How to add image in a TextView text?

Question

I've searched around on Google and came across this site where I found a question similar to mine in which how to include a image in a TextView text, for example "hello my name is [image]", and the answer was this:

ImageSpan is = new ImageSpan(context, resId); text.setSpan(is, index, index + strLength, 0); 

I would like to know in this code,

1. What am I supposed to type or do in the context?
2. Am I supposed to do something to the text.setSpan() like import or reference or leave it text?

If someone can break this down for me that would be much appreciated.

Try this ..

    txtview.setCompoundDrawablesWithIntrinsicBounds(                     R.drawable.image, 0, 0, 0); 

Also see this.. http://developer.android.com/reference/android/widget/TextView.html

Try this in xml file

    <TextView         android:id="@+id/txtStatus"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_gravity="center"         android:drawableLeft="@drawable/image"         android:drawablePadding="5dp"         android:maxLines="1"         android:text="@string/name"/>

com/xyz/customandroid/ TextViewWithImages .java:

import java.util.regex.Matcher; import java.util.regex.Pattern;  import android.content.Context; import android.text.Spannable; import android.text.style.ImageSpan; import android.util.AttributeSet; import android.util.Log; import android.widget.TextView;  public class TextViewWithImages extends TextView {      public TextViewWithImages(Context context, AttributeSet attrs, int defStyle) {         super(context, attrs, defStyle);     }     public TextViewWithImages(Context context, AttributeSet attrs) {         super(context, attrs);     }     public TextViewWithImages(Context context) {         super(context);     }     @Override     public void setText(CharSequence text, BufferType type) {         Spannable s = getTextWithImages(getContext(), text);         super.setText(s, BufferType.SPANNABLE);     }      private static final Spannable.Factory spannableFactory = Spannable.Factory.getInstance();      private static boolean addImages(Context context, Spannable spannable) {         Pattern refImg = Pattern.compile("\\Q[img src=\\E([a-zA-Z0-9_]+?)\\Q/]\\E");         boolean hasChanges = false;          Matcher matcher = refImg.matcher(spannable);     while (matcher.find()) {         boolean set = true;         for (ImageSpan span : spannable.getSpans(matcher.start(), matcher.end(), ImageSpan.class)) {             if (spannable.getSpanStart(span) >= matcher.start()              && spannable.getSpanEnd(span) <= matcher.end()                ) {                 spannable.removeSpan(span);             } else {                 set = false;                 break;             }         }         String resname = spannable.subSequence(matcher.start(1), matcher.end(1)).toString().trim();         int id = context.getResources().getIdentifier(resname, "drawable", context.getPackageName());         if (set) {             hasChanges = true;             spannable.setSpan(  new ImageSpan(context, id),                                 matcher.start(),                                 matcher.end(),                                 Spannable.SPAN_EXCLUSIVE_EXCLUSIVE                              );         }     }          return hasChanges;     }     private static Spannable getTextWithImages(Context context, CharSequence text) {         Spannable spannable = spannableFactory.newSpannable(text);         addImages(context, spannable);         return spannable;     } } 

Use:

in res/layout/mylayout.xml:

            <com.xyz.customandroid.TextViewWithImages                 android:layout_width="wrap_content"                 android:layout_height="wrap_content"                 android:textColor="#FFFFFF00"                 android:text="@string/can_try_again"                 android:textSize="12dip"                 style=...                 /> 

Note that if you place TextViewWithImages.java in some location other than com/xyz/customandroid/, you also must change the package name, com.xyz.customandroid above.

in res/values/strings.xml:

<string name="can_try_again">Press [img src=ok16/] to accept or [img src=retry16/] to retry</string> 

where ok16.png and retry16.png are icons in the res/drawable/ folder
