ArrayAdapter无指的XML [英] ArrayAdapter without refering to xml
本文介绍了ArrayAdapter无指的XML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
我的工作列表视图与节头，现在我有一个这样的ArrayAdapter：
I am working on List View with section headers, now i have a ArrayAdapter like this:
header = new ArrayAdapter<String>(context, R.layout.header);
和我使用这种方式头：
view = header.getView(sectionnum, convertView, parent);
if (view != null) {
TextView headerTitle = (TextView) view.findViewById(R.id.header_title);
}
现在我不想使用 R.layout.header XML，而不是我有一个编程创建的布局，我需要使用，如何使用XML的，而不是？
Now i dont want to use the R.layout.header xml, instead i have a programatically created layout which i need to use, how to use that instead of xml?
推荐答案
这是该地区的答案，但我可以弄清楚如何将它张贴作为评论的那些人的意见在这里。
This is the area to answers, but I could figure out how to post it as a comment to those others comments up here.
所以，我得到这个同样的问题。我认为，这是因为如果这个ID就是我没有，因为我想要动态地使用所有。
So, I'm getting this same problem. I think that is because if this ID's that I don't have because I'm trying to use all dynamically.
我已经试过打电话给我的构造函数把
I already tried call my constructor putting (context, 0, list-of-Objects)
任何其他的解决方案来试试呢？
Any other solution to try?

修改1：所以，这是我的code：
package com.example.frame.graphics;
import java.util.List;
import android.app.Activity;
import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.RelativeLayout;
import android.widget.RelativeLayout.LayoutParams;
import android.widget.TextView;
public class ContextArrayAdapter extends ArrayAdapter<contextitem> {
Activity context;
// int layoutResourceId;
List<contextitem> objects;
public ContextArrayAdapter(Context context, int textViewResourceId,
List<contextitem> objects) {
super(context, textViewResourceId, objects);
// TODO Auto-generated constructor stub
this.context = (Activity) context;
// this.layoutResourceId = textViewResourceId;
this.objects = objects;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
RelativeLayout row = (RelativeLayout) convertView;
ContextHolder holder = null;
if (row == null) {
holder = new ContextHolder();
holder.name = new TextView(context);
holder.counter = new TextView(context);
RelativeLayout.LayoutParams paramsName = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
paramsName.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
RelativeLayout.LayoutParams paramsCount = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
paramsName.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
row = new RelativeLayout(context);
row.addView(holder.name, paramsName);
row.addView(holder.counter, paramsCount);
row.setTag(holder);
parent.addView(row, position);
} else {
holder = (ContextHolder) row.getTag();
}
contextitem contextItem = objects.get(position);
holder.name.setText(contextItem.getName());
int count = contextItem.getCount();
if (count > -1) {
holder.counter.setText(contextItem.getCount());
} else {
holder.counter.setText("");
}
return row;
}
static class ContextHolder {
TextView name;
TextView counter;
}
}
修改2：解决方案（最后） 问题是，我们需要一个线性布局存在。无论是使用XML与否。
Edit 2: Solution (Finally) The thing is that we need that linear layout there. whether using XML or not.
