这里我需要从服务器json响应中将值保存到sqlite中，但到目前为止我还不知道如何执行此操作： 这是我的数据库：
import android.content.ContentValues;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
import java.util.ArrayList;
import java.util.List;
public class Account_SF_DB extends SQLiteOpenHelper {
private static final int DATABASE_VERSION = 4;
private static final String DATABASE_NAME = "account.db";
public Account_SF_DB(android.content.Context context ) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db) {
String CREATE_TABLE_ACCOUNT= "CREATE TABLE " + Model_Account.Accunt_Table + "("
+ Model_Account.id + " INTEGER PRIMARY KEY AUTOINCREMENT ,"
+ Model_Account.company_groups + " TEXT, "
+ Model_Account.Parent_company + " TEXT, "
+ Model_Account.Company_name + " TEXT, "
+ Model_Account.Company_type + " TEXT ,"
+ Model_Account.Address_line1 + " TEXT ,"
+ Model_Account.Address_line2 +" TEXT ,"
+ Model_Account.Address_line3 + " TEXT ,"
+ Model_Account.State + " TEXT ,"
+ Model_Account.State_id + " INTEGER ,"
+Model_Account.City + " TEXT ,"
+Model_Account.CityID + " INTEGER ,"
+Model_Account.Pincode + " TEXT ,"
+Model_Account.Landline1 + " TEXT ,"
+Model_Account.Landline2 + " TEXT ,"
+Model_Account.Url + " TEXT ,"
+Model_Account.Email_id +" TEXT ,"
+Model_Account.Industry + " TEXT ,"
+Model_Account.IndustryID + " INTEGER ,"
+Model_Account.Account_manager+ " TEXT ,"
+Model_Account.Account_managerid+ " INTEGER ,"
+Model_Account.Region + " TEXT ,"
+Model_Account.regionid + " INTEGER , "
+Model_Account.Muti_location +" TEXT ,"
+Model_Account.mutilocationid+ " INTEGER"
+");";
db.execSQL(CREATE_TABLE_ACCOUNT);
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS " + Model_Account.Accunt_Table);
onCreate(db);
}
public void onInsert(Model_Account accountobj){
SQLiteDatabase db=this.getWritableDatabase();
ContentValues contentobj=new ContentValues();
contentobj.put(Model_Account.company_groups,accountobj.getCompany_group());
contentobj.put(Model_Account.Parent_company,accountobj.getParent_company());
contentobj.put(Model_Account.Company_name,accountobj.getCompany_name());
contentobj.put(Model_Account.Company_type,accountobj.getCompany_type());
contentobj.put(Model_Account.Address_line1,accountobj.getAddrss_line1());
contentobj.put(Model_Account.Address_line2,accountobj.getAddrss_line2());
contentobj.put(Model_Account.Address_line3,accountobj.getAddrss_line3());
contentobj.put(Model_Account.State,accountobj.getState());
contentobj.put(Model_Account.State_id,accountobj.getStateid());
contentobj.put(Model_Account.City,accountobj.getCity());
contentobj.put(Model_Account.CityID,accountobj.getCityid());
contentobj.put(Model_Account.Pincode,accountobj.getPincode());
contentobj.put(Model_Account.Landline1,accountobj.getLandline1());
contentobj.put(Model_Account.Landline2,accountobj.getLandline2());
contentobj.put(Model_Account.Url,accountobj.getUrl());
contentobj.put(Model_Account.Email_id,accountobj.getEmailid());
contentobj.put(Model_Account.Industry,accountobj.getIndusty());
contentobj.put(Model_Account.IndustryID,accountobj.getIndustry_id());
contentobj.put(Model_Account.Account_manager,accountobj.getAccount_manager());
contentobj.put(Model_Account.Account_managerid,accountobj.getAcm_id());
contentobj.put(Model_Account.Region,accountobj.getRegion());
contentobj.put(Model_Account.regionid,accountobj.getRegion_id());
contentobj.put(Model_Account.Muti_location,accountobj.getMulti_location());
contentobj.put(Model_Account.mutilocationid,accountobj.getMutilocation_id());
db.insert(Model_Account.Accunt_Table,null,contentobj);
db.close();
} public int getTaskCount() {
int count=0;
String countQuery = "SELECT * FROM " + Model_Account.Accunt_Table;
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.rawQuery(countQuery, null);
if(cursor != null && !cursor.isClosed()){
count = cursor.getCount();
cursor.close();
}
return count;
}
public List<Model_Account> list(){
String countQuery = "SELECT * FROM " + Model_Account.Accunt_Table;
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.rawQuery(countQuery, null);
List<Model_Account>listobj=new ArrayList<Model_Account>();
if (cursor.moveToFirst()) {
do {
Model_Account modelobj=new Model_Account();
modelobj.setCompany_group(cursor.getString(cursor.getColumnIndex(Model_Account.company_groups)));
modelobj.setState(cursor.getString(cursor.getColumnIndex(Model_Account.State)));
listobj.add(modelobj);
}while (cursor.moveToNext());
}
return listobj;
}
public void stateInsert(Model_Account modelobj){
SQLiteDatabase db=this.getWritableDatabase();
ContentValues contentobj=new ContentValues();
contentobj.put(Model_Account.State,modelobj.getName());
db.insert(Model_Account.Accunt_Table, null, contentobj);
db.close();
}
public List<Model_Account>spinner_state(){
String countQuery = " SELECT * FROM " + Model_Account.Accunt_Table;
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.rawQuery(countQuery, null);
List<Model_Account>listobj=new ArrayList<Model_Account>();
if (cursor.moveToFirst()) {
do {
Model_Account modelobj=new Model_Account();
modelobj.setState(cursor.getString(cursor.getColumnIndex(Model_Account.State)));
listobj.add(modelobj);
}while (cursor.moveToNext());
}
return listobj;
}
}
这是我需要保存值的地方：
String Url = "http://xx.x.x.xx/xx/AcoountCreatePageLoad.svc/Account/AccountPageLoad";
JsonObjectRequest jsonObjRequest = new JsonObjectRequest(Request.Method.GET, Url, new JSONObject(),
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
String server_response = response.toString();
try {
JSONObject json_object = new JSONObject(server_response);
JSONArray json_array = new JSONArray(json_object.getString("AccountPageLoadResult"));
for (int i = 0; i < json_array.length(); i++) {
Model_Account model_spinner = new Model_Account();
JSONObject json_arrayJSONObject = json_array.getJSONObject(i);
model_spinner.setName(json_arrayJSONObject.getString("Name"));
model_spinner.setStateid(json_arrayJSONObject.getInt("PairLinkID"));
account_sf_db.stateInsert(model_spinner);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getBaseContext(), error.toString(), Toast.LENGTH_SHORT).show();
}
});
//Creating request queue
queue.add(jsonObjRequest);
List<Model_Account> yogan=account_sf_db.spinner_state();
final ArrayAdapter<Model_Account> spinnerAdapter = new ArrayAdapter<Model_Account>(this, android.R.layout.simple_dropdown_item_1line, yogan);
spinner_state.setAdapter(spinnerAdapter);
但是它获取空值我需要将它保存在单独的表中或同一个表中
答案 0 :(得分：0)
试试这个
