解决方案
我已经实现了一个小类，借助它您可以处理对 TextView 本身的长时间点击以及对 TextView 中链接的点击。
布局
TextView android:id="@+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:autoLink="all"/>
TextViewClickMovement.java
import android.content.Context;
import android.text.Layout;
import android.text.Spannable;
import android.text.method.LinkMovementMethod;
import android.text.style.ClickableSpan;
import android.util.Patterns;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.widget.TextView;
public class TextViewClickMovement extends LinkMovementMethod {
private final String TAG = TextViewClickMovement.class.getSimpleName();
private final OnTextViewClickMovementListener mListener;
private final GestureDetector mGestureDetector;
private TextView mWidget;
private Spannable mBuffer;
public enum LinkType {
/** Indicates that phone link was clicked */
PHONE,
/** Identifies that URL was clicked */
WEB_URL,
/** Identifies that Email Address was clicked */
EMAIL_ADDRESS,
/** Indicates that none of above mentioned were clicked */
NONE
}
/**
* Interface used to handle Long clicks on the {@link TextView} and taps
* on the phone, web, mail links inside of {@link TextView}.
*/
public interface OnTextViewClickMovementListener {
/**
* This method will be invoked when user press and hold
* finger on the {@link TextView}
*
* @param linkText Text which contains link on which user presses.
* @param linkType Type of the link can be one of {@link LinkType} enumeration
*/
void onLinkClicked(final String linkText, final LinkType linkType);
/**
*
* @param text Whole text of {@link TextView}
*/
void onLongClick(final String text);
}
public TextViewClickMovement(final OnTextViewClickMovementListener listener, final Context context) {
mListener = listener;
mGestureDetector = new GestureDetector(context, new SimpleOnGestureListener());
}
@Override
public boolean onTouchEvent(final TextView widget, final Spannable buffer, final MotionEvent event) {
mWidget = widget;
mBuffer = buffer;
mGestureDetector.onTouchEvent(event);
return false;
}
/**
* Detects various gestures and events.
* Notify users when a particular motion event has occurred.
*/
class SimpleOnGestureListener extends GestureDetector.SimpleOnGestureListener {
@Override
public boolean onDown(MotionEvent event) {
// Notified when a tap occurs.
return true;
}
@Override
public void onLongPress(MotionEvent e) {
// Notified when a long press occurs.
final String text = mBuffer.toString();
if (mListener != null) {
Log.d(TAG, "----> Long Click Occurs on TextView with ID: " + mWidget.getId() + "\n" +
"Text: " + text + "\n<----");
mListener.onLongClick(text);
}
}
@Override
public boolean onSingleTapConfirmed(MotionEvent event) {
// Notified when tap occurs.
final String linkText = getLinkText(mWidget, mBuffer, event);
LinkType linkType = LinkType.NONE;
if (Patterns.PHONE.matcher(linkText).matches()) {
linkType = LinkType.PHONE;
}
else if (Patterns.WEB_URL.matcher(linkText).matches()) {
linkType = LinkType.WEB_URL;
}
else if (Patterns.EMAIL_ADDRESS.matcher(linkText).matches()) {
linkType = LinkType.EMAIL_ADDRESS;
}
if (mListener != null) {
Log.d(TAG, "----> Tap Occurs on TextView with ID: " + mWidget.getId() + "\n" +
"Link Text: " + linkText + "\n" +
"Link Type: " + linkType + "\n<----");
mListener.onLinkClicked(linkText, linkType);
}
return false;
}
private String getLinkText(final TextView widget, final Spannable buffer, final MotionEvent event) {
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) {
return buffer.subSequence(buffer.getSpanStart(link[0]),
buffer.getSpanEnd(link[0])).toString();
}
return "";
}
}
}
用法
String str_links = "<a href='http://google.com'>Google</a><br /><a href='http://facebook.com'>Facebook</a>";
text_view.setText( Html.fromHtml( str_links ) );
text_view.setMovementMethod(new TextViewClickMovement(this, context));
