应用程序读取JSON数据。然后它将它列入清单视图(正确),但在按下一个项目后,我会始终得到相同的值显示。在我认为是问题的代码下方,但找不到一个。android发送intent额外
try{
JSONArray jArray = new JSONArray(result);
for(int ii=0;ii<jArray.length();ii++){
JSONObject json_data = jArray.getJSONObject(ii);
courseName = json_data.getString("fullname");
HashMap<String,String> map = new HashMap<String, String>();
map.put("fullname", courseName);
myCoursesList.add(map);
}
} catch(JSONException e){
Log.e("log_tag", "Error parsing data "+e.toString());
}
ListAdapter adapter = new SimpleAdapter(this, myCoursesList,R.layout.my_courses_layout,
new String[] {"fullname"}, new int[] { R.id.course});
setListAdapter(adapter);
ListView lv = getListView();
lv.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView<?> parent, View view, int position, long id){
String fn = ((TextView)findViewById(R.id.course)).getText().toString();
Intent in = new Intent(getApplicationContext(), courseActivity.class);
in.putExtra("fullname", fn);
startActivity(in);
}
});
感谢它的工作(我会在7分钟内接受答案)也许你可以解释它有什么区别? – LTnewbie 2012-04-15 11:52:03
单击某个项目时,其视图将返回为** onItemClick **中的参数,因此您需要使用该视图执行findViewById以获取选定行的TextView – waqaslam 2012-04-15 11:53:59
