如何改变一个ListView里面TextView的文本颜色被点击列表项的时候？ [英] How to change TextView text color inside a ListView when list item is clicked?

问题描述

我试图改变一个ListView项内一个TextView的文本颜色。

I am trying to change text color of a TextView inside a listview item.

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                view.setSelected(true);

               ViewGroup selectedGroup = (ViewGroup)view;

                ((TextView)selectedGroup.getChildAt(4)).setTextColor(Color.parseColor("#336699"));
                String mID =String.valueOf(((TextView) selectedGroup.getChildAt(4)).getText());
            }
        });

但没有任何反应，我可以得到的TextView的文本价值，虽然。什么可能是错误的这code？

But nothing happens, I can get text value of the textview, though. What might be wrong in this code?

这是，顺便说一句，我的ListView的布局。

This is, by the way, my listView layout.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="4dp">
    <TextView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:textColor="#336699"
        android:id="@+id/questionTitle"
        android:textSize="18sp"/>
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="#444444"
        android:id="@+id/questionDate"
        android:textSize="12sp"/>
    <TextView android:layout_height="0dp" android:layout_width="0dp" android:visibility="invisible"
        android:id="@+id/questionContent" android:value=""/>
    <TextView android:layout_height="0dp" android:layout_width="0dp" android:visibility="invisible"
        android:id="@+id/questionSenderContact" android:value=""/>
    <TextView android:layout_height="0dp" android:layout_width="0dp" android:visibility="invisible"
              android:id="@+id/messageID" android:value=""/>

</LinearLayout>

编辑：我得到错误的TextView。它的指数是不是4，但0对不起，缺乏所引起重视的问题。

I was getting wrong textview. Index of it was not 4, but 0. Sorry for a question caused by lack of attention.

推荐答案

试试这个code：

public View row;

your_list.setOnItemClickListener(new OnItemClickListener() {

public void onItemClick(AdapterView<?> a, View v,
                    int position, long id) {

if (row != null) {
    row.setBackgroundResource(R.color.orange);
}
row = v;
v.setBackgroundResource(R.color.transparent_green);
)};
