用DatePickerDialog和TimePickerDialog 類別建立日期和時間交談窗 //20170124 劉彥廷 //AlertDialgo(加入日期和時間交談窗) MainActivity.java package com.example.user.myapplication44; import android.app.DatePickerDialog; import android.app.TimePickerDialog; import android.icu.util.Calendar; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.DatePicker; import android.widget.TextView; import android.widget.TimePicker; public class MainActivity extends AppCompatActivity         implements View.OnClickListener,         DatePickerDialog.OnDateSetListener,         TimePickerDialog.OnTimeSetListener{      Calendar c = Calendar.getInstance();        TextView txDate,txTime;     @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);         txDate = (TextView)findViewById(R.id.textView1);

 这次还是留下记录吧。 打开build.gradle文件，修改defaultConfig中的minSdkVersion值为所需要的级别就ok了。 android {     compileSdkVersion 19     buildToolsVersion "19.0.1"     defaultConfig {         minSdkVersion 11         targetSdkVersion 16         versionCode 1         versionName "1.0"     }     buildTypes {         release {             runProguard false             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'         }     } }

這個是AlertDialog練習 ，在交談窗中加入按鈕! 在這之中最多加入三個按鈕,否(Negative)中性(Neutral)及是(Positive) 加入的方法為setXxxButton() 而其中的Xxx分別為Negativity   Neutral    positive //AlertDialog練習在交談窗中加入按鈕 //20170124 劉彥廷  MainActivity.java package com.example.user.myapplication41; import android.content.DialogInterface; import android.support.v7.app.AlertDialog; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.widget.TextView; public class MainActivity extends AppCompatActivity implements DialogInterface.OnClickListener {     TextView txv;     @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);         txv = (TextView)findViewById(R.id.answer);         new AlertDialog.Builder(this)                 .setMessage("你喜歡使用這支手機嗎?")                 .setCancelable(false)                 .setIcon(android.R.drawable.ic_menu_edit)                 .se

這個Toast 顯示方式，有兩種出現時間可以選 LENGTH_SHORT顯示2秒和 LENGTH_LONG顯示3.5秒（程式碼為黃色） 但如果要讓顯示可以立即顯示，那麼程式碼如紅色字體那段 //用Toast顯示答案 猜謎No38 //20170120 劉彥廷 package com.example.user.myapplication38; MainActivity.java import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.AdapterView; import android.widget.ArrayAdapter; import android.widget.ListView; import android.widget.Toast; public class MainActivity extends AppCompatActivity     implements AdapterView.OnItemClickListener{     String[] queArr = {"什麼門永遠關不上?","什麼東西沒人愛吃?","什麼瓜不能吃?","什麼布切不斷?"                ,"什麼屬最愛乾淨?","偷什麼不犯法?"};     String[] ansArr = {"球門","吃虧","傻瓜","瀑布","環保署","偷笑"};     ListView lv;     ArrayAdapter<String> adapter;     @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstance
