Simple Line

{
    /*Create an array for the points of the line*/
    static lv_point_t line_points[] = { {5, 5}, {70, 70}, {120, 10}, {180, 60}, {240,10} };  // 5个点坐标值
 

    /*Create style*/
    static lv_style_t style_line;
    lv_style_init(&style_line);
    lv_style_set_line_width(&style_line, 8);  // 设置线宽
    lv_style_set_line_color(&style_line, lv_palette_main(LV_PALETTE_BLUE));//设置线条颜色为蓝色
    lv_style_set_line_rounded(&style_line, true); // 使能线条圆角功能
    /*Create a line and apply the new style*/
    lv_obj_t* line1;
    line1 = lv_line_create(lv_scr_act());  // 创建线条对象
    lv_line_set_points(line1, line_points, 5); // 设置线条数据点数
    lv_obj_add_style(line1, &style_line, 0); // 线条添加style
    lv_obj_center(line1);  // 居中显示
