Android：如何给 LinearLayout 一个最大宽度？

Question

I am designing a layout for my Android app.

I want a LinearLayout within a ScrollView to stretch. I achieved this with layout_width:match_parent. However, I don't want to stretch it beyond 500dp.

The layout should look something like this:

So far I've tried android:maxWidth and app:layout_constraintWidth_max (with layout_width="0dp" and layout_width="match_parent") .

How does on achieve this layout without extra files for certain screen sizes?

You could set the width of the linearLayout programmatically in onCreate() for each screen mode:

LinearLayout linearLayout = findViewById(R.id.ll);

        if(getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE){
            linearLayout.setLayoutParams(new LinearLayout.LayoutParams(500, ViewGroup.LayoutParams.WRAP_CONTENT));
        }
        else {
            linearLayout.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
        }
