设置顶部系统栏颜色和actionbar颜色相同

在activity中调用以下方法：

    /**
     * Apply KitKat specific translucency.
     */
    private void applyKitKatTranslucency() {

        // KitKat translucent navigation/status bar.
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            setTranslucentStatus(true);
            SystemBarTintManager mTintManager = new SystemBarTintManager(this);
            mTintManager.setStatusBarTintEnabled(true);
            mTintManager.setNavigationBarTintEnabled(true);
            mTintManager.setTintColor(getResources().getColor(R.color.actionbar_background));

        }

    }

    @TargetApi(19)
    private void setTranslucentStatus(boolean on) {
        Window win = getWindow();
        WindowManager.LayoutParams winParams = win.getAttributes();
        final int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
        if (on) {
            winParams.flags |= bits;
        } else {
            winParams.flags &= ~bits;
        }
        win.setAttributes(winParams);
    }
