Android在关机界面添加重启功能
Google原生的Android系统一般是没有“重启”这个选项的。有时候重启也是不可或缺的一个Feature，那么如何在源码环境下添加这个选项呢？
1. 在frameworks\base\core\res\res\values\strings.xml
中添加标签:
<span style="font-size:14px;"><!--zms add start--> <!-- label for item that power reboot in phone options dialog --> <string name="zzzzz_global_action_power_reboot">Reboot</string> <!--zms add end--></span>
当然这只是英语语系的,需要添加其它语系的标示,把"Reboot" 替换成其它语言。
2. 在alps\frameworks\base\core\res\res\drawable-hdpi 中添加图标:
zzzzz_ic_lock_power_reboot.png
3. 打开frameworks\policies\base\phone\com\android\internal\policy\impl\GlobalActions.java
大概在这个文件的261行有这样的代码:
mItems = Lists.newArrayList( // silent mode mSilentModeToggle, // next: airplane mode mAirplaneModeOn, // last: power off
在这里,我们添加power reboot 的新的item.
具体这个mItems 更新为如下:
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;
}
}//zms add start
,
new SinglePressAction(
com.android.internal.R.drawable.zzzzz_ic_lock_power_reboot,
R.string.zzzzz_global_action_power_reboot) {
public void onPress() {
// reboot by making sure radio and power are handled
accordingly.
ShutdownThread.reboot(mContext, null, true);
}
public boolean showDuringKeyguard() {
return true;
}
public boolean showBeforeProvisioning() {
return true;
}
}
//zms add end.
); 经过这样的添加/修改后,这项feature 即可运行。
注意如果测试的话,因为有修改framework 中的文件,最好new 一下整个工程。
另外还需要修改一下ShutdownThread.java 中的那个dialog 显示描述,不然将依旧看到“关机”的信息。
