How do you create a linear layout in Java?
To create a linear layout in which each child uses the same amount of space on the screen, set the android:layout_height of each view to “0dp” (for a vertical layout) or the android:layout_width of each view to “0dp” (for a horizontal layout). Then set the android:layout_weight of each view to “1” .
What are the attributes of linear layout?

|---|---|
| android:baselineAligned | When set to false, prevents the layout from aligning its children’s baselines. |
