我显示自定义了一个类继承Fragment：

+提示:

我的fragment内添加的是一个自定义的ListView的控件,下面给出我调用fragment的主界面布局和frament使用的布局以及listview每一条itme的布局：

下面给出我自定义listview的代码：

+提示: 自定义的ListView

最后就是自定义适配器了：

+提示:

-

package com.example.yuji_project_mcy.array_adapter;
import java.util.List;
import com.example.yuji_project_mcy.R;
import com.example.yuji_project_myc.listclass.NoteList;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
public class NoteAdapter extends ArrayAdapter<NoteList> {
private int resourceId;
public NoteAdapter(Context context, int textViewResourceId,
List<NoteList> objects) {
super(context, textViewResourceId, objects);
resourceId = textViewResourceId;
}
public View getView(int position, View convertView, ViewGroup parent) {
NoteList notelist = getItem(position);
View view;
ViewHolder viewHolder;
if (convertView == null) {
view = LayoutInflater.from(getContext()).inflate(resourceId, null);
viewHolder = new ViewHolder();
viewHolder.Post_Image = (ImageView) view
.findViewById(R.id.post_image);
viewHolder.Post_Name = (TextView) view.findViewById(R.id.post_name);
viewHolder.Poster_Name = (TextView) view
.findViewById(R.id.poster_name);
viewHolder.Tag_dttg = (TextView) view
.findViewById(R.id.post_tag_dttg);
viewHolder.Tag_qzdz = (TextView) view
.findViewById(R.id.post_tag_qzdz);
viewHolder.Tag_bbdz = (TextView) view
.findViewById(R.id.post_tag_bbdz);
viewHolder.Tag_htjl = (TextView) view
.findViewById(R.id.post_tag_htjl);
viewHolder.Tag_rmt = (TextView) view

viewHolder.Tag_fj = (TextView) view.findViewById(R.id.post_tag_fj);
viewHolder.Tag_jf = (TextView) view.findViewById(R.id.post_tag_jf);
view.setTag(viewHolder);
} else {
view = convertView;
viewHolder = (ViewHolder) view.getTag();
}
viewHolder.Post_Image.setImageResource(notelist.getPost_imageId());
viewHolder.Post_Name.setText(notelist.getPost_name());
viewHolder.Poster_Name.setText(notelist.getPoster_name());
if (notelist.isTag_bbdz())
viewHolder.Tag_bbdz.setVisibility(View.VISIBLE);
else
viewHolder.Tag_bbdz.setVisibility(View.GONE);
if (notelist.isTag_dttg())
viewHolder.Tag_dttg.setVisibility(View.VISIBLE);
else
viewHolder.Tag_dttg.setVisibility(View.GONE);
if (notelist.isTag_fj())
viewHolder.Tag_fj.setVisibility(View.VISIBLE);
else
viewHolder.Tag_fj.setVisibility(View.GONE);
if (notelist.isTag_htjl())
viewHolder.Tag_htjl.setVisibility(View.VISIBLE);
else
viewHolder.Tag_htjl.setVisibility(View.GONE);
if (notelist.isTag_jf())
viewHolder.Tag_jf.setVisibility(View.VISIBLE);
else
viewHolder.Tag_jf.setVisibility(View.GONE);
if (notelist.isTag_qzdz())
viewHolder.Tag_qzdz.setVisibility(View.VISIBLE);
else
viewHolder.Tag_qzdz.setVisibility(View.GONE);
if (notelist.isTag_rmt())
viewHolder.Tag_rmt.setVisibility(View.VISIBLE);
else
viewHolder.Tag_rmt.setVisibility(View.GONE);
return view;
}
class ViewHolder {
ImageView Post_Image;
TextView Post_Name;
TextView Poster_Name;
TextView Tag_qzdz;
TextView Tag_bbdz;
TextView Tag_rmt;
TextView Tag_jf;
TextView Tag_fj;
TextView Tag_htjl;
TextView Tag_dttg;
}
}

复制代码

对了，还有一个自定义的类，用来放item的ID，名称之类的：

+提示:

-

package com.example.yuji_project_myc.listclass;
public class NoteList {
private String post_name;
private String poster_name;
private int post_imageId;
private boolean tag_qzdz;
private boolean tag_bbdz;
private boolean tag_dttg;
private boolean tag_rmt;
private boolean tag_htjl;
private boolean tag_jf;
private boolean tag_fj;
public NoteList(String post_name, String poster_name, int post_imageId,
boolean tag_qzdz, boolean tag_bbdz, boolean tag_dttg,
boolean tag_rmt, boolean tag_htjl, boolean tag_jf, boolean tag_fj) {
this.post_name = post_name;
this.poster_name = poster_name;
this.post_imageId = post_imageId;
this.tag_qzdz = tag_qzdz;
this.tag_bbdz = tag_bbdz;
this.tag_dttg = tag_dttg;
this.tag_rmt = tag_rmt;
this.tag_htjl = tag_htjl;
this.tag_jf = tag_jf;
this.tag_fj = tag_fj;
}
public String getPost_name() {
return post_name;
}
public String getPoster_name() {
return poster_name;
}
public int getPost_imageId() {
return post_imageId;
}
public boolean isTag_qzdz() {
return tag_qzdz;
}
public boolean isTag_bbdz() {
return tag_bbdz;
}
public boolean isTag_dttg() {
return tag_dttg;
}
public boolean isTag_rmt() {
return tag_rmt;
}
public boolean isTag_htjl() {
return tag_htjl;
}
public boolean isTag_jf() {
return tag_jf;
}
public boolean isTag_fj() {
return tag_fj;
}
}

复制代码

然后DEBUG时到NoteAdapter的
viewHolder.Post_Image.setImageResource(notelist.getPost_imageId());
viewHolder.Post_Name.setText(notelist.getPost_name());
这里就开始出错，不知道为什么，请问是怎么回事？
