java - 在 2 个 RadioGroups 中选择 RadioButton 时显示隐藏备用 LinearLayouts
问题描述
六个 RadioButton 在 RadioGroup 中对齐为 3 列和 2 行，因此 RG 中有 6 个 RB-s。如果用户选择一个 RB，则在其正下方显示 image1 和 text1，并且在交替的 RB-s 下还显示 image1 和 text2。用户可以选择任何RB。正确的行为看起来像https://photos.app.goo.gl/NEqTaxsY6daxD3kJA

Image1 始终相同，而 text1 和 text2 不同。Text1 'You' 显示在选定的 RB 下，text2 'Yourfriend' 显示在交替的 RB-s 下。问题仍然是如何显示/隐藏 image1 和 text 1 或 text 2？我可以在同一列中的 RB-s 下显示/隐藏 image1 和 text-s，但不能交替 RB-s。
