Android上的按钮，TextView的显示器阵列 [英] Display array on Android button and textview
本文介绍了Android上的按钮，TextView的显示器阵列的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我目前做多的Android问答游戏，但我如何显示上的按钮上一个TextView所有六个问题和四个答案就有点糊涂了？此外，林不知道如何搭配Android中正确/不正确的答案（因为它涉及到Android的语法）。
PS：当玩家preSS按钮是其正确不正确的球员将移动到下一个新的问题+答案，这将是可能的，如果我想保存在TXT文件中的问题和答案
这是我迄今所做的......

解决方案
使用单选按钮来选择正确的答案，并使用按钮进入下一个问题！
优点
- 从一个活动到其他的运动将更加真实（好像翻页）
- 给移动一个级别的感觉！ ;）
- 最重要更容易实现（嗯，我觉得它更容易这样）
XML code的活动布局：
＆LT;的RelativeLayout的xmlns：机器人=http://schemas.android.com/apk/res/android
的xmlns：工具=http://schemas.android.com/tools
机器人：layout_width =match_parent
机器人：layout_height =match_parent
机器人：paddingBottom会=@扪/ activity_vertical_margin
机器人：paddingLeft =@扪/ activity_horizontal_margin
机器人：paddingRight =@扪/ activity_horizontal_margin
机器人：paddingTop =@扪/ activity_vertical_margin
工具：上下文=com.stackoverflow.MainActivity＆GT;＆LT;的TextView
机器人：ID =@ + ID / textView1
机器人：layout_width =WRAP_CONTENT
机器人：layout_height =WRAP_CONTENT
机器人：文字=@字符串/参考hello world/＆GT;
＆LT; RadioGroup中
机器人：ID =@ + ID / rad_btn_group1
机器人：layout_width =WRAP_CONTENT
机器人：layout_height =WRAP_CONTENT
安卓的onClick =onRadioButtonClicked＆GT;
＆LT;单选
机器人：ID =@ + ID / radioButton4
机器人：layout_width =WRAP_CONTENT
机器人：layout_height =WRAP_CONTENT
机器人：layout_marginTop =16DP
机器人：文字=@字符串/ radio_button1/＆GT;＆LT;单选
机器人：ID =@ + ID / radioButton1
机器人：layout_width =WRAP_CONTENT
机器人：layout_height =WRAP_CONTENT
机器人：layout_marginTop =21dp
机器人：文字=@字符串/ radio_button2/＆GT;＆LT;单选
机器人：ID =@ + ID / radioButton2
机器人：layout_width =WRAP_CONTENT
机器人：layout_height =WRAP_CONTENT
机器人：layout_marginTop =21dp
机器人：文字=@字符串/ radio_button3/＆GT;＆LT;单选
机器人：ID =@ + ID / radioButton3
机器人：layout_width =WRAP_CONTENT
机器人：layout_height =WRAP_CONTENT
机器人：文字=@字符串/ radio_button4
机器人：layout_marginTop =21dp/＆GT;＆LT;按钮
机器人：ID =@ + ID /按钮1
机器人：layout_width =WRAP_CONTENT
机器人：layout_height =WRAP_CONTENT
机器人：layout_marginTop =21dp
机器人：文字=@字符串/ btn_submit/＆GT;＆LT; / RadioGroup中＆GT;＆LT; / RelativeLayout的＆GT;
的Java code为游戏逻辑如下：
公共类MainActivity扩展活动实现OnClickListener {
按钮BTN;
RadioGroup中selectionGroup;
公共静态INT得分= 0; //访问它在其他类以及以++或 -
布尔answerAttempt = FALSE; //惩罚玩家改变的答案;）@覆盖
保护无效的onCreate（捆绑savedInstanceState）{
super.onCreate（savedInstanceState）;
的setContentView（R.layout.activity_main）; BTN =（按钮）findViewById（R.id.button1）;
btn.setOnClickListener（本）;
selectionGroup =（RadioGroup中）findViewById（R.id.rad_btn_group1）;
selectionGroup.setOnCheckedChangeListener（新OnCheckedChangeListener（）{ @覆盖
公共无效onCheckedChanged（RadioGroup中组，诠释checkedId）{
// TODO自动生成方法存根
//因为我们知道radiobutton3是包含了正确的答案:)
如果（answerAttempt）
{
得分 - = 2;
}
否则，如果（R.id.radioButton3 == checkedId＆放大器;＆安培;！answerAttempt）
{
++分;
answerAttempt = TRUE; //这意味着第一次尝试是由玩家制作
}
其他
{
- 得分了;
answerAttempt = TRUE; //这意味着第一次尝试是由玩家制作
} }
}）;
}@覆盖
公共无效的onClick（视图v）{
// TODO自动生成方法存根
开关（v.getId（））//这是按钮的ID点击（在我们的案例提交按钮）
{
案例R.id.button1：//这是XML提交按钮的id
//从这里开始另一项活动上的另一个活动下一个问题:) 打破;
}}
}
修改
code自动将下一个活动
电子@覆盖
公共无效onCheckedChanged（RadioGroup中组，诠释checkedId）{
// TODO自动生成方法存根
//因为我们知道radiobutton3是包含了正确的答案:)
如果（R.id.radioButton3 == checkedId）
{
++分;
//转到下一个问题:)
startActivity（新意图（getBaseContext（），next_question_activity.class））; }
其他
{
//转到下一个问题困扰没有将比分:)
startActivity（新意图（getBaseContext（），next_question_activity.class））; } }
}）;
i am currently doing Android multiple quiz game but i am a bit confused on how to display all the six Questions on a TextView and four Answers on Buttons? also, im not sure how to match the correct/incorrect answer in Android (because it involves Android Syntax).
PS: when player press the button whether its correct of incorrect player will move to the next new questions +answers and would it be possible if i want to store the questions and answers on txt file?
here is what i have done so far...
public class play extends Activity implements OnClickListener {
private int correctanswers;
private TextView questionstextview;
private TextView questionnumber;
private TextView playerfeedback;
private int totalanswer;
private int score;
private List<Question> QuestionList;
Button answer1,answer2,answer3,answer4;
Button AnswerButtons [] = {answer1,answer2,answer3,answer4};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.play);
QuestionList = new ArrayList<Question>();
ArrayList <String> answer = new ArrayList<String>();
answer.add("8");
answer.add("9");
answer.add("3");
answer.add("1");
QuestionList.add(new Question("what is 4+4", answer, 0));
answer.add("17");
answer.add("20");
answer.add("15");
answer.add("14");
QuestionList.add(new Question("what is 7+8?", answer, 3));
answer.add("20");
answer.add("30");
answer.add("19");
answer.add("34");
QuestionList.add(new Question("what is 10+10?", answer, 0));
answer.add("12");
answer.add("11");
answer.add("13");
answer.add("14");
QuestionList.add(new Question("what is 6+6?", answer, 0));
answer.add("6");
answer.add("5");
answer.add("4");
answer.add("7");
QuestionList.add(new Question("what is 4+3?", answer, 3));
answer.add("7");
answer.add("9");
answer.add("10");
answer.add("11");
QuestionList.add(new Question("what is 3+7?", answer, 2));
questionstextview = (TextView) findViewById (R.id.questionstextview);
questionnumber = (TextView) findViewById (R.id.questionnumber);
View AnswerButton1 = findViewById(R.id.answerbutton1);
AnswerButton1.setOnClickListener(this);
View AnswerButton2 = findViewById(R.id.answerbutton2);
AnswerButton2.setOnClickListener(this);
View AnswerButton3 = findViewById(R.id.answerbutton3);
AnswerButton3.setOnClickListener(this);
View AnswerButton4 = findViewById(R.id.answerbutton4);
AnswerButton4.setOnClickListener(this);
}
private void ButtonPress (Button answerButton){
}
public play() {
}
@Override
public void onClick(View v) {
}
解决方案
use Radio buttons for selecting the right answer and use the button to proceed to the next question.!
Advantages
- the movement from one activity to other will be more real (as if turning a page)
- gives a feeling of moving one level up !! ;)
- most important of all easier to implement (well i find it easier that way)
xml Code for the activity layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.stackoverflow.MainActivity" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/hello_world" />
<RadioGroup
android:id="@+id/rad_btn_group1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="onRadioButtonClicked" >
<RadioButton
android:id="@+id/radioButton4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
android:text="@string/radio_button1" />
<RadioButton
android:id="@+id/radioButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="21dp"
android:text="@string/radio_button2" />
<RadioButton
android:id="@+id/radioButton2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="21dp"
android:text="@string/radio_button3" />
<RadioButton
android:id="@+id/radioButton3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/radio_button4"
android:layout_marginTop="21dp" />
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="21dp"
android:text="@string/btn_submit" />
</RadioGroup>
</RelativeLayout>
java code for the game logic is as follows:
public class MainActivity extends Activity implements OnClickListener{
Button btn ;
RadioGroup selectionGroup;
public static int score = 0;//to access it in other class as well to ++ or --
boolean answerAttempt = false; //to penalize player changing the answer ;)
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn = (Button) findViewById(R.id.button1);
btn.setOnClickListener(this);
selectionGroup = (RadioGroup) findViewById(R.id.rad_btn_group1);
selectionGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
// TODO Auto-generated method stub
//because we know radiobutton3 is contains the right answer :)
if(answerAttempt)
{
score -= 2;
}
else if (R.id.radioButton3 == checkedId && !answerAttempt)
{
++score;
answerAttempt = true; //meaning first attempt is made by the player
}
else
{
--score;
answerAttempt = true; //meaning first attempt is made by the player
}
}
});
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch(v.getId())//this is the id of the button clicked (in our case submit button)
{
case R.id.button1://this is the id of the submit button in xml
//start another activity from here for next question on another activity :)
break;
}
}
}
Edit
code for automatically going to next activity
e@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
// TODO Auto-generated method stub
//because we know radiobutton3 is contains the right answer :)
if (R.id.radioButton3 == checkedId)
{
++score;
//goes to the next question :)
startActivity(new Intent(getBaseContext(), next_question_activity.class));
}
else
{
//goes to the next question without troubling the score :)
startActivity(new Intent(getBaseContext(), next_question_activity.class));
}
}
});
