Listview项目布局将线性布局推离屏幕

Question

I am new to android and am trying to create a list view row item as follows:

• On the far left of the listview item I need two stacked text views
• In the center of the listview item I need an additional two stacked text view
• On the far right I need a checkbox

I want to make the width of the center textviews a constant size, irrespective to the length of text.

Every time I adjust the middle linear layout, it pushes the checkbox off the screen unless I manually give it a width (which will not work for multiple screen sizes). Can someone please help?

I've tried using weights and all but I can't figure it out.

<RelativeLayout
