我想在我的应用程序中应用不同的主题。我想改变导航栏和浮动动作按钮的颜色。

现在我可以改变导航栏的颜色,但浮动动作按钮的颜色不会改变。当主题改变时,如何动态改变fab的颜色?

风格:

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="colorAccent_500">@color/accent_500</item>
        <item name="colorAccent_700">@color/accent_700</item>

        <item name="windowActionBarOverlay">false</item>

        <item name="windowActionBar">false</item>

        <item name="windowNoTitle">true</item>
        <item name="android:windowBackground">@color/background_material_light</item>
    </style>
    <style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
    <style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />


    <style name="BlueTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">#3F51B5</item>
        <item name="colorPrimaryDark">#303F9F</item>
        <item name="colorAccent">#03A9F4</item>

        <item name="windowActionBarOverlay">false</item>

        <item name="windowActionBar">false</item>

        <item name="windowNoTitle">true</item>
        <item name="android:windowBackground">@color/background_material_light</item>
    </style>


    <style name="AppTheme.Solarized">
        <item name="colorPrimary">@color/orange300</item>
        <item name="colorPrimaryDark">@color/orange500</item>
        <item name="colorAccent">@color/solarizedOrange</item>
        <item name="android:textColorPrimary">@color/solarizedBase01</item>
        <item name="android:textColorSecondary">@color/solarizedBase1</item>
    </style>


</resources>

Fab:

    <?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/main_fab"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:layout_gravity="bottom|end">

    <View
        android:id="@+id/myfab_shadow"
        android:layout_width="72dp"
        android:layout_height="72dp"
        android:layout_gravity="center"
        android:background="@drawable/fab_shadow"
        android:focusable="false" />

    <ImageButton
        android:id="@+id/imgbtn_fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:background="@drawable/fab_selector"
        android:cropToPadding="true"
        android:padding="10dp"
        android:src="@drawable/ic_add_white_36dp"
        android:stateListAnimator="@animator/fab_elevation_selector" />

</FrameLayout>

Fab选择器:

  <?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="oval">
            <solid android:color="@color/colorAccent" />
        </shape>
    </item>

    <item android:state_focused="true">
        <shape android:shape="oval">
            <solid android:color="@color/accent_700" />
        </shape>
    </item>

    <item>
        <shape android:shape="oval">
            <solid android:color="@color/accent_500" />
        </shape>
    </item>

</selector>

谢谢..

浮动操作按钮根据您的 colorAccent

进行着色
<style name="AppTheme" parent="Base.Theme.AppCompat.Light">
    <item name="colorAccent">@color/accent</item>
</style>

或者来自代码:

fab.setBackgroundTintList(getResources().getColorStateList(R.color.blue));

或者来自XML:

更改 app:backgroundTint

的属性

但似乎您使用 ImageButton 而不是 FloatingActionButton ,您应该使用:

 <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        android:layout_margin="@dimen/fab_margin" />

在依赖项中添加:

dependencies {
    compile 'com.android.support:design:23.1.1'
}

谢谢你的回答。但我刚刚换过fab选择器。

<item android:state_pressed="true">
    <shape android:shape="oval">
        <solid android:color="?attr/colorAccent" />
    </shape>
</item>

<item android:state_focused="true">
    <shape android:shape="oval">
        <solid android:color="?attr/colorAccent" />

    </shape>
</item>

<item>
    <shape android:shape="oval">
        <solid android:color="?attr/colorAccent" />
    </shape>
</item>

这有效..

请使用带有浮动按钮的材料形状主题,它现在非常容易,无需自定义
