很簡單的問題，我想？我如何創建JSON文件並插入（附加）我從Volley請求的新數據（GET）。因此，回顧一下，創建文件並將其附加到我的GET響應中。謝謝！如何創建JSON文件並用排除新數據填充
// Formulate the request and handle the response.
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, url, (String)null,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
Toast.makeText(getActivity(), response.toString() , Toast.LENGTH_LONG).show();
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getActivity(), "Error Fetching Data", Toast.LENGTH_LONG).show();
}
});
mRequestQueue.add(jsonObjectRequest);
我如何讀取文件時存在在用戶的手機上（漂亮不重要，但仍然給人上下文）
public String loadJSONFromAsset() {
String json = null;
try {
InputStream is = getActivity().getAssets().open("test12.json");
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
json = new String(buffer, "UTF-8");
} catch (IOException ex) {
Toast.makeText(getActivity(), "Error Fetching Data", Toast.LENGTH_LONG).show();
return null;
}
return json;
}
謝謝！
