如何在材料设计中使用 appCompat 自定义上下文操作栏

MainActivity.java

我已经实施了MultiChoiceModeListener在这个类中，下面是代码：

on listView:

listView.setMultiChoiceModeListener(MainActivity.this);
listView.setChoiceMode(listView.CHOICE_MODE_MULTIPLE_MODAL);


    @Override
    public boolean onActionItemClicked(ActionMode arg0, MenuItem arg1) {
        switch (arg1.getItemId()) {
        case R.id.save:

            // Close CAB
            arg0.finish();
            return true;

        case R.id.saveto:


            // Close CAB
            arg0.finish();
            return true;
        default:
            return false;
        }
    }

    @Override
    public boolean onCreateActionMode(ActionMode arg0, Menu arg1) {
        arg0.getMenuInflater().inflate(R.menu.save_menu, arg1);
        return true;

    }

    @Override
    public void onDestroyActionMode(ActionMode arg0) {
        listadaptor.removeSelection();
    }

    @Override
    public boolean onPrepareActionMode(ActionMode arg0, Menu arg1) {
        return false;
    }

    @Override
    public void onItemCheckedStateChanged(ActionMode arg0, int arg1, long arg2,
            boolean arg3) {

        final int checkedCount = listView.getCheckedItemCount();
        arg0.setTitle(checkedCount + " "+getResources().getString(R.string.selected));
        listadaptor.toggleSelection(arg1);
    }

样式.xml

 <style name="AppTheme.Base" parent="Theme.AppCompat.Light">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/White</item>
        <item name="android:windowNoTitle">true</item>
        <item name="windowActionModeOverlay">true</item>
        <item name="windowActionBar">false</item>
        <item name="actionModeStyle">@style/LStyled.ActionMode</item>
    </style>

    <!-- Application theme. -->
    <style name="AppTheme" parent="AppTheme.Base">
        <!-- All customizations that are NOT specific to a particular API-level can go here. -->
    </style>

    <style name="LStyled.ActionMode" parent="@style/Widget.AppCompat.ActionMode">
        <item name="background">@color/colorPrimary</item>
    </style>

    <style name="ActionBarThemeOverlay" parent="Theme.AppCompat.Light">
        <item name="android:textColorPrimary">#fff</item>
        <item name="colorControlNormal">#fff</item>
        <item name="colorControlHighlight">#3fff</item>
    </style>

    <style name="HeaderBar">
        <item name="android:background">#009688</item>
        <item name="android:textStyle">bold</item>
    </style>

    <style name="ActionBarPopupThemeOverlay" parent="ThemeOverlay.AppCompat.Light">
        <item name="android:textColor">#000</item>
    </style>

下面是我的截图：

您可以看到两个屏幕截图，在第二个屏幕截图中，动作模式背景是白色，文本颜色也是白色。我想将其更改为顶部的第一个屏幕截图颜色。

您可以更改ActionMode通过属性背景actionModeStyle:

<style name="AppTheme.Base" parent="Theme.AppCompat.Light">
    ....
    ....
    <item name="actionModeStyle">@style/LStyled.ActionMode</item>
</style>

<style name="LStyled.ActionMode" parent="@style/Widget.AppCompat.ActionMode">
    <item name="background">@color/color_action_mode_bg</item>
</style>

您当然需要定义一个名为color_action_mode_bg:

<color name="color_action_mode_bg">#009688</color>

您还可以更改其他内容。例子：

<item name="titleTextStyle">...</item>
<item name="subtitleTextStyle">...</item>
<item name="height">...</item>

更改文本颜色SAVE and SAVETO，添加以下内容AppTheme.Base:

<item name="actionMenuTextColor">@color/color_action_mode_text</item>
