[移动开发]Android 10 SystemUI中实现移动数据打开和关闭功能

需求：实现移动数据打开和关闭功能
代码路径：
frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/policy/NetworkController.java
frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/policy/NetworkControllerImpl.java
1、初始化网络和移动数据控制

import com.android.systemui.statusbar.policy.NetworkController;
import com.android.settingslib.net.DataUsageController;

private NetworkController mNTController;
private DataUsageController mDataUsageController;

private void init(Context context) {
   this.mContext = context;
   mNTController = Dependency.get(NetworkController.class);
   mDataUsageController = mNTController.getMobileDataController();
}

2、控制移动数据打开和关闭接口

public void setMobileDataEnable(boolean enabled) {
   if (null != mDataUsageController) {
      mDataUsageController.setMobileDataEnabled(enabled);
   }
}

3、获取当前移动数据是否打开

private boolean isMobileDataEnable() {
   if (null != mDataUsageController) {
      return mDataUsageController.isMobileDataEnabled();
   }
   return false;
}

4、当前是否支持移动数据功能

private boolean isMobileDataSupported() {
   if (null != mDataUsageController) {
      return mDataUsageController.isMobileDataSupported();
   }
   return false;
}

5、如何监听移动数据打开关闭状态，需要实现DataUsageController.NetworkNameProvider接口并且实现里面getMobileDataNetworkName方法

public class MyContainer extends LinearLayout  implements View.OnClickListener,  DataUsageController.NetworkNameProvider{
mDataUsageController.setNetworkController(this);
// TODO: Find a way to move this into DataUsageController.
mDataUsageController.setCallback(new DataUsageController.Callback() {
   @Override
   public void onMobileDataEnabled(boolean enabled) {
      Log.i(TAG, "onMobileDataEnabled() enabled = " + enabled);
      mHandler.post(new Runnable() {

         @Override
         public void run() {
            updateDataStatus(enabled);
         }
      });
   }
});

@Override
public String getMobileDataNetworkName() {
   return "";
}
}
