问题 I'm trying to build a GirdLayout programmatically with 2 columns and I want these columns to have equal width set at half the width of the screen. I figured out you can do this since API 21 or with the support v7 GirdLayout view. I see examples that uses android:layout_columnWeight="1" to do this.

I'm trying to create a listview row that basically looks like this: | TextView | View 1 | View 2 | All views contain variable width elements. The TextView has ellipsize="end" set. View 1 should align left of the TextView, while View 2 should align to the right of the screen. So, normally,

问题 I am developing an android application with showing images. I am using grid view to show the images in my application. But default gridview is horizontal scrolling I want to show the images in vertical scrolling grid view. Please suggest me a way to achieve vertical scrolling in gridview.
