How to use Shape as drawable in imagespan

Question

I have a Pan image, but it only works with images, when I try to use a Hape the location of the image is as if n has no image, but also does not present any error.

       String text = exercicios.get(0).getPergunta();
    Log.i(TAG, exercicios.get(0).getPergunta());
    //String text = "texto # texto";

    //Posição onde colocar a imegem(posição da marca)
    int imagePos = text.indexOf("#");

    //Criar um SpannableString do texto
    SpannableString spannableString = new SpannableString(text);

    //Obter o drawable a inserir
    Drawable drawable = getResources().getDrawable(R.drawable.shapepergunta);
    drawable.setBounds(0, 0,drawable.getIntrinsicWidth(),drawable.getIntrinsicHeight());

    //Criar um ImageSpan do drawable
    ImageSpan imageSpan = new ImageSpan(drawable, ImageSpan.ALIGN_BASELINE);
    //Inserir a imagem(ImageSpan) no texto(SpannableString)
    spannableString.setSpan(imageSpan,imagePos,imagePos+1, Spanned.SPAN_INCLUSIVE_INCLUSIVE);
    //Atribuir o texto com a imagem ao TextView
    txvpergunta.setText(spannableString);

Shape:

    <?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
<corners
android:radius="14dp"
/>
<gradient
android:angle="45"
android:centerX="35%"
android:centerColor="#198CFF"
android:startColor="#449DEF"
android:endColor="#2F6699"
android:type="linear"
/>
<padding
android:left="0dp"
android:top="0dp"
android:right="0dp"
android:bottom="0dp"
/>
<stroke
android:width="1dp"
android:color="#878787"
/>
</shape>

As the Shape is declared it has no dimensions.

When it’s used as background or foreground other’s view no problem, since it fits the view dimension.

When used as span this does not happen. So you have to define its dimensions.

You can do it in two ways:

• Including the attribute size in xml:

  <?xml version="1.0" encoding="utf-8"?>
  <shape xmlns:android="http://schemas.android.com/apk/res/android"
      android:shape="rectangle" >
      <size
          android:width="32dp"
          android:height="16dp"/>
      <corners
          android:radius="14dp"/>
      <gradient
          android:angle="45"
          android:centerX="35%"
          android:centerColor="#198CFF"
          android:startColor="#449DEF"
          android:endColor="#2F6699"
          android:type="linear"/>
      <padding
          android:left="0dp"
          android:top="0dp"
          android:right="0dp"
          android:bottom="0dp"/>
      <stroke
          android:width="1dp"
          android:color="#878787"/>
  </shape>
  

• In java through setBounds():

  //Obter o drawable a inserir
  Drawable drawable = getResources().getDrawable(R.drawable.shapepergunta);
  drawable.setBounds(0, 0, 64, 32);
