今天在Android群里面有人再求圆角ListView的实现方式，正好自己以前实现过。因此就共享了

       现在将其实现方式写在博客中共他人学习。给出实现方式之前顺带加点自己的想法，感觉上android

       中方形的ListView还是太“硬性”，没有圆角的有亲和力。连Apple也为了“圆角”这个设计去申请专利

       看来圆角确实比较适合现在人们的喜好吧。

              照老规矩先上两张效果图吧：

       第一张：

      第二张：

          该方式主要就是需要重新去实现自己的ListView代码如下：

package com.kiritor.corner_listview;   import android.content.Context; import android.util.AttributeSet; import android.view.MotionEvent; import android.widget.AdapterView; import android.widget.ListView;  /***  * 自定义listview  *   * @author Kiritor  *   */ public class MyListView extends ListView { 	public MyListView(Context context) { 		super(context); 	}  	public MyListView(Context context, AttributeSet attrs) { 		super(context, attrs); 	}  	/**** 	 * 拦截触摸事件 	 */ 	@Override 	public boolean onTouchEvent(MotionEvent ev) { 		switch (ev.getAction()) { 		case MotionEvent.ACTION_DOWN: 			int x = (int) ev.getX(); 			int y = (int) ev.getY(); 			int itemnum = pointToPosition(x, y); 			if (itemnum == AdapterView.INVALID_POSITION) 				break; 			else { 				if (itemnum == 0) { 					if (itemnum == (getAdapter().getCount() - 1)) { 						// 只有一项数据，设置背景设置为圆角的 						setSelector(R.drawable.list_round); 					} else { 						// 第一项，设置为上面为圆角的 						setSelector(R.drawable.list_top_round); 					} 				} else if (itemnum == (getAdapter().getCount() - 1)) 					// 最后一项，设置为下面为圆角的 					setSelector(R.drawable.list_bottom_round); 				else { 					// 中间项，不用设置为圆角 					setSelector(R.drawable.list_center_round); 				} 			} 			break; 		case MotionEvent.ACTION_UP: 			break; 		} 		return super.onTouchEvent(ev); 	} }

               差不多也就是这样了，还有相关资源文件

                       

                这里就不一一给出了
