我正在动态生成表格行以填充来自我的 Android 版本的 json 数据：4.2
这是我的代码：
try {
//HttpResponse response = httpClient.execute(httpGet, localContext);
HttpResponse response = httpClient.execute(httpGet, localContext);
HttpEntity entity = response.getEntity();
text = getASCIIContentFromEntity(entity);
//InputStream input = new BufferedInputStream( response.getEntity().getContent() );
JSONArray ja = new JSONArray(text) ;
// ITERATE THROUGH AND RETRIEVE CLUB FIELDS
int n = ja.length();
for (int i = 0; i < n; i++) {
// GET INDIVIDUAL JSON OBJECT FROM JSON ARRAY
JSONObject jo = ja.getJSONObject(i);
title= jo.getString("Title");
url= jo.getString("URL");
desc.add(jo.getString("Description"));
}
} catch (Exception e) {
e.getLocalizedMessage();
}
return desc;
}
protected void onPostExecute(ArrayList<String> desc) {
int count=0;
TableLayout tl;
TableRow tr;
tl=(TableLayout)findViewById(R.id.tableLayout1);
if (desc!=null) {
for (int current = 0; current < desc.size(); current++) {
tr = new TableRow(VideoCategory.this);
TextView tv2 = (TextView)findViewById(R.id.vtext2);
tv2.setText(desc.get(count));
tr.addView(tv2);
tl.addView(tr, new TableLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
}
}
}
输出： 它说：
没想到应用程序已停止
