How to access or translate text in Vector Drawable

I have a custom view which displays a drawable and detects touches. It has a number of drawable layers, some of which contain text, for example,

I have converted each SVG vector graphic into a vector drawable and want to be able to set the text to be a resource so I can substitute different translations.

The SVG xml code for the 'Hello box' above :-

<svg
   width="800"
   height="400"
   viewBox="0 0 800 400.00001"
   id="svg5772"
   version="1.1"
   inkscape:version="0.91 r13725"
   sodipodi:docname="HELLO in a box.svg">
  <defs
     id="defs5774" />
  <sodipodi:namedview
     id="base"
     pagecolor="#ffffff"
     bordercolor="#666666"
     borderopacity="1.0"
    <rect
       style="opacity:1;fill:#ffffff;fill-opacity:1;fill-rule:evenodd;stroke:#000000;stroke-width:2;stroke-linecap:round;stroke-linejoin:round;stroke-miterlimit:4;stroke-dasharray:none;stroke-dashoffset:0;stroke-opacity:1"
       id="rect6320"
       width="468.57144"
       height="128.57143"
       x="174.28572"
       y="786.64795"
       rx="0"
       ry="0" />
    <text
       xml:space="preserve"
       style="font-style:normal;font-weight:normal;font-size:40px;line-height:125%;font-family:sans-serif;letter-spacing:0px;word-spacing:0px;fill:#000000;fill-opacity:1;stroke:none;stroke-width:1px;stroke-linecap:butt;stroke-linejoin:miter;stroke-opacity:1"
       x="348.57141"
       y="869.50507"
       id="text6322"
       sodipodi:linespacing="125%"><tspan
         sodipodi:role="line"
         id="tspan6324"
         x="348.57141"
         y="869.50507">HELLO!!!</tspan></text>
  </g>
</svg>

</vector>

It looks very much like each letter of "HELLO!!!" text is converted into a path to be drawn directly to the canvas?!

So my question is, is there alternative way of displaying the vector graphic containing text on a canvas and therefore being able to use a resource for the text part? or am I stuck with creating different graphics for each language?

回答1:

Your conclusion is right.

Vector drawables are completely path based. This is the underlying reason for their animation because only a path is being changed. Hence they don't take text or image as input.

An option might be getting .svg through text(Some tool maybe?) and then convert it to xml for each language. If you are targeting larger localization, vector drawable may not be the right approach.

回答2:

You are going to have to use an approach that separates the localizable content from the drawable.

It's not clear what exactly you are doing, but if for example you want to have custom buttons, then you should make the VectorDrawable just be the custom button design. Then either use the drawable as a background to a TextView, or superimpose the text part as a TextView on top of an ImageView.
