如何动态设置android的FrameLayout的宽度和高度? [英] How to set Width and Height of FrameLayout dynamically android?

问题描述

我正在尝试设置2个框架布局的宽度和高度，这是2个片段的容器，这两个片段都是线性布局的子代.

I am trying to set the width and height of 2 frame layouts which are the containers for 2 fragments, both being children of a Linear Layout.

但是无论何时我用

frameLayout.setLayoutParams(new FrameLayout.LayoutParams(100,100);

这会导致类强制转换异常

it is resulting in a class cast Exception

java.lang.ClassCastException:android.widget.FrameLayout $ LayoutParams无法转换为android.widget.LinearLayout $ LayoutParams

java.lang.ClassCastException: android.widget.FrameLayout$LayoutParams cannot be cast to android.widget.LinearLayout$LayoutParams

推荐答案

使用此方法...

.setLayoutParams(new LinearLayout.LayoutParams(100,100);

代替您的方法....

instead of your method ....

.setLayoutParams(new FrameLayout.LayoutParams(100,100)

注意:-ClassCastException问题发生在您的班级与其他班级不同而您要投射...时.

Note:- ClassCastException problem happen when your class is different other class, you want to cast....
