Android应用程序：如何更改电池的百分比？

Question

我想访问电池详情，以便我可以更改它。 例如，显示80％的电量而不是50％。

如何在我的代码中访问该代码？

在此先感谢！ Dvir

private Handler handler = new Handler; 

private BroadcastReceiver mBatInfoReceiver = new BroadcastReceiver() { 
    @Override 
    public void onReceive(final Context context, Intent intent) { 
     int level = intent.getIntExtra(BatteryMenter code hereanager.EXTRA_LEVEL, 0); 
     int scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, 100); 
     Log.i(TAG, "level: " + level + "; scale: " + scale); 
     int percent = (level*100)/scale; 

     final String text = String.valueOf(percent) + "%";enter code here 
     handler.post(new Runnable() { 

      public void run() { 
       Toast.makeText(context, text, Toast.LENGTH_SHORT).show(); 
      } 
     }); 

    } 
};
