android系统添加手机重启reboot选项

阅读更多

都是修改framework下面的文件：

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

在items中添加如下参考代码,表示在系统power菜单中添加一个“重启”选项以及响应reboot事件：

 

new SinglePressAction(
                        com.android.internal.R.drawable.ic_lock_power_off,
                        R.string.global_action_power_reboot) {

                    public void onPress() {
                        ShutdownThread.reboot(mContext, null, true);
                    }

                    public boolean showDuringKeyguard() {
                        return true;
                    }

                    public boolean showBeforeProvisioning() {
                        return true;
                    }
                });

 

2、 在com.android.internal.app.ShutdownThread类中添加相应的重启reboot处理事件。

类似于下面的代码：

/**
     * Request a clean shutdown, waiting for subsystems to clean up their
     * state etc.  Must be called from a Looper thread in which its UI
     * is shown.
     *
     * @param context Context used to display the shutdown progress dialog.
     * @param confirm true if user confirmation is needed before shutting down.
     * @param isReboot true if user confirmation is needed reboot and not shutdown.
     */
    public static void shutdown(final Context context, boolean confirm,boolean isReboot) {
    	mReboot = isReboot ;
        // ensure that only one thread is trying to power down.
        // any additional calls are just returned
        synchronized (sIsStartedGuard) {
            if (sIsStarted) {
                Log.d(TAG, "Request to shutdown already running, returning.");
                return;
            }
        }

        Log.d(TAG, "Notifying thread to start radio shutdown");

        if (confirm) {
            final AlertDialog dialog = new AlertDialog.Builder(context)
                    .setIcon(android.R.drawable.ic_dialog_alert)
                    .setTitle(mReboot?com.android.internal.R.string.global_action_power_reboot:com.android.internal.R.string.global_action_power_off)
                    .setMessage(mReboot?com.android.internal.R.string.reboot_confirm:com.android.internal.R.string.shutdown_confirm)
                    .setPositiveButton(com.android.internal.R.string.yes, new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            beginShutdownSequence(context);
                        }
                    })
                    .setNegativeButton(com.android.internal.R.string.no, null)
                    .create();
            dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD_DIALOG);
            if (!context.getResources().getBoolean(
                    com.android.internal.R.bool.config_sf_slowBlur)) {
                dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND);
            }
            dialog.show();
        } else {
            beginShutdownSequence(context);
        }
    }
