Solved something very similar in a very nice way.
I wanted to have text that has a link which is clickable!! and i wanted to be able to press the text Where there is no link and have a on click listener in it.
I took the LinkMovementMethod from grepcode and changed it a little Copy and past this class and copy the bottom and it will work :
import android.text.Layout;
import android.text.NoCopySpan;
import android.text.Selection;
import android.text.Spannable;
import android.text.method.MovementMethod;
import android.text.method.ScrollingMovementMethod;
import android.text.style.ClickableSpan;
import android.view.KeyEvent;
import android.view.MotionEvent;
import android.view.View;
import android.widget.TextView;
public class
CustomLinkMovementMethod
extends ScrollingMovementMethod
{
private static final int CLICK = 1;
private static final int UP = 2;
private static final int DOWN = 3;
public abstract interface TextClickedListener {
public abstract void onTextClicked();
}
TextClickedListener listener = null;
public void setOnTextClickListener(TextClickedListener listen){
listener = listen;
}
@Override
public boolean onKeyDown(TextView widget, Spannable buffer,
int keyCode, KeyEvent event) {
switch (keyCode) {
case KeyEvent.KEYCODE_DPAD_CENTER:
case KeyEvent.KEYCODE_ENTER:
if (event.getRepeatCount() == 0) {
if (action(CLICK, widget, buffer)) {
return true;
}
}
}
return super.onKeyDown(widget, buffer, keyCode, event);
}
@Override
protected boolean up(TextView widget, Spannable buffer) {
if (action(UP, widget, buffer)) {
return true;
}
return super.up(widget, buffer);
}
@Override
protected boolean down(TextView widget, Spannable buffer) {
if (action(DOWN, widget, buffer)) {
return true;
}
return super.down(widget, buffer);
}
@Override
protected boolean left(TextView widget, Spannable buffer) {
if (action(UP, widget, buffer)) {
return true;
}
return super.left(widget, buffer);
}
@Override
protected boolean right(TextView widget, Spannable buffer) {
if (action(DOWN, widget, buffer)) {
return true;
}
return super.right(widget, buffer);
}
private boolean action(int what, TextView widget, Spannable buffer) {
boolean handled = false;
Layout layout = widget.getLayout();
int padding = widget.getTotalPaddingTop() +
widget.getTotalPaddingBottom();
int areatop = widget.getScrollY();
int areabot = areatop + widget.getHeight() - padding;
int linetop = layout.getLineForVertical(areatop);
int linebot = layout.getLineForVertical(areabot);
int first = layout.getLineStart(linetop);

selStart = selEnd = buffer.length();
}
}
if (selStart > last)
selStart = selEnd = Integer.MAX_VALUE;
if (selEnd < first)
selStart = selEnd = -1;
switch (what) {
case CLICK:
if (selStart == selEnd) {
return false;
}
ClickableSpan[] link = buffer.getSpans(selStart, selEnd, ClickableSpan.class);
if (link.length != 1)
return false;
link[0].onClick(widget);
break;
case UP:
int beststart, bestend;
beststart = -1;

for (int i = 0; i < candidates.length; i++) {

}
}

return false;
}
public boolean onKeyUp(TextView widget, Spannable buffer,
int keyCode, KeyEvent event) {
return false;
}
@Override
public boolean onTouchEvent(TextView widget, Spannable buffer,

int action = event.getAction();
if (action == MotionEvent.ACTION_UP ||
action == MotionEvent.ACTION_DOWN) {
int x = (int) event.getX();
int y = (int) event.getY();
x -= widget.getTotalPaddingLeft();
y -= widget.getTotalPaddingTop();
x += widget.getScrollX();
y += widget.getScrollY();
Layout layout = widget.getLayout();
int line = layout.getLineForVertical(y);
int off = layout.getOffsetForHorizontal(line, x);
ClickableSpan[] link = buffer.getSpans(off, off, ClickableSpan.class);
if (link.length != 0) {
if (action == MotionEvent.ACTION_UP) {

} else if (action == MotionEvent.ACTION_DOWN) {

if(listener != null)
listener.onTextClicked();
}
}
}
return super.onTouchEvent(widget, buffer, event);
}
public void initialize(TextView widget, Spannable text) {
Selection.removeSelection(text);
text.removeSpan(FROM_BELOW);
}
public void onTakeFocus(TextView view, Spannable text, int dir) {
Selection.removeSelection(text);
if ((dir & View.FOCUS_BACKWARD) != 0) {
text.setSpan(FROM_BELOW, 0, 0, Spannable.SPAN_POINT_POINT);
} else {
text.removeSpan(FROM_BELOW);
}
}
public static MovementMethod getInstance() {
if (sInstance == null)
sInstance = new CustomLinkMovementMethod();
return sInstance;
}
private static CustomLinkMovementMethod sInstance;
private static Object FROM_BELOW = new NoCopySpan.Concrete();
}
Then in your code where the text view is add:
CustomLinkMovementMethod link = (CustomLinkMovementMethod)CustomLinkMovementMethod.getInstance();
link.setOnTextClickListener(new CustomLinkMovementMethod.TextClickedListener() {
@Override
public void onTextClicked() {
Toast.makeText(UserProfileActivity.this, "text Pressed", Toast.LENGTH_LONG).show();
}
});
YOUR_TEXTVIEW.setMovementMethod(link);
