Question

我设置了一个项目并希望使用Material设计。由于应用程序应与低于21的API兼容，我使用appcompat。不幸的是我无法改变状态栏的颜色。

我已阅读：How to change the status bar color in android 并且：https://chris.banes.me/2014/10/17/appcompat-v21/

我的布局是android.support.v4.widget.DrawerLayout。 ActionBar的颜色会更改，但不会更改状态栏的颜色。我的xml：

<resources>

<!--
    Base application theme, dependent on API level. This theme is replaced
    by AppBaseTheme from res/values-vXX/styles.xml on newer devices.


-->
<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <!--
        Theme customizations available in newer API levels can go in
        res/values-vXX/styles.xml, while customizations related to
        backward-compatibility can go here.


    -->
</style>

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">

    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
    <!-- colorPrimary is used for the default action bar background -->
    <item name="colorPrimary">@color/green500</item>
    <!-- colorPrimaryDark is used for the status bar -->
    <item name="colorPrimaryDark">@color/green900</item>
</style>

实际上，应用无法使用低于API 19的状态栏颜色更改。

我写了一个演示。当API级别高于或等于API 19时，它工作正常。你的风格设置是对的。但是，如果您希望该应用程序与API 19兼容。你应该添加一些代码。

class Utils {
private static int getStatusBarHeight(Context context) {
    Context appContext = context.getApplicationContext();
    int result = 0;
    int resourceId = appContext.getResources().getIdentifier("status_bar_height", "dimen", "android");
    if (resourceId > 0) {
        result = appContext.getResources().getDimensionPixelSize(resourceId);
    }
    return result;
}

static void setStatusbarColor(Activity activity, View view) {
    Window w = activity.getWindow();
    if (Build.VERSION.SDK_INT == Build.VERSION_CODES.KITKAT) {
        w.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        w.addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
        int statusBarHeight = getStatusBarHeight(activity);
        view.setLayoutParams(new CoordinatorLayout.LayoutParams(CoordinatorLayout.LayoutParams.MATCH_PARENT
                , view.getLayoutParams().height + statusBarHeight));
        view.setPadding(0, statusBarHeight, 0, 0);
    }
}

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    Utils.setStatusbarColor(this, toolbar);
    setSupportActionBar(toolbar);
}
