跟着郑平老师做通讯录小项目时学到布局界面底部的控件

Posted 2022-06-10 江清清

界面底部整体是一个GirdView  一行一共五列，每一项是上面图片下面是Text

用SiampleAdapter进行加入

GirdView中每一项的布局如下：

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="wrap_content"

    android:orientation="horizontal"

    android:paddingBottom="5dip" >

 

    <ImageView

        android:id="@+id/item_image"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_centerHorizontal="true" />

 

    <TextView

        android:id="@+id/item_text"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_below="@+id/item_image"

        android:layout_centerHorizontal="true" />

 

</RelativeLayout>

Java代码如下：

package com.jiangqq;

 

import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;

import java.util.Map;

 

import android.app.Activity;

import android.os.Bundle;

import android.view.Gravity;

import android.widget.GridView;

import android.widget.SimpleAdapter;

 

public class GirdViewActivity extends Activity



private GridView gv_button_menu;

 

@Override

protected void onCreate(Bundle savedInstanceState) 

// TODO Auto-generated method stub

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

loadButtonMenu();



 

private void loadButtonMenu() 

gv_button_menu = (GridView) this.findViewById(R.id.gv_buttom_menu);

gv_button_menu.setBackgroundResource(R.drawable.channelgallery_bg);

// 设置每行的列数

gv_button_menu.setNumColumns(5);

gv_button_menu.setGravity(Gravity.CENTER);

gv_button_menu.setVerticalSpacing(10);

gv_button_menu.setHorizontalSpacing(10);

List data = new ArrayList();

Map map = new HashMap();

map.put("itemImage", R.drawable.menu_new_user);

map.put("itemText", "添加");

data.add(map);

map = new HashMap();

map.put("itemImage", R.drawable.menu_search);

map.put("itemText", "查找");

data.add(map);

map = new HashMap();

map.put("itemImage", R.drawable.menu_delete);

map.put("itemText", "删除");

data.add(map);

map = new HashMap();

map.put("itemImage", R.drawable.controlbar_showtype_list);

map.put("itemText", "菜单");

data.add(map);

map = new HashMap();

map.put("itemImage", R.drawable.menu_exit);

map.put("itemText", "退出");

data.add(map);

 

SimpleAdapter adapter = new SimpleAdapter(this, data,

R.layout.item_menu, new String[]  "itemImage", "itemText", ,

new int[]  R.id.item_image, R.id.item_text );

gv_button_menu.setAdapter(adapter);






最后说一下 郑平老师讲的也不错，这两天连续做了三个小项目，也学到了很多东西，要好总结一下
