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！
