Question

我正在使用listview我跟随xml跟随listitem

设置的形状

one.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#D5F4FF"/>
    <stroke android:width="1dp" android:color="#979797"/>
    <corners
        android:bottomRightRadius="3dp"
        android:bottomLeftRadius="3dp"
        android:topLeftRadius="3dp"
        android:topRightRadius="3dp"/>
    <padding android:left="5dp" android:top="5dp"
        android:right="5dp" android:bottom="5dp" />
</shape>

two.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#FFA500"/>
    <stroke android:width="1dp" android:color="#979797"/>
    <corners
        android:bottomRightRadius="3dp"
        android:bottomLeftRadius="3dp"
        android:topLeftRadius="3dp"
        android:topRightRadius="3dp"/>
    <padding android:left="5dp" android:top="5dp"
        android:right="5dp" android:bottom="5dp" />
</shape>

现在，默认情况下，我想将 one.xml 设置为我的listitem，当用户点击listitem时，应设置 two.xml 它仍然保持不变，但它不起作用我已尝试使用listselector的{{1}}属性。

Answer 1

在selector xml下方使用 view_selector.xml ：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_pressed="true"><shape  android:shape="rectangle">
            <corners android:bottomLeftRadius="7dp" android:bottomRightRadius="7dp" android:topLeftRadius="7dp" android:topRightRadius="7dp" />

            <solid android:color="@color/view_pressed" />
        </shape></item>

    <item android:state_focused="true"><shape android:shape="rectangle">
            <corners android:bottomLeftRadius="7dp" android:bottomRightRadius="7dp" android:topLeftRadius="7dp" android:topRightRadius="7dp" />

            <solid android:color="@color/view_pressed" />
        </shape></item>

    <item><shape android:shape="rectangle">
            <corners android:bottomLeftRadius="7dp" android:bottomRightRadius="7dp" android:topLeftRadius="7dp" android:topRightRadius="7dp" />

            <solid android:color="@color/view_normal" />
        </shape></item>
</selector>

并在colors.xml中添加颜色：

<color name="view_pressed">#FFA500</color>
<color name="view_normal">#D5F4FF</color>

假设您有一个自定义适配器的示例，该适配器具有布局，您可以在根标记中将其设置为background。举个例子：

<强> custom_adapter_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    android:background="@drawable/view_selector" >

    <TextView 
        style="@style/textviewstyle_Medium"
        android:id="@+id/textview1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="2dp"
        android:lines="2"
        android:text="@string/textview1"/>

      <TextView 
        style="@style/textviewstyle_small"
        android:id="@+id/textview2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="left|center"
        android:padding="2dp"
        android:text="@string/textview2"/>

</LinearLayout>

Answer 2

要使列表选择器起作用，您需要设置ListeView选择模式：

getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);

并覆盖

@Override 
protected void onListItemClick(ListView l, View v, int position, long id) {
    // Make the newly clicked item the currently selected one. 
    getListView().setItemChecked(position, true);
}

注意：确保项目的布局支持选择，或使用android布局文件：android.R.layout.simple_list_item_activated_1

在listitem上点击颜色应该保持不变
