Android 手机发送短信

参照网上的例子，做了一个手机发送短信的app。

有两种发送方法：第一种方法测试没有信息的发送记录，第二种调用的sms的Activity还要自行操作。

首先是xml布局文件代码：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/main_title" />

    <EditText
        android:id="@+id/phone"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:hint="@string/main_phone"
        android:inputType="phone" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/main_text" />

    <EditText
        android:id="@+id/text"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:inputType="textMultiLine" />

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:gravity="center_horizontal"
        android:orientation="vertical" >

        <Button
            android:id="@+id/send"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/main_send" />

        <Button
            android:id="@+id/send2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/main_send" />
    </LinearLayout>


</LinearLayout>

然后是strings.xml文件

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <string name="app_name">SendText</string>
    <string name="action_settings">Settings</string>
    <string name="hello_world">Hello world!</string>
    <string name="main_title">发送短信</string>
    <string name="main_phone">请输入电话号码</string>
    <string name="main_text">请输入内容</string>
    <string name="main_send">发送</string>
    <string name="main_send_finish">发送完成</string>

</resources>

MainActivity的代码

package cn.yzy.sendtext;

import java.util.List;

import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.telephony.gsm.SmsManager;
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 phone;
  private EditText text;
  private Button send;
  private Button send2;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    phone = (EditText) findViewById(R.id.phone);
    text = (EditText) findViewById(R.id.text);
    send = (Button) findViewById(R.id.send);
    send2 = (Button) findViewById(R.id.send2);

    send.setOnClickListener(new OnClickListener() {

      @Override
      public void onClick(View arg0) {
        // TODO Auto-generated method stub
        String phone_number = phone.getText().toString().trim();
        String sms_content = text.getText().toString().trim();
        if (phone_number.equals("")) {
          Toast.makeText(MainActivity.this, R.string.main_phone,
              Toast.LENGTH_LONG).show();
        } else {
          SmsManager smsManager = SmsManager.getDefault();
          if (sms_content.length() > 70) {
            List<String> contents = smsManager
                .divideMessage(sms_content);
            for (String sms : contents) {
              smsManager.sendTextMessage(phone_number, null,
                  sms_content, null, null);

            }
          } else {
            smsManager.sendTextMessage(phone_number, null,
                sms_content, null, null);

          }
          Toast.makeText(MainActivity.this,
              R.string.main_send_finish, Toast.LENGTH_LONG)
              .show();
        }

      }
    });

    send2.setOnClickListener(new OnClickListener() {

      @Override
      public void onClick(View arg0) {
        // TODO Auto-generated method stub
        String phone_number = phone.getText().toString().trim();
        String sms_content = text.getText().toString().trim();

        Uri uri = Uri.parse("smsto://" + phone_number);
        Intent intent = new Intent(Intent.ACTION_SENDTO, uri);
        intent.putExtra("sms_body", "send detail");
        startActivity(intent);
      }
    });
  }

  @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;
  }

}

记得加发送短信的权限

<uses-permission android:name="android.permission.SEND_SMS" />
