How to add image in a TextView text?


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


I tried many different solutions and this for me was the best:

SpannableStringBuilder ssb = new SpannableStringBuilder(" Hello world!");ssb.setSpan(new ImageSpan(context, R.drawable.image), 0, 1, Spannable.SPAN_INCLUSIVE_INCLUSIVE);tv_text.setText(ssb, TextView.BufferType.SPANNABLE);

This code uses a minimum of memory.
