我们可以通过意图在android中发送短信。你只需要编写4行代码即可在android中发送短信。

//Getting intent and PendingIntent instance

Intent intent=new Intent(getApplicationContext(), MainActivity.class);

PendingIntent pi=PendingIntent.getActivity(getApplicationContext(), 0, intent, 0);

//Get the SmsManager instance and call the sendTextMessage method to send message

SmsManager sms=SmsManager.getDefault();

sms.sendTextMessage("8802177690", null, "hello srcmini", pi, null);

在Android中发送短信的示例

activity_main.xml

从面板上拖动2个edittexts，2个textviews和1个按钮，现在activity_main.xml文件将如下所示：

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

tools:context=".MainActivity" >

android:id="@+id/editText1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignParentRight="true"

android:layout_alignParentTop="true"

android:layout_marginRight="20dp"

android:ems="10" />

android:id="@+id/editText2"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignLeft="@+id/editText1"

android:layout_below="@+id/editText1"

android:layout_marginTop="26dp"

android:ems="10"

android:inputType="textMultiLine" />

android:id="@+id/textView1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignBaseline="@+id/editText1"

android:layout_alignBottom="@+id/editText1"

android:layout_toLeftOf="@+id/editText1"

android:text="Mobile No:" />

android:id="@+id/textView2"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignBaseline="@+id/editText2"

android:layout_alignBottom="@+id/editText2"

android:layout_alignLeft="@+id/textView1"

android:text="Message:" />

android:id="@+id/button1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignLeft="@+id/editText2"

android:layout_below="@+id/editText2"

android:layout_marginLeft="34dp"

android:layout_marginTop="48dp"

android:text="Send SMS" />

在Android-Manifest.xml文件中写入权限代码

你需要编写SEND_SMS权限，如下所示：

xmlns:androclass="http://schemas.android.com/apk/res/android"

package="com.example.sendsms"

android:versionCode="1"

android:versionName="1.0" >

android:minSdkVersion="8"

android:targetSdkVersion="16" />

android:allowBackup="true"

android:icon="@drawable/ic_launcher"

android:label="@string/app_name"

android:theme="@style/AppTheme" >

android:name="com.example.sendsms.MainActivity"

android:label="@string/app_name" >

活动类

让我们编写代码以通过意图拨打电话。

package com.example.sendsms;

import android.os.Bundle;

import android.app.Activity;

import android.app.PendingIntent;

import android.content.Intent;

import android.telephony.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 {

EditText mobileno, message;

Button sendsms;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

mobileno=(EditText)findViewById(R.id.editText1);

message=(EditText)findViewById(R.id.editText2);

sendsms=(Button)findViewById(R.id.button1);

//Performing action on button click

sendsms.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View arg0) {

String no=mobileno.getText().toString();

String msg=message.getText().toString();

//Getting intent and PendingIntent instance

Intent intent=new Intent(getApplicationContext(), MainActivity.class);

PendingIntent pi=PendingIntent.getActivity(getApplicationContext(), 0, intent, 0);

//Get the SmsManager instance and call the sendTextMessage method to send message

SmsManager sms=SmsManager.getDefault();

sms.sendTextMessage(no, null, msg, pi, null);

Toast.makeText(getApplicationContext(), "Message Sent successfully!", 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.activity_main, menu);

return true;

}

}

在Real Device(例如移动设备)上安装并运行apk文件以发送短信。

输出：
