我正在创建一个具有不同json文件的可更改json信息的项目，问题是当我点击第一个单选按钮时效果很好但是当我点击第二个时，列表将完美显示但是它是从两个文件中解析出来的。这是我的代码：
public void showFoodItems(String shit)
{
movieList.clear();
adapter.notifyDataSetChanged();
// Creating volley request obj
JsonArrayRequest movieReq = new JsonArrayRequest(
"http://users.abdullahadhaim.com/users/WebServiceResturant.asmx/getFoodItems?categoryName="
+ shit, new Response.Listener<JSONArray>() {
@Override
public void onResponse(JSONArray response) {
Log.d(TAG, response.toString());
// Parsing json
for (int i = 0; i < response.length(); i++) {
try {
JSONObject obj = response.getJSONObject(i);
Movie movie = new Movie();
movie.setTitle(obj.getString("title"));
movie.setThumbnailUrl(obj.getString("image"));
movie.setPrice(((Number) obj.get("price"))
.doubleValue());
movie.setOrderNum(obj.getInt("categoryno"));
movie.setCategory(obj.getString("category"));
// adding movie to movies array
movieList.add(movie);
} catch (JSONException e) {
e.printStackTrace();
}
}
// notifying list adapter about data changes
// so that it renders the list view with updated data
adapter.notifyDataSetChanged();
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
}
});
// Adding request to request queue
AppController.getInstance().addToRequestQueue(movieReq);
/* @#@#@#@# JSON Items ListView END @#@#@#@# */
}
这就是radioButton onCLick的方法：
rd1.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// TODO Auto-generated method stub
/// movieList.clear();
// adapter.notifyDataSetChanged();
// listView.setAdapter(adapter);
showFoodItems("Starter");
}
});
rd2.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// TODO Auto-generated method stub
// movieList.clear();
// //adapter.notifyDataSetChanged();
//listView.setAdapter(adapter);
showFoodItems("Desserts");
}
});
