繼承自BroadcastReceiver類，需要重寫onReceive方法，當收到短信時就會自動觸發onReceive方法，在onReceive方法中通過Toast來顯示短信內容。

?

?1?public?class?SMSReceiver?extends?BroadcastReceiver
?2?{
?3?????/*當收到短信時，就會觸發此方法*/
?4?????public?void?onReceive(Context?context,?Intent?intent)
?5?????{
?6?????????Bundle?bundle?=?intent.getExtras();
?7?????????Object?messages[]?=?(Object[])?bundle.get("pdus");
?8?????????SmsMessage?smsMessage[]?=?new?SmsMessage[messages.length];
?9?????????for?(int?n?=?0;?n?<?messages.length;?n++)
10?????????{
11?????????????smsMessage[n]?=?SmsMessage.createFromPdu((byte[])?messages[n]);
12?????????}
13?????????//產生一個Toast
14?????????Toast?toast?=?Toast.makeText(context,?"短信內容:?"?+?smsMessage[0].getMessageBody(),?Toast.LENGTH_LONG);
15?????????//設置toast顯示的位置
16?????????toast.setGravity(Gravity.TOP|Gravity.LEFT,?0,?200);
17?????????//顯示該Toast
18?????????toast.show();
19?????}
20?}

?因為在項目中使用了短信接口，所以需要在AndroidManifest.xml中聲明其權限，如橙色高亮顯示：

?

?1?<?xml?version="1.0"?encoding="utf-8"?>
?2?<manifest?xmlns:android="http://schemas.android.com/apk/res/android"
?3???????package="com.yarin.android.Examples_04_05"
?4???????android:versionCode="1"
?5???????android:versionName="1.0">
?6?????<uses-permission?android:name="android.permission.RECEIVE_SMS"></uses-permission>
?7?????<application?android:icon="@drawable/icon"?android:label="@string/app_name">
?8?????????<activity?android:name=".Activity01"
?9???????????????????android:label="@string/app_name">
10?????????????<intent-filter>
11?????????????????<action?android:name="android.intent.action.MAIN"/>
12?????????????????<category?android:name="android.intent.category.LAUNCHER"/>
13?????????????</intent-filter>
14?????????</activity>
15?????<receiver?android:name=".SMSReceiver"?android:enabled="true">??
16?????????<intent-filter>??
17?????????????<action?android:name="android.provider.Telephony.SMS_RECEIVED"/>??
18?????????</intent-filter>??
19?????</receiver>?
20?????</application>
21?????<uses-sdk?android:minSdkVersion="5"?/>
22?</manifest>?
23?
