问题描述
我有一个排的布局,有两个textViews,可以说textViewX和textViewY。
我知道如何填充一个TextView的使用适配器1的ArrayList。
我如何自定义适配器处理两个字符串数组列表填充包含两个textViews一个row_layout?
我试着这样做:
//充分利用ROW_Layout年为文本视图,并添加来自字符串数组列表中的文本
TextView的yearTextView =(的TextView)findViewById(R.id.editTextYear);
尝试{
yearTextView.setText((CharSequence的)yearStringList);
}赶上(例外五){
// TODO自动生成catch块
e.printStackTrace();
}
yearTextView.setTextColor(0xff444444); //设置深灰色的颜色为文本 //充分利用ROW_Layout为国家文本视图,并添加来自字符串数组列表中的文本
TextView的countryTextView =(的TextView)findViewById(R.id.editTextCountry);
尝试{
countryTextView.setText((CharSequence的)countryStringList);
}赶上(例外五){
// TODO自动生成catch块
e.printStackTrace();
}
应用程序崩溃,并且我查了日志,并有一个致命错误朝着这个指点:
yearTextView.setText((CharSequence的)yearStringList);
使用一个模型类
类模型
{
字符串值1;
字符串值2
公共无效setValue1(字符串值1)
{
this.value1 =值;
}
公共无效setValue2(字符串值2)
{
this.value2 =值2;
}
公共字符串getValue1()
{
返回this.value1;
}
公共字符串getValue2()
{
返回this.value2;
}
}
现在在活动
的ArrayList<模型与GT; AA =新的ArrayList<模型与GT;();
现在填充使用循环列表说。下面仅仅是一个例子。只要确保你填充列表。
的for(int i = 0;我小于10;我++)
{
型号型号=新模式();
model.setValue1(值1);
model.setValue2(值2);
aa.add(模型);
}
通列表 AA
来CustomAdapter,并用它还有
在getView
名模莫=(模型)aa.get(位置);
tv1.setText(mo.getValue1());
tv2.setText(mo.getValue2());
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.
How do I make a custom Adapter to handle two Array String Lists to populate a row_layout containing two textViews ?
I tried doing this :
// 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();
}
The application crashes, and I checked the logs, and there is a "FATAL ERROR" pointing towards this:
yearTextView.setText((CharSequence) yearStringList);
Use a Model Class
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;
}
}
Now in Activity
ArrayList<Model> aa = new ArrayList<Model>();
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);
}
Pass list aa
to CustomAdapter and use it there
In getView
Model mo = (Model) aa.get(position);
tv1.setText(mo.getValue1());
tv2.setText(mo.getValue2());
