在android材质设计中，如何根据图像颜色改变工具栏和状态栏的颜色？

Question

我开始学习Android材质设计。我学到了Lollipop版本的一些新功能。今天我尝试根据图像的颜色改变工具栏和状态栏的颜色。谁能指导我或提供任何链接如何做这一点？

styles.xml：

   < style name="MyMaterialTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
            <item name="windowNoTitle">true</item>
            <item name="windowActionBar">false</item>
            <item name="colorPrimary">@color/colorPrimary</item>
            <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
            <item name="colorAccent">@color/colorAccent</item>
        </style>

Answer 1

在style.xml中创建自定义主题。然后在menifest中为每个活动设置每个主题：

style.xml：

<style name="Activity1Theme" parent="MyMaterialTheme.Base">
     <item name="colorPrimary">@color/blue</item>
     <item name="colorPrimaryDark">@color/darkblue</item>
</style>

<style name="Activity2Theme" parent="MyMaterialTheme.Base">
     <item name="colorPrimary">@color/green</item>
     <item name="colorPrimaryDark">@color/darkgreen</item>
</style>

梅尼夫斯特：

<activity
        android:name=".Activity1Theme"
        android:theme="@style/Activity1Theme"></activity>
<activity
        android:name=".Activity2Theme"
        android:theme="@style/Activity2Theme"></activity>

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

// create ContextThemeWrapper from the original Activity Context with the custom theme
final Context contextThemeWrapper = new ContextThemeWrapper(getActivity(), R.style.yourCustomTheme);

// clone the inflater using the ContextThemeWrapper
LayoutInflater localInflater = inflater.cloneInContext(contextThemeWrapper);

// inflate the layout using the cloned inflater, not default inflater
return localInflater.inflate(R.layout.yourLayout, container, false);
}
