Question

这是我的代码：

    private void InitialContact(final Context context)
{
    final ContactDatabase db = new ContactDatabase(context);
    context.openOrCreateDatabase("****", MODE_PRIVATE, null);
    if(refrech){
        refrech(db, context);
    } 
    getcontact(db, context);
    db.close();
}

getContact fonction（在主线程中）

   private void getcontact(final ContactDatabase db, final Context context){
    SQLiteDatabase dbread = db.getReadableDatabase();
    String[] retour = {
        "pseudo",
        "adresse",
        "image", "ID"
        };
    Cursor cursor = dbread.query("Contact", retour, null, null, null, null, "pseudo");
    while(cursor.moveToNext()) {
        String pseudo = cursor.getString(cursor.getColumnIndexOrThrow("pseudo"));
        Log.d("debug", "getcontact: "+pseudo);
        listcontact.add(new Contact(pseudo));
    }
    cursor.close();
}

Asynchrone任务刷新

private void refrech(final ContactDatabase db, final Context context){
    final SQLiteDatabase dbwrite = db.getWritableDatabase();
    db.onRefresh(dbwrite);
    SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context.getApplicationContext());
    int ID = preferences.getInt("ID", 0);
    if(ID != 0){
        ApiInterface mApiService = this.getInterfaceService();
        Call<ContactCall> mService = mApiService.getcontact(ID);
        mService.enqueue(new Callback<ContactCall>() {
            @Override
            public void onResponse(Call<ContactCall> call, Response<ContactCall> response) {
                ContactCall ContactCallobjet = response.body();
                ArrayList pseudo = ContactCallobjet.isLogin;
                for(int i = 0 ;pseudo.size() <= i; i++){
                    ContentValues values = new ContentValues();
                    String contact = (String) pseudo.get(i);
                    values.put("pseudo", contact);
                    values.put("adresse", "test");
                    values.put("image", "test");
                    values.put("ID", "5");
                    dbwrite.insert("Contact", null, values);
                }
            }

            @Override
            public void onFailure(Call<ContactCall> call, Throwable t) {
                Log.d("DEBUG", "populateWithInitialContacts: "+t.getMessage());
            }
        });
    } else {
        Log.d("DEBUG", "populateWithInitialContacts: Error ID");
    }
}

我的问题是在asynchrone函数（refrech）之前调用getContact函数我测试了一个CallBack但它没有用

在onResponse和失败回调中调用getContact方法：

private void InitialContact(final Context context) {
    final ContactDatabase db = new ContactDatabase(context );
    context.openOrCreateDatabase("****", MODE_PRIVATE, null);
    if(refrech){
        refrech(db, context);
    } else {
        getcontact(db, context);
    }
    db.close();
}

private void refrech(final ContactDatabase db, final Context context){
    final SQLiteDatabase dbwrite = db.getWritableDatabase();
    db.onRefresh(dbwrite);
    SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context.getApplicationContext());
    int ID = preferences.getInt("ID", 0);
    if(ID != 0){
        ApiInterface mApiService = this.getInterfaceService();
        Call<ContactCall> mService = mApiService.getcontact(ID);
        mService.enqueue(new Callback<ContactCall>() {
            @Override
            public void onResponse(Call<ContactCall> call, Response<ContactCall> response) {
                ContactCall ContactCallobjet = response.body();
                ArrayList pseudo = ContactCallobjet.isLogin;
                for(int i = 0 ;pseudo.size() <= i; i++){
                    ContentValues values = new ContentValues();
                    String contact = (String) pseudo.get(i);
                    values.put("pseudo", contact);
                    values.put("adresse", "test");
                    values.put("image", "test");
                    values.put("ID", "5");
                    dbwrite.insert("Contact", null, values);
                    // call get contacts after the response
                    getcontact(db, context);
                }
            }

            @Override
            public void onFailure(Call<ContactCall> call, Throwable t) {
                Log.d("DEBUG", "populateWithInitialContacts: "+t.getMessage());
                // call get contacts on error
                getcontact(db, context);
            }
        });
    } else {
        Log.d("DEBUG", "populateWithInitialContacts: Error ID");
        // call get contacts on error id
        getcontact(db, context);
    }
}

改造asynchrone塔什
