Android QQ空间(Apad)项目总结---应用UI框架的搭建


图1:交互效果图.


从上图可以看出,整个应用其实UI框架相对比较简单,可以分为俩部分,左侧导航栏区域,右侧显示内容区域。当我们点击左侧导航栏时,右侧显示相对应内容。

应用的主要内容分为四个模块:好友动态;个人主页;好友列表;应用中心。右侧显示内容则统一由一个管理器管理,管理器管理了右侧的容器以及显示内容面板。

也许用文字不太好说清楚,所以我写了一个简单的Demo以及画了一个UI结构图方便大家理解:

首先是新建一个Android工程,命名为QzoneFrameDemo,结构如下:



图2:程序代码结构图:

为了更容易理解代码,我画了一个各个类的关系图如下:



上图可以清晰的看清各个类之间的关系,其中QZRightWindowManger管理了QZRightWindowContainer(剪头忘记加了)和右侧的四个Window,QZRightWindowContainer继承了FrameLayout,四个Window继承了QZRightWindowBase。

其中QZRightWindowContainer代码如下(继承了FrameLayout):

view plain
package com.tutor.frame;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.FrameLayout;

public class QZRightWindowContainer extends FrameLayout {

public QZRightWindowContainer(Context context){
super(context);
}
public QZRightWindowContainer(Context context, AttributeSet attrs) {
super(context, attrs);
}

}


而右侧四个Window的基类QZRightWindowBase的代码如下:

view plain
package com.tutor.frame;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.FrameLayout;
import android.widget.TextView;

public abstract class QZRightWindowBase extends FrameLayout {

public TextView mContentTextView;

private LayoutParams params = new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT);

public QZRightWindowBase(Context context){
super(context);
setupViews();
}

public QZRightWindowBase(Context context, AttributeSet attrs) {
super(context, attrs);
setupViews();
}

private void setupViews(){
mContentTextView = new TextView(getContext());
mContentTextView.setLayoutParams(params);
}

//做些事为了扩展举例而已
public abstract void dosomething();
//做些事2
public abstract void dosomething2();

}
右侧窗口Window1即QZRightWindow1代码(其他的都一样不贴代码了)如下:
view plain
package com.tutor.frame;

import android.content.Context;
import android.graphics.Color;
import android.util.AttributeSet;

public class QZRightWindow1 extends QZRightWindowBase{

public QZRightWindow1(Context context){
super(context);
setupViews();
}
public QZRightWindow1(Context context, AttributeSet attrs) {
super(context, attrs);
setupViews();
}

private void setupViews(){
mContentTextView.setText("好友动态");
mContentTextView.setBackgroundColor(Color.RED);
addView(mContentTextView);
}

@Override
public void dosomething() {
// TODO Auto-generated method stub

}

@Override
public void dosomething2() {
// TODO Auto-generated method stub

}

}

管理QZRightWindowContainer和右侧四个Window的管理类QZRightWindowManager代码如下:
view plain
package com.tutor.frame;

import java.util.HashMap;
import java.util.Iterator;

import android.view.View;




public class QZRightWindowManager {

/**
* 好友动态面板的KEY
*/
public static final int FRIEND_TRENDS_WINDOW = 0;

/**
* 个人中心面板的KEY
*/
public static final int HOME_PAGE_WINDOW = 1;

/**
* 好友关系链面板的KEY
*/
public static final int FRIEND_LIST_WINDOW = 2;

/**
* 应用中心面板的KEY
*/
public static final int APP_CENTER_WINDOW = 3;


private HashMap<Integer, QZRightWindowBase> mHashMap;

private QZRightWindowContainer mContainer;


public QZRightWindowManager(){
mHashMap = new HashMap<Integer, QZRightWindowBase>();
}

public void setmContainer(QZRightWindowContainer container) {
this.mContainer = container;
}

public void showRightWindow(int num,QZRightWindowBase mQzRightWindowBase){
if(!mHashMap.containsKey(num)){
mHashMap.put(num, mQzRightWindowBase);
if(!(mQzRightWindowBase instanceof QZRightWindow1)){
mContainer.addView(mQzRightWindowBase);
}
}

for (Iterator iter = mHashMap.keySet().iterator(); iter.hasNext();) {
Object key = iter.next();
QZRightWindowBase qzb = mHashMap.get(key);
qzb.setVisibility(View.INVISIBLE);
}

mQzRightWindowBase.setVisibility(View.VISIBLE);
}

}

主程序QzoneFrameDemoActivity代码如下:
view plain
package com.tutor.framedemo;

import com.tutor.frame.QZLeftNavBar;
import com.tutor.frame.QZRightWindow1;
import com.tutor.frame.QZRightWindow2;
import com.tutor.frame.QZRightWindow3;
import com.tutor.frame.QZRightWindow4;
import com.tutor.frame.QZRightWindowBase;
import com.tutor.frame.QZRightWindowContainer;
import com.tutor.frame.QZRightWindowManager;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;

public class QzoneFrameDemoActivity extends Activity implements OnClickListener{

private QZRightWindow1 mQzRightWindow1;

private QZRightWindow2 mQzRightWindow2;

private QZRightWindow3 mQzRightWindow3;

private QZRightWindow4 mQzRightWindow4;

private QZLeftNavBar mQzLeftNavBar;

private QZRightWindowContainer mQzRightWindowContainer;

private QZRightWindowManager mQzRightWindowManager;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

setupViews();
}

private void setupViews(){
mQzRightWindowManager = new QZRightWindowManager();

mQzLeftNavBar = (QZLeftNavBar)findViewById(R.id.navbar);

mQzLeftNavBar.findViewById(R.id.rw1).setOnClickListener(this);
mQzLeftNavBar.findViewById(R.id.rw2).setOnClickListener(this);
mQzLeftNavBar.findViewById(R.id.rw3).setOnClickListener(this);
mQzLeftNavBar.findViewById(R.id.rw4).setOnClickListener(this);

mQzRightWindow1 = (QZRightWindow1)findViewById(R.id.qzrw1);

mQzRightWindowContainer = (QZRightWindowContainer)findViewById(R.id.container);
mQzRightWindowManager.setmContainer(mQzRightWindowContainer);
}

private void showRightWindow(int num,QZRightWindowBase mQzRightWindowBase){
mQzRightWindowManager.showRightWindow(num, mQzRightWindowBase);
}

@Override
public void onClick(View v) {
int id = v.getId();
switch (id) {
case R.id.rw1:
showRightWindow(QZRightWindowManager.FRIEND_TRENDS_WINDOW, mQzRightWindow1);
break;
case R.id.rw2:
if(mQzRightWindow2 == null){
mQzRightWindow2 = new QZRightWindow2(this);
}
showRightWindow(QZRightWindowManager.HOME_PAGE_WINDOW, mQzRightWindow2);
break;
case R.id.rw3:
if(mQzRightWindow3 == null){
mQzRightWindow3 = new QZRightWindow3(this);
}
showRightWindow(QZRightWindowManager.FRIEND_LIST_WINDOW, mQzRightWindow3);
break;
case R.id.rw4:
if(mQzRightWindow4 == null){
mQzRightWindow4 = new QZRightWindow4(this);
}
showRightWindow(QZRightWindowManager.APP_CENTER_WINDOW, mQzRightWindow4);
break;
default:
break;
}
}
}

主程序所用到的布局文件main.xml代码如下:
view plain
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >

<com.tutor.frame.QZLeftNavBar
android:id="@+id/navbar"
android:layout_width="wrap_content"
android:layout_height="fill_parent"/>

<com.tutor.frame.QZRightWindowContainer
android:id="@+id/container"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<com.tutor.frame.QZRightWindow1
android:id="@+id/qzrw1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</com.tutor.frame.QZRightWindowContainer>
</LinearLayout>

运行效果如下:


效果1



效果2.

OK,这样就大功告成了!对于pad上面的应用,单Activity化,各个功能模块化,UI控件化,是比较好的选择,这样可以加大开发效率,减少和其他同学的耦合性。
