Android系統添加手機重啟reboot選項

都是修改framework下面的文件：

1、com.Android.internal.policy.impl.GlobalActions

在items中添加如下參考代碼,表示在系統power菜單中添加一個“重啟”選項以及響應reboot事件：

1. new SinglePressAction(
2. com.android.internal.R.drawable.ic_lock_power_off,
3. R.string.global_action_power_reboot) {
5. public void onPress() {
6. ShutdownThread.reboot(mContext, null, true);
7. }
9. public boolean showDuringKeyguard() {
10. return true;
11. }
13. public boolean showBeforeProvisioning() {
14. return true;
15. }
16. });

2、 在com.android.internal.app.ShutdownThread類中添加相應的重啟reboot處理事件。

類似於下面的代碼：

1. /**
2. * Request a clean shutdown, waiting for subsystems to clean up their
3. * state etc. Must be called from a Looper thread in which its UI
4. * is shown.
5. *
6. * @param context Context used to display the shutdown progress dialog.
7. * @param confirm true if user confirmation is needed before shutting down.
8. * @param isReboot true if user confirmation is needed reboot and not shutdown.
9. */
10. public static void shutdown(final Context context, boolean confirm,boolean isReboot) {
11. mReboot = isReboot ;
12. // ensure that only one thread is trying to power down.
13. // any additional calls are just returned
14. synchronized (sIsStartedGuard) {
15. if (sIsStarted) {
16. Log.d(TAG, "Request to shutdown already running, returning.");
17. return;
18. }
19. }
21. Log.d(TAG, "Notifying thread to start radio shutdown");
23. if (confirm) {
24. final AlertDialog dialog = new AlertDialog.Builder(context)
25. .setIcon(android.R.drawable.ic_dialog_alert)
26. .setTitle(mReboot?com.android.internal.R.string.global_action_power_reboot:com.android.internal.R.string.global_action_power_off)
27. .setMessage(mReboot?com.android.internal.R.string.reboot_confirm:com.android.internal.R.string.shutdown_confirm)
28. .setPositiveButton(com.android.internal.R.string.yes, new DialogInterface.OnClickListener() {
29. public void onClick(DialogInterface dialog, int which) {
30. beginShutdownSequence(context);
31. }
32. })
33. .setNegativeButton(com.android.internal.R.string.no, null)
34. .create();
35. dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD_DIALOG);
36. if (!context.getResources().getBoolean(
37. com.android.internal.R.bool.config_sf_slowBlur)) {
38. dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND);
39. }
40. dialog.show();
41. } else {
42. beginShutdownSequence(context);
43. }
44. }
