Recyclerview поддерживает щелкнув выделенный элемент - Android

Question

У меня есть Recyclerview. как этот

Когда пользователь нажимает на строку, в которой конкретная строка будет получить выделенный с основным цветом, но когда пользователь берет палец его вернуться к прозрачному.

Но то, что я хочу, я хочу, чтобы строка последнего щелчка была подсвечена даже после того, как пользователь вытащил палец.

Answer 1

Первый экземпляр объекта selectedItems в вашем конструкторе, как показано ниже.

Затем создайте вызов метода selectLastItem() или любым другим именем, как показано ниже.

public void selectLastItem(int pos){ 
     selectedItems.clear(); 
     selectedItems.put(pos, true); 
     notifyDataSetChanged(); 
} 

А затем измените метод onBindViewHolder(), как показано ниже.

@Override 
public void onBindViewHolder(MyViewHolder holder, int position) { 
     CompanyProfileData CPData = companyProfileDataList.get(position); 
     holder.comName.setText(CPData.getComName()); 
     holder.hdName.setText(CPData.gethdName()); 
     holder.itemView.setBackgroundColor(selectedItems.get(position, false) ? ResourcesCompat.getColor(holder.itemView.getResources(), R.color.colorPrimary, null) : Color.TRANSPARENT); 
} 

Наконец, вызовите метод selectLastItem в onClick(), как показано ниже.

@Override 
public void onClick(View v) { 
     selectLastItem(getAdapterPosition()); 
} 

Я думаю, что это решит вашу проблему. Спасибо ..

Answer 2

Внутри общественного MyViewHolder вашего адаптера (View Вид)
написать это:

comName.setOnTouchListener(new OnTouchListener() { 

       @Override 
       public boolean onTouch(View v, MotionEvent event) { 
        comName.setPressed(true); 
        return true; 
       } 
      });
