ListView 僅顯示 1 個數據，而列表視圖適配器中有 3 個記錄

Question

我想要一個 tabhost 中的列表視圖。 我的數據來自數據庫。 通過改造，我從數據庫中獲得了 3 條記錄。 我將這 3 條記錄傳遞給我創建的 ListView Adapter。 這些記錄一直到 Adapter 的構造函數，但之后在 getView 方法中只有 1 條記錄被訪問 3 次。 我不確定為什么會這樣。

這是我的帖子活動：

public  static final ArrayList<WorkProfilePojo> mProfiles = new ArrayList<>();
BaseURL baseURL = new BaseURL();
VendorPostAdapter pAdapter;
ListView mPostList;
public List<WorkProfilePojo> returnedList = new ArrayList<>();

String lv_vendorId = null;
public static String lv_name;

@Override
protected void onCreate(Bundle savedInstanceState) {

    Intent intent = getIntent();
    lv_vendorId = intent.getStringExtra("lv_vendorId");
    Log.e("vendor id", lv_vendorId);
    lv_name = intent.getStringExtra("lv_name");


    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_post);

    getRetrofit();

}

private void getRetrofit() {
    Retrofit retrofit = new RetrofitObject().getRetrofit();

    final WorkProfileforPostTabAPI mProfileAPI = 
retrofit.create(WorkProfileforPostTabAPI.class);
    final Call<ArrayList<WorkProfilePojo>> mCall = 
mProfileAPI.getWork(lv_vendorId);
    mCall.enqueue(new Callback<ArrayList<WorkProfilePojo>>() {
        @Override
        public void onResponse(Call<ArrayList<WorkProfilePojo>> call, 
Response<ArrayList<WorkProfilePojo>> response) {
            mProfiles.clear();
            returnedList = (ArrayList<WorkProfilePojo>)response.body();
            WorkProfilePojo wp;
            Log.e("Teste2", 
returnedList.get(0).getLv_eventSubCategory());
            for (int i = 0; i<= returnedList.size()-1; i++){
                wp=new WorkProfilePojo();


wp.setLv_vendorWorkId(returnedList.get(i).getLv_vendorWorkId());

wp.setLv_eventSubCategory(returnedList.get(i).getLv_eventSubCategory());

wp.setLv_workDescription(returnedList.get(i).getLv_workDescription());

wp.setLv_numWorkLikes(returnedList.get(i).getLv_numWorkLikes());

wp.setLv_numWorkComments(returnedList.get(i).getLv_numWorkComments());

                mProfiles.add(wp);
            Log.e("retrofit profile size: ", 
String.valueOf(mProfiles.size()));
            populateListView(mProfiles);
        }

        @Override
        public void onFailure(Call<ArrayList<WorkProfilePojo>> call, 
Throwable t) {
            Log.e(TAG, "FAIL");
        }

    });
}

private void populateListView(ArrayList<WorkProfilePojo> mProfiles) {
    mPostList               = (ListView) findViewById(R.id.listVPost);

    Log.e("func prof size: ", String.valueOf(mProfiles.size()));
    pAdapter = new VendorPostAdapter(this, mProfiles, lv_name);

    mPostList.setAdapter(pAdapter);

}

這是我的適配器：

public class VendorPostAdapter extends BaseAdapter {

Context context;
ArrayList<WorkProfilePojo> lv_profiles = new ArrayList<>();
String lv_name;
LayoutInflater inflater;

public VendorPostAdapter(Context context, ArrayList<WorkProfilePojo> 
lv_profiles, String lv_name){
    this.context = context;
    this.lv_profiles =lv_profiles;
    this.lv_name = lv_name;
    Log.e("adapter name", lv_name );
    Log.e("adapter workid", lv_profiles.get(0).getLv_vendorWorkId());
    Log.e("adapter workid", lv_profiles.get(1).getLv_vendorWorkId());
    Log.e("adapter workid", lv_profiles.get(2).getLv_vendorWorkId());
}

private class ViewHolder {

        convertView.setTag(holder);

    }
    else {
        holder = (ViewHolder) convertView.getTag();
    }

    final WorkProfilePojo wp = lv_profiles.get(position);

    Log.e("getView name", lv_name );
    Log.e("getView workid", 
lv_profiles.get(position).getLv_vendorWorkId());
    holder.mtxtViewPartnerName.setText( lv_name );
    holder.mtxtViewEventCategory.setText( wp.getLv_eventSubCategory() );

    FormatDate lv_date = new FormatDate();
holder.mtxtViewDate.setText(lv_date.formatDayMonDateYr(wp.getLv_creationDate()));
    holder.mtxtViewFillDescription.setText(wp.getLv_workDescription());
    holder.mtxtViewFillDescription.setText(wp.getLv_workDescription());

    holder.mimgLikeThumb.setOnClickListener(new View.OnClickListener() {
        @Override
         public void onClick(View v) {
            Intent intent = new Intent(context,

            intent.putExtra("lv_workId", wp.getLv_vendorWorkId());

這是我的 activity_post.xml 包裹在相對布局中

<RelativeLayout

android:layout_height="match_parent"

From retrofit results, I am getting 3 records from database:
func workid:: W00000000000013
func workid:: W00000000000014
func workid:: W00000000000015

But in getView() method I am getting only 1 record coming 3 times:
Likesad name: W00000000000013
Likesad name: W00000000000013
Likesad name: W00000000000013

Answer 1

holder.mtxtViewDate.setText(lv_date.formatDayMonDateYr(wp.getLv_creationDate(getPostion()))); 
holder.mtxtViewFillDescription.setText(wp.getLv_workDescription(getPostion()));
holder.mtxtViewFillDescription.setText(wp.getLv_workDescription(getPostion()));

這可能有效。
