1.做一个天气的界面，填充内容

2.Style的使用，Android的常规认识

• 取得成就

1.天气界面主要用了几个Layout的嵌套，之后下面一个ListView，自定义adapter

2.Style常用于几个具有相同属性的组件时，在value -编写style文件

实例1：

//自定义适配器

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

import java.util.List;

public class WeatherAdapterextendsBaseAdapter {
    private int resourceID=0;
    private Context context=null;
    private List<Weather>list= null;
    public WeatherAdapter(Context context,intresourceID,List<Weather> list){
        this.context= context;
        this.resourceID=resourceID;
        this.list= list;
    }
    @Override
    public intgetCount() {
        return list.size();
    }

    @Override
    publicObject getItem(intposition) {
        return list.get(position);
    }

    @Override
    public longgetItemId(intposition) {
        return position;
    }

    @Override
    publicView getView(intposition, View convertView, ViewGroup parent) {
        Weather weather = (Weather) getItem(position);
        Holder holder = null;
        if (convertView ==null){
            convertView = LayoutInflater.from(context).inflate(resourceID,null);
            holder = new Holder();
            holder.image = (ImageView) convertView.findViewById(R.id.imageView_list);
            holder.windDirection = (TextView) convertView.findViewById(R.id.textView_windDirection_list);
            holder.day = (TextView) convertView.findViewById(R.id.textView_day_list);
            holder.publishTime = (TextView)convertView.findViewById(R.id.textView_publishtime_list);
            convertView.setTag(holder);
        }else{
            holder =(Holder)convertView.getTag();
        }
        holder.image.setImageResource(weather.imageID);
        holder.windDirection.setText(weather.windDirection);
        holder.day.setText(weather.day);
        holder.publishTime.setText(weather.publishTime);
        return convertView;
    }
}

class Holder{
    TextView weatherName;
    TextView location;
    ImageView image;
    TextView temperature;
    TextView windDirection;
    TextView publishTime;
    TextView day;
}

实例2：

<style name="textstyle">
    <item name="android:textSize">25sp</item>
    <item name="android:layout_alignParentRight">true</item>
    <item name="android:textAllCaps">false</item>
</style>
