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.
