我开发应用程序以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 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

for( ind=0;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

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);

}

}

}

我得到的错误如下：

循环变量值对于两个循环都应该相同Inorder获取相应产品的子产品.我正在与上述错误作斗争.任何有想法的人.Plz建议我适当的解决方案.谢谢提前.

编辑：

ArrayList productname=new ArrayList();

ArrayList description=new ArrayList();

ArrayList indextitle=new ArrayList();

ArrayList mStrings = new ArrayList();

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"));
