圆角listview

1.重写listview

package com.example.cornerlistviewdemo;import android.content.Context;import android.util.AttributeSet;import android.view.MotionEvent;import android.view.View;import android.view.ViewGroup;import android.widget.AdapterView;import android.widget.ListAdapter;import android.widget.ListView;/** * 自定义圆角ListView * @author DingMaolin * */public class CornerListView extends ListView {    public CornerListView(Context context) {        super(context);    }    public CornerListView(Context context, AttributeSet attrs, int defStyle) {        super(context, attrs, defStyle);    }    public CornerListView(Context context, AttributeSet attrs) {        super(context, attrs);    }    @Override    public boolean onInterceptTouchEvent(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                            setSelector(R.drawable.listview_corner_round);                        }else{                         // 第一项                            setSelector(R.drawable.listview_corner_round_top);                        }                }else if(itemnum==(getAdapter().getCount()-1)){                 // 最后一项                        setSelector(R.drawable.listview_corner_round_bottom);                }else{                       // 中间项                    setSelector(R.drawable.listview_corner_middle);                }                }                break;        case MotionEvent.ACTION_UP:                break;        }                return super.onInterceptTouchEvent(ev);    }        /**  * 设置不滚动  */ @Override public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {  int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,    MeasureSpec.AT_MOST);  super.onMeasure(widthMeasureSpec, expandSpec); }        /*** * 动态设置listview的高度 *  * @param listView */public void setListViewHeightBasedOnChildren(ListView listView) {ListAdapter listAdapter = listView.getAdapter();if (listAdapter == null) {return;}int totalHeight = 0;for (int i = 0; i < listAdapter.getCount(); i++) {View listItem = listAdapter.getView(i, null, listView);listItem.measure(0, 0);totalHeight += listItem.getMeasuredHeight();}ViewGroup.LayoutParams params = listView.getLayoutParams();params.height = totalHeight+ (listView.getDividerHeight() * (listAdapter.getCount() - 1));// params.height += 5;// if without this statement,the listview will be// a// little short// listView.getDividerHeight()获取子项间分隔符占用的高度// params.height最后得到整个ListView完整显示需要的高度listView.setLayoutParams(params);}}

2.定义圆角drawable

不多说了，直接上源码吧
