//静态注册

<receiver
    android:name=".receiver.MyMediaButtonReceiver"
    android:enabled="true"
    android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.MEDIA_BUTTON" />
    </intent-filter>
</receiver>

//接收广播

            Log.e(TAG, "keyEvent==" +keyEvent);
            switch (keyEvent.getKeyCode()) {
                case KeyEvent.KEYCODE_HEADSETHOOK:
                    Toast.makeText(context, "hook",Toast.LENGTH_SHORT).show();
