Android:用于处理多个 ArayStringLists 的自定义适配器 [英] Android: custom adapter for handling more than one ArayStringLists

问题描述

我有一个 Row 布局，有两个 textView，比如说 textViewX 和 textViewY.我知道如何使用适配器用一个 arrayList 填充一个 textView.

I have a Row layout, with two textViews, lets say textViewX and textViewY. I know how to populate one textView with one arrayList using the Adapter.

如何制作自定义适配器来处理两个数组字符串列表以填充包含两个 textView 的 row_layout ?

How do I make a custom Adapter to handle two Array String Lists to populate a row_layout containing two textViews ?

我尝试这样做:

            // Getting the Text view from the ROW_Layout for Year and adding the text from array string lists 
            TextView yearTextView = (TextView) findViewById(R.id.editTextYear);
            try {
                yearTextView.setText((CharSequence) yearStringList);
            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            yearTextView.setTextColor(0xff444444);  // Setting Dark Grey color to text

            // Getting the Text view from the ROW_Layout for Country and adding the text from array string lists
            TextView countryTextView = (TextView) findViewById(R.id.editTextCountry);
            try {
                countryTextView.setText((CharSequence) countryStringList);
            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

应用程序崩溃了，我检查了日志，有一个致命错误"指向这个:

The application crashes, and I checked the logs, and there is a "FATAL ERROR" pointing towards this:

yearTextView.setText((CharSequence) yearStringList);

推荐答案

使用模型类

class Model
{
String value1;
String value2
public void setValue1(String value1)
{
this.value1=value1;
}
public void setValue2(String value2)
{
this.value2=value2;
}
public String getValue1()
{
return this.value1;
}
public String getValue2()
{
return this.value2;
}
}

现在在活动中

 ArrayList<Model> aa = new ArrayList<Model>();

现在使用 for 循环填充列表.下面只是一个例子.只需确保填写列表即可.

Now populate the list say using for loop. Below is just an example. Just make sure you populate the list.

 for(int i=0;i<10;i++)
 {
 Model model = new Model();
 model.setValue1("value1");
 model.setValue2("value2");
 aa.add(model);
 } 

将列表 aa 传递给 CustomAdapter 并在那里使用它

Pass list aa to CustomAdapter and use it there

在获取视图中

 Model mo = (Model) aa.get(position);
 tv1.setText(mo.getValue1());
 tv2.setText(mo.getValue2());
