私はlistView
を持っています。 custom_listitem1.xmlは、リストに表示されるアイテムに使用されます。次に、アイテムの背景にSelector
ベースのカラーリソース(list_selector_color.xml)を設定します。
custom_listitem1.xml
<TextView xmlns:Android="http://schemas.Android.com/apk/res/Android"
Android:id="@Android:id/text1"
Android:layout_width="fill_parent"
Android:layout_height="wrap_content"
Android:textColor="#000000"
Android:textSize="18sp"
Android:textStyle="bold"
Android:background="@color/list_selector_color"
Android:textAppearance="?android:attr/textAppearanceLarge"
Android:gravity="center_vertical"
Android:paddingLeft="6dip"
Android:minHeight="?android:attr/listPreferredItemHeight"/>
list_selector_color.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:Android="http://schemas.Android.com/apk/res/Android">
<item Android:state_pressed="true"
Android:color="#ffff0000"/> <!-- pressed -->
<item Android:state_focused="true"
Android:color="#ff0000ff"/> <!-- focused -->
<item Android:color="#ff000000"/> <!-- default -->
</selector>
しかし、それは次のエラーを与えています...

私のコードの問題は何ですか?
背景としてカラーセレクターを使用することはできません。代わりにドローアブルセレクターを使用できます。

List_selector_color.xmlはどこに保存しますか? res/colorの場合は、res/drawableに再配置してAndroid:background="@drawable/list_selector_color"
...color.xml
プロジェクトディレクトリに\res\values\color.xml
を作成する必要があります。
サンプルcolor.xml
ファイル
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="background">#1474c0</color>
<color name="row">#ff0000</color>
<color name="translucent_red">#ff0000</color>
</resources>
次に、色の使用方法については、この例を参照し、+++++++サンプルmain.xmlファイルで行を追加してください。
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:Android="http://schemas.Android.com/apk/res/Android"
Android:layout_width="wrap_content"
Android:layout_height="wrap_content"

はい、各textview
を各LinearLayout
に定義すると、機能します。
