真希望天天都是星期天之 AlertDialog & CheckBox

星期天不是錯啦!不過好像星期六更好，因為明天還是繼續放假，來吧!利用AlertDialog弄個一週的CheckBox清單吧，把想放假的那幾天勾起來。


1. 建立專案

2. 加個TextView & Button

3.  Source Code

     重點就是String[] & boolean[]最好一樣，如果不一樣，嘿嘿，這麼簡單還要教，自己試試看。

package com.example.ex003; import android.os.Bundle; import android.app.Activity; import android.app.AlertDialog; import android.content.DialogInterface; import android.view.Menu; import android.view.View; import android.widget.Button; import android.widget.TextView; public class MainActivity extends Activity {           private String[] week = {"星期一", "星期二", "星期三", "星期四", "星期五", "星期六", "星期日"};      private boolean[] bweek = {false,false,false,false,false,false,false};      private TextView tv1;      private Button btn1;      private String repeat = "";          @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);         tv1 = (TextView) MainActivity.this.findViewById(R.id.textView1);         btn1 = (Button) MainActivity.this.findViewById(R.id.button1);                 btn1.setOnClickListener(new Button.OnClickListener()         {               @Override               public void onClick(View v) {                   // TODO Auto-generated method stub                   repeat = "";                   new AlertDialog.Builder(MainActivity.this)                   .setTitle("EX003")                   .setMultiChoiceItems(                            week,                            bweek,                            new DialogInterface.OnMultiChoiceClickListener() {                                               @Override                        public void onClick(DialogInterface dialog, int which, boolean isChecked) {                            // TODO Auto-generated method stub                                                   }                   })                   .setPositiveButton("OK", new DialogInterface.OnClickListener() {                                               @Override                        public void onClick(DialogInterface dialog, int which) {                            // TODO Auto-generated method stub                            for (int i = 0; i < bweek.length; i++) {                                 if (bweek[i]) {                                      repeat = repeat + week[i];                                 }                            }                            tv1.setText(repeat);                        }                   })                   .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {                                               @Override                        public void onClick(DialogInterface dialog, int which) {                            // TODO Auto-generated method stub                                                   }                   }).show();                                 }          });     } }

 4.  就是這個單，就是這個單

5. 搞定了，收工嗎?

6. 專業專業，菜鳥新上手，當然給老闆要有物超所值的fu，若全勾了，就來個每天

 

7. Source Code

package com.example.ex003; import android.os.Bundle; import android.app.Activity; import android.app.AlertDialog; import android.content.DialogInterface; import android.view.Menu; import android.view.View; import android.widget.Button; import android.widget.TextView; public class MainActivity extends Activity {           private String[] week = {"星期一", "星期二", "星期三", "星期四", "星期五", "星期六", "星期日"};      private boolean[] bweek = {false,false,false,false,false,false,false};      private TextView tv1;      private Button btn1;      private String repeat = "";          @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);         tv1 = (TextView) MainActivity.this.findViewById(R.id.textView1);         btn1 = (Button) MainActivity.this.findViewById(R.id.button1);                 btn1.setOnClickListener(new Button.OnClickListener()         {               @Override               public void onClick(View v) {                   // TODO Auto-generated method stub                   repeat = "";                   new AlertDialog.Builder(MainActivity.this)                   .setTitle("EX003")                   .setMultiChoiceItems(                            week,                            bweek,                            new DialogInterface.OnMultiChoiceClickListener() {                                               @Override                        public void onClick(DialogInterface dialog, int which, boolean isChecked) {                            // TODO Auto-generated method stub                                                   }                   })                   .setPositiveButton("OK", new DialogInterface.OnClickListener() {                                               @Override                        public void onClick(DialogInterface dialog, int which) {                            // TODO Auto-generated method stub //                         for (int i = 0; i < bweek.length; i++) { //                              if (bweek[i]) { //                                   repeat = repeat + week[i]; //                              } //                         }                            chkday();                            tv1.setText(repeat);                        }                   })                   .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {                                               @Override                        public void onClick(DialogInterface dialog, int which) {                            // TODO Auto-generated method stub                                                   }                   }).show();                                 }          });     }     private void chkday(){       int everyday = 0;          for (int i = 0; i < bweek.length; i++) {               if (bweek[i]) {                   repeat = repeat + week[i];                   everyday++;               }          }                   if (everyday == 7)               repeat = "每日";     }     }

 

這是我的一小步，也是人類的一小步，不過多寫一點，以後就可以剪下貼上，然後早點回家...............................................，嗯，吃完早餐再回家，老闆 來個燒餅油條加豆漿!!!
