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"/>
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.
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
