Android学习10-----Android组件通信 (3) ActivityGroup

导航栏在 Android 中的应用是很常见的，前面我们学习 Android 组件时发现 TabHost 组件是可以完成的，但是 TabHost 组件在操作中因为其使用困难，所以一般不会作为界面分页框架的首选，使用最多的是 ActivityGroup 与 GridView 相结合的方式完成。

         每一个 Activity 程序都是采用屏幕独占的方式运行的，而使用 ActivityGroup 就可以让多个 Activity 同事运行在一个屏幕上，而且每一个 Activity 还会继续独立的工作，在 Android 之中专门为用户提供了 android.app. ActivityGroup 类。

         可以简单的理解为一个 ActivityGroup 中就包含了多个 Activity 程序。

ActivityGroup 类中常用方法：

No.	方法	描述
1	public Activity getCurrentActivity()	取得当前的 Activity 对象
2	public final LocalActivityManager getLocalActivityManager	取得 LocalActivityManager 类的对象

 

一、基本菜单展示，为了方便，我们把所有菜单都跳转到一个 Activity 程序之中

mylayout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
	xmlns:android="http://schemas.android.com/apk/res/android"
	android:orientation="vertical" 
	android:layout_width="fill_parent"
	android:layout_height="fill_parent">
	<ImageView 
		android:layout_width="fill_parent"
		android:layout_height="wrap_content" 
		android:src="@drawable/android_book" />
</LinearLayout>

 

MyActivity.java(读取mylayout图片)

package com.iflytek.demo;

import android.app.Activity;
import android.os.Bundle;

public class MyActivity extends Activity {
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		super.setContentView(R.layout.mylayout);
	}
}

 

main.xml(整体程序的布局文件)

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
	xmlns:android="http://schemas.android.com/apk/res/android"
	android:orientation="vertical" 
	android:layout_width="fill_parent"
	android:layout_height="fill_parent">
	<RelativeLayout 
		xmlns:android="http://schemas.android.com/apk/res/android"
		android:layout_width="fill_parent"
		android:layout_height="fill_parent">
		<LinearLayout 
			xmlns:android="http://schemas.android.com/apk/res/android"
			android:id="@+id/content"
			android:orientation="vertical" 
			android:layout_width="fill_parent"
			android:layout_height="fill_parent">
		</LinearLayout>
		<GridView
			android:id="@+id/gridviewbar" 
			android:layout_width="fill_parent"
			android:layout_height="wrap_content"
			android:layout_alignParentBottom="true"
			android:fadingEdgeLength="5px"
			android:fadingEdge="vertical"/>
	</RelativeLayout>
</LinearLayout>

 

下面关键在于如何处理GridView中显示的内容，对于内容只能由用户自己定义一个内容的填充器完成。
MenuImageAdapter.java

package com.iflytek.demo;

import android.view.View;

			this.menuImg[i].setImageResource(imgIds[i]);// 设置显示图片
		}
	}

	@Override
	public int getCount() {
		return this.menuImg.length;
	}

	@Override

	}

	public void setFocus(int selId) {

二、弹出菜单（进一步扩展菜单项）
有时候可以发现菜单项太多了，只能在原来的基础上弹出一个子菜单。
为了操作更加专业，下面定义strings.xml文件，增加一些文字性的信息
strings.xml

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

    <string name="hello">Hello World, ActivityGroup02Activity!</string>
    <string name="app_name">弹出菜单</string>
    <string name="popmenu_common">常用</string>
    <string name="popmenu_set">设置</string>
    <string name="popmenu_tool">工具</string>

</resources>

 下面就要继续开发满足于标题显示的适配器类
PopupMenuTitleAdapter.java

package com.iflytek.demo;

import android.content.Context;
import android.graphics.drawable.ColorDrawable;
import android.view.Gravity;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;

/**
 * 
 * @author xdwang
 * 
 * @create 2012-10-24 下午11:24:00
 * 
 * @email:[email protected]
 * 
 * @description 标题显示的适配器
 * 
 */
public class PopupMenuTitleAdapter extends BaseAdapter {
	/**
	 * 文字显示组件
	 */
	private TextView menuTitle[] = null;
	/**
	 * 文字显示的颜色
	 */
	private int fontColor;
	/**
	 * 选中的颜色
	 */
	private int selectedColor;
	/**
	 * 未选中的颜色
	 */
	private int unSelectedColor;

	public PopupMenuTitleAdapter(Context context, int[] titleIds,
			int fontColor, int fontSize, int selectedColor, int unSelectedColor) {
		this.fontColor = fontColor;
		this.selectedColor = selectedColor;
		this.unSelectedColor = unSelectedColor;
		this.menuTitle = new TextView[titleIds.length];
		for (int i = 0; i < titleIds.length; i++) {
			this.menuTitle[i] = new TextView(context);
			this.menuTitle[i].setText(titleIds[i]);
			this.menuTitle[i].setTextSize(fontSize);
			this.menuTitle[i].setGravity(Gravity.CENTER);
			this.menuTitle[i].setPadding(10, 10, 10, 10);
		}
	}

	@Override
	public int getCount() {
		return this.menuTitle.length;
	}

	@Override
	public Object getItem(int position) {
		return this.menuTitle[position];
	}

	@Override
	public long getItemId(int position) {
		return this.menuTitle[position].getId();
	}

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		View view = null;
		if (convertView == null) {
			view = this.menuTitle[position];
		} else {
			view = convertView;
		}
		return view;
	}

	public void setFocus(int index) {
		for (int i = 0; i < this.menuTitle.length; i++) {
			if (i != index) {
				this.menuTitle[i].setBackgroundDrawable(new ColorDrawable(
						this.unSelectedColor));
				this.menuTitle[i].setTextColor(fontColor);
			}
		}
		this.menuTitle[index].setBackgroundColor(0x00);
		this.menuTitle[index].setTextColor(this.selectedColor);
	}
}

 

下面定义菜单主体项的适配器
PopupMenuBodyAdapter.java

package com.iflytek.demo;

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

/**
 * 
 * @author xdwang
 * 
 * @create 2012-10-24 下午11:31:28
 * 
 * @email:[email protected]
 * 
 * @description 菜单主题项的适配器
 * 
 */
public class PopupMenuBodyAdapter extends BaseAdapter {
	/**
	 * 所有图片
	 */
	private ImageView[] menuImg = null;

	public PopupMenuBodyAdapter(Context context, int[] picIds) {
		this.menuImg = new ImageView[picIds.length];
		for (int i = 0; i < this.menuImg.length; i++) {
			this.menuImg[i] = new ImageView(context);
			this.menuImg[i].setImageResource(picIds[i]);
		}
	}

	@Override
	public int getCount() {
		return this.menuImg.length;
	}

	@Override
	public Object getItem(int position) {
		return this.menuImg[position];
	}

	@Override
	public long getItemId(int position) {
		return this.menuImg[position].getId();
	}

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		View view = null;
		if (convertView == null) {
			view = this.menuImg[position];
		} else {
			view = convertView;
		}
		return view;
	}

}

 

现在两个适配器搞定之后，下面最重要的就是弹出的窗口了。
现在之前的popupWindow组件已经不能被现在的操作所使用，所以必须扩充功能，扩充组件。
