【问题描述】：
我正在开发应用程序，将动态数据添加到多个表视图。结构如下。
我在 onPostExecute 中的代码是：
protected void onPostExecute(List<String> results){
int ind,i = 0;
ScrollView sv=null;
TableLayout tl=null;
TableRow tr = null;
int mjsonlength=results.size();
if(results!=null){
TableLayout indextl=(TableLayout)findViewById(R.id.indextablelayout);
TableRow indextr=new TableRow(SubProducts.this);
//indext1.moveToFirst();
LinearLayout llt=(LinearLayout)findViewById(R.id.alltablell);
//for(int f=0;f<mjsonlength;f++){
for( ind=0;ind<indextitle.size();ind++)
{
TextView indextv=new TextView(SubProducts.this);
indextv.setBackgroundResource(R.drawable.greenbg);
indextv.setHeight(25);
indextv.setWidth(50);
indextv.setId(6);
indextv.setTextColor(Color.WHITE);
indextv.setText(indextitle.get(ind));
indextv.setPadding(20,10,6,3);
indextr.addView(indextv);
indextl.addView(indextr,6);
sv=new ScrollView(SubProducts.this);
tl=new TableLayout(SubProducts.this);
for( i=0;i<mjsonlength;i++){
tr=new TableRow(SubProducts.this);
if(ind==i) {
RelativeLayout rl=new RelativeLayout(SubProducts.this);
Resources res = getResources(); //resource handle
rl.setBackgroundResource(R.drawable.prd_box);
RelativeLayout.LayoutParams newParams1 = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
image=new ImageView(SubProducts.this);
image.setLayoutParams(newParams1);
image.setId(1);
image.setImageBitmap(bmp);
image.setPadding(5, 20, 5, 5);
rl.addView(image,1);
RelativeLayout.LayoutParams lprams = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
lprams.addRule(RelativeLayout.RIGHT_OF, 1);
TextView tv1=new TextView(SubProducts.this);
Spanned marked_up = Html.fromHtml(description.get(i));
tv1.setText((marked_up.toString()).substring(1, 170).replaceAll(" ",""));
tv1.setLayoutParams(lprams);
tv1.setId(2);
tv1.setHeight(150);
tv1.setWidth(130);
tv1.setPadding(20, 10, 0, 10);
rl.addView(tv1,2);
RelativeLayout.LayoutParams newParams = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
newParams.addRule(RelativeLayout.BELOW, 2);
TextView tv=new TextView(SubProducts.this);
tv.setText(productname.get(i));
tv.setLayoutParams(newParams);
tv.setTextColor(Color.WHITE);
tv.setId(3);
tv.setPadding(10, 0, 0, 10);
rl.addView(tv,3);
tr.addView(rl);
tr.setPadding(5, 10, 5, 10);
}
tl.addView(tr);
}
sv.addView(tl);
llt.addView(sv);
}
}
}
我收到如下错误：

两个循环的循环变量值应该相同才能获得相应产品的子产品。我正在与上述错误作斗争。任何有想法的人。请建议我提供适当的解决方案。提前致谢。
编辑：
ArrayList<String> productname=new ArrayList<String>();
ArrayList<String> description=new ArrayList<String>();
ArrayList<String> indextitle=new ArrayList<String>();
ArrayList<String> mStrings = new ArrayList<String>();
在doINBackground下：
JSONObject json = array.getJSONObject(i);
manJson = json.getJSONObject("product");
mStrings.add(manJson.getString("productimage"));
productname.add(manJson.getString("productname"));
indextitle.add(manJson.getString("subcategoryid"));
description.add(manJson.getString("description"));
【问题讨论】：
-
你可以在 for 循环中发布 indextitle 集合的声明和定义
-
Thanq Dinesh。我已经编辑了我的问题，请看一下。
-
你能发布你的json字符串格式吗？
-
thanq Dinesh..data 是：[{"product":{"productimage":"img.jpg","subcategoryid":"prod1","productname":"name","description ":"description"}},{"product":continues.....}}]
