Android：具有多行文本的TextView不可点击/长按可点击

Question

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;
                }
            });

                    notifyDataSetChanged(); // position -1, newMessages.size() - position );
                    Toast.makeText(context, "Unsending the message", Toast.LENGTH_SHORT).show();
                }
            });

            messageRightBinding.unsendButtonRightHide.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    messageRightBinding.messageButtonHolder.setVisibility(View.GONE);
                }
            });

        }
    }

    private class ReceiveMessageHolder extends RecyclerView.ViewHolder{

        private MessageLeftBinding messageLeftBinding;

        ReceiveMessageHolder(MessageLeftBinding binding) {
            super(binding.getRoot());
            this.messageLeftBinding = binding;
        }

        public void bind(NewMessage newMessage, int position){

                    Picasso.get().load(contact.getProfilePicture()).resize(50, 50).
                            into(messageLeftBinding.messageLeftPp);

                if (newMessage.getTime() - lastTime >= 20000000) {
                    messageLeftBinding.conversationTime.setText(new Date(newMessage.getTime()).toString());
                    messageLeftBinding.conversationTime.setVisibility(View.VISIBLE);
                }

                messageLeftBinding.conversationTime.setVisibility(View.VISIBLE);
            }

            messageLeftBinding.timeTextView.setText(ContentUtils.getTime(newMessage.getTime()));
        }
    }
}

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.

Answer 1

尝试将文本放在相对布局中，然后将点击侦听器分配给相对布局

Answer 2

在您的TextView上设置android:clickable="true"和android:longClickable="true" 。

Answer 3

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.

Answer 4

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:clickable="true"
    android:focusable="true"
    android:longClickable="true">

            android:padding="6sp"
            android:text="@string/unsend" />
        <Button
            android:background="@drawable/rounded_whitebackground"
            android:backgroundTint="@color/dark_pink"

            android:fontFamily="@font/open_sans"
            android:text="@string/x" />
    </LinearLayout>
</RelativeLayout>

Sorry to everyone once again.
