仿win8磁贴界面以及功能

做移动产品界面占很大的一部分，同时也是决定一款产品好的的重要因素，最近看见有人放win8的界面效果，搜了两款，一款是只是仿界面没有特效，另一款是自定义组件能够实现反转效果，今天分析一下这两类界面。

仿win8界面

win8磁贴类似九宫格效果，实现这种效果基本上有三种方式实现：LinearLayout，使用其属性layout_weight实现等分；TableLayout，做过计算器的人可能会用到过这个，也可以实现，还有一种就是GridView,自己实现适配器，我找到的仿win8界面使用LinearLayout来实现的，LinearLayout层层嵌套，这种方式不太提倡，因为嵌套太多，我们看一下界面效果：



我们看一下界面源码：

<?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"    android:paddingTop="30dp"    android:paddingBottom="30dp"    android:paddingLeft="20dp"    android:baselineAligned="false"    android:background="@drawable/rootblock_default_bg"    >    <LinearLayout      android:layout_width="wrap_content"     android:layout_height="fill_parent"     android:orientation="vertical"     android:layout_weight="1">     <LinearLayout          android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:orientation="horizontal">             <LinearLayout              android:layout_width="108dp"             android:layout_height="108dp"             android:background="#FF7F24">         </LinearLayout>             <LinearLayout              android:layout_width="108dp"             android:layout_height="108dp"             android:layout_marginLeft="5dp"             android:background="#FF7F24">         </LinearLayout>     </LinearLayout>             <LinearLayout          android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:layout_marginTop="5dp"         android:orientation="horizontal">        <LinearLayout              android:layout_width="108dp"             android:layout_height="108dp"             android:background="#3399ff">         </LinearLayout>             <LinearLayout              android:layout_width="108dp"             android:layout_height="108dp"             android:layout_marginLeft="5dp"             android:background="#3399ff">         </LinearLayout>     </LinearLayout>           <LinearLayout          android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:layout_marginTop="5dp"         android:orientation="horizontal">       <LinearLayout              android:layout_width="108dp"             android:layout_height="108dp"             android:background="#3399ff">         </LinearLayout>             <LinearLayout              android:layout_width="108dp"             android:layout_height="108dp"             android:layout_marginLeft="5dp"             android:background="#3399ff">         </LinearLayout>     </LinearLayout>      <LinearLayout          android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:layout_marginTop="5dp"         android:orientation="horizontal">      <LinearLayout          android:layout_width="108dp"          android:layout_height="108dp"          android:background="#953399ff" >      </LinearLayout>             <LinearLayout              android:layout_width="108dp"             android:layout_height="108dp"             android:layout_marginLeft="5dp"             android:background="#953399ff">         </LinearLayout>     </LinearLayout>              </LinearLayout>    <LinearLayout         android:layout_width="wrap_content"        android:layout_height="fill_parent"        android:orientation="vertical"        android:layout_weight="1">       <RelativeLayout            android:layout_width="fill_parent"           android:layout_height="fill_parent"           >         <LinearLayout         android:layout_width="wrap_content"           android:layout_height="wrap_content"           android:orientation="vertical"             android:layout_alignParentBottom="true">       <ImageView           android:id="@+id/download_btn"         android:layout_width="36dp"       android:layout_height="36dp"       android:src="@drawable/rootblock_icon_download_bg"/>       <ImageView           android:id="@+id/download_btn"         android:layout_width="36dp"       android:layout_height="36dp"       android:layout_marginTop="20dp"       android:src="@drawable/rootblock_icon_clear_bg"/>       <ImageView           android:id="@+id/download_btn"         android:layout_width="36dp"       android:layout_height="36dp"       android:layout_marginTop="20dp"       android:src="@drawable/rootblock_icon_set_bg"/>       <ImageView           android:id="@+id/download_btn"        android:layout_width="36dp"       android:layout_height="36dp"       android:layout_marginTop="20dp"       android:src="@drawable/rootblock_icon_add_bg"/>        </LinearLayout>       </RelativeLayout>     </LinearLayout></LinearLayout>

从源码上看，分了左右两部分，左边使用LinearLayout进行嵌套，不过其宽度和高度都是108dp，固定的不好，如果是在Pad上面界面就不太和谐了，就要写几套布局来实现。

我重写改了一下，代码如下：

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"

采取分方式就是layout_weight嵌套，虽然这种方式官方不提倡，不过可以有很好的适应性。

自定义，实现仿win8磁贴功能

我找到的这个源码效果很绚丽，自定义组件式通过继承ImageView来实现的，因为ImageView本身是有可以使用Matix进行缩放和旋转功能，缺点就是只能放图片，所以如果用这个源码你必须把主界面的模块布局用图片的形式展现，下面看看它的实现效果：

实现原理很简单，功能分为缩放和旋转，当点击中间区域实现缩放，点击两侧实现旋转，这个可以根据组件的宽度和高度以及点击的位置来判断，源码如下：

package com.ljp.ani;import android.annotation.SuppressLint;import android.content.Context;import android.graphics.Camera;import android.graphics.Canvas;import android.graphics.Matrix;import android.graphics.Paint;import android.graphics.PaintFlagsDrawFilter;import android.graphics.drawable.BitmapDrawable;import android.graphics.drawable.Drawable;import android.os.Handler;import android.os.Message;import android.util.AttributeSet;import android.view.MotionEvent;import android.widget.ImageView;@SuppressLint("HandlerLeak")public class MagnetView extends ImageView {private boolean onAnimation = true;private int rotateDegree = 10;private PaintFlagsDrawFilter filter;private boolean isFirst = true;private float minScale = 0.95f;private int vWidth;private int vHeight;private boolean isFinish = true, isActionMove = false, isScale = false;private Camera camera;boolean XbigY = false;float RolateX = 0;float RolateY = 0;OnViewClick onclick = null;public MagnetView(Context context) {super(context);camera = new Camera();filter = new PaintFlagsDrawFilter(0, Paint.ANTI_ALIAS_FLAG| Paint.FILTER_BITMAP_FLAG);}public MagnetView(Context context, AttributeSet attrs) {super(context, attrs);camera = new Camera();filter = new PaintFlagsDrawFilter(0, Paint.ANTI_ALIAS_FLAG| Paint.FILTER_BITMAP_FLAG);}public void SetAnimationOnOff(boolean oo) {onAnimation = oo;}public void setOnClickIntent(OnViewClick onclick) {this.onclick = onclick;}@Overrideprotected void onDraw(Canvas canvas) {super.onDraw(canvas);if (isFirst) {isFirst = false;init();}canvas.setDrawFilter(filter);}public void init() {vWidth = getWidth() - getPaddingLeft() - getPaddingRight();vHeight = getHeight() - getPaddingTop() - getPaddingBottom();Drawable drawable = getDrawable();BitmapDrawable bd = (BitmapDrawable) drawable;bd.setAntiAlias(true);}@Overridepublic boolean onTouchEvent(MotionEvent event) {super.onTouchEvent(event);if (!onAnimation)return true;switch (event.getAction() & MotionEvent.ACTION_MASK) {case MotionEvent.ACTION_DOWN:float X = event.getX();float Y = event.getY();RolateX = vWidth / 2 - X;RolateY = vHeight / 2 - Y;XbigY = Math.abs(RolateX) > Math.abs(RolateY) ?

布局代码：

<?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:background="@drawable/bkg_img_default"    android:gravity="center"    android:orientation="vertical" >    <LinearLayout        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:orientation="vertical" >        <LinearLayout            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:orientation="horizontal" >            <LinearLayout                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:orientation="vertical" >                <com.ljp.ani.MagnetView                    android:id="@+id/c_joke"                    android:layout_width="wrap_content"                    android:layout_height="wrap_content"                    android:layout_margin="2dp"                    android:scaleType="matrix"                    android:src="@drawable/left_top" />                <com.ljp.ani.MagnetView                    android:id="@+id/c_idea"                    android:layout_width="wrap_content"                    android:layout_height="wrap_content"                    android:layout_margin="2dp"                    android:scaleType="matrix"                    android:src="@drawable/left_bottom" />            </LinearLayout>            <com.ljp.ani.MagnetView                android:id="@+id/c_constellation"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:layout_margin="2dp"                android:scaleType="matrix"                android:src="@drawable/right" />        </LinearLayout>        <com.ljp.ani.MagnetView            android:id="@+id/c_recommend"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_margin="2dp"            android:scaleType="matrix"            android:src="@drawable/bottom" />    </LinearLayout></LinearLayout>

其实布局跟第一种情况一样，只是组件换成自己定义的组件，多的只是自定义组件的点击效果。
