    runnable = new Runnable() {

        }
    };


}

public void setTextMeesage(String meesage) {
    notificationView.setTextMessage(meesage);
    //  Toast.makeText(InboxNotificationManager.this, "", Toast.LENGTH_SHORT).show();


}

public void showInboxNotification(String message) {
    if (notificationView.getWindowToken() == null) {
        mWindowManager.addView(notificationView, mWindowParams);
        notificationView.startAnimation();
        setTextMeesage(message);

    } else {
        // mWindowManager.setText(count);

    }
    notificationView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            notificationView.stopAnimation(animationListener);

        }
    });

    handler.removeCallbacks(runnable);
    handler.postDelayed(runnable, 3000);


}

public void hideInboxNotification() {
    if (notificationView.getWindowToken() != null) {
        mWindowManager.removeView(notificationView);
    }


}

当我使用这个课程时

InboxNotificationManager.Instance(BaseActivity.this).showInboxNotification("Hello world");

谢谢你，对不起，我的英文不好 .
