初学android之发短信

一、AndroidManifest.xml

---

获取发短信权限

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="xidian.dy.com.chujia">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
    <uses-permission android:name="android.permission.SEND_SMS"/>
</manifest>

二、编写界面

---

<?xml version="1.0" encoding="utf-8"?>
<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"
    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="xidian.dy.com.chujia.MainActivity">


    <EditText
        android:id="@+id/phone"
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:hint="请输入手机号"/>
    <EditText
        android:id="@+id/content"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:lines="5"
        android:gravity="top"
        android:hint="请输入短信内容"/>
    <Button
        android:id="@+id/call"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/input"
        android:text="拨打"
        android:onClick="showView"/>
</LinearLayout>

三、绑定事件

---

package xidian.dy.com.chujia;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

import java.util.List;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button bt = (Button) findViewById(R.id.call);
        bt.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                EditText etPhone = (EditText) findViewById(R.id.phone);
                String phone = etPhone.getText().toString();
                EditText etMsg = (EditText) findViewById(R.id.content);
                String msg = etMsg.getText().toString();
                //获取信息管理器
                SmsManager smg = SmsManager.getDefault();
                //切割短息
                List<String> list = smg.divideMessage(msg);
                //发送消息
                for (String str : list) {
                    smg.sendTextMessage(phone, null, str, null, null);
                }
            }
        });
    }
    public void showView(View v){
        Log.i("this", "HHH");
    }
}
