android - 如何通过解析json数据动态添加table view

Question

我正在将一个函数调用到一个线程中，并将这些对象放入 tableView 但我正在处理非法状态异常。我无法解决为什么？这是我负责调用该函数的代码:

 runOnUiThread(new Runnable() {

                                            fillTable(jArray);

                                    }
                               });

函数是:

private void fillTable(JSONArray jArray){

    TextView t1v = new TextView(ReportAllActivity.this);
    TextView t2v = new TextView(ReportAllActivity.this);
    TextView t3v = new TextView(ReportAllActivity.this);
    TextView t4v = new TextView(ReportAllActivity.this);
    TextView t5v = new TextView(ReportAllActivity.this);
    TextView t6v = new TextView(ReportAllActivity.this);
    ArrayList<JSONObject> listdata = new ArrayList<JSONObject>();     
    for(int i = 0 ; i < jArray.length() ; i++)
    {
        listdata.add(jArray.optJSONObject(i));

    }
    int i = jArray.length()-1;

    while( i >= 0 )
    {
        try {
            json_data = listdata.get(i);
            //json_data = jArray.getJSONObject(i);
            TableRow tbrow = new TableRow(ReportAllActivity.this);
            t1v.setText(json_data.getString("heat"));
            t1v.setTextColor(Color.WHITE);
            t1v.setGravity(Gravity.CENTER);
            tbrow.addView(t1v);

            t2v.setText(json_data.getString("oc_count"));
            t2v.setTextColor(Color.WHITE);
            t2v.setGravity(Gravity.CENTER);
            tbrow.addView(t2v);

            t3v.setText(json_data.getString("who"));
            t3v.setTextColor(Color.WHITE);
            t3v.setGravity(Gravity.CENTER);
            tbrow.addView(t3v);

            t4v.setText(json_data.getString("alarm"));
            t4v.setTextColor(Color.WHITE);
            t4v.setGravity(Gravity.CENTER);
            tbrow.addView(t4v);


            t5v.setText(json_data.getString("do_duration"));
            t5v.setTextColor(Color.WHITE);
            t5v.setGravity(Gravity.CENTER);
            tbrow.addView(t5v);


            t6v.setText(json_data.getString("input_time"));
            t6v.setTextColor(Color.WHITE);
            t6v.setGravity(Gravity.CENTER_HORIZONTAL);
            tbrow.addView(t6v);
            listdata.remove(i);
            i--;
            reportTable.addView(tbrow);
        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }  



    }
}

和我的 LogCat 文件:

我该如何解决这个问题？提前致谢。

您的问题出现是因为到处都使用相同的 TextView。

tbrow.addView(t1v);

您将在每次迭代中添加此 View 。但这应该是不同的看法。您应该在算法的每次迭代中创建不同的 TextView。
