[android] 天气app布局练习（二）

概述主要练习一下GridView MainActivity.java activity_main.xml main_grid_item.xml

主要练习一下GrIDVIEw

MainActivity.java

package com.example.weatherreport;import java.util.ArrayList; java.util.HashMap; java.util.List; java.util.Map; androID.app.Activity; androID.os.Bundle; androID.Widget.GrIDVIEw; androID.Widget.SimpleAdapter;public class MainActivity extends Activity {    private GrIDVIEw gv_airs;    @OverrIDe    protected voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentVIEw(R.layout.activity_main);        gv_airs=(GrIDVIEw) findVIEwByID(R.ID.gv_airs);        makeGrIDVIEw();    }    /**     * 组装GrIDVIEw     */    private  makeGrIDVIEw() {        List<Map<String,String>> data=new ArrayList<>();        Map<String,String> item=null;        item=new HashMap<>();        item.put("Title","83");        item.put("desc","湿度(%)");        data.add(item);                item=);        data.add(item);                SimpleAdapter adapter=new SimpleAdapter(this,data,R.layout.main_grID_item,new String[]{"Title","desc"},1)">new int[]{R.ID.tv_Title,R.ID.tv_desc});        gv_airs.setAdapter(adapter);    }}

activity_main.xml

main_grID_item.xml

<?xml version="1.0" enCoding="utf-8"?>    androID:layout_marginleft        androID:paddingtop="25dp"        androID:paddingBottom        androID:layout_centerInParent        androID:gravity="center"="vertical" ="@+ID/tv_desc"            androID:layout_wIDth="湿度(%)"            androID:textSize="12sp" ="@+ID/tv_Title"="83"="22sp" >>
