Android ScrollView stealing touch events from child WebView

I have a layout where a WebView is inside a ScrollView, and I want to be able to switch between these two to decide which one receives the touch events. Unfortunately no matter what I do, the ScrollView seems to steal the touch events from the WebView, making it impossible to pan & zoom smoothly in the WebView. Is there some solution for this?
I have tried ScrollView.SetOnTouchListener(); and set a listener that returns true, this stops the ScrollView from scrolling but does not prevent the touch events being intercepted before they reach the WebView.
I have also tried WebView.Parent.RequestDisallowInterceptTouchEvent(true); and WebView.Parent.RequestDisallowInterceptTouchEvent(true); which both seem to have no effect.

Try using NestedScrollView and implement NestedScrollingChild to a custom WebView.
Reference Link
and some code
public class NestedWebView extends WebView implements NestedScrollingChild {
private int mLastY;
private final int[] mScrollOffset = new int[2];
private final int[] mScrollConsumed = new int[2];
private int mNestedOffsetY;
private NestedScrollingChildHelper mChildHelper;
public NestedWebView(Context context) {
this(context, null);
}
public NestedWebView(Context context, AttributeSet attrs) {
this(context, attrs, android.R.attr.webViewStyle);
}
public NestedWebView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
mChildHelper = new NestedScrollingChildHelper(this);
setNestedScrollingEnabled(true);
}
#Override
public boolean onTouchEvent(MotionEvent ev) {
boolean returnValue = false;
MotionEvent event = MotionEvent.obtain(ev);
final int action = MotionEventCompat.getActionMasked(event);
if (action == MotionEvent.ACTION_DOWN) {
mNestedOffsetY = 0;
}
int eventY = (int) event.getY();
event.offsetLocation(0, mNestedOffsetY);
switch (action) {
case MotionEvent.ACTION_MOVE:
int deltaY = mLastY - eventY;
// NestedPreScroll
if (dispatchNestedPreScroll(0, deltaY, mScrollConsumed, mScrollOffset)) {
deltaY -= mScrollConsumed[1];
mLastY = eventY - mScrollOffset[1];
event.offsetLocation(0, -mScrollOffset[1]);
mNestedOffsetY += mScrollOffset[1];
}
returnValue = super.onTouchEvent(event);
// NestedScroll
if (dispatchNestedScroll(0, mScrollOffset[1], 0, deltaY, mScrollOffset)) {
event.offsetLocation(0, mScrollOffset[1]);
mNestedOffsetY += mScrollOffset[1];
mLastY -= mScrollOffset[1];
}
break;
case MotionEvent.ACTION_DOWN:
returnValue = super.onTouchEvent(event);
mLastY = eventY;
// start NestedScroll
startNestedScroll(ViewCompat.SCROLL_AXIS_VERTICAL);
break;
case MotionEvent.ACTION_UP:
case MotionEvent.ACTION_CANCEL:
returnValue = super.onTouchEvent(event);
// end NestedScroll
stopNestedScroll();
break;
}
return returnValue;
}
// Nested Scroll implements
#Override
public void setNestedScrollingEnabled(boolean enabled) {
mChildHelper.setNestedScrollingEnabled(enabled);
}
#Override
public boolean isNestedScrollingEnabled() {
return mChildHelper.isNestedScrollingEnabled();
}
#Override
public boolean startNestedScroll(int axes) {
return mChildHelper.startNestedScroll(axes);
}
#Override
public void stopNestedScroll() {
mChildHelper.stopNestedScroll();
}
#Override

return mChildHelper.hasNestedScrollingParent();
}
#Override
public boolean dispatchNestedScroll(int dxConsumed, int dyConsumed, int dxUnconsumed, int dyUnconsumed,
int[] offsetInWindow) {
return mChildHelper.dispatchNestedScroll(dxConsumed, dyConsumed, dxUnconsumed, dyUnconsumed, offsetInWindow);
}
#Override
public boolean dispatchNestedPreScroll(int dx, int dy, int[] consumed, int[] offsetInWindow) {
return mChildHelper.dispatchNestedPreScroll(dx, dy, consumed, offsetInWindow);
}
#Override
public boolean dispatchNestedFling(float velocityX, float velocityY, boolean consumed) {
return mChildHelper.dispatchNestedFling(velocityX, velocityY, consumed);
}
#Override
public boolean dispatchNestedPreFling(float velocityX, float velocityY) {
return mChildHelper.dispatchNestedPreFling(velocityX, velocityY);
}
}
Declare NestedWebView instead of declaring WebView inside the NestedScrollView.For example
<com.nestedscrollwebviewexample.NestedWebView
android:id="#+id/nested_webview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#000000"
android:fillViewport="true"
android:focusable="true"
android:isScrollContainer="false"
android:visibility="visible"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
app:layout_scrollFlags="scroll|exitUntilCollapsed" />
Instead of declaring Webview you can initialize as NestedWebView inside your Activity
private NestedWebView mShopWebView;
mShopWebView = (NestedWebView) findViewById(R.id.url_load_webview);
Hope this serves the purpose.

I worked around this by adding a floating WebView over the screen at the same level of the hierarchy as the ScrollView and linked its position to the scroll value, then switched touch control with WebView.BringToFront and ScrollView.BringToFront

Snap HorizontalScrollView

I got the code below from here.
This code snaps the items of HorizontalScrollView. I tried a lot to implement this customView inside my layout but I am not able to figure out to how to attach my layout to it.
This example does add the views programmatically and calls them Features.
In XML I have done "my package name.view" but I cannot figure out how to call setFeatureItems so that my Views can be attached to it.
The snapping feature can be applied on RecyclerView easily by using SnapHelper but I haven't found anything for HorizontalScrollView.
public class HomeFeatureLayout extends HorizontalScrollView {
private static final int SWIPE_MIN_DISTANCE = 5;
private static final int SWIPE_THRESHOLD_VELOCITY = 300;
private ArrayList mItems = null;
private GestureDetector mGestureDetector;
private int mActiveFeature = 0;
public HomeFeatureLayout(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public HomeFeatureLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public HomeFeatureLayout(Context context) {
super(context);
}
public void setFeatureItems(ArrayList items){
LinearLayout internalWrapper = new LinearLayout(getContext());
internalWrapper.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
internalWrapper.setOrientation(LinearLayout.HORIZONTAL);
addView(internalWrapper);
this.mItems = items;
for(int i = 0; i< items.size();i++){
LinearLayout featureLayout = (LinearLayout) View.inflate(this.getContext(),R.layout.homefeature,null);
//...
//Create the view for each screen in the scroll view
//...
internalWrapper.addView(featureLayout);
}
setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
//If the user swipes
if (mGestureDetector.onTouchEvent(event)) {
return true;
}
else if(event.getAction() == MotionEvent.ACTION_UP || event.getAction() == MotionEvent.ACTION_CANCEL ){
int scrollX = getScrollX();
int featureWidth = v.getMeasuredWidth();
mActiveFeature = ((scrollX + (featureWidth/2))/featureWidth);
int scrollTo = mActiveFeature*featureWidth;
smoothScrollTo(scrollTo, 0);
return true;
}
else{
return false;
}
}
});
mGestureDetector = new GestureDetector(new MyGestureDetector());
}
class MyGestureDetector extends SimpleOnGestureListener {
#Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
try {
//right to left
if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
int featureWidth = getMeasuredWidth();
mActiveFeature = (mActiveFeature < (mItems.size() - 1))? mActiveFeature + 1:mItems.size() -1;
smoothScrollTo(mActiveFeature*featureWidth, 0);
return true;
}
//left to right
else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
int featureWidth = getMeasuredWidth();
mActiveFeature = (mActiveFeature > 0)? mActiveFeature - 1:0;
smoothScrollTo(mActiveFeature*featureWidth, 0);
return true;
}
} catch (Exception e) {
Log.e("Fling", "There was an error processing the Fling event:" + e.getMessage());
}
return false;
}
}
}

in your recycleview adapter you will have reference to HomeFeatureLayout there you can call
homeFeatureLayout.setFeatureItems(items);
EDIT
public void setFeatureItems(ArrayList items){
for(int i = 0; i< items.size();i++){
// here you need to provide layout of individual items in your horizontal scrollview
LinearLayout featureLayout = (LinearLayout) View.inflate(this.getContext(),R.layout.anyLayout,null);
//...
//display information here
//...
TextView title = (TextView)featureLayout.findviewById(R.id.title);
title.setText("view title "+item.get(i).getTitle());
ImageView image = (ImageView)featureLayout.findviewById(R.id.icon);
image.setResourceId(R.drawable.icon);
internalWrapper.addView(featureLayout);
}
}

EditText cursor visible even if the EditText is not editable

I need to introduce data in an EditText but i want to use an virtual keyboard, not the android keyboard. If I use setKeyListener(null) the cursor is invisible even after using setCursorVisible(true).
Is it possible to make an EditText where even if it isn't editable the cursor is visible ?
EDIT 2 :
I found an partial method to do that, but it's not working when i'm double taping the EditText.
I made an setOnClickListner() and an setOnLongClickListner() method for the EditText. In this methods I hide the Soft Input from the Window, also i use setTextIsSelectable(false). My only problem is that when I double tap the EditText the soft input keyboard shows and I dont know how to hide it, I tried to use android:windowSoftInputMode="stateAlwaysHidden" in manifest, but it doesn't work either.
EDIT :
Here is the code that I'm using at this moment for my base converter calculator.
public class MainActivity extends AppCompatActivity {
EditText number;
EditText base;
boolean baseB = false;
String numberS = "0";
String baseS = "10";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(activity_main);
//make the EditText for number and base not editable
number = (EditText) findViewById(R.id.number);
number.setKeyListener(null);
base = (EditText) findViewById(R.id.base);
base.setKeyListener(null);
//... more code here (changing fonts for each EditText and changing status bar color
}
// I have a function for each button all are the same
public void onClickBaseChange(View v) {
if (baseB) {
baseB = false;
// i use toasts at this moment to know when i'm on number or base field
Toast.makeText(this, "Number", Toast.LENGTH_SHORT).show();
} else {
baseB = true;
Toast.makeText(this, "Base", Toast.LENGTH_SHORT).show();
}
}
public void onClickB0(View v) {
if (numberS.length() > 0 && !numberS.equals("0") && !baseB) {
numberS += "0";
number = (EditText) findViewById(R.id.number);
number.setText(numberS, TextView.BufferType.EDITABLE);
number.setSelection(numberS.length());
} else {
if (Integer.valueOf(baseS) >= 1) {
baseS += "0";
base = (EditText) findViewById(R.id.base);
base.setText(baseS, TextView.BufferType.EDITABLE);
}
}
}
public void onClickB1(View v) {
if (numberS.equals("0")) {
numberS = "1";
} else {
numberS += "1";
}
number = (EditText) findViewById(R.id.number);
number.setText(numberS, TextView.BufferType.EDITABLE);
number.requestFocus();
number.setSelection(numberS.length());
}
And the xml looks like this :

In your xml you can give like this,
<[package name].KeypadlessKeypad
android:id="#+id/dialnumbertv"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#00000000"
android:cursorVisible="false"
android:ellipsize="start"
android:gravity="center"
android:inputType="phone"
android:singleLine="true"
android:textIsSelectable="true"
android:textSize="30sp"
android:textStyle="italic"
android:visibility="visible"/>
And in your fragment you can implement like this,
public void onViewCreated(final View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
mDialNumbertv = view.findViewById(R.id.dialnumbertv);
mDialNumbertv.setCursorVisible(false);
mDialNumbertv.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (!isDigitsEmpty()) {
mDialNumbertv.setCursorVisible(true);
}
}
});
mDialNumbertv.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
#Override
public void afterTextChanged(Editable s) {
if (isDigitsEmpty()) {
mDialNumbertv.setCursorVisible(false);
}
// updateDeleteButton();
}
});
mDialNumbertv.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
// Ref https://android.googlesource.com/platform/packages/apps/Contacts/+/39948dc7e34dc2041b801058dada28fedb80c388/src/com/android/contacts/dialpad/DialpadFragment.java
// Right now EditText does not show the "paste" option when cursor is not visible.
// To show that, make the cursor visible, and return false, letting the EditText
// show the option by itself.
mDialNumbertv.setCursorVisible(true);
return false;
}
});
mDialNumbertv.setOnEditTextActionListener(
new KeypadlessKeypad.OnEditTextActionListener() {
#Override
public void onPaste() {
// If some content pasted on mDialNumbertv
// we need to run some search on Contact and Price
String mobileNumber = mDialNumbertv.getText().toString();
if (TextUtils.isEmpty(mobileNumber)) {
return;
}
// updateContactName(mobileNumber);
}
});
}
private KeypadlessKeypad mDialNumbertv;
private boolean isDigitsEmpty() {
return mDialNumbertv.length() == 0;
}
private void setClickedDigit(final String digitToSet) {
if (!TextUtils.isEmpty(digitToSet)) {
char digit = digitToSet.charAt(0);
String mobileNumber = mDialNumbertv.getText() + digitToSet;
mDialNumbertv.getText().insert(mDialNumbertv.getSelectionStart(), digitToSet);
// If the cursor is at the end of the text we hide it.
final int length = mDialNumbertv.length();
if (length == mDialNumbertv.getSelectionStart() && length == mDialNumbertv.getSelectionEnd()) {
mDialNumbertv.setCursorVisible(false);
}
}
}

I wanted the same behavior which I achieved as follows -
Make a custom class that will override 2 methods of AppCompatEditText.
class CustomEditText(context: Context?, attrs: AttributeSet) : AppCompatEditText(context, attrs) {
override fun onCheckIsTextEditor(): Boolean {
return true
}
override fun isTextSelectable(): Boolean {
return true
}
}
In the XML file, create EditText using this custom view.
<com.ui.custom.CustomEditText
android:id="#+id/et_email"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:inputType="none"
android:focusable="true"
android:gravity="center"
android:focusableInTouchMode="true"/>
Now, just add onFocusChangeListener and set editText.setKeyListener = null.
binding.etEmail.onFocusChangeListener = OnFocusChangeListener { v, hasFocus ->
if (hasFocus) {
binding.etEmail.keyListener = null
}
}
You can add the same on onTouch if that is the requirement.
The main issue here is that onCheckIsTextEditor() of View class always returns false, which leads to cursor never blinking or being visible even if setCursorVisible(true) was called in code.
I hope it helps.

You can use edittext.setselection(0)
or
maybe you can request focus using requestfocus()

Are there additional buttons for ExoPlayer for Android?

Are there any additional libraries that contain button graphics for the Android ExoPlayer found here. There are the options for fast forward, rewind, play, pause and a few others but there are no options for a mute/unmute or fast forward 2x/4x/etc. I want those options as I build an alternative UI.

Change the Media Controller to provide the options that going to mute/unmute or fast forward. For adding these view(Buttons) in to the view of controller then for that customize the media controller. Check this also Custom Media Controller

Android: ClickableSpan in clickable TextView

I have a textview that can contain clickable links. When one of this links is clicked, I want to start an activity. This works fine, but it should also be possible to click the whole textview and start another activity.
So that's my current solution:
TextView tv = (TextView)findViewById(R.id.textview01);
Spannable span = Spannable.Factory.getInstance().newSpannable("test link span");
span.setSpan(new ClickableSpan() {
#Override
public void onClick(View v) {
Log.d("main", "link clicked");
Toast.makeText(Main.this, "link clicked", Toast.LENGTH_SHORT).show();
} }, 5, 9, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
tv.setText(span);
tv.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Log.d("main", "textview clicked");
Toast.makeText(Main.this, "textview clicked", Toast.LENGTH_SHORT).show();
}
});
tv.setMovementMethod(LinkMovementMethod.getInstance());
The problem is, that when I set an OnClickListener, everytime I click on a link first the listener for the whole textview and then the one for the ClickableSpan is called.
Is there a way to prevent android from calling the listener for the whole textview, when a link is clicked? Or to decide in the listener for the whole view, if a link was clicked or not?

Found a workaround that is quite straight forward. Define ClickableSpan on all the text areas that are not part of the links and handle the click on them as if the text view was clicked:
TextView tv = (TextView)findViewById(R.id.textview01);
Spannable span = Spannable.Factory.getInstance().newSpannable("test link span");
span.setSpan(new ClickableSpan() {
#Override
public void onClick(View v) {
Log.d("main", "link clicked");
Toast.makeText(Main.this, "link clicked", Toast.LENGTH_SHORT).show();
} }, 5, 9, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
// All the rest will have the same spannable.
ClickableSpan cs = new ClickableSpan() {
#Override
public void onClick(View v) {
Log.d("main", "textview clicked");
Toast.makeText(Main.this, "textview clicked", Toast.LENGTH_SHORT).show();
} };
// set the "test " spannable.
span.setSpan(cs, 0, 5, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
// set the " span" spannable
span.setSpan(cs, 6, span.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
tv.setText(span);
tv.setMovementMethod(LinkMovementMethod.getInstance());
Hope this helps (I know this thread is old, but in case anyone sees it now...).

This is a quite easy solution.. This worked for me
textView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ClassroomLog.log(TAG, "Textview Click listener ");
if (textView.getSelectionStart() == -1 && textView.getSelectionEnd() == -1) {
// do your code here this will only call if its not a hyperlink
}
}
});

Matthew suggested subclassing TextView and with that hint a came up with a rather ugly workaround. But it works:
I've created a "ClickPreventableTextView" which I use when I have clickablespans in a TextView that should be clickable as a whole.
In its onTouchEvent method this class calls the onTouchEvent method of MovementMethod before calling onTouchEvent on its base TextView class. So it is guaranted, that the Listener of the clickablespan will be invoked first. And I can prevent invoking the OnClickListener for the whole TextView
/**
* TextView that allows to insert clickablespans while whole textview is still clickable<br>
* If a click an a clickablespan occurs, click handler of whole textview will <b>not</b> be invoked
* In your span onclick handler you first have to check whether {#link ignoreSpannableClick} returns true, if so just return from click handler
* otherwise call {#link preventNextClick} and handle the click event
* #author Lukas
*
*/
public class ClickPreventableTextView extends TextView implements OnClickListener {
private boolean preventClick;
private OnClickListener clickListener;
private boolean ignoreSpannableClick;
public ClickPreventableTextView(Context context) {
super(context);
}
public ClickPreventableTextView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public ClickPreventableTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public boolean onTouchEvent(MotionEvent event) {
if (getMovementMethod() != null)
getMovementMethod().onTouchEvent(this, (Spannable)getText(), event);
this.ignoreSpannableClick = true;
boolean ret = super.onTouchEvent(event);
this.ignoreSpannableClick = false;
return ret;
}
/**
* Returns true if click event for a clickable span should be ignored
* #return true if click event should be ignored
*/
public boolean ignoreSpannableClick() {
return ignoreSpannableClick;
}
/**
* Call after handling click event for clickable span
*/
public void preventNextClick() {
preventClick = true;
}
#Override
public void setOnClickListener(OnClickListener listener) {
this.clickListener = listener;
super.setOnClickListener(this);
}
#Override
public void onClick(View v) {
if (preventClick) {
preventClick = false;
} else if (clickListener != null)
clickListener.onClick(v);
}
}
The listener for the clickable span now looks like that
span.setSpan(new ClickableSpan() {
#Override
public void onClick(View v) {
Log.d("main", "link clicked");
if (widget instanceof ClickPreventableTextView) {
if (((ClickPreventableTextView)widget).ignoreSpannableClick())
return;
((ClickPreventableTextView)widget).preventNextClick();
}
Toast.makeText(Main.this, "link clicked", Toast.LENGTH_SHORT).show();
} }, 5, 9, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
For me the main disadvantage is, that now getMovementMethod().onTouchEvent will be called twice (TextView calls that method in it's onTouchEvent method). I don't know if this has any side effects, atm it works as expected.

The code is work for me and that is from source code of LinkMovementMethod
tv.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
TextView tv = (TextView) v;
if (event.action == MotionEvent.ACTION_UP) {
int x = (int) event.getX();
int y = (int) event.getY();
Layout layout = tv.getLayout();
int line = layout.getLineForVertical(y);
int off = layout.getOffsetForHorizontal(line, x);
ClickableSpan[] link = contentSpan.getSpans(off, off, ClickableSpan.class);
if (link.length != 0) {
link[0].onClick(tv);
} else {
//do other click
}
}
return true;
}
});

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 :

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);

It's quite simple, you can cancell textview's pending intent about click in ClickableSpan callback
span.setSpan(new ClickableSpan() {
#Override
public void onClick(View v) {
tv.cancelPendingInputEvents() //here new line, textview will not receive click event
Log.d("main", "link clicked");
Toast.makeText(Main.this, "link clicked", Toast.LENGTH_SHORT).show();
} }, 5, 9, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
tv.setText(span);

I think that this involves subclassing TextView and changing its behavior, unfortunately. Have you thought about trying to put a background behind the TextView and attaching an onClickListener to it?

copy below function
private fun setClickableHighLightedText(
tv: TextView,
textToHighlight: String,
onClickListener: View.OnClickListener?
) {
val tvt = tv.text.toString()
var ofe = tvt.indexOf(textToHighlight, 0)
val clickableSpan = object : ClickableSpan() {
override fun onClick(textView: View) {
onClickListener?.onClick(textView)
}
override fun updateDrawState(ds: TextPaint) {
super.updateDrawState(ds)
//set color of the text
ds.color = getColor(R.color.black)
//draw underline base on true/false
ds.isUnderlineText = false
}
}
val wordToSpan = SpannableString(tv.text)
var ofs = 0
while (ofs < tvt.length && ofe != -1) {
ofe = tvt.indexOf(textToHighlight, ofs)
if (ofe == -1)
break
else {
wordToSpan.setSpan(
clickableSpan,
ofe,
ofe + textToHighlight.length,
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE
)
tv.setText(wordToSpan, TextView.BufferType.SPANNABLE)
tv.movementMethod = LinkMovementMethod.getInstance()
}
ofs = ofe + 1
}
}
use above function and
pass textview,clickble string
setClickableHighLightedText(tvTest,"test") {
showMessage("click")
}
