从MYSQL PHP Slim翻新回收站视图

Question

我正在尝试学习如何从mySQL加载回收器视图。遵循了一些教程，但是显示了回收站视图，但没有任何内容。所以我不确定我做错了什么。
我想做的是，我有一个应用程序，可以让我拍照并发送一些输入到我的xammp服务器。然后，此应用将使您可以使用回收站视图来查看图片和一些文本字段，最终可以单击它们以获取更多信息。最终，我想将其转变为我提供给当地动物收容所之类的应用程序。他们在一个应用程序上为他们的狗拍照，然后人们可以下载另一个应用程序并查看可用的狗。

现在，我知道图像内容被弄乱了，因此我将其记录下来。我的“ url”是我服务器上的路径，而不是http url，我还没有弄清楚如何使其正常工作，但我知道它不适用于毕加索（我想这样做，我对此有些陌生），仍在学习，这就是为什么有毕加索的东西存在的原因。

TL; DR 但是我无法让recyclerview在页面上显示任何数据，也就是firsname，lastname。

这是我的index.php

$app->get('/getprofilepic', function(request $request, Response $response){

$db = new profilepic; 
$profiledata = $db->getprofilepic();
$response->getBody()>write(json_encode(array("profiledata"=>$profiledata)));
});

这是我的php个人资料

     private $con; 

     function __construct(){

        require_once dirname(__FILE__) . '/DbConnect.php';
        $db = new DbConnect; 
        $this->con = $db->connect(); 
    }

public function getprofilepic(){
        $stmt = $this->con->prepare("SELECT doginfohometab1db.ID, doginfohometab1db.firstnametxt, doginfohometab1db.lastnametxt, profilepicdb.picurl FROM doginfohometab1db LEFT JOIN profilepicdb ON doginfohometab1db.ID = profilepicdb.ID  WHERE doginfohometab1db.ID in(SELECT ID FROM doginfohometab1db WHERE NOT EXISTS (SELECT ID FROM dogdischargeinfohometab1db WHERE doginfohometab1db.id = dogdischargeinfohometab1db.id))");
        $stmt->execute(); 
        $stmt->bind_result($ID, $firstnametxt, $lastnametxt, $picurl);
        $profiledata = array();             
        while($stmt->fetch()){ 
        $temp = array(); 
    $temp ['ID'] = $ID;
    $temp ['firstnametxt'] = $firstnametxt; 
    $temp ['lastnametxt'] = $lastnametxt; 
    $temp ['picurl'] = $picurl;
    array_push($profiledata, $temp);
        }
        return $profiledata; 
    }
}

这是我的邮递员回复

{"profiledata": 

[{“ ID”：“ hvg766khhv”，“ firstnametxt”：“ hvg”，“ lastnametxt”：“ khhv”，“ picurl”：“ C：\ xampp \ htdocs \ pathways1 \ includes / uploads / 1535685930271.jpg “}，{” ID“：” jdjd676jdjf“，” firstnametxt“：” jdjd“，” lastnametxt“：” jdjf“，” picurl“：” C：\ xapp \ htdocs \ pathways1 \ includes / uploads / 1535686965814.jpg“ }]}

这是我的api调用

@GET("getprofilepic")
Call<PtList> PtList();

PtList类

import java.util.ArrayList;

 public class PtList {

@SerializedName("ptList")
private ArrayList<dogdata> ptList;

public ArrayList<dogdata> getdogArrayList(){
    return ptList;
}

public void setdogArrayList(ArrayList<dogdata> dogArrayList){
    this.ptList = dogArrayList;
}
}

这是我的dogdata类

public class dogdata {
@SerializedName("firstnametxt")
private String firstnametxt;
@SerializedName("lastnametxt")
private String lastnametxt;
@SerializedName("ID")
private String ID;

private boolean isSelected = false;
@SerializedName("picurl")
private String picurl;

dogdata(String firstnametxt, String lastnametxt, String ID, String picurl){

    this.ID = ID;
    this.firstnametxt = firstnametxt;
    this.lastnametxt = lastnametxt;
    this.picurl = picurl;
}

public String getID(){
    return ID;
}

public void setID(String ID){
    this.ID = ID;
}

public String getPicurl(){
    return picurl;
}

public void setPicurl (String picurl){
    this.picurl = picurl;
}

public String getFirstnametxt(){
    return firstnametxt;
}

public void setFirstnametxt(String firstnametxt){
    this.firstnametxt = firstnametxt;
}

public String getLastnametxt(){
    return lastnametxt;
}

public void setLastnametxt(String lastnametxt){
    this.lastnametxt = lastnametxt;
}

public void setSelected(boolean selected) {
    isSelected = selected;
}

public boolean isSelected() {
    return isSelected;
}
}

这是我的活动课程

 public class TreatmentMain extends AppCompatActivity implements View.OnClickListener {

private RecyclerView mptRecyclerView;
private RecyclerView.Adapter mptAdapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_treatment_main);

    downdogdata();
}

private void generatePtList(ArrayList<dogdata> ptList){
    mptRecyclerView = (RecyclerView) findViewById(R.id.ptrecycler_view);
    mptAdapter = new TreatmentAdapter(this, ptList);
    RecyclerView.LayoutManager ptmanager = new LinearLayoutManager(TreatmentMain.this);
    mptRecyclerView.setHasFixedSize(true);
    mptRecyclerView.setLayoutManager(ptmanager);
    mptRecyclerView.setAdapter(mptAdapter);
}

public void downdogdata() {

    Call<PtList> call = RetrofitClient.getInstance().getAPIService().PtList();

    call.enqueue(new Callback<PtList>() {
        @Override
        public void onResponse(Call<PtList> call, Response<PtList> response) {

            if (response.code() == 200) {
              generatePtList(response.body().getdogArrayList());
            }
            else if (response.code() == 422)
                Toast.makeText(TreatmentMain.this, "Opps your code don't work bro", Toast.LENGTH_LONG).show();
            {
            } }

        @Override
        public void onFailure(Call<PtList> call, Throwable t) {
            Toast.makeText(TreatmentMain.this, "Opps your code don't work bro on failure toast", Toast.LENGTH_LONG).show();
        }
    });
}

@Override
public void onClick(View view) {
    switch (view.getId()){
        case R.id.txmainback:
            Intent txmainback = new Intent(this, MainActivity.class);
            startActivity(txmainback);
    }
}
}

最后是我的适配器类

 public class TreatmentAdapter extends RecyclerView.Adapter<TreatmentAdapter.MyptViewHolder> {
private ArrayList<dogdata> mptModelList;

private myptAdapterListener mptListener;
String ID;
Context mptcontext;
public interface myptAdapterListener{
    void ontextClick(int position);
}

public TreatmentAdapter(Context context, ArrayList<dogdata> mptModelList) {
    this.mptModelList = mptModelList;
    mptcontext = context;
}

@Override
public MyptViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.treatmentrow, parent, false);
    return new MyptViewHolder(view);
}

@Override
public void onBindViewHolder(final MyptViewHolder holder, final int position) {
    final dogdata ptmodel = mptModelList.get(position);
    holder.Treatmentfirstname.setText(ptmodel.getFirstnametxt());
    holder.Treatmentlastname.setText(ptmodel.getLastnametxt());
 //   Picasso.get().load(ptmodel.getPicurl()).fit().centerCrop().error(R.drawable.ic_launcher_foreground).into(holder.ptreatmentprofile);
    ID = ptmodel.getID();

    holder.view.setBackgroundColor(ptmodel.isSelected() ? Color.CYAN: Color.WHITE);
    holder.view.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            ptmodel.setSelected(!ptmodel.isSelected());
            holder.view.setBackgroundColor(ptmodel.isSelected() ? Color.GREEN : Color.WHITE);
            mptListener.ontextClick(position);
        }
    });
}

@Override
public int getItemCount() {
    return mptModelList == null ? 0 : mptModelList.size();
}

public class MyptViewHolder extends RecyclerView.ViewHolder {

    private View view;
    private TextView Treatmentfirstname;
    private TextView Treatmentlastname;
    private ImageView ptreatmentprofile;

    public MyptViewHolder(final View View) {
        super(View);
        view = View;
       Treatmentfirstname = (TextView) View.findViewById(R.id.Treatmentfirstname);
       Treatmentlastname =(TextView) View.findViewById(R.id.Treatmentlastname);
       ptreatmentprofile = (ImageView) View.findViewById(R.id.ptreatmentprofile);
    }
}
}
