点击ListView的时候，条目的背景颜色等等都会影响视觉效果，现在对ListView优化，创建一个自定义的ListView使用的时候直接使用自定义的ListView。
package com.ldw.market.view; import com.ldw.market.R; import com.ldw.market.utils.UiUtils; import android.content.Context; import android.util.AttributeSet; import android.widget.ListView; /* * 自定义ListView的方法，初始化ListView的时候会初始化这些方法 */ public class BaseListView extends ListView { public BaseListView(Context context) { super(context); init(); } public BaseListView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); init(); } public BaseListView(Context context, AttributeSet attrs) { super(context, attrs); init(); } private void init() { // setSelector 点击显示的颜色 // setCacheColorHint 拖拽的颜色 // setDivider 每个条目的间隔 的分割线 this.setSelector(R.drawable.nothing); // 什么都没有 this.setCacheColorHint(R.drawable.nothing); this.setDivider(UiUtils.getDrawalbe(R.drawable.nothing)); } } UiUtils.java public static Drawable getDrawalbe(int id) { return getResource().getDrawable(id); }HomeFragment.java使用自定义的控件
