Answer 1

MyDb db=new MyDb(this); 
    db.open(); 
private static final String ClientName= "ClientName"; 
    private static final String projectName= "projectName"; 
ArrayList<HashMap<String, String>> contactList = null; 
       try { 
          JSONObject jsonObj = new JSONObject(yourJsonStringName); 

          // Getting JSON Array node 
          JSONArray contacts = jsonObj.getJSONArray(info); 

          // looping through All Contacts 
          for (int i = 0; i < contacts.length(); i++) { 
           JSONObject c = contacts.getJSONObject(i); 

           // tmp hashmap for single contact 
           HashMap<String, String> contactdata = new HashMap<String, String>(); 

           // adding each child node to HashMap key => value 
           contactdata.put(ClientName, c.getString(ClientName)); 
           contactdata.put(projectName, c.getString(projectName)); 
           // To Insert into Db 
           ContentValues cv=new ContentValues(); 
           cv.put(MyDb.name, c.getString(ClientName).toString()); 
           cv.put(MyDb.address, c.getString(projectName).toString()); 
           db.insertdata(cv); 
           // adding contact to contact list 
           contactList.add(contactdata); 

           //tv=(TextView)findViewById(R.id.tv4); 

          } 
         } catch (JSONException e) { 

         } 

Créer une classe Seprate pour DB

 public class MyDb 
{ 
    Sqldb db; 
    Context context; 
    SQLiteDatabase sdb; 
    public static final String DB="DB.db"; 
    public static final String T_Name="table1"; 
    public static final String name="name"; 
    public static final String address="address"; 
    public static final String Table="create table table1(_id integer primary key,name text,address text)"; 
    // create construtor and call innner class" Sqldb" 
    public MyDb(Context context) 
    { 
     this.context=context; 
     db=new Sqldb(context, DB, null, 1); 
    } 
    public void open() 
    { 
     sdb=db.getWritableDatabase(); 
    } 
    // to insert data in table 
    public void insertdata(ContentValues cv) 
    { 
     sdb.insert(T_Name, null, cv); 
    } 

    //create one inner class and extend it by SQLITEOPENHELPER and then after add constructor and method 
    public class Sqldb extends SQLiteOpenHelper 
    { 

     public Sqldb(Context context, String name, CursorFactory factory, 
       int version) { 
      super(context, name, factory, version); 
      // TODO Auto-generated constructor stub 
     } 

     @Override 
     public void onCreate(SQLiteDatabase db) { 
      // TODO Auto-generated method stub 
      db.execSQL(Table); 
     } 

     @Override 
     public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
      // TODO Auto-generated method stub 

     } 

    } 
}
