应用程序切换

应用程序切换动效示例

• 第一个APP是一个列表, 第二个APP是一个蜂窝网格.

• 点击第一个APP上的菜单按钮会切换到第二个APP.

• 在切换时，第一个APP会逐渐变透明直至消失, 第二个APP会逐渐增大直至充满屏幕.
  

对应的代码

• 在动画回调函数中,实现了切换过渡动效(缩放和淡入淡出)。

• 当动画结束时, 关闭这个第一个APP。

{
    // Calculate the progress percentage of the animation
    float pro = gui_win_get_aniamtion_progress_percent(win);

    // Adjust the scale of the window based on sine function of the progress percentage
    // This will create a smooth scaling effect as the progress advances
    gui_win_set_scale_rate(win, 1 + sinf(pro * M_PI / 2), 1 + sinf(pro * M_PI / 2));
    // Ensure the scope property is set to 1 (used to indicate visibility)
    gui_win_set_scope(win, 1);
    // Set the opacity of the window's base GUI element, gradually decreasing as the animation progresses
    // This creates a fading effect by setting opacity inversely proportional to the progress percentage
    gui_win_set_opacity(win, (1.0f - pro) * UINT8_MAX);
    // Check if the animation has reached its last frame
    if (gui_win_is_animation_end_frame(win))
    {
        // Shutdown the GUI application
        gui_app_shutdown(get_app_watch_ui());
    }
}

    gui_win_set_animate(win, 2000, 0, app_watch_mune_win_ani_cb, 0);
    gui_win_stop_animation(win);//aniamtion start to play until button click event

• 第二个APP的动画在APP启动时就开始播放。

• 在点击事件中，同时启动了第二个APP。
