Android源码开发之长按power键添加GlobalActions

来源：互联网发布：东京著衣淘宝上没有了编辑：程序博客网时间：2024/05/17 06:14

应客户需求，开发一个长按power键，弹出截图的菜单，原本按power键只会弹出关机和重启、飞行模式等。

1.找到frameworks/base/core/res/res/values/config.xml

添加数组

<string-array translatable="false" name="config_globalActionsList">
<item>power</item>
<item>reboot</item>
<item>airplane</item>
<item>screenshot</item>
</string-array>

2.找到frameworks/base/policy/src/com/android/internal/policy/impl/GlobalActions.java

添加GlobalActions

private static final String GLOBAL_ACTION_KEY_SCREEN_SHOT = "screenshot";

--------

private GlobalActionsDialog createDialog() {

---------------

else if (GLOBAL_ACTION_KEY_AIRPLANE.equals(actionKey)) {
mItems.add(mAirplaneModeOn);
}else if(GLOBAL_ACTION_KEY_SCREEN_SHOT.equals(actionKey)){
mItems.add(getScreenShotActions());
}

------------

//添加action

private Action getScreenShotAction(){
return new SinglePressAction(
com.android.internal.R.drawable.ic_screenshot,
R.string.global_screenshot) {

public void onPress() {
mWindowManagerFuncs.ScreenShot();//回调截图
}
public boolean onLongPress() {
return true;
}
public boolean showDuringKeyguard() {
return true;
}
public boolean showBeforeProvisioning() {
return true;
}
};
}

具体mWindowManagerFuncs.ScreenShot();回调的实现需要读者去实现
