在自定义控件中注册广播

1、首先new一个广播：

private final BroadcastReceiver mReceiver = new BroadcastReceiver() {    @Override    public void onReceive(Context context, Intent intent) {        if (intent.getAction().equals(Constant.RECEIVER)) {                    }    }};

2、定义一个全局布尔类型的变量：

private boolean mAttached;

3、重写onAttachedToWindow()方法，在里面注册广播

@Overrideprotected void onAttachedToWindow() {    super.onAttachedToWindow();    if (!mAttached) {        mAttached = true;        IntentFilter filter = new IntentFilter();        filter.addAction(Constant.CHANGE_SKIN_RECEIVER);        getContext().registerReceiver(mReceiver, filter);    }}

4、重写onDetachedFromWindow(),在里面注销广播

@Overrideprotected void onDetachedFromWindow() {    super.onDetachedFromWindow();    if (mAttached){        mAttached = false;        getContext().unregisterReceiver(mReceiver);    }}
