获取状态栏高度

//获取status_bar_height资源的ID
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
    //根据资源ID获取响应的尺寸值
    int statusBarHeight = getResources().getDimensionPixelSize(resourceId);
    SPUtils.putInt(Constant.STATUSBAR_HEIGHT,statusBarHeight);
}

动态设置控件高度 

int statusBarHeight = SPUtils.getInt(Constant.STATUSBAR_HEIGHT, 0);
if (statusBarHeight > 0) {
    LinearLayout.LayoutParams sp_params = new LinearLayout.LayoutParams(
            RelativeLayout.LayoutParams.MATCH_PARENT,
            RelativeLayout.LayoutParams.WRAP_CONTENT);
    sp_params.height = statusBarHeight;
    mvView.setLayoutParams(sp_params);
}

务必保持一致 ( LinearLayout. LinearLayout.LayoutParams 与需要设置的控件父控件)

LinearLayout.LayoutParams

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <View
        android:id="@+id/mv_view"
        android:layout_width="match_parent"
        android:layout_height="@dimen/statusbar_height"
        android:background="@color/colorTheme"
            android:visibility="visible" />
    </LinearLayout>
