Introduces a new `AutoScrollingText` composable that provides a marquee effect for text that overflows its container. This component is designed for efficiency: - It uses `SubcomposeLayout` to measure the text and only applies the scrolling animation if the content is wider than the available space. - The scrolling is implemented using the optimized `basicMarquee` modifier from Jetpack Compose. - A horizontal gradient is used with `drawWithContent` to create a smooth fade-out effect on the edges, ensuring the text blends seamlessly with its background. The `AutoScrollingText` component has been integrated into the `PlayerSongInfo` composable to handle long song titles and artist names in the player UI, replacing the previous `TextOverflow.Ellipsis` truncation.
This commit corrects the implementation of the `AutoScrollingText` composable. The previous version had an issue where the gradient colors for the fade-out effect were in the wrong order, causing the text to be incorrectly masked and thus invisible. The `Brush.horizontalGradient` color list has been corrected to ensure the left edge fades in (transparent to background) and the right edge fades out (background to transparent), restoring the intended functionality. The original feature implementation, which provides an efficient, auto-scrolling marquee for overflowing text using `SubcomposeLayout` and `basicMarquee`, remains the same.
This commit provides the final fix for the `AutoScrollingText` composable, addressing two key issues from previous implementations: 1. **Static Fade Effect:** The composable has been restructured to apply the fade-out gradient to a static parent `Box` container. This ensures the fade effect remains fixed at the edges of the container and does not scroll with the text content, which was the primary visual bug. 2. **Marquee Spacing:** The `spacing` parameter of the `basicMarquee` modifier has been increased to `MarqueeSpacing(gradientWidth)`. This adds a proper gap between the repeated text instances, creating a smoother and more visually pleasing infinite loop. This implementation correctly separates the static UI elements from the scrolling content, resulting in the intended and correct behavior. The component now reliably provides a marquee effect only when text overflows, with a seamless, static fade at the edges.
This commit introduces a sophisticated, reusable `AutoScrollingText` composable that provides a polished marquee effect for overflowing text. This final version includes several key refinements based on detailed feedback: 1. **Animated Fade-in:** The fade effect at the edges is now animated. It is initially fully transparent, ensuring the text is completely visible when stationary. 2. **Synchronized Animations:** A `LaunchedEffect` is used to synchronize the fade-in animation with the `initialDelayMillis` of the `basicMarquee` modifier. This creates a seamless experience where the fade appears just as the text begins to scroll. 3. **Corrected Layout Structure:** The fade effect is applied to a static parent `Box`, while the `Text` composable scrolls within it. This ensures the fade remains fixed at the edges and does not move with the text. 4. **Adjusted Spacing:** The spacing between text repetitions in the marquee has been fine-tuned to provide a smoother visual loop. This component has been integrated into the `PlayerSongInfo` composable to handle long song titles and artist names, replacing the previous `TextOverflow.Ellipsis` truncation with a more elegant and user-friendly solution.
This commit introduces a sophisticated, reusable `AutoScrollingText` composable that provides a polished marquee effect for overflowing text. This final version includes several key refinements based on detailed feedback: 1. **Animated Fade-in:** The fade effect at the edges is now animated by animating the alpha of the gradient draw calls. It is initially fully transparent (alpha=0), ensuring the text is completely visible when stationary. 2. **Synchronized Animations:** A `LaunchedEffect` is used to synchronize the fade-in animation with the `initialDelayMillis` of the `basicMarquee` modifier. This creates a seamless experience where the fade appears just as the text begins to scroll. 3. **Corrected Layout Structure:** The fade effect is applied to a static parent `Box`, while the `Text` composable scrolls within it. This ensures the fade remains fixed at the edges and does not move with the text. 4. **Adjusted Spacing:** The spacing between text repetitions in the marquee has been fine-tuned to `gradientWidth + 6.dp` to provide a smoother visual loop as requested. This component has been integrated into the `PlayerSongInfo` composable to handle long song titles and artist names, replacing the previous `TextOverflow.Ellipsis` truncation with a more elegant and user-friendly solution.
This commit introduces the final, correct implementation of the `AutoScrollingText` composable, addressing specific, nuanced feedback on the fade effect. This version includes the following critical refinements: 1. **Isolated Left-Side Fade Animation:** The fade-in animation is now applied *only* to the left-side gradient. The right-side gradient is rendered statically from the start to handle the initial text overflow. This ensures the text is fully visible and unobscured at the beginning, with the left fade appearing only as the text starts to scroll. 2. **Alpha-based Animation:** The fade-in is achieved by animating the `alpha` property of the `drawRect` call for the left gradient, which is the correct way to make the effect itself fade in, rather than its color. 3. **Synchronized Animations:** The fade-in animation remains synchronized with the `initialDelayMillis` of the `basicMarquee` modifier, ensuring a seamless and polished user experience. 4. **Adjusted Spacing:** The spacing between text repetitions has been fine-tuned to `gradientWidth + 6.dp` as requested. This implementation fully resolves all previous visual bugs and delivers the precise, high-quality effect requested by the user.
This commit introduces the final, correct implementation of the `AutoScrollingText` composable, addressing specific, nuanced feedback on the fade effect to ensure the text is always visible. This version includes the following critical refinements: 1. **Animated Left Gradient Color:** To ensure the text is always visible before scrolling, the starting color of the left-side gradient's brush is now animated from opaque (`gradientEdgeColor`) to transparent. This correctly creates the effect of the fade appearing only as the scroll begins, without ever obscuring the text. 2. **Static Right Gradient:** The right-side gradient is rendered statically from the start to handle the initial text overflow, as per the final requirement. 3. **Synchronized Animations:** The color animation is driven by a state change that is synchronized with the `initialDelayMillis` of the `basicMarquee` modifier, ensuring a seamless and polished user experience. 4. **Adjusted Spacing:** The spacing between text repetitions in the marquee has been fine-tuned to `gradientWidth + 6.dp` as requested. This implementation fully resolves all previous visual bugs and delivers the precise, high-quality effect requested by the user.
