不管哪一款Android 设备都会在设置中显示关于手机一栏,基本上大同小异，手机名称啊，型号啊，版本号啊手机内存机身存储等等，以下是简单的记录下：

1.Activity：

2.Adapter：

package adapter;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.TextView;import com.vstar3d.myapplication.R;import java.util.List;public class Setting_AboutPhoneAdapter extends BaseAdapter {    private List
   
     itemDetailed;    private Context context;    public Setting_AboutPhoneAdapter(List
    
      itemDetailed, Context context) {        this.itemDetailed = itemDetailed;        this.context = context;    }    @Override    public int getCount() {        return itemDetailed.size();    }    @Override    public Object getItem(int position) {        return null;    }    @Override    public long getItemId(int position) {        return 0;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        ViewHolder viewHolder;        if (convertView == null){            convertView = LayoutInflater.from(context).inflate(R.layout.item,null);            viewHolder = new ViewHolder();            viewHolder.text_detailed = (TextView) convertView.findViewById(R.id.text_detailed);            convertView.setTag(viewHolder);        }else {            viewHolder = (ViewHolder) convertView.getTag();        }        String stringTitle = itemDetailed.get(position);        viewHolder.text_detailed.setText(stringTitle);        return convertView;    }    class ViewHolder{        TextView text_detailed;    }
    
   

3.布局文件：main

item：

至于还有一些法律信息等等信息加进去就行。
