Android电量和插拔电源状态广播监听_android插上电池监听

Android电量和插拔电源状态广播监听

Android电量广播状态有3种，电量低，电量充满，电量发生改变。
Action是：

Intent.ACTION_BATTERY_CHANGE
Intent.ACTION_BATTERY_LOW
Intent.ACTION_BATTERY_OKAY

示例代码：

public class BatteryListener {

    private Context mContext;

    private BatteryBroadcastReceiver receiver;

    private BatteryStateListener mBatteryStateListener;

    public BatteryListener(Context context) {
        mContext = context;

MainActivity中调用：

public class MainActivity extends AppCompatActivity {

    private BatteryListener listener;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
