However it generated the below UI
Notice how the colorfull bar is not aligned properly with the upper and lower text boxes, as the first image indicated via a dotted line (the dotted line shows the where the edge of each colourful tile should be, in aligned with the textboxes.
Also notice my text boxes are different than what is expected.
How can I make it as displayed in the first image?
Here I have fix your inner layout, change drawable and color.., etc
Instead of Edittext use your TextInput layout. It is giving error while compiling so i changed it to Edittext
