        Notification noti = new Notification.Builder(mContext)
                .setTicker
 
("名稱")

                .setContentText("時間")
                .setSmallIcon(R.drawable.app_icon)//設定圖示
                .setAutoCancel(true)//點選之後消失
                .setDefaults(Notification.DEFAULT_SOUND)//設定聲音
                .setContentIntent(pendingIntent)//點選之後的頁面
                .build
 
();
        NotificationManager manager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
        manager.notify(1,noti);//id控制第幾條，相同的id會替換掉上一次的訊息通知

1.主程式碼

        View layoutView =  LayoutInflater.from(context).inflate(R.layout.toast_top, null);
        //設定文字的引數 設定載入文字檔案的引數，必須通過LayoutView獲取。
        TextView timeView = layoutView.findViewById
 
(R.id.tv_assist_toast_time);
        TextView contentView = layoutView.findViewById(R.id.tv_assist_toast_content);
        TextView titletView = layoutView.findViewById(R.id.tv_assist_toast_title);
        timeView.setText("時間");
        titletView.setText("頭部提示");
        contentView.setText("訊息內容");
        WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
        //獲得螢幕的寬度
        int width = wm.getDefaultDisplay().getWidth();
        LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(width, ViewGroup.LayoutParams.WRAP_CONTENT);
        //設定TextView的寬度為 螢幕寬度
        layoutView.setLayoutParams(layoutParams);
        //獲得螢幕的寬度
        //建立toast物件，
        Toast toast = new Toast(context);
        //把要Toast的佈局檔案放到toast的物件中
        toast.setView(layoutView);
        toast.setDuration(toast.LENGTH_LONG);
        toast.setGravity(Gravity.TOP, 0, 0);
        toast.getView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);//設定Toast可以佈局到系統狀態列的下面
        toast.show();
