Question

伙计们正在创建一个基于json格式的表

{"Seat Availability":[{"Ship":"Kavaratti","Departure Date":"10/12/2014"},{"Class":"Bunk","Seats":"178"},{"Class":"Bunk","Seats":"200"},{"Class":"Bunk","Seats":"214"},{"Class":"Bunk","Seats":"246"},{"Class":"First","Seats":"0"},{"Class":"Second","Seats":"112"},{"Class":"Second","Seats":"120"},{"Class":"Second","Seats":"95"},{"Class":"Second","Seats":"97"},{"Ship":"Kavaratti","Departure Date":"22/12/2014"},{"Class":"Bunk","Seats":"0"},{"Class":"Bunk","Seats":"1"},{"Class":"First","Seats":"0"},{"Class":"Second","Seats":"10"},{"Class":"Second","Seats":"19"},{"Class":"Second","Seats":"24"},{"Class":"Second","Seats":"6"},{"Ship":"Kavaratti","Departure Date":"03/01/2015"},{"Class":"Bunk","Seats":"229"},{"Class":"Bunk","Seats":"256"},{"Class":"First","Seats":"0"},{"Class":"Second","Seats":"105"},{"Class":"Second","Seats":"109"}]}

除了最后一批船只细节外，一切正常。我无法理解为什么没有显示最后一艘船的细节。

这是我使用的解析代码

        TableLayout ll = (TableLayout) findViewById(R.id.tableLayoutProduct);


        JSONObject json = null;
        try {
            json = new JSONObject(result);
        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }   
        result = "";
        JSONArray arr = null;
        try {
            arr = json.getJSONArray("Seat Availability");
        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        TextView heading = (TextView) findViewById(R.id.heading);
        heading.setText("Seat Availability: "+destination);


        for(int i=0,j=0,z=0; i<arr.length(); i++){      
            TableRow tbrow1 = new TableRow(HttpExample.this);
            TableRow tbrow2 = new TableRow(HttpExample.this);
            TableRow tbrow3 = new TableRow(HttpExample.this);

            tbrow1.setBackgroundColor(Color.parseColor("#C9D1F7"));
            if(i==0){
            TextView tv4 =  new TextView(HttpExample.this);
            tv4.setText(" Ship  ");
            TextView tv5 =  new TextView(HttpExample.this);
            tv5.setText(" Departure Date ");            
            tbrow1.addView(tv4);
            tbrow1.addView(tv5);
            }
            else{
                TextView tv3 =  new TextView(HttpExample.this);
                tv3.setText(" ");
                TextView tv4 =  new TextView(HttpExample.this);
                tv4.setText("  ");

                tbrow1.addView(tv4);

            }

            TextView tv1=new TextView(HttpExample.this);
            TextView departure_date = new TextView(HttpExample.this);   
            TextView tv2 = new TextView(HttpExample.this);

            try {

                while(jo.has("Class"))
                    {
                    tv_heading[z] = new TextView(HttpExample.this);

任何人都可以指出问题

Answer 1

发现问题..它需要在while循环中使用break语句在i ++之后如果（I＆GT = arr.length（））中断;

动态添加最后一行未显示
