activity代碼：

package com.example.msgSend;import java.util.List;import android.os.Bundle;import android.support.v7.app.ActionBarActivity;import android.telephony.SmsManager;import android.text.TextUtils;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.EditText;import android.widget.Toast;public class MainActivity extends ActionBarActivity implements OnClickListener{/** 電話號碼 */private EditText etPhoneNum;/** 簡訊內容 */private EditText etContent;/** 發送按鈕 */private Button btSend;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);//獲得組件etPhoneNum = (EditText)findViewById(R.id.et_phoneNum);etContent = (EditText)findViewById(R.id.et_content);btSend = (Button)findViewById(R.id.bt_send);System.out.println("擷取成功");//註冊點擊事件btSend.setOnClickListener(this);}@Overridepublic void onClick(View v) {switch (v.getId()) {case R.id.bt_send:sendMessage();break;default:break;}}//實現簡訊發送private void sendMessage() {String phoneNum = etPhoneNum.getText().toString();String content = etContent.getText().toString();//多士提示if (TextUtils.isEmpty(phoneNum) || TextUtils.isEmpty(content)) {Toast.makeText(this, "手機號碼和簡訊都不可為空", Toast.LENGTH_LONG).show();return ;}SmsManager smsManager = SmsManager.getDefault();//簡訊是有長度限制的， 直接對內容進行分割List<String> contents = smsManager.divideMessage(content);//發送for (String content1 : contents) {smsManager.sendTextMessage(phoneNum, null, content1, null, null);}}}
