursor c = managedQuery(contactData, null, null, null, null); 
       if (c.moveToFirst()) { 

        String id =c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts._ID)); 
        String hasPhone =c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)); 

        if (hasPhone.equalsIgnoreCase("1")) { 
         Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ id, 
        null, null); 
          phones.moveToFirst(); 
          cNumber = phones.getString(phones.getColumnIndex("data1")); 
          System.out.println("number is:"+cNumber); 
        sendMessage(cNumber); 

        } 
        //String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 
       } 
      } 
      break; 
     } 
    } 

    public void sendMessage(String number) 
    { 
    }
