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.TextView;
 
public class MyFragment extends Fragment {
 
 
  @Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container,
      Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    View view = inflater.inflate(R.layout.myfragment, null);
    TextView tv_title = (TextView) view.findViewById(R.id.tv_title);
    //得到数据
    PersionInfo info = (PersionInfo) getArguments().getSerializable("info");
    tv_title.setText(info.getNameString());
    return view;
  }
}

2.写一个实体类：

  private boolean chick;  //标识
 
  public PersionInfo(String nameString) {
    this.nameString = nameString;
  }
 
  public String getNameString() {
    return nameString;
  }
 
  public void setNameString(String nameString) {
    this.nameString = nameString;
  }
 
  public boolean isChick() {
    return chick;
  }
 
  public void setChick(boolean chick) {
    this.chick = chick;
  }
 
}

3.写一个adapter

  public MyAdapter(Context context, List<PersionInfo> listinfos){
    this.context =context;
    this.listinfos = listinfos;
  }
 
  @Override
  public int getCount() {
    // TODO Auto-generated method stub
    return listinfos.size();
  }
 
  @Override
  public Object getItem(int position) {
    // TODO Auto-generated method stub
    return listinfos.get(position);
  }
 
  @Override
  public long getItemId(int position) {
    // TODO Auto-generated method stub
    return position;
  }
 
  @Override
  public View getView(int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    convertView = LayoutInflater.from(context).inflate(R.layout.listview_item, null);
    TextView tv = (TextView) convertView.findViewById(R.id.tv);
    PersionInfo persionInfo = listinfos.get(position);
    tv.setText(persionInfo.getNameString());
    if (persionInfo.isChick()) {
      convertView.setBackgroundResource(R.drawable.tongcheng_all_bg01);
    } else {
      convertView.setBackgroundColor(Color.parseColor("#f4f4f4"));
    }
    return convertView;
  }
}
