添加onClickListener为在for循环内动态创建的按钮

-3

我有一个RelativeLayout，它允许游戏玩家输入个人详细信息，如姓名并定义他们的角色。布局是根据有多少玩家动态创建的（这在活动前面已经定义）。这全部包含在for循环中以生成每个布局。添加onClickListener为在for循环内动态创建的按钮

我想添加一个onclicklistener，以便每个玩家输入他们的详细信息时，他们的个人数据将被存储。

我到目前为止使用的代码产生了一个ArrayIndexOutOfBoundsException。

你能解释一下我应该如何纠正这段代码，谢谢。

public void buildDynamicViews(Integer input1) { 
     int textId = 10; 
    //Arrays 
    groupDetailsList = (RelativeLayout)findViewById(R.id.playersNameLayout); 
    row_Number = new TextView[input1]; 
    spinnerArray = new Spinner[input1]; 
    groupDetailsContainer = new RelativeLayout[input1]; 
    firstNameText = new TextView[input1]; 
    lastNameText = new TextView[input1]; 
    fNameInput = new EditText[input1]; 
    lNameInput = new EditText[input1]; 
    playerDetailsButton = new Button[input1]; 


    //displays lines of text with instructions 
    text = (TextView)findViewById(R.id.displayMessage); 
    ViewGroup.LayoutParams params = text.getLayoutParams(); 
    params.height = ViewGroup.LayoutParams.WRAP_CONTENT; 
    text.setId(textId); 
    ((MarginLayoutParams) params).setMargins(0,0,0,20); 
    text.setLayoutParams(params); 
    String txt1 = getResources().getString(R.string.player_details_Title);

     playerDetailsButton[i].setWidth(250); 
     playerDetailsButton[i].setHeight(20); 
     playerDetailsButton[i].setText("Press to save details"); 

    //generate OnClick Listener for button 
     PlayerDetailsButtonOnClick = new View.OnClickListener() {

      public void onClick(View v) { 
       String FName = firstNameText[i].toString(); 
       String LName = lastNameText[i].toString(); 
       String fullName = FName+" "+LName; 
       toast(fullName); 

       } 
      }; 


     playerDetailsButton[i].setOnClickListener(PlayerDetailsButtonOnClick); 

     //wrap each view to the layout   
    groupDetailsContainer[i].addView(row_Number[i]); 
     groupDetailsContainer[i].addView(fNameInput[i]); 
     groupDetailsContainer[i].addView(lNameInput[i]); 
     groupDetailsContainer[i].addView(firstNameText[i]); 
     groupDetailsContainer[i].addView(lastNameText[i]); 
     groupDetailsContainer[i].addView(spinnerArray[i]); 
     groupDetailsContainer[i].addView(playerDetailsButton[i]); 
     groupDetailsList.addView(groupDetailsContainer[i]); }

一个问题可能是如何将字符串值从循环传递到onClick（）函数。由于

，请复制粘贴登录猫输出也和你为什么不能使用列明的得分为每个条目列表视图？ – Aneez

背后有什么想法：'row_Number = new TextView [input1];'？ – donfuxx

@Aneez，我没有使用listvew，因为我需要人们在这里输入信息，并将editview附加到列表视图似乎没有工作，当我最初尝试它 – Daniel

POJO类是一个简单类（可以添加数据槽的制定者或者做一个简单的构造函数）：

private class POJOName { 
    String firstName; 
    String lastName; 

    public String getFirstName() { 
     return firstName; 
    } 

    public void setFirstName(String firstName) { 
     this.firstName = firstName; 
    } 

    public String getLastName() { 
     return lastName; 
    } 

    public void setLastName(String lastName) { 
     this.lastName = lastName; 
    } 
}

这个类可以被用来存储第一名称，也是姓氏然后你用playerDetailsButton[i].setTag(here you put the pojo object);然后

//generate OnClick Listener for button 
    PlayerDetailsButtonOnClick = new View.OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      POJOName pojo = (POJOName)v.getTag(); 
      String fullName = pojo.getFirstName()+" "+pojo.getLastName(); 
      toast(fullName); 

      } 
     };

我也设法解决这个第二种方式。

我为for循环中的int i值分配了一个final int j变量。然后在OnClick（）中，我引用了相关的editview，像这样[class] .this。[viewname] [j] .gettext（）。toString（）; 所以我的代码如下所示：

 final int j = i; 


     playerDetailsButton[i].setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       Log.d("detailsOnClick", "Button Pressed"); 
       inputFName = GroupDetails1.this.fNameInput[j].getText().toString(); 
       Log.d("inputFNameOnClick", inputFName); 

       inputLName = (GroupDetails1.this.lNameInput[j].getText()).toString(); 
       toast(inputFName); 
       toast(inputLName); 
    }

感谢您的帮助和输入
