为什么我的listview仅显示第一个项目？

Question

这是我的适配器类...别的东西，你应该知道的是，我有一个onItemClickListener并且它不工作，要么 我所做的几乎一切，没有什么在我脑海

import android.content.Context; 
import android.database.DataSetObserver; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.BaseAdapter; 
import android.widget.ImageView; 
import android.widget.ListAdapter; 
import android.widget.TextView; 

import com.example.milad.androidproject4.R; 
import com.example.milad.androidproject4.model.jenresTO; 

import java.util.ArrayList; 


public class listAdapter extends BaseAdapter { 

Context context; 
ArrayList<jenresTO> jenresTOArrayList; 

LayoutInflater inflater; 


public listAdapter(Context context, ArrayList<jenresTO> jenresTOArrayList) { 
    this.context = context; 
    this.jenresTOArrayList = jenresTOArrayList; 
    inflater = LayoutInflater.from(context); 
} 


@Override 
public boolean areAllItemsEnabled() { 
    return false; 
} 

@Override 
public boolean isEnabled(int i) { 
    return false; 
} 

@Override 
public void registerDataSetObserver(DataSetObserver dataSetObserver) { 

} 

@Override 
public void unregisterDataSetObserver(DataSetObserver dataSetObserver) { 

} 

@Override 
public int getCount() { 
    return jenresTOArrayList.size(); 
} 

@Override 
public Object getItem(int position) { 
    return position; 
} 

@Override 
public long getItemId(int position) { 
    return position; 
} 

@Override 
public boolean hasStableIds() { 
    return false; 
} 

@Override 
public View getView(int position, View convertView, ViewGroup viewGroup) { 

    final ViewHolder holder; 

    if (convertView == null) { 
     holder = new ViewHolder(); 
     convertView = inflater.inflate(R.layout.itemelistemoon, null); 
     holder.esmejenre = (TextView) convertView.findViewById(R.id.txtitem); 
     holder.aksejenre = (ImageView) convertView.findViewById(R.id.imgitem); 
     convertView.setTag(holder); 
    } else { 
     holder = (ViewHolder) convertView.getTag(); 
    } 
    holder.aksejenre.setImageResource(jenresTOArrayList.get(position).getPics()); 
    holder.esmejenre.setText(jenresTOArrayList.get(position).getJenres()); 
    return convertView; 
} 

private class ViewHolder { 
    TextView esmejenre; 
    ImageView aksejenre; 
} 

@Override 
public int getItemViewType(int i) { 
    return 0; 
} 

@Override 
public int getViewTypeCount() { 
    return 1; 
} 

@Override 
public boolean isEmpty() { 
    return false; 
} 

}

这里是我的活动类

import android.app.Activity; 
import android.content.Intent; 
import android.database.DataSetObserver; 
import android.os.Bundle; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.AdapterView; 
import android.widget.ArrayAdapter; 
import android.widget.ListAdapter; 
import android.widget.ListView; 

import com.example.milad.androidproject4.R; 
import com.example.milad.androidproject4.model.jenresTO; 
import com.example.milad.androidproject4.page.pagerActivity; 

import java.util.ArrayList; 


public class listActivity extends Activity { 
ArrayList<jenresTO> jenresArraylist = new ArrayList<>(); 
ListView list1; 

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


    jenresTO jenres = new jenresTO(); 
    jenres.setJenres("pop"); 
    jenres.setPics(R.drawable.miladi); 


    jenresTO jenres2 = new jenresTO(); 
    jenres.setJenres("rock"); 
    jenres.setPics(R.drawable.miladi); 


    jenresTO jenres3 = new jenresTO(); 
    jenres.setJenres("rap"); 
    jenres.setPics(R.drawable.miladi); 


    jenresTO jenres4 = new jenresTO(); 
    jenres.setJenres("metal"); 
    jenres.setPics(R.drawable.miladi); 


    jenresTO jenres5 = new jenresTO(); 
    jenres.setJenres("jazz"); 
    jenres.setPics(R.drawable.miladi); 


    jenresArraylist.add(jenres); 
    jenresArraylist.add(jenres2); 
    jenresArraylist.add(jenres3); 
    jenresArraylist.add(jenres4); 
    jenresArraylist.add(jenres5); 


    list1 = (ListView) findViewById(R.id.list1); 

    listAdapter adapter = new listAdapter(this, jenresArraylist); 

    list1.setAdapter(adapter); 

    list1.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) { 
      startActivity(new Intent(listActivity.this, pagerActivity.class) 
        .putExtra("listjenres", jenresArraylist) 
        .putExtra("position", position)); 

     } 


    }); 


} 

}

，这是XML

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:orientation="vertical" android:layout_width="match_parent" 
android:layout_height="match_parent"> 


<ListView 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:id="@+id/list1"></ListView> 



</LinearLayout> 

Answer 1

在jenres2.setJenres，jenres3.setJenres等首先开始改变jenres.setJenres ..你只分配值jenres而不是2,3,4等。
