如果你想通过编程方式改变状态栏的颜色(前提是设备有Android 5.0)。 这是一个简单的方法来改变statusBarColor从任何活动 和非常简单的方法，当不同的片段有不同的状态栏颜色。

 /**
 * @param colorId id of color
 * @param isStatusBarFontDark Light or Dark color
 */
fun updateStatusBarColor(@ColorRes colorId: Int, isStatusBarFontDark: Boolean = true) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        val window = window
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
        window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
        window.statusBarColor = ContextCompat.getColor(this, colorId)
        setSystemBarTheme(isStatusBarFontDark)
    }
}

/** Changes the System Bar Theme.  */
@RequiresApi(api = Build.VERSION_CODES.M)
private fun setSystemBarTheme(isStatusBarFontDark: Boolean) {
    // Fetch the current flags.
    val lFlags = window.decorView.systemUiVisibility
    // Update the SystemUiVisibility depending on whether we want a Light or Dark theme.
    window.decorView.systemUiVisibility = if (isStatusBarFontDark) lFlags and View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR.inv() else lFlags or View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR
}

这是一个非常简单的方法来做到这一点，没有任何库: 如果操作系统版本不支持-在kitkat -所以什么都不会发生。 我做这些步骤:

在我的xml中，我添加到顶部这个视图:

<视图 android: id =“@ + id / statusBarBackground” android: layout_width = " match_parent " android: layout_height = " wrap_content " / >

然后我做了这个方法:

 public void setStatusBarColor(View statusBar,int color){
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
           Window w = getWindow();
           w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
           //status bar height
           int actionBarHeight = getActionBarHeight();
           int statusBarHeight = getStatusBarHeight();
           //action bar height
           statusBar.getLayoutParams().height = actionBarHeight + statusBarHeight;
           statusBar.setBackgroundColor(color);
     }
}

你也需要这两个方法来获得动作栏和状态栏的高度:

public int getActionBarHeight() {
    int actionBarHeight = 0;
    TypedValue tv = new TypedValue();
    if (getTheme().resolveAttribute(android.R.attr.actionBarSize, tv, true))
    {
       actionBarHeight = TypedValue.complexToDimensionPixelSize(tv.data,getResources().getDisplayMetrics());
    }
    return actionBarHeight;
}

public int getStatusBarHeight() {
    int result = 0;
    int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
    if (resourceId > 0) {
        result = getResources().getDimensionPixelSize(resourceId);
    }
    return result;
}

然后你唯一需要做的就是这一行来设置状态栏的颜色:

setStatusBarColor(findViewById(R.id.statusBarBackground),getResources().getColor(android.R.color.white));

这就是我在奇巧(KitKat)的做法，而且效果不错。

public static void setTaskBarColored(Activity context) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT)
        {
            Window w = context.getWindow();
            w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            //status bar height
            int statusBarHeight = Utilities.getStatusBarHeight(context);

            View view = new View(context);
            view.setLayoutParams(new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
            view.getLayoutParams().height = statusBarHeight;
            ((ViewGroup) w.getDecorView()).addView(view);
            view.setBackgroundColor(context.getResources().getColor(R.color.colorPrimaryTaskBar));
        }
    }

你可以使用这段简单的代码:

Kotlin中的一行代码:

window.statusBarColor = ContextCompat.getColor(this, R.color.colorName)

原始答案与Java和手动版本检查:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    getWindow().setStatusBarColor(getResources().getColor(R.color.colorAccentDark_light, this.getTheme()));
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    getWindow().setStatusBarColor(getResources().getColor(R.color.colorAccentDark_light));
}

要改变上面棒棒糖的颜色，只需将其添加到您的styles.xml中

<item name="android:statusBarColor">@color/statusBarColor</item>

但是请记住，如果你想让状态栏有一个浅色，也可以添加这一行

<item name="android:windowLightStatusBar">true</item>

此解决方案仅适用于API >= 23。 在API级别30中，setSystemUiVisibility()已弃用。因此你应该像下面这样使用WindowInsetsControllerCompat

fun changeColorStatusBar(color: Int = R.color.white) {
        val window: Window = window
        val decorView = window.decorView
        val wic = WindowInsetsControllerCompat(window, decorView)
        wic.isAppearanceLightStatusBars = true
        // And then you can set any background color to the status bar.
        window.statusBarColor = ContextCompat.getColor(this, color)
    }
