Android 將activity中的對象傳遞到service中

Android 將activity中的對象傳遞到service中，首先，寫一個類，這個是保存activity中的對象。在AndroidManifest.xml文件中的<application>標簽中寫入<application android:label="@string/app_name" android:icon="@drawable/icon"android:name=".SaveSth">

1. public class SaveSth extends Application{  
2.     private Against against;  
3.     private PowerManager powerManager;  
4.     public PowerManager getPowerManager() {  
5.         return powerManager;  
6.     }  
7.   
8.     public void setPowerManager(PowerManager powerManager) {  
9.         this.powerManager = powerManager;  
10.     }  
11.   
12.     public KeyguardLock getKeyguardLock() {  
13.         return keyguardLock;  
14.     }  
15.   
16.     public void setKeyguardLock(KeyguardLock keyguardLock) {  
17.         this.keyguardLock = keyguardLock;  
18.     }  
19.   
20.     private KeyguardLock keyguardLock ;  
21.     public Against getAgainst() {  
22.         return against;  
23.     }  
24.   
25.     public void setAgainstTheft(Against against) {  
26.         this.against = against;  
27.     }  
28. }  

1. PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);  
2. KeyguardManager keyguardManager = (KeyguardManager) getSystemService(KEYGUARD_SERVICE);  
3. KeyguardLock keyguardLock = keyguardManager.newKeyguardLock("");  
4.   
5. ((SaveSth)getApplication()).setAgainst(this);  
6. ((SaveSth)getApplication()).setPowerManager(pm);  
7. ((SaveSth)getApplication()).setKeyguardLock(keyguardLock);  

1. private Against against;  
2. PowerManager pm;  
3. PowerManager.WakeLock wakeLock;  
4. KeyguardLock keyguardLock ;  
5.   
6. against= ((SaveSth)getApplication()).getAgainstTheft();  
7. pm= ((SaveSth)getApplication()).getPowerManager();  
8. keyguardLock=((SaveSth)getApplication()).getKeyguardLock();
