Como mostrar imagen img scr en formato HTML con fromHTML


Mostrar una imagen usando fromHTML, de forma que podremos cogerla de una internet con la etiqueta img de HTML.

Antes de este tutorial, aunque muy básico, puede que desees familiarizarte con fromHTML. Para ello puedes pasarte por un ejemplo en el que sólo se utiliza texto en HTML en este tutorial. En él se muestra el hipertexto en un AlertDialog, pero es igualmente sencillo asignarlo a un TextView.

Cuando deseamos utilizar HTML en un TextView, por ejemplo, podemos llamar al paquete android.text.html, dejando que él actúe sobre nuestro texto, aplicando la vista indicadas en las etiquetas que le dan formato. En este HTML podemos incluso utilizar llamadas a imágenes con la tag img src.

Creamos  mini-aplicación para coger el HTML y lo aplicamos a un TextView para mostrarlo. Para ello, debemos crear una aplicación desde el principio,  crear un TextView para insertar el hipertexto en HTML (con imagen incluida en este caso), y finalmente llamar a la clase android.text.html. Para que las imágenes en el HTML aparezcan debemos implementar la función getImageHTML, que devolverá una instancia de la clase ImageGetter, necesaria para ello.

Vemos una captura de la mini-aplicación:

Y a continuación mostramos el texto comentado:

Código fuente Java:

[sourcecode language=”java”]
import android.os.Bundle;
import android.text.Html;
import android.text.Spanned;
import android.text.Html.ImageGetter;
import android.util.Log;
import android.widget.TextView;

public class HtmlFromHtmlImageActivity extends Activity {
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {

String html = "Tus ejemplos en<br/><br/><br/><img src=’’ />";

Spanned s = Html.fromHtml(html,getImageHTML(),null);
TextView txt = (TextView)findViewById(;

public ImageGetter getImageHTML(){
ImageGetter ig = new ImageGetter(){
public Drawable getDrawable(String source) {
Drawable d = Drawable.createFromStream(new URL(source).openStream(), "src name");
d.setBounds(0, 0, d.getIntrinsicWidth(),d.getIntrinsicHeight());
return d;
}catch(IOException e){
return null;
return ig;

  1. Super!!!! Busqué ene en internet y no pude encontrar algo que me funcionara. Este código funciona a las mil maravillas.
    Ahora, no se si será mucho pedir pero, se podrá modificar para que en vez de tomar la imagen de internet la tome de asset o de res/drawable-hdpi.

    • Buenas Ricardo!
      pues simplemente tendríamos que cambiar la funcion ImageGetter:
      [sourcecode language=”java”]
      public ImageGetter getImageHTML(){
      ImageGetter ig = new ImageGetter(){
      public Drawable getDrawable(String source) {
      int resID = getResources().getIdentifier(source, "drawable", ""); //nombre del paquete al final
      Drawable d = new BitmapDrawable( BitmapFactory.decodeResource( HtmlFromHtmlImageActivity.this.getBaseContext().getResources(), resID));
      d.setBounds(0, 0, d.getIntrinsicWidth(),d.getIntrinsicHeight());
      return d;
      return ig;
      Y ahora en onCreate simplemente tendras la siguiente linea:
      [sourcecode language=”java”]
      String html = "Tus ejemplos en<br/><br/><br/><img src=’icon’ />";
      Donde ‘icon’ es el nombre de la imagen que tengo en el directorio: drawable-hdpi/icon.png
      Espero que te sirva.

        • Does the style attribute works?I have a text that was retaecd using Html.fromHtml(htmlString), but once its rendered, it has an underline.Any idea on how to remove the underline?Thanks.

      • I’d first check whether it’s inuerldned because of a link or a pair of u tags (or some other reason). You may have to modify the Spanned that is returned from the Html.fromHtml() call (or modify the HTML being passed to that beforehand).

  2. Hola amigos bueno quisiera agradecerles sobre los tutos que hacen que son de mucha ayuda para los que empezamos a programar en android.
    Tengo una consulta estaba observando sobre el Articulo de la Clase AsyncTask y tengo una duda sobre ese tema. Mi duda es la siguiente ahi tu le das un valor maximo de 1400000 al progressDialog y que valla aumentando de uno en uno el progressDialog hasta que llegue a 1400000 pero mi duda es la siguiente yo tengo un login en Android con Conexion a Pagina web y cuando lleno mi formulario del login y doy click en aceptar, empieza a ejecutar el codigo pero al dar click en el boton se pone como la pantalla como un poco lento osea creo que tiene un tiempo que se demora en comunicarse con la pagina web y hacer la consulta con la BD de la pagina web y verificar si existe el usuario o no. Mi duda es la siguiente como yo calculo el tiempo que se demora en hacer la consulta a la pagina web con Conexion a Base de Datos, para asi yo poner un progressDialog y ya no darle 1400000 sino el tiempo que he calculado en consultar a la Pagina web con Base de Datos. Gracias de antemano espero su pronta respuesta. Saludos desde PERU.
