我的布局xml代码，

<style name="MyCustomTabLayout" parent="Theme.AppCompat.Light">
    <item name="tabIndicatorHeight">2dp</item>
    <item name="tabPaddingStart">12dp</item>
    <item name="android:layout_width">match_parent</item>
    <item name="tabPaddingEnd">12dp</item>
    <item name="tabBackground">@drawable/background_tab_item</item>
    <item name="tabIndicatorColor">@color/jd_yellow</item>
    <item name="android:layout_gravity">center</item>
    <item name="android:gravity">center</item>
    <item name="tabSelectedTextColor">@color/jd_white</item>
    <item name="tabTextAppearance">@style/MyCustomTabTextAppearance</item>
    <item name="android:textAppearance">@style/MyCustomTabTextAppearance</item>
    <item name="android:background">@drawable/background_tab_item</item>
    <item name="android:textColorSecondary">@color/jd_white</item>
    <item name="colorControlNormal">@color/jd_white</item>
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
    <item name="actionBarTheme">@style/MyApp.ActionBarTheme</item>
    <item name="actionBarWidgetTheme">@style/WidgetStyle</item>
    <item name="colorPrimary">@color/jd_white</item>
    <item name="colorPrimaryDark">@color/jd_white</item>
    <item name="android:textColorPrimary">@color/jd_white</item>
</style>

<style name="WidgetStyle" parent="style/ThemeOverlay.AppCompat.Light">
    <item name="colorControlNormal">@color/jd_white</item>
</style>

<style name="MyApp.ActionBarTheme" parent="@style/ThemeOverlay.AppCompat.ActionBar">
    <!-- change color the arrow or three lines -->
    <item name="colorControlNormal">@color/jd_white</item>
</style>

<!-- Style for the navigation drawer icon -->
<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
    <item name="spinBars">true</item>
    <item name="color">@color/jd_white</item>
</style>

<style name="MyCustomTabTextAppearance" parent="TextAppearance.Design.Tab">
    <item name="android:textColor">@color/jd_white</item>
    <item name="android:textSize">@dimen/tab_layout_text_size</item>
    <item name="android:layout_width">match_parent</item>
    <item name="android:layout_height">match_parent</item>
    <item name="android:layout_gravity">center</item>
    <item name="android:gravity">center</item>
</style>

style.xml中的

  Drawable upArrow = ContextCompat.getDrawable(mContext, R.drawable.abc_ic_ab_back_material);
        upArrow.setColorFilter(ContextCompat.getColor(mContext, R.color.white), PorterDuff.Mode.SRC_ATOP);
        getSupportActionBar().setHomeAsUpIndicator(upArrow);

还尝试将以下内容添加到onCreate（）

section .text
   global _start        

_start:                 

mov eax , 0         ;move value 0 to register eax
mov ebx , 1         ;move value 1 to register ebx
mov ecx , 1         ;move value 1 to register ecx
mov edx , 10        ;move value 10 to register edx

loop:               ;start of loop
mov ebx, ecx        ;move contents of ecx into ebx
add ebx, eax        ;add contents of eax into ebx
mov ecx, eax        ;move contents of eax into ecx
dec edx             ;decrement counter register edx
cmp edx, 0          ;compare counter edx to 0
jne loop            ;jump back into loop unless counter equals 0

没什么可行的，它的颜色仍然是黑色，我做错了什么？请帮忙。

Answer 1

您可以用自己喜欢的任何颜色制作自己的资源，然后将其放在工具栏上。

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeAsUpIndicator(R.drawable.YOUR_ASSET);

Answer 2

尝试将此样式用作工具栏的android：theme：

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    style="@style/MyCustomTabLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:background="?attr/colorPrimary"
    android:elevation="6dp"
    android:minHeight="?attr/actionBarSize"
    android:theme="@style/ToolbarStyle"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

像

'12.abd23yahoo 04/44 231'

Answer 3

经过无数次黑客攻击和奇怪的怪异情况后，这就像魅力一样

 <style name="App"/>
<style name="App.Toolbar">
    <item name="android:id">@id/toolbar</item>
    <item name="android:layout_width">match_parent</item>
    <item name="android:layout_height">?attr/actionBarSize</item>
    <item name="android:background">@android:color/white</item>
    <item name="android:minHeight">?attr/actionBarSize</item>
    <item name="android:theme">@style/ThemeOverlay.AppCompat.Light</item>
    <item name="popupTheme">@style/ThemeOverlay.AppCompat.Dark</item>
</style>
<style name="App.Toolbar.Transparent">
    <item name="android:background">@android:color/transparent</item>
</style>

Answer 4

很简单，这对我有用：

    <android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="56dp"
    android:background="@color/PrimaryColor"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    android:elevation="4dp" />
