Android: TextView having text of more than one line is not clickable/long clickable

When TextView containing chat message is having content more than accommodatable in one line, the text view stops listening for clicks and long clicks. I tried to listen same events on the parent item of TextView, but it's not working there as well.
This is the code:
<TextView
android:id="#+id/message_text_view"
android:background="#drawable/bubble_right"
android:clickable="true"
android:focusable="true"
android:longClickable="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:fontFamily="#font/open_sans"
android:layout_marginStart="17dp"
android:layout_marginEnd="5dp"
android:paddingTop="8sp"
android:paddingBottom="8sp"
android:paddingStart="20sp"
android:paddingEnd="20sp"
android:text="#string/hello"
android:textColor="#color/white"
android:textSize="16sp" />
Java code:
messageRightBinding.messageTextView.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
messageRightBinding.messageTextView.setVisibility(View.VISIBLE);
return true;
}
});

Screenshot:
Here the Unsend and X button come on long click, but that works only for one liner messages.
Any help or suggestion will be appreciated and I will be very thankful.

try putting your text in a relativelayout and give the click listener to the relative layout

Set android:clickable="true" and android:longClickable="true" on your TextView.

In your SendMessageHolder class, replace
messageRightBinding.messageHolder.setOnLongClickListener
with
itemView.setOnLongClickListener
You shouldn't set a long-click listener on a child View in a RecyclerView.

Sorry everyone for wasting your time and frying your heads for a problem which was not there actually. Those two buttons "Unsend" and "X" were not visible because when the TextView got content in length more than a line, it's was using the full width of screen leaving no space for other things. Hence even when the button's state was visible the buttons were not there in view port. Causing this so lengthy discussion and a misleading question title.
Finally this worked for me:
<LinearLayout
android:layout_width="match_parent"
android:clickable="true"
android:focusable="true"
android:longClickable="true"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="end|center_vertical"
android:padding="4dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"

Listview returning the wrong postion with BaseSwipeAdapter

I am using a listview with swipelayout (daimajia library) and my listview is scrolling...
My problem is when I swipe listview item and click on button in it ,it returns me wrong position..
Do you have any idea of how to solve this??
This is my adapter
public View generateView(final int position, final ViewGroup parent) {
View v =
LayoutInflater.from(parent.getContext()).inflate(R.layout.ledger_layout, null);
SwipeLayout swipeLayout = (SwipeLayout) v.findViewById(getSwipeLayoutResourceId(position));
swipeLayout.addSwipeListener(new SimpleSwipeListener() {
#Override
public void onOpen(SwipeLayout layout) {
}
});
swipeLayout.setOnDoubleClickListener(new
SwipeLayout.DoubleClickListener() {
#Override
public void onDoubleClick(SwipeLayout layout, boolean surface) {
Toast.makeText(context, "DoubleClick",
Toast.LENGTH_SHORT).show();
}
});
return v;
}

I think your implementation of getView method is messy. Try this.
ListAdapter Java class.

}

viewHolder.swipeLayout = view.findViewById(R.id.swipe);
viewHolder.textView = view.findViewById(R.id.text_data);
viewHolder.delete = view.findViewById(R.id.delete);
view.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) view.getTag();
}
viewHolder.textView.setText(String.valueOf("Swipe Layout : " + position));
viewHolder.swipeLayout.addSwipeListener(new SimpleSwipeListener() {
#Override
public void onOpen(SwipeLayout layout) {
Toast.makeText(mContext, "onOpen : " + position,

It's been a long time but I had the same issue. It took hours to solve the problem but the solution is here. This WARNING is from the daimajia's wiki.
ATTENTION: Never bind listeners or fill values in generateView. Just generate the view and do everything else in fillValues (e.g using your holder class) See issues #14 and #17
You can find detailed solution here : Solution to your position problem from daimajia's wiki
And sample code is like this :
//ATTENTION: Never bind listener or fill values in generateView.
// You have to do that in fillValues method.
#Override
public View generateView(int position, ViewGroup parent) {
return LayoutInflater.from(mContext).inflate(R.layout.grid_item, null);
}
#Override
public void fillValues(int position, View convertView) {
TextView t = (TextView)convertView.findViewById(R.id.position);
t.setText((position + 1 )+".");
}
You should do everything in fillValues() function. position value here is always right.
Just follow this rule and everything will be fine with your Swipe ListView.

GridView item looks not as expected - Android

I try to use a GridView object in a specific fragment in my app.
I created a layout file for the grid item and in the layout editor, the preview image looks good, as expected.
The problem arises when I run the app in my emulator. The whole item layout gets shrinked and the image I put in the middle suddenly jumps to the top of the layout.
Screenshot of the layout editor:

This worked for me, You can try...
`<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:padding="5dp" >
<GridView
android:id="#+id/gridview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:columnWidth="100dp"
android:gravity="center"
android:horizontalSpacing="10dp"
android:numColumns="3"
android:stretchMode="spacingWidthUniform"
android:verticalSpacing="10dp" />
`
If this don't work you can also try to use android:stretchMode="columnWidth"

If listview having same data then first row should be updated in android

I am using two ListViews (List1 has data and List2 is empty).
The user can enter a name as input and if List1 contains name and the add Button is pressed then marks should be decreased by 1 and both the ListViews should be updated.
Example:
If List1 has 10 marks and a name is entered then List1 should have marks set to 9 and List2 should have marks set to 1.
If the list1 has same names then index with first position name should be updated. Now both the values are updated with same name.
If we did this 10 times then List1 names should be removed and List2 has marks set to 10.
Example 2:
Suppose List1 has marks set to 8 and List2 marks set to 2. If the sub button is pressed then both should lists should be added. At this point, List2 should be deleted and List1 should have total marks as 10.
Below is the logic I have used however it is not working it is updating multiple rows with same names.
