    MyApplication myOpt = (MyApplication)getActivity().getApplicationContext();
    protected Void doInBackground(Void... params) {
        json_data = new ArrayList<Json_Data>();

        try {
            jsonarray = jsonobject.getJSONArray("data");
            for (int i = 0; i < jsonarray.length(); i++) {
                jsonobject = jsonarray.getJSONObject(i);

像这样的chenge xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<Spinner
    android:id="@+id/operator_spinner"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_marginLeft="40dp"
    android:layout_marginRight="40dp"
    android:layout_marginTop="7dp"
    android:gravity="left"
    android:textAlignment="center" >
</Spinner>

<RadioGroup
    android:id="@+id/radioGroup"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="10dp"
    android:orientation="horizontal"
    android:paddingLeft="38dp"
    android:visibility="gone" >

    <RadioButton
        android:id="@+id/_TopUp"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="TopUp " />

    <RadioButton
        android:id="@+id/Special"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Special(2G,3G,SMS,VOICE )" />
