1-要寫androidx.才可以用
2-Notofication要說到channel

2022/2/更新Notofication
Notofication-

通常會和推播一起使用，在app條顯示的資料，跳出通知!

先新增檔案-

綁定onClick之後再改成-showNotification

看到JAVA檔-發通知-接受-

請求碼=比對用

package com.huang.mynotofication;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.view.View;

public class MainActivity extends AppCompatActivity {

    //宣告變數
    static final int REQUEST_CODE = 300;//請求碼
    static final String NOTIFY_ID = "abc";//識別碼

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void showNotification(View view) {
    }
}

打入舊的會帶入新的~

目前的程式碼:

IMPORTANCE_DEFAULT -->高級通知

IMPORTANCE_DEFAULT：預設的重要性，不會彈出提醒，可以發出音效及震動，顯示在狀態欄及展開的通知欄中。 IMPORTANCE_HIGH：重要性高，會彈出提醒，可以發出音效

有發現模擬器不會動居然是(因為新版本的顏色要用#.......的方法)

android:text="好吃便當訂購表"
        android:textColor="@color/design_default_color_error"

的顏色讀不出來..所以就是點顏色的地方選顏色後就可以顯示了

數量->選number 的bottom
小計先寫0元->等計算完會改變

加入送出/取消

到java檔

package com.huang.myui4_form;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.view.View;

public class MainActivity extends AppCompatActivity {
    
    

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
    
    public void onClick(View view){
        
    }
    
}

先寫變數

EditText uName, uPhone, uNum;
    TextView uPrice;
    RadioGroup uMeal, uDrink;
    RadioButton m1,m2,m3,m4, d1,d2,d3;
    CheckBox memo1,memo2,memo3;
    String mealString, drinkString, all="";

全部長成這樣

package com.huang.myui4_form;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.view.View;

public class MainActivity extends AppCompatActivity {



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void onClick(View view){

    }

}

先產生一個第2頁讓送出可以動作
