  首先我们看下面视图：

  这种效果大家都不陌生，网上好多都说是仿人人网的，估计人家牛逼出来的早吧，我也参考了一一些例子，实现起来有三种方法，我下面简单介绍下：





  方法一： 其实就是对GestureDetector手势的应用及布局文件的设计 .





  布局文件main.xml    采用RelativeLayout布局.



```

<?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=“fill_parent” android:orientation=“vertical” >

<span class="tag">&lt;<span class="title">LinearLayout

android:id=”@+id/layout_right" android:layout_width=“fill_parent” android:layout_height=“fill_parent” android:layout_marginLeft=“50dp” android:orientation=“vertical” >

    <span class="tag">&lt;<span class="title">AbsoluteLayout

android:layout_width=“fill_parent” android:layout_height=“wrap_content” android:background="@color/grey21" android:padding=“10dp” >

        <span class="tag">&lt;<span class="title">TextView

android:layout_width=“wrap_content” android:layout_height=“wrap_content” android:text=“设置” android:textColor="@android:color/background_light" android:textSize=“20sp” /> </AbsoluteLayout>

    <span class="tag">&lt;<span class="title">ListView

android:id="@+id/lv_set" android:layout_width=“fill_parent” android:layout_height=“fill_parent” android:layout_weight=“1” > </ListView> </LinearLayout>

<span class="tag">&lt;<span class="title">LinearLayout

android:id="@+id/layout_left" android:layout_width=“fill_parent” android:layout_height=“fill_parent” android:background="@color/white" android:orientation=“vertical” >

    <span class="tag">&lt;<span class="title">RelativeLayout

android:layout_width=“fill_parent” android:layout_height=“wrap_content” android:background="@drawable/nav_bg" >

        <span class="tag">&lt;<span class="title">ImageView

android:id="@+id/iv_set" android:layout_width=“wrap_content” android:layout_height=“wrap_content” android:layout_alignParentRight=“true” android:layout_alignParentTop=“true” android:src="@drawable/nav_setting" />

        <span class="tag">&lt;<span class="title">TextView

android:layout_width=“wrap_content” android:layout_height=“wrap_content” android:layout_centerInParent=“true” android:text=“我” android:textColor="@android:color/background_light" android:textSize=“20sp” /> </RelativeLayout>

    <span class="tag">&lt;<span class="title">ImageView

android:id="@+id/iv_set" android:layout_width=“fill_parent” android:layout_height=“fill_parent” android:scaleType=“fitXY” android:src="@drawable/bg_guide_5" /> </LinearLayout>

</RelativeLayout>

    
    

      ![](http://img0.tuicool.com/QfYjYf.png)layout_right ：这个大布局文件， layout_left:距离左边50dp像素.(我们要移动的是 layout_left ).
    

    
    

      看到这个图我想大家都很清晰了吧，其实: 我们就是把layout_left这个布局控件整理向左移动，至于移动多少，就要看layout_right有多宽了。layout_left移动到距离左边的边距就是layout_right的宽及-MAX_WIDTH.相信大家都理解.
    

    
    

      布局文件就介绍到这里，下面看代码.
    

    
    ```
<span class="javadoc">/***
   * 初始化view
   */</span>
  <span class="keyword">void</span> InitView() {
    layout_left = (LinearLayout) findViewById(R.id.layout_left);
    layout_right = (LinearLayout) findViewById(R.id.layout_right);
    iv_set = (ImageView) findViewById(R.id.iv_set);
    lv_set = (ListView) findViewById(R.id.lv_set);
    lv_set.setAdapter(<span class="keyword">new</span> ArrayAdapter&lt;String&gt;(<span class="keyword">this</span>, R.layout.item,
        R.id.tv_item, title));
    lv_set.setOnItemClickListener(<span class="keyword">new</span> OnItemClickListener() {

      <span class="annotation">@Override</span>
      <span class="keyword">public</span> <span class="keyword">void</span> onItemClick(AdapterView&lt;?&gt; parent, View view,
          <span class="keyword">int</span> position, <span class="keyword">long</span> id) {
        Toast.makeText(MainActivity.<span class="keyword">this</span>, title[position], <span class="number">1</span>).show();
      }
    });
    layout_left.setOnTouchListener(<span class="keyword">this</span>);
    iv_set.setOnTouchListener(<span class="keyword">this</span>);
    mGestureDetector = <span class="keyword">new</span> GestureDetector(<span class="keyword">this</span>);
    <span class="comment">// 禁用长按监听</span>
    mGestureDetector.setIsLongpressEnabled(<span class="keyword">false</span>);
    getMAX_WIDTH();
  }

  这里要对手势进行监听，我想大家都知道怎么做，在这里我要说明一个方法：



```

/***

获取移动距离移动的距离其实就是layout_left的宽度 */ void getMAX_WIDTH() { ViewTreeObserver viewTreeObserver = layout_left.getViewTreeObserver(); // 获取控件宽度 viewTreeObserver.addOnPreDrawListener(new OnPreDrawListener() { @Override public boolean onPreDraw() { if (!hasMeasured) { window_width = getWindowManager().getDefaultDisplay() .getWidth(); RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams) layout_left .getLayoutParams(); layoutParams.width = window_width; layout_left.setLayoutParams(layoutParams); MAX_WIDTH = layout_right.getWidth(); Log.v(TAG, “MAX_WIDTH=" + MAX_WIDTH + “width=" + window_width); hasMeasured = true; } return true; } });

}

    
    

      在这里我们要获取屏幕的宽度，并将屏幕宽度设置给layout_left这个控件，为什么要这么做呢 ， 因为如果不把该控件宽度写死的话，那么系统将认为layout_left会根据不同环境宽度自动适应，也就是说我们通过layout_left.getLayoutParams动态移动该控件的时候，该控件会伸缩而不是移动。 描述的有点模糊，大家请看下面示意图就明白了.
    

    
    

      我们不为 layout_left定义死宽度效果：
    

    
    

      ![](http://img1.tuicool.com/ziAjIr.png)      ![](http://img0.tuicool.com/VrqI32.png)
    

    
    

      getLayoutParams可以很清楚看到， layout_left被向左拉伸了，并不是我们要的效果.
    

    
    

      还有一种解决办法就是我们在配置文件中直接把 layout_left宽度写死，不过这样不利于开发，因为分辨率的问题.因此就用 ViewTreeObserver进行对 layout_left设置宽度.
    

    
    

      ViewTreeObserver,这个类主要用于对布局文件的监听.强烈建议同学们参考这篇文章  [android ViewTreeObserver详细讲解](http://blog.csdn.net/jj120522/article/details/8097133)，相信让你对ViewTreeObserver有更一步的了解.其他的就是对 GestureDetector手势的应用，下面我把代码贴出来：

  上面代码注释已经很明确，相信大家都看的明白，我就不过多解释了。效果图： 截屏出来有点卡，不过在手机虚拟机上是不卡的.

  [源码下载](http://download.csdn.net/detail/jj120522/4670568)





  怎么样，看着还行吧，我们在看下面一个示例：





  ![](http://img1.tuicool.com/vaYRbe.png)





  简单说明一下，当你滑动的时候左边会跟着右边一起滑动，这个效果比上面那个酷吧，上面那个有点死板，其实实现起来也比较容易，只需要把我们上面那个稍微修改下，对layout_right也进行时时更新，这样就实现了这个效果了，如果上面那个理解了，这个很轻松就解决了，在这里我又遇到一个问题： 此时的listview的item监听不到手势，意思就是我左右滑动listview他没有进行滑动。





  本人对touch众多事件监听拦截等熟悉度不够，因此这里我用到自己写的方法，也许比较麻烦，如果有更好的解决办法，请大家一定要分享哦，再次 thanks for you 了.





  具体解决办法：我们重写listview,对此listview进行手势监听， 我们自定义一个接口来实现 ，具体代码如下：



```

package com.jj.slidingmenu;

import android.content.Context; import android.util.AttributeSet; import android.util.Log; import android.view.GestureDetector; import android.view.MotionEvent; import android.view.GestureDetector.OnGestureListener; import android.view.View; import android.widget.ListView; import android.widget.Toast;

public class MyListView extends ListView implements OnGestureListener {

private GestureDetector gd; // 事件状态 public static final char FLING_CLICK = ; public static final char FLING_LEFT = 1; public static final char FLING_RIGHT = 2; public static char flingState = FLING_CLICK;

private float distanceX;// 水平滑动的距离

private MyListViewFling myListViewFling;

public static boolean isClick = false;// 是否可以点击

public void setMyListViewFling(MyListViewFling myListViewFling) { this.myListViewFling = myListViewFling; }

public float getDistanceX() { return distanceX; }

public char getFlingState() { return flingState; }

private Context context;

public MyListView(Context context) { super(context);

}

public MyListView(Context context, AttributeSet attrs) { super(context, attrs); this.context = context; gd = new GestureDetector(this); }

/**

覆写此方法，以解决ListView滑动被屏蔽问题 */ @Override public boolean dispatchTouchEvent(MotionEvent event) { myListViewFling.doFlingOver(event);// 回调执行完毕. this.gd.onTouchEvent(event);

<span class="keyword">return</span> <span class="keyword">super</span>.dispatchTouchEvent(event);

}

@Override public boolean onTouchEvent(MotionEvent ev) { /*** * 当移动的时候 */ if (ev.getAction() == MotionEvent.ACTION_DOWN) isClick = true; if (ev.getAction() == MotionEvent.ACTION_MOVE) isClick = false; return super.onTouchEvent(ev); }

@Override public boolean onDown(MotionEvent e) { int position = pointToPosition((int) e.getX(), (int) e.getY()); if (position != ListView.INVALID_POSITION) { View child = getChildAt(position - getFirstVisiblePosition()); } return true; }

@Override public void onShowPress(MotionEvent e) {

}

@Override public boolean onSingleTapUp(MotionEvent e) {

<span class="keyword">return</span> <span class="keyword">false</span>;

}

      而在MainActivity.java里面实现该接口,我这么一说，我想有的同学们都明白了，具体实现起来代码有点多，我把代码上传到网上，大家可以下载后 用心看 ，我想大家都能够明白的.（在这里我鄙视一下自己，肯定通过对手势监听拦截实现对listview的左右滑动，但是自己学业不经，再次再说一下，如有好的解决方案，请一定要分享我一下哦.）
    

    
    

      另外有一个问题：当listivew超出一屏的时候， 此时的listview滑动的时候可以上下左右一起滑动,在此没有解决这个问题，如有解决请分享我哦.
    

    
    

      效果图：

      由于篇符较长，先说到这里，其实android 自定义ViewGroup和对view进行切图动画实现滑动菜单SlidingMenu也可以实现.具体参考下一篇文章：
    

    
    

      先写到这里，有不足的地方请指出，
