Android自定义短信接受弹框提示

（1）开启一个service,注册一个广播接收器，在onReceive中监听短信接受
（2）新建一个窗口，显示自定义布局

public class SmsService extends Service implements View.OnClickListener {    private SmsReceiver smsReceiver;    //发件人号码    private String smsPhone;    //短信内容    private String smsContent;    //窗口管理    private WindowManager wm;

自定义布局

public class DispatchLinearLayout extends LinearLayout {    private DispatchKeyEventListener dispatchKeyEventListener;    public DispatchLinearLayout(Context context, AttributeSet attrs) {        super(context, attrs);    }    public DispatchLinearLayout(Context context) {        super(context);    }    public DispatchLinearLayout(Context context, AttributeSet attrs, int defStyleAttr) {        super(context, attrs, defStyleAttr);    }    public DispatchKeyEventListener getDispatchKeyEventListener() {        return dispatchKeyEventListener;    }    public void setDispatchKeyEventListener(DispatchKeyEventListener dispatchKeyEventListener) {        this.dispatchKeyEventListener = dispatchKeyEventListener;    }    //接口    public static interface DispatchKeyEventListener {        boolean dispatchKeyEvent(KeyEvent event);    }    @Override    public boolean dispatchKeyEvent(KeyEvent event) {        //如果不为空 说明调用了 去获取事件        if (dispatchKeyEventListener != null) {            return dispatchKeyEventListener.dispatchKeyEvent(event);        }        return super.dispatchKeyEvent(event);    }}
