LinearLayout is a view group that aligns all children in a single direction, vertically or horizontally. You can specify the layout direction with the android:orientation attribute. Note: For better performance and tooling support, you should instead build your layout with ConstraintLayout. All children of a LinearLayout are stacked one after the other, so a vertical list will only have one child per row, no matter how wide they are, and a horizontal list will only be one row high the height of the tallest child, plus padding.
A LinearLayout respects margin s between children and the gravity right, center, or left alignment of each child. This attribute assigns an "importance" value to a view in terms of how much space it should occupy on the screen. A larger weight value allows it to expand to fill any remaining space in the parent view.
Child views can specify a weight value, and then any remaining space in the view group is assigned to children in the proportion of their declared weight. Default weight is zero. You can also create linear layouts where the child elements use different amounts of space on the screen:.
The following code snippet shows how layout weights might work in a "send message" activity. The To field, Subject line, and Send button each take up only the height they need. This configuration allows the message itself to take up the rest of the activity's height. For details about the attributes available to each child view of a LinearLayoutsee LinearLayout.

Each item in the list is inside a horizontal LinearLayout with a WeightSum of 2. Here's an example:. These are all inside of a vertical LinearLayout. This part works perfectly. The TextView on the left is right-justified and takes up half of the screen width.
The TextView on the right is left-justified and takes up half the screen width. The first TextView should be right justified and the second one should be left justified, in each row. Instead the first TextView is left justified and the second TextView is bumped up right next to it, left-justified.
This just doesn't make sense to me: SetTextColor does not seem to work. I've tried using constants:. What's odd is, a lot of the methods are working. In fact:.
As for the layout, I got that mostly fixed it's still not right-justifying the first textviews. I was neglecting to add the LayoutParameters to their appropriate views.
But I still can't get the color issue figured out. Okay, I've now fixed everything except the textcolor. If someone could please help me get around the SetTextColor not working, that would be fantastic. I figured it out just before I went home last night. Well, either way. I ended up moving the set text color after setting the appearance and that fixed it. I didn't realize that setting the appearance set the color. Not sure why.

You should be careful about over-using the LinearLayout. If you begin nesting multiple LinearLayout s, you may want to consider using a RelativeLayout instead.
Carefully inspect this XML. There is a root LinearLayout that defines its orientation to be vertical — all child View s of which it has two will be stacked vertically.
The first child is another LinearLayout that uses a horizontal orientation and the second child is a LinearLayout that uses a vertical orientation. Each of these nested LinearLayout s contain several TextView elements, which are oriented with each other in the manner defined by their parent LinearLayout.
