一、项目结构

二、activity_main.xml代码

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"      android:orientation="vertical"    >    <EditText        android:id="@+id/et_phone"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:hint="请输入号码"        android:inputType="phone"        />    <EditText         android:id="@+id/et_content"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:lines="5"        android:hint="请输入内容"        android:text="oohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohohooohhohohohohohohohohoho"        android:gravity="top"        />    <Button android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="发送"        android:onClick="send"        /></LinearLayout>

三、MainActivity.java代码

package com.example.sendnote;import java.util.ArrayList;import android.support.v7.app.ActionBarActivity;import android.telephony.SmsManager;import android.util.Log;import android.os.Bundle;import android.view.View;import android.widget.EditText;public class MainActivity extends ActionBarActivity {private static final String TAG="MainActivity";private EditText phone;private EditText content;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);phone=(EditText)findViewById(R.id.et_phone);content=(EditText)findViewById(R.id.et_content);}public void send(View v){String phoneText=phone.getText().toString();String contentText=content.getText().toString();Log.i(TAG, "发送号码:"+phoneText);Log.i(TAG, "发送内容:"+contentText);//直接使用短信api，进行发送SmsManager sm=SmsManager.getDefault();//如果短信过长，会导致短信不发送，在这先把短信内容处理为多个短信ArrayList<String> al=sm.divideMessage(contentText);for (String string : al) {sm.sendTextMessage(phoneText, null,string, null, null);}}}
