web services - IllegalStateException in Android TableLayout

Question

I wrote a code to create table layout and table rows dynamically and add the values form web service. It is giving me TargetInvocation exception. What could be the reason for this?

protected void onPostExecute(final ArrayList<DeleteuserDetails>deleteuserDetails) {

        for(int i=0;i<=deleteuserDetails.size();i++){

                TableRow deleteUserRow=new TableRow(Deleteuser.this);
                deleteUserRow.setId(i);
                deleteUserRow.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
                CheckBox select_id = new CheckBox(Deleteuser.this);
                select_id.setId(i);
                deleteUserRow.addView(select_id);
                deleteuserList[i]=new TextView(Deleteuser.this);
                deleteuserList[i].setId(i);
                deleteuserList[i].setText(deleteuserDetails.get(i).getUserId());
                deleteUserRow.addView(deleteuserList[i]);
                uName=new TextView(Deleteuser.this);
                uName.setId(i);
                uName.setText(deleteuserDetails.get(i).getUserName());
                deleteUserRow.addView(uName);
                Userrole=new TextView(Deleteuser.this);
                Userrole.setId(i);
                Userrole.setText(deleteuserDetails.get(i).getUserRole());
                deleteUserRow.addView(Userrole);
                CreatedDate=new TextView(Deleteuser.this);
                CreatedDate.setId(i);
                CreatedDate.setText(deleteuserDetails.get(i).getCreatedDate());
                deleteUserRow.addView(CreatedDate);
                CreatedBy=new TextView(Deleteuser.this);
                CreatedBy.setId(i);
                CreatedBy.setText(deleteuserDetails.get(i).getCreatedBy());
                deleteUserRow.addView(CreatedBy);
                userdetailTable.addView(deleteUserRow,new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
                select_id.setTag(i);
                select_id.setOnClickListener(listener);
            }
        TableRow deleteUserRow1=new TableRow(Deleteuser.this);
        deleteUserRow1.setId(100);
        deleteUserRow1.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
        Button btn_user_delete=new Button(Deleteuser.this);
        btn_user_delete.setText("Delete");
        deleteUserRow1.addView(btn_user_delete);
        btn_user_delete.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                new DeleteUserid().execute(checkedValue);
            }
        });


    }

IllegalStateException rises at the line

   userdetailTable.addView(deleteUserRow,new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));

Answer 1

Are you initializing the Array deleteuserList in you code....

You need to call the following line before the for loop...

deleteuserList = new TextView[deleteuserDetails.size()];
