android手机有很多的第三方固件，其中有不少固件中有reboot的功能，这个功能是如何实现的呢？我这里会做一个简单的示例。先看一个效果图吧！
如图在dialog中的最后一项是reboot功能。下面看看代码是怎么修改的：
文件路径： frameworks/policies/base/phone/com/android/internal/policy/impl/GlobalActions.java
private AlertDialog createDialog() { .... mItems = Lists.newArrayList( // silent mode mSilentModeToggle, // next: airplane mode mAirplaneModeOn, // last: power off new SinglePressAction( com.android.internal.R.drawable.ic_lock_power_off, R.string.global_action_power_off) { public void onPress() { // shutdown by making sure radio and power are handled accordingly. ShutdownThread.shutdown(mContext, true ); } public boolean showDuringKeyguard() { return true ; } public boolean showBeforeProvisioning() { return true ; } }, // this is add code // last: reboot new SinglePressAction( com.android.internal.R.drawable.ic_lock_power_off, R.string.global_action_reboot) { public void onPress() { // shutdown by making sure radio and power are handled accordingly. ShutdownThread.reboot(mContext, "" , true ); } public boolean showDuringKeyguard() { return true ; } public boolean showBeforeProvisioning() { return true ; } }); mAdapter = new MyAdapter(); .... return dialog; }
代码中ShutdownThread.reboot()方法有三个参数其中第二个参数是一个String，如果这个String是NULL的话，就是正常重启，如果是recovery，系统重启进入recovery mode。R.string.global_action_reboot是我在系统资源文件中添加的字符串。呵呵是不是很简单阿！
