第28天~Notofication
买书
1-要写androidx.才可以用
2-Notofication要说到channel
2022/2/更新Notofication
Notofication-
通常会和推播一起使用，在app条显示的资料，跳出通知!
先新增档案-
绑定onClick之後再改成-showNotification
看到JAVA档-发通知-接受-
请求码=比对用
package com.huang.mynotofication;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends AppCompatActivity {
//宣告变数
static final int REQUEST_CODE = 300;//请求码
static final String NOTIFY_ID = "abc";//识别码
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void showNotification(View view) {
}
}
打入旧的会带入新的~
目前的程序码:
IMPORTANCE_DEFAULT -->高级通知
IMPORTANCE_DEFAULT：预设的重要性，不会弹出提醒，可以发出音效及震动，显示在状态栏及展开的通知栏中。 IMPORTANCE_HIGH：重要性高，会弹出提醒，可以发出音效
package com.huang.mynotofication;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.NotificationCompat;
import android.app.Notification;
import android.app.NotificationChannel;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Build;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends AppCompatActivity {
//宣告变数
static final int REQUEST_CODE = 300;//请求码
static final String NOTIFY_ID = "abc";//识别码
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void showNotification(View view) {
//点通知讯息要如何处理
Intent intent = new Intent(getApplicationContext(), MainActivity.class);
//暂缓执行的Intent
PendingIntent pendingIntent = PendingIntent.getActivity(
getApplicationContext(),
REQUEST_CODE,
intent,
PendingIntent.FLAG_CANCEL_CURRENT
);
//管理器
NotificationManager manager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
//建立+设定通知(内容)物件
Notification.Builder builder = new Notification.Builder(this)
.setContentTitle("好康报报")
.setContentText("口罩。。。")
.setSmallIcon(android.R.drawable.btn_star)
.setDefaults(NotificationCompat.DEFAULT_ALL)
.setContentIntent(pendingIntent);
//Channel
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){//O大写，代表ORIO
NotificationChannel channel = new NotificationChannel(
NOTIFY_ID,
"Test",//tag
NotificationManager.IMPORTANCE_DEFAULT
);
builder.setChannelId(NOTIFY_ID);
manager.createNotificationChannel(channel);
}
//发出通知
manager.notify(100, builder.build());
}
}
目前只有听到声音-用手机试试看
打完就是快要发烧37.2度+手越来越酸=年轻人体质~
下面就是很正式的写CODE
排版的程序码:

有发现模拟器不会动居然是(因为新版本的颜色要用#.......的方法)
android:text="好吃便当订购表"
android:textColor="@color/design_default_color_error"
的颜色读不出来..所以就是点颜色的地方选颜色後就可以显示了

数量->选number 的bottom
小计先写0元->等计算完会改变
加入送出/取消
到java档
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){
}
}
先写变数
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="";
全部长成这样
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){
}
}
先产生一个第2页让送出可以动作
package com.huang.myui4_form;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.CheckBox;
import android.widget.EditText;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
//宣告变数
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="";
//初始化
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
uName = findViewById(R.id.uName);
uPhone = findViewById(R.id.uPhone);
uNum = findViewById(R.id.uNum);
uPrice = findViewById(R.id.uPrice);
//uMeal
uMeal = findViewById(R.id.uMeal);
uMeal.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
RadioButton rb = findViewById(checkedId);
mealString = rb.getText().toString();
Toast.makeText(MainActivity.this,mealString,Toast.LENGTH_SHORT ).show();
}
});
//uDrink
uDrink = findViewById(R.id.uDrink);
uDrink.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
RadioButton rb = findViewById(checkedId);
drinkString = rb.getText().toString();
Toast.makeText(MainActivity.this,drinkString,Toast.LENGTH_SHORT ).show();
}
});
//checkBox
memo1 = findViewById(R.id.memo1);
memo2 = findViewById(R.id.memo2);
memo3 = findViewById(R.id.memo3);
}
//收集资料并送到下一页
public void onClick(View view) {
//文字栏位的收集
String name = uName.getText().toString();
String phone = uPhone.getText().toString();
int num = Integer.parseInt(uNum.getText().toString());
//checkBox
int[] cbs = {R.id.memo1, R.id.memo2, R.id.memo3};
for(int i:cbs){
CheckBox cc = findViewById(i);
if(cc.isChecked()){
all += cc.getText().toString()+"\t";
}
}
//送到第二页
Intent it = new Intent();
it.setClass(MainActivity.this, Page2.class);
//打包资料
startActivity(it);
}
}
