Question

我的操作栏中有一个导航列表，背景为深色。然而，弹出菜单有白色背景。

所以我想要实现的是，操作栏内的项目文本颜色是白色，而菜单弹出的项目文本颜色是黑色。

这是我到目前为止的两个例子：

这应该是这样的：

有谁知道解决方案？

这是我的列表导航代码：

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
        android.R.layout.simple_dropdown_item_1line, new String[] { "Item 1", "Item 2" });

getSupportActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);
getSupportActionBar().setListNavigationCallbacks(adapter,
        new ActionBar.OnNavigationListener() {
            @Override
            public boolean onNavigationItemSelected(int itemPosition, long itemId) {
                return true;
            }
        });

getSupportActionBar().setSelectedNavigationItem(0)

这些是我使用的样式集合。

<style name="CustomTheme" parent="@style/Theme.customized">
      <item name="actionBarStyle">@style/Widget.Styled.ActionBar</item>
      <item name="android:actionBarStyle">@style/Widget.Styled.ActionBar</item>
      <item name="actionDropDownStyle">@style/CustomSherlockDropDownNav</item>
      <item name="android:actionDropDownStyle">@style/CustomSherlockDropDownNav</item>

      <item name="android:popupBackground">@drawable/menu_dropdown_panel_customtab</item>
      <item name="android:background">@drawable/spinner_background_ab_customtab</item>
</style>

然而没有什么不起作用。

Answer 1

问题是您对微调器项和微调器下拉项使用相同的资源android.R.layout.simple_dropdown_item_1line。

改为使用R.layout.sherlock_spinner_item和R.layout.sherlock_spinner_dropdown_item。

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
         R.layout.sherlock_spinner_item, new String[] { "Item 1", "Item 2" });
adapter.setDropDownViewResource(R.layout.sherlock_spinner_dropdown_item);

这样，Widget.Sherlock.TextView.SpinnerItem等样式就可以了。

Answer 2

您只需创建自定义xml即可实现此目标，该xml将成为您的列表项。像这样创建你的xml：的 custom_list_item.xml

<?xml version="1.0" encoding="utf-8"?> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/text1" style="?android:attr/spinnerDropDownItemStyle" android:singleLine="true" android:textSize="18sp" android:textColor="@color/holo_dark_red" android:paddingRight="110dip" android:layout_width="match_parent" android:layout_height="?attr/dropdownListPreferredItemHeight" android:textIsSelectable="false" android:ellipsize="marquee" />

并像这样使用它：

adapter.setDropDownViewResource(R.layout.custom_list_item);

应该这样做（至少它在我的应用程序中工作）。

Answer 3

<style name="Theme.WhyCheck" parent="@style/Theme.AppCompat.Light">
<item name="android:spinnerItemStyle">@style/DropDownNav.Item.Inverse</item>
</style>

<style name="DropDownNav.Item.Inverse" parent="@style/Widget.AppCompat.DropDownItem.Spinner">
    <item name="android:textAppearance">@style/ActionBar.TitleText</item>
</style>

<style name="ActionBar.TitleText" parent="@style/TextAppearance.AppCompat.Widget.ActionBar.Title">
    <item name="android:fontFamily">sans-serif-light</item>
    <item name="android:textColor">@color/white</item>
</style>

应该是这样的。不知道为什么使用微调器“Item”Style @@

         @Override
    public View getView(int position, View convertView, ViewGroup parent) {


        // Inflating the layout for the custom Spinner
        LayoutInflater inflater = getLayoutInflater();
        View layout = inflater.inflate(R.layout.custom, null);

        // Declaring and Typecasting the textview in the inflated layout
        TextView tvLanguage = (TextView) layout
        .findViewById(R.id.tvLanguage);

        // Setting the text using the array
        tvLanguage.setText(obj[position]);

        //tvLanguage.setTextColor(Color.BLACK);
        tvLanguage.setTextSize(14f);




        return layout;

    }
    @Override
    public View getDropDownView(int position, View convertView,
            ViewGroup parent) {
        // TODO Auto-generated method stub


        LayoutInflater inflater = getLayoutInflater();
        View layout = inflater.inflate(R.layout.customdropdown, null);

        // Declaring and Typecasting the textview in the inflated layout
        TextView tvLanguage = (TextView) layout
        .findViewById(R.id.tvLanguage);

        // Setting the text using the array
        tvLanguage.setText(obj[position]);

        //tvLanguage.setTextColor(Color.BLACK);
        tvLanguage.setTextSize(14f);



        return layout;
    }

}
