Android学习笔记_2_发送短信

1、首先需要在AndroidManifest.xml文件中加入发送短信的权限

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

2、使用相对布局方式进行布局

　　hint：表示编辑框的提示信息

　　layout_below:在那个视图的下方

<RelativeLayout 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:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/tvPhone"
        android:id="@+id/tv1" />

    <EditText
        android:id="@+id/editPh"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/tv1"
        android:layout_below="@+id/tv1"
        android:hint="@string/phoneMsg"
        android:ems="10" />
    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/editPh"
        android:layout_below="@+id/editPh"
        android:text="@string/tvSMS" />
    <EditText
        android:id="@+id/etSMS"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/textView1"
        android:layout_below="@+id/textView1"
        android:ems="10" />
    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/etSMS"
        android:layout_below="@+id/etSMS"
        android:text="@string/send" />
</RelativeLayout>

3、string的资源文件

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="app_name">SMS</string>
    <string name="action_settings">Settings</string>
    <string name="tvPhone">请输入手机号</string>
    <string name="tvSMS">请输入短信内容</string>
    <string name="success">发送成功</string>
    <string name="fail">发送失败</string>
    <string name="phoneMsg">Please a phone number</string>
    <string name="send">发送</string>
</resources>

4、activity类的实现

public class MainActivity extends Activity {
    private EditText etPhone;
    private EditText etSMS;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        etPhone = (EditText)this.findViewById(R.id.editPh);//号码
        etSMS = (EditText)this.findViewById(R.id.etSMS);//短信内容
        Button btnSend = (Button)this.findViewById(R.id.button1);
        //注册事件
        btnSend.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View view) {
                String phone = etPhone.getText().toString();
                String sms = etSMS.getText().toString();
                SmsManager manager = SmsManager.getDefault();
                //如果短信太长，就分割开来在进行发送
                ArrayList<String> msgs = manager.divideMessage(sms);
                for (String msg : msgs) {
                    manager.sendTextMessage(phone, null, msg, null, null);
                }
                //参数分别表示上下文对象，显示消息，停留时间长短
                Toast.makeText(MainActivity.this, R.string.success, Toast.LENGTH_LONG).show();
            }
        });

    }

    @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;
    }

}
