ListView的Item选中改变TextView字体颜色

字体颜色只是在按下那一瞬间改变，松手后立刻恢复

1.在res/color文件下创建item_text_selector.xml文件

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="@color/colorAccent" android:state_pressed="true"></item>
<item android:color="@color/colorPrimaryDark" android:state_pressed="false"></item>
</selector>

2.在TextView中引用即可

android:textColor="@drawable/item_text_selector"

字体颜色按下后就一直为改变的颜色，松手后不会恢复，直到下一个Item选中后才恢复

ListView的Item选中改变TextView字体颜色

处理思想：在适配器里写好字体变化的相关逻辑，然后在外部事件监听中改变某个值，通知字体改变。

1.将item_text_selector.xml中的state_pressed改为state_selected

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/colorleft" android:state_selected="true"></item>
    <item android:color="@color/colorTextt" android:state_selected="false"></item>
</selector>

2.在TextView中引用

3.然后在自定义的适配器代码中

//当前Item被点击的位置
private int currentItem;
public void setCurrentItem(int currentItem) {
    this.currentItem = currentItem;
}

然后在getView()方法中

//设置文本内容
viewHolder.videotwo_list_time.setText("课程时长："+i1+"分钟");

if (currentItem == i) {
    //如果被点击，设置当前TextView被选中
    viewHolder.videotwo_list_title.setSelected(true);
    viewHolder.videotwo_list_time.setSelected(true);
} else {
    //如果没有被点击，设置当前TextView未被选中
    viewHolder.videotwo_list_title.setSelected(false);
    viewHolder.videotwo_list_time.setSelected(false);
}

4.最后在Activity中编写ListView的Item点击事件

mVideotwoLisview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
        //改变选中状态
        adpater.setCurrentItem(i);
        //通知ListView改变状态
        adpater.notifyDataSetChanged();
    }
});

改变背景颜色也是类似

if (currentItem == i) {
            //如果被点击，设置当前TextView被选中
            viewHolder.videotwo_list_title.setSelected(true);
            viewHolder.videotwo_list_time.setSelected(true);
            viewHolder.videotwo_carryout.setSelected(true);

//            viewHolder.videotwo_listview.setBackground(R.drawable.baidihongbian);
            viewHolder.videotwo_listview.setBackgroundResource(R.drawable.baidihongbian);
        } else {
            //如果没有被点击，设置当前TextView未被选中
            viewHolder.videotwo_list_title.setSelected(false);
            viewHolder.videotwo_list_time.setSelected(false);
            viewHolder.videotwo_carryout.setSelected(false);

//            viewHolder.videotwo_listview.setBackgroundColor();
            viewHolder.videotwo_listview.setBackgroundResource(R.color.gray_f4);
        }
