Vertical line using XML drawable

Question

I m trying to figure out how to define a vertical line  1dp thick  to be used as a drawable   To make a horizontal one  it s pretty straightforward    lt shape xmlns android  http   schemas android com apk res android  android shape  line  gt       lt stroke android width  1dp  android color   0000FF   gt       lt size android height  50dp    gt        lt  shape gt    The question is  how to make this line vertical   Yes  there are workarounds  such as drawing a rectangle shape 1px thick  but that complicates the drawable XML  if it consists of multiple  lt item gt  elements   Anyone had any chance with this   UPDATE  Case is still unsolved  However  For anyone on a Android documentation crusade - you might find this useful  Missing Android XML Manual   UPDATE  I found no other way other than the one that I marked as correct  It does the trick though feels a bit  heavy   thus if you happen to know the answer don t forget to share

Although  CommonsWare s solution works  it can t be used e  g  in a layer-list drawable  The options combining  lt rotate gt  and  lt shape gt  cause the problems with size  Here is a solution using the Android Vector Drawable  This Drawable is a 1x10dp white line  can be adjusted by modifying the width  height and strokeColor properties    lt  xml version  quot 1 0 quot  encoding  quot utf-8 quot   gt   lt vector xmlns android  quot http   schemas android com apk res android quot      android viewportWidth  quot 1 quot      android viewportHeight  quot 10 quot      android width  quot 1dp quot      android height  quot 10dp quot  gt        lt path         android strokeColor  quot  FFFFFF quot          android strokeWidth  quot 1 quot          android pathData  quot M0 5 0 V10 quot    gt    lt  vector gt

I needed to add my views dynamically programmatically  so adding an extra view would have been cumbersome  My view height was WRAP CONTENT  so I couldn t use the rectangle solution  I found a blog-post here about extending TextView  overriding onDraw   and painting in the line  so I implemented that and it works well  See my code below   public class NoteTextView extends TextView       public NoteTextView Context context           super context             private Paint paint   new Paint         Override     protected void onDraw Canvas canvas            super onDraw canvas           paint setColor Color parseColor   F00000FF             paint setStrokeWidth 0           paint setStyle Paint Style FILL           canvas drawLine 0  0  0  getHeight    paint             I needed a vertical line on the left  but the drawline parameters are drawLine startX  startY  stopX  stopY  paint  so you can draw any straight line in any direction across the view   Then in my activity I have NoteTextView note   new NoteTextView this   Hope this helps

Seems like there s a bug when using rotate drawable in Android M and above as per the thread here   stackoverflow com a 8716798 3849039 As per my opinion  creating a custom view is the best solution for this  Below link save my time  https   gist github com mlagerberg 4aab34e6f8bc66b1eef7 revisions

I came up with a different solution  The idea is to fill the drawable first with the color that you like the line to be and then fill the whole area again with the background color while using left or right padding  Obviously this only works for a vertical line in the far left or right of your drawable    lt  xml version  1 0  encoding  utf-8   gt   lt layer-list xmlns android  http   schemas android com apk res android   gt       lt item android drawable   color divider color    gt       lt item android left  6dp  android drawable   color background color    gt   lt  layer-list gt

You can use a shape but instead of a line make it rectangle    android shape  rectangle  gt   lt stroke     android width  5dp      android color   ff000000      android dashGap  10px      android dashWidth  30px    gt      and In your layout use this      lt ImageView     android layout width  7dp      android layout height  match parent      android src   drawable dashline      android layout alignParentTop  true      android layout centerHorizontal  true      android layerType  software   gt    You might have to play with the width  depending on the size of the dashes  to get it into a single line   Hope this helps Cheers

To make a vertical line  just use a rectangle with width of 1dp    lt shape gt       lt size         android width  1dp          android height  16dp    gt       lt solid         android color   c8cdd2    gt   lt  shape gt    Don t use stroke  use solid  which is the  fill  color  to specify the color of the line

Depends  where you want to have the vertical line  but if you want a vertical border for example  you can have the parent view have a background a custom drawable  And you can then define the drawable like this    lt  xml version  1 0  encoding  utf-8   gt   lt layer-list xmlns android  http   schemas android com apk res android   gt       lt item gt           lt shape             android shape  rectangle  gt               lt stroke android width  1dp  android color   000000    gt               lt solid android color   00ffffff    gt            lt  shape gt       lt  item gt        lt item android right  1dp  gt           lt shape android shape  rectangle  gt               lt solid android color   00ffffff    gt           lt  shape gt       lt  item gt    lt  layer-list gt    This example will create a 1dp thin black line on the right side of the view  that will have this drawable as an background

You can nest your shape inside a rotate tag    lt rotate xmlns android  http   schemas android com apk res android      android fromDegrees  90      android toDegrees  90  gt       lt shape          android shape  line  gt           lt stroke             android width  1dp              android color   ff00ff              android dashWidth  1dp              android dashGap  2dp    gt       lt  shape gt   lt  rotate gt    However  the only problem is the layout params defined in your layout xml will be the dimensions used to draw the original shape  Meaning if you want your line to be 30dp tall  you need to define a layout width of 30dp in your layout xml   But the final width will also be 30dp in that case  which is likely undesirable for most situations  This essentially means both width and height have to be the same value  the value of your desired length for the line   I couldn t figure out how to fix this   This seems to be the  android way  solution  but unless there s some fix or workaround for the dimensions issue I mention then this likely won t work for most people   What we really need is an orientation attribute in  lt shape  gt  or  lt stroke  gt    You can also try referencing another drawable in the rotate tag s attributes  such as    lt rotate xmlns android  http   schemas android com apk res android      android fromDegrees  90      android toDegrees  90      android drawable   drawable horizontal line    gt    However I haven t tested this and expect it to have the same issues   -- EDIT --  Oh  I actually figured out a fix   You can use a negative margin in your layout xml to get rid of the undesired extra space  Such as    lt ImageView     android layout width  35dp      android layout height  35dp      android layout marginLeft  -15dp      android layout marginRight  -15dp      android src   drawable dashed vertical line    gt

You can use the rotate attribute    lt item gt       lt rotate         android fromDegrees  90          android toDegrees  90          android pivotX  50           android pivotY  50    gt           lt shape             android shape  line              android top  1dip   gt               lt stroke                 android width  1dip                     gt           lt  shape gt       lt  rotate gt   lt  item gt

Instead of a shape  you could try a View   lt View     android layout width  quot 1dp quot      android layout height  quot match parent quot      android background  quot  FF0000FF quot    gt   I have only used this for horizontal lines  but I would think it would work for vertical lines as well  Use   lt View     android layout width  quot match parent quot      android layout height  quot 1dp quot      android background  quot  FF0000FF quot    gt   for a horizontal line
