这里是主要代码资源我打包，自己下资源，放到这里写图片描述

  @Override        protected void onResume() {            super.onResume();            register();        }        @Override        protected void onPause() {            super.onPause();            unregister();        }        private void register() {            registerReceiver(batteryChangedReceiver,  new IntentFilter(Intent.ACTION_BATTERY_CHANGED));        }        private void unregister() {            unregisterReceiver(batteryChangedReceiver);        }        // 接受广播        private BroadcastReceiver batteryChangedReceiver = new BroadcastReceiver() {            public void onReceive(Context context, Intent intent) {                if (Intent.ACTION_BATTERY_CHANGED.equals(intent.getAction())) {                    int status = intent.getIntExtra("status", 0);                     int level = intent.getIntExtra("level", 0);                    int scale = intent.getIntExtra("scale", 100);                    int power = level * 100 / scale;                    Log.d("Deom", "电池电量：:" + power);                     switch (status) {                          case BatteryManager.BATTERY_STATUS_UNKNOWN:                              break;                          case BatteryManager.BATTERY_STATUS_CHARGING:                              showMessage("充电");                           mBatteryView.setImageResource(R.drawable.stat_sys_battery_charge);                              mBatteryView.getDrawable().setLevel(level);                              break;                          case BatteryManager.BATTERY_STATUS_DISCHARGING:                              showMessage(level+"");                           mBatteryView.setImageResource(R.drawable.stat_sys_battery);                              mBatteryView.getDrawable().setLevel(level);                              break;                          case BatteryManager.BATTERY_STATUS_NOT_CHARGING:                              break;                          case BatteryManager.BATTERY_STATUS_FULL:                              break;                          }   //                  mBatteryView.setPower(power);                }            }        };

布局里面放一个

  <ImageView            android:id="@+id/battery_view"            android:layout_width="0px"            android:layout_height="match_parent"            android:layout_weight="1"            android:layout_marginRight="100px" />

运行就ok了,图片资源 http://download.csdn.net/detail/u012922981/9673188
