【问题描述】：

我有一个静态布局，并在程序化动态中设置了边距。边距工作正常，但仅在纵向视图中。这是xml布局

<LinearLayout

我犯了什么错误吗？端口视图

风景

在横向视图中更改当前项目后

【问题讨论】：

在横向模式下边距工作正常，但它不能适应屏幕..当布局加载第一次时间比它适合屏幕但触发点击事件后它不能保持适合屏幕。 .
问题出现在第三张图片中...点击任何项目后。

标签： android android-layout margins

【解决方案1】：

我终于找到了解决方案。在我发布的旧代码中，我写了这段代码

LinearLayout.LayoutParams params1 = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT);
params1.setMargins(0, 15, 0, 0);

我已经更改了下面的代码。这解决了我的问题。

final LinearLayout.LayoutParams params1 = (LinearLayout.LayoutParams) rl_home
                .getLayoutParams();
params1.setMargins(0, 15, 0, 0);
rl_home.setLayoutParams(params1);
