<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.example.message"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk        android:minSdkVersion="10"        android:targetSdkVersion="12" />    <uses-permission android:name="android.permission.SEND_SMS"/>    //添加这一句    <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <activity            android:name="com.example.message.MainActivity"            android:label="@string/app_name" >            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>    </application></manifest>

MainActivity.java

package com.example.message;import android.os.Bundle;import android.app.Activity;import android.telephony.SmsManager;import android.text.TextUtils;import android.view.Menu;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 Activity {	private EditText et_number;	private EditText et_content;	private Button send;	@Override	protected void onCreate(Bundle savedInstanceState) {		super.onCreate(savedInstanceState);		setContentView(R.layout.activity_main);		et_content = (EditText) findViewById(R.id.et_content);		et_number = (EditText) findViewById(R.id.et_number);		send = (Button) findViewById(R.id.button1);		send.setOnClickListener(new OnClickListener() {			@Override			public void onClick(View arg0) {				// TODO Auto-generated method stub				sendmessage();			}		});	}	public void sendmessage() {		String content = et_content.getText().toString();		String number = et_number.getText().toString();		if (TextUtils.isEmpty(number)) {			Toast.makeText(MainActivity.this, "号码不能为空", 4).show();			return;		} else {			SmsManager manager = SmsManager.getDefault();			manager.sendTextMessage(number, null, content, null, null);		}	}	@Override	public boolean onCreateOptionsMenu(Menu menu) {		// Inflate the menu; this adds items to the action bar if it is present.		getMenuInflater().inflate(R.menu.main, menu);		return true;	}}

需要注意的是

添加

sendTextMessage 添加包的时候，要添加

import android.telephony.SmsManager;

而不是这个包；

import android.telephony.gsm.SmsManager;
