如何在android中发送短信 android发送短信|Android

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：

< RelativeLayout xmlns:androclass="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity" >< EditText 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" />< EditText 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" />< TextView 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:" />< TextView 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:" />< Button 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" />< /RelativeLayout>

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：

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

< ?xml version="1.0" encoding="utf-8"?> < manifest xmlns:androclass="http://schemas.android.com/apk/res/android" package="com.example.sendsms" android:versionCode="1" android:versionName="1.0" >< uses-sdk android:minSdkVersion="8" android:targetSdkVersion="16" />< uses-permission android:name="android.permission.SEND_SMS"/>< uses-permission android:name="android.permission.RECEIVE_SMS"/>< application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > < activity android:name="com.example.sendsms.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>

活动类【如何在android中发送短信】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：
