Java 如何在android中更改Listview项目颜色和textcolor

在我的应用程序中，我创建了一个Listview。单击该行时，我希望将Listview行的颜色更改为浅灰色，将textcolor更改为蓝色

为此，我尝试了下面的代码，但只有行背景颜色在改变，而不是文本颜色

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

                for (int j = 0; j < parent.getChildCount(); j++) {

                    parent.getChildAt(j).setBackgroundColor(Color.TRANSPARENT);
                    view.setBackgroundColor(Color.LTGRAY);

                    rowText = (TextView) findViewById(R.id.rowitem);
                    rowText.setTextColor(Color.BLUE);
                }


   }
    });
}

mainListView.setOnItemClickListener（新的AdapterView.OnItemClickListener（）{
@凌驾
public void onItemClick（AdapterView父对象、视图、整型位置、长id）{
对于（int j=0；j

首先创建一个可绘制的选择器，如下所示：

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@android:color/red"
          android:state_pressed="true" />
    <item android:drawable="@android:color/white" />
</selector>

改变

 rowText = (TextView) findViewById(R.id.rowitem);

到

因为您应该在膨胀视图中找到textview，而不是单独找到它。

首先在ListView中启用android:ListSelector属性

ListView android:id="@+id/android:list" android:layout_width="fill_parent"
    android:layout_height="wrap_content" 
    android:layout_below="@+id/Tablayoutdesign"
    android:cacheColorHint="#000000"
    android:dividerHeight="1dip"
    android:layout_marginTop="63dip"
    android:layout_marginBottom="40dip"

    />

感谢创建选择器（listselector.xml）

而不是使用colors.xml

<resources>
<drawable name="focused">#ff5500</drawable>
<drawable name="selected">#FF00FF</drawable>
</resources>

#ff5500
#FF00FF

还有一些Java魔法： listview.setSelector（R.drawable.listselector）

未按时列表查看背景

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">

            <corners android:radius="2dp" />

    <item
        android:bottom="2dp"
        android:left="0dp"
        android:right="0dp"
        android:top="0dp">
        <shape android:shape="rectangle">

            <corners android:radius="2dp" />

    <item

        android:right="0dp"
        android:top="0dp">
        <shape android:shape="rectangle">
            <solid android:color="#FFF" />
            <corners android:radius="2dp" />
        </shape>
    </item>
</layer-list>

列表视图选择器

<?xml version="1.0" encoding="utf-8"?>

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/card_state_pressed" android:state_pressed="true" />
    <item android:drawable="@drawable/card_background" />
</selector>

当我点击假设第一行，然后第一行背景和文本颜色必须改变，当我点击第二行，然后第二行背景和文本颜色必须改变，并且第一行背景和文本颜色必须位于前面的colorsOk，然后用你刚才告诉我的内容更新你的问题，同时我也在更新答案

<?xml version="1.0" encoding="utf-8"?>

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/card_state_pressed" android:state_pressed="true" />
    <item android:drawable="@drawable/card_background" />
</selector>
