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. }
8. public void setPowerManager(PowerManager powerManager) {
9. this.powerManager = powerManager;
10. }
12. public KeyguardLock getKeyguardLock() {
13. return keyguardLock;
14. }
16. public void setKeyguardLock(KeyguardLock keyguardLock) {
17. this.keyguardLock = keyguardLock;
18. }
20. private KeyguardLock keyguardLock ;
21. public Against getAgainst() {
22. return against;
23. }
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("");
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 ;
6. against= ((SaveSth)getApplication()).getAgainstTheft();
7. pm= ((SaveSth)getApplication()).getPowerManager();
8. keyguardLock=((SaveSth)getApplication()).getKeyguardLock();
