我的应用程序中有一个自定义列表视图。用户的需求因他选择的选项而异，结果显示在列表视图中。我通过 usingArrayList<String>和其他时间代表同一个列表，同时使用 ArrayList<HashMap<String,String>>. 现在，在使用前一个 ieArrayList<String>时，listView 行中的结果会完美对齐，但是在使用后一个 ieArrayList<HashMap<String,String>>时，对齐会变得更糟。我不明白问题可能是什么。请帮忙！
下面我发布了在我的自定义 Listview 中用作一行的 XML 的图像、代码和源代码。

代码：
对于Arraylist<HashMap<String,String>>
ArrayList<HashMap<String,String>> searchList = new ArrayList<HashMap<String,String>>();
for(int i=0;i<productName.size();i++)
{
String currentListItem=productName.get(i).toString();
if(textLength<=currentListItem.length()){
//compare the String in EditText with Names in the ArrayList
if(searchText.equalsIgnoreCase(currentListItem.substring(0,textLength))){
HashMap<String,String> temp = new HashMap<String,String>();
temp.put("PRODUCTNAME",productName.get(i));
temp.put("PRODUCTID", productID.get(i));
temp.put("BRANDNAME", brandName.get(i));
temp.put("VENDORNAME", vendor.get(i));
temp.put("OPENINGSTOCK", openingStock.get(i));
temp.put("AVAILABLESTOCK", availableStock.get(i));
temp.put("ADDSTOCK", addStock.get(i));
temp.put("PURCHASRPRICE", purchasePrice.get(i));
temp.put("SALESPRICE", salesPrice.get(i));
searchList.add(temp);
}
}
}
SimpleAdapter aaadapter = new SimpleAdapter(
new_stock_io.this,
