Call Custom Dialog In Adapter Class

I have created a simple Custom dialog class and I want to display it after clicking on a row in RecycleView. My dialog class looks: public class AddToQueueDialog extends Dialog imp

Solution 1:

Just pass the context of your current Activity to your Adapter class and use it when you are creating an instance of AddToQueueDialog.

For example:

MainActivity.java

publicclassMainActivityextendsAppCompatActivity {

    Context mContext;

    // Views
    RecyclerView mRecyclerView;

    // Values
    List<Recipe> mRecipeList;

    // Adapter
    RecipeAdapter mAdapter;

    @OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        mContext = this;

        // Views
        mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view);

        .................
        ..........................

        // Values
        mRecipeList = newArrayList<Recipe>();

        // Adapter
        mAdapter = newRecipeAdapter(mContext, mRecipeList);

        // Set adapter to RecyclerView
        mRecyclerView.setAdapter(mAdapter);

        .................
        ..........................
   }
}  

RecipeAdapter.java

publicclassRecipeAdapterextendsRecyclerView.Adapter<RecipeAdapter.ViewHolder> {

    Context mContext;
    LayoutInflater mInflater;

    // List
    List<Recipe> mRecipeList;

    publicGroupListAdapter(Context context, List<Recipe> listRecipe) {

        this.mContext = context;
        this.mRecipeList = listRecipe;

        mInflater = LayoutInflater.from(mContext);
    }

    .....................
    ...............................

    publicclassViewHolderextendsRecyclerView.ViewHolder implementsView.OnClickListener {       

        publicViewHolder(View itemView) {
            super(itemView);
            info = (TextView) itemView.findViewById(R.id.textView);
            favorite = (Button) itemView.findViewById(R.id.addToFav);

            favorite.setOnClickListener(this);
            info.setOnClickListener(this);
        }

        @OverridepublicvoidonClick(View v) {
            if(v.getId() == info.getId()){
                AddToQueueDialogaddToQueueDialog=newAddToQueueDialog(mContext);
                addToQueueDialog.show();
            }
       }
    }

    ............
    ......................
}

Hope this will help~

Solution 2:

classMyAdapterextendsRecyclerView.Adapter<VH> {

  // set this field through setter or constructorprivate OnClickListener mMyOnClickListener;

  ...

  voidonBindViewHolder(..., VH viewHolder) {
    viewHolder.rootView.setOnClickListener(() -> {
       if (mOnClickListener != null) {
          mOnClickListener.onClick();
       }
     });
  }

  staticclassVHextendsViewHolder {
    View rootView;

    VH(View itemView) {
      super(itemView);
      rootView = itemView;
    }
  }
}

classMainActivityextendsAppCompatActivity {

  ...

  voidsetUpRecyclerView(){
    ...
    adapter.setMyOnClickListener(() -> {
       newDialog(MainActivity.this).show();
     });
  }
}
