片段没有宽度也没有高度

Question

您看到的对话框是一个带有对话框主题的activity。里面的布局是应与其宽度和高度相匹配的片段。它是使用 FragmentTransaction class 以编程方式添加的。

问题是片段布局被挤压在一起，看起来很糟糕。我在片段布局和 activitys 的 xml 中使用了 match_parent。

如何阻止对话框被挤压在一起并具有更大的 "natural" 大小？

Answer 1

自定义警告对话框的高度和宽度android。以下是代码

WindowManager.LayoutParams params = new WindowManager.LayoutParams();

params.copyFrom(alertDialog.getWindow().getAttributes());
params.width = 100;
params.height = 400;
params.x=-190;
params.y=80;
alertDialog.getWindow().setAttributes(params);

不确定，但希望它会起作用。
