frameworks/base/core/res/res/values/symbols.xml中添加xiguatong id,Otherwise, the resource cannot be referenced

  <java-symbol type="string" name="status_bar_xiguatong" />
  <java-symbol type="string" name="status_bar_battery" />

systemui部分
vendor/mediatek/proprietary/packages/apps/SystemUI/src/com/android/systemui/statusbar/phone/PhoneStatusBarPolicy.java

private final StatusBarIconController mIconController;//Status bar icon controller
//Add your own watermelon bucket icon
private final String mXiGuaTong;
private boolean mXiGuaTongVisible;
@Inject
public PhoneStatusBarPolicy(...){
    
	...
	//
	mXiGuaTong = resources.getString(com.android.internal.R.string.status_bar_xiguatong);
	mXiGuaTongVisible = true;
	...
}
public void init() {
    
	...
	//xiGuaTong:字符串,图片,button description
	mIconController.setIcon(mXiGuaTong, R.drawable.stat_sys_xiguatong,null);
	//Set the picture to be visible or not:字符串,Boolean值
	mIconController.setIconVisibility(mXiGuaTong, mXiGuaTongVisible);
	...
}
