I would like to register clicks on a text wrapped in a ClickableSpan only if they are clicked for over say 1 second. Is there any way to do this? If not, capturing a double click would also be fine.
It would be great if the onClick method captured an event that had some meta data about the click - then I could say ignore if the click length was short.
Any advice?
Thanks, Victor
A ClickableSpan for a TextLink. URLSpan. Implementation of the ClickableSpan that allows setting a url string. If an object of this type is attached to the text of a TextView with a movement method of LinkMovementMethod, the affected spans of text can be selected.
This example demonstrates how do I set the part of the Android textView as clickable. Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project. Step 2 − Add the following code to res/layout/activity_main. xml.
Just like Buttons and ImageViews we can add onClickListeners to TextViews by simply adding the attribute android:onClick="myMethod" to your TextView XML tag. The other way, TextView tv = (TextView) this.
I want to do the same, the only method that comes to mind is custom MovementMethod class replacing LinkMovementMethod and a replacement for ClickableSpan that adds a long click abstract method. It is actually quite simple:
EDIT: Works like a charm. I've made some stupid mistakes like downloading LinkMovementMethod from different Android version and not using the new ClickableSpan class in setSpan(), but nothing serious.
In case anyone needs it, I found it on this place
package leeon.mobile.BBSBrowser;
import android.text.Layout;
import android.text.Selection;
import android.text.Spannable;
import android.text.method.LinkMovementMethod;
import android.text.method.MovementMethod;
import android.view.MotionEvent;
import android.widget.TextView;
public class LongClickLinkMovementMethod extends LinkMovementMethod {
private Long lastClickTime = 0l;
private int lastX = 0;
private int lastY = 0;
@Override
public boolean onTouchEvent(TextView widget, Spannable buffer,
MotionEvent event) {
int action = event.getAction();
if (action == MotionEvent.ACTION_UP ||
action == MotionEvent.ACTION_DOWN) {
int x = (int) event.getX();
int y = (int) event.getY();
lastX = x;
lastY = y;
int deltaX = Math.abs(x-lastX);
int deltaY = Math.abs(y-lastY);
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);
LongClickableSpan[] link = buffer.getSpans(off, off, LongClickableSpan.class);
if (link.length != 0) {
if (action == MotionEvent.ACTION_UP) {
if (System.currentTimeMillis() - lastClickTime < 1000)
link[0].onClick(widget);
else if (deltaX < 10 && deltaY < 10)
link[0].onLongClick(widget);
} else if (action == MotionEvent.ACTION_DOWN) {
Selection.setSelection(buffer,
buffer.getSpanStart(link[0]),
buffer.getSpanEnd(link[0]));
lastClickTime = System.currentTimeMillis();
}
return true;
}
}
return super.onTouchEvent(widget, buffer, event);
}
public static MovementMethod getInstance() {
if (sInstance == null)
sInstance = new LongClickLinkMovementMethod();
return sInstance;
}
private static LongClickLinkMovementMethod sInstance;
}

LongClickableSpan in the same place:
package leeon.mobile.BBSBrowser;
import android.text.style.ClickableSpan;
import android.view.View;
public abstract class LongClickableSpan extends ClickableSpan {
abstract public void onLongClick(View view);
}
