Question

我将创建yii2分页并且我有以下代码，但是它给出了一个错误，比如调用非对象上的成员函数offset（）

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.RatingBar;

import com.github.gcacace.signaturepad.views.SignaturePad;
import com.oviyum.fleetfoot.R;

/**
 * A simple {@link Fragment} subclass.
 */
public class SignatureFragment extends Fragment implements View.OnClickListener {
    private Activity activity;
    private Context context;

    private View view;

    private SignaturePad signaturePad;
    private Button uploadSignature;
    private Button resendOTP;
    private Button submit;

    private RatingBar ratingBar;

    public SignatureFragment() {
        // Required empty public constructor
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        view = inflater.inflate(R.layout.fragment_signature, container, false);
        init();
        return view;
    }

    private void init() {
        signaturePad = (SignaturePad) view.findViewById(R.id.handover_signature_signature_pad);

        uploadSignature = (Button) view.findViewById(R.id.handover_signature_upload_signature);
        uploadSignature.setOnClickListener(this);

        resendOTP = (Button) view.findViewById(R.id.handover_signature_resend_otp);
        resendOTP.setOnClickListener(this);

        ratingBar = (RatingBar) view.findViewById(R.id.handover_signature_experience);

        submit = (Button) view.findViewById(R.id.handover_signature_submit);
        submit.setOnClickListener(this);

    }

    @Override
    public void onAttach(Context context) {
        super.onAttach(context);
        this.context = context;
        this.activity = getActivity();
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.handover_signature_upload_signature:
                break;
            case R.id.handover_signature_resend_otp:
                break;
            case R.id.handover_signature_submit:
                break;
        }
    }
}

通常由gii创建并基于ModelSearch模式的模型通常是分页已经可以通过defualt完成所有必需的参数

最终你可以更改页面大小或配置其他参数

 public function actionIndex() {
        $searchModel = new UsermasterSearch();
        $dataProvider = $searchModel->search(Yii::$app->request->queryParams);
        $dataProvider->query->andWhere( 'user_id  1']);

      // eventually you can change the page sise 
      $dataProvider->pagination->pageSize=5;

        return $this->render('index', ['searchModel' => $searchModel,'dataProvider' => $dataProvider,]);
    }

在你的代码中有两个$ dataProvider的定义（我不知道第二个是否是一个有效的数据提供者）你可以避免这只是改变查询属性，例如：添加和到$ dataProvider

yii2分页剂量不起作用调用非对象上的成员函数offset（）
