实现一个简单但是好看的滑动栏

 哈哈，终于把滑动栏做好了，但是没有手势的滑动，只有点击按钮的效果，不过，我觉得还不错了！

这个就是我应用中用到的滑动栏的效果！，在这里我就share一下咯！

大家看代码就知道他的详细情况了：

这里我们有一个主类，这里会有两个布局文件与它相连：

 

这里显示main_slide布局文件：

请记住这里要用到framlayout哦！

              

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

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

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:background="#ffffff" >

 

    <!-- 左边菜单 -->

 

    <RelativeLayout

        <Button

            android:id="@+id/btn_fav"

            android:layout_width="230dip"

            android:layout_height="40dip"

            android:layout_below="@id/text_moto"

            android:layout_centerHorizontal="true"

        <Button

            android:background="@drawable/comment" />

 

        <Button

    </RelativeLayout>

 

    <grimbo.android.demo.slidingmenu.MyHorizontalScrollView

        android:id="@+id/myScrollView"

        android:layout_width="fill_parent"

        android:layout_height="fill_parent"

        android:fadingEdge="none"

        android:scrollbars="none" >

 

        <!--

        这里按钮就是控制滑图案出来的背景颜色，当然，如果这里没有了背景颜色，就会以上面的

        背景颜色为主

        -->

 

        <LinearLayout

            android:id="@+id/top"

            android:layout_width="fill_parent"

            android:layout_height="fill_parent"

            android:orientation="horizontal" >

        </LinearLayout>

    </grimbo.android.demo.slidingmenu.MyHorizontalScrollView>

 

</FrameLayout>

接下来就是main布局文件：这个布局文件就是显示我们当前不做任何操作显示的界面：

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

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

    android:id="@+id/app"

    android:layout_width="fill_parent"

    android:layout_height="wrap_content"

    android:background="#00f"

    android:orientation="vertical" >

 

    <RelativeLayout

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:orientation="horizontal"

        android:paddingLeft="2dip" 

        android:paddingTop="4dip"

        >

 

        <ImageView

            android:id="@+id/leftButton"

            android:layout_width="60dip"

            android:layout_height="60dip" />

    </RelativeLayout>

 

</LinearLayout>

这里还会有一些对当前界面滑动后的界面美观维护类：

package grimbo.android.demo.slidingmenu;

 

import grimbo.android.demo.slidingmenu.MyHorizontalScrollView.SizeCallback;

import android.widget.ImageView;

 

/**

 * All rights reserved.

 */

public class SizeCallbackForMenu implements SizeCallback {

    private ImageView leftButton;

    private int leftButtonWidth;

 

    public SizeCallbackForMenu(ImageView leftButton) {

        super();

        this.leftButton = leftButton;

    }

 

    @Override

    public void onGlobalLayout() {

     leftButtonWidth = leftButton.getMeasuredWidth()+8;

        System.out.println("leftButtonWidth=" + leftButtonWidth);

    }

 

    @Override

    public void getViewSize(int idx, int w, int h, int[] dims) {

        dims[0] = w;

        dims[1] = h;

        if (idx != 1) {

         //当视图不是中间的视图

            dims[0] = w - leftButtonWidth;

        }

    }

}

 

 

这里其实对于大家最重要的就是动画了，所以这里我把动画公布了：

 

这里面的代码依次为：

 

 

第一个：

 

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

 

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

<translate android:fromXDelta="80%p" android:toXDelta="0" android:duration="500"/>

<!--alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="300" /-->

</set>

 

第二个：

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

 

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

<!--alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="300" /-->

</set>

第三个：

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

第六个：

</set>

但是鉴于这么多的代码，毕竟很无趣嘛，我会看情况吧源码贴出来的！谢谢支持哦！有什么好的建议随便说了！
