Save, Share & Favorite Imageview в recyclerview

Question

Этот код содержит кнопку совместного доступа, кнопку загрузки и кнопку favourate.

до сих пор его правильная работа с кнопкой favourate, если я удалю метод onClick из ViewHolder. Я хочу реализовать кнопку совместного использования/сохранения onClick share/загрузить изображение в ImageView в recyclerview. Просьба игнорировать грамматические ошибки

Это моя карточка.

Вот MainActivity.Java

import android.os.Bundle; 
import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentManager; 
import android.support.v7.app.AppCompatActivity; 

public class MainActivity extends AppCompatActivity { 


    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     FragmentManager fm = getSupportFragmentManager(); 
     Fragment fragment = fm.findFragmentById(R.id.fragmentContainer); 

     if (fragment == null) { 
      fragment = new CardFragment(); 
      ; 
      fm.beginTransaction() 
        .add(R.id.fragmentContainer, fragment) 
        .commit(); 


     } 



    } 
} 

Answer 1

Создать свой ViewHolder Constructor Как это

public MyViewHolder(View v,Activity activity) { 
    super(v); 
this.activity = activity 
/////Remaining code 

Теперь вы можете получить контекст деятельности в классе viewholder. Надеюсь, это поможет вам!
