Question

所以我的SMS短信课程正常工作。但是，我希望当用户点击edittext输入电话号码时...手机的电话簿加载，用户可以从那里选择一个或多个联系人，短信将转到所有选定的联系人。如何使用电话簿为我的短信加载和选择联系人？

我有点陷入困境我可以得到解释：）

类别：

    Button btnSendSMS;
    EditText txtPhoneNo;
    EditText txtMessage;

  private static final int ACTION_PICK_CONTACT=1;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_send_sms);
        btnSendSMS = (Button) findViewById(R.id.btnSendSMS);
        txtPhoneNo = (EditText) findViewById(R.id.txtPhoneNo);
        txtMessage = (EditText) findViewById(R.id.txtMessage);

        txtPhoneNo.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

像这样使用：

int ACTION_PICK_CONTACT=1;

//Call this in your onclick event
Intent i = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(i, ACTION_PICK_CONTACT);

//This is called when user has selected a contact
public void onActivityResult(int reqCode, int resCode, Intent data) {
   super.onActivityResult(reqCode, resultCode, data);

   switch (reqCode) {
     case (ACTION_PICK_CONTACT) :
        if (resCode == Activity.RESULT_OK) {

          Uri contact = data.getData();
          Cursor cursor =  managedQuery(contact, null, null, null, null);
          if (cursor.moveToFirst()) {
            String contact_id =cursor.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts._ID));

            Cursor phoneCursor = getContentResolver().query( 
                   ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null, 
                   ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contact_id, 
                   null, null);
            phoneCursor.moveToFirst();
            String phoneNumber = phoneCursor.getString(phoneCursor.getColumnIndex("data1")); //THE NUMBER TO SEND YOUR SMS
            txtPhoneNo.setText(phoneNumber);
          }
        }
        break;
    }
}

访问电话簿中的联系人以获取SMS消息？
