Question

我正在尝试，但是当我同时实现这两个时，ViewHolder无法达到这些。可能吗？我的代码：

public final class SomeViewHolder extends RecyclerView.ViewHolder
    implements View.OnClickListener, View.OnLongClickListener {

    public final AestheticTextView mName;
    public final AestheticTextView mNumber;

    public SomeViewHolder(View itemView) {
        super(itemView);
        mName = (AestheticTextView) itemView.findViewById(android.R.id.title);
        mNumber = (AestheticTextView) itemView.findViewById(android.R.id.summary);

        itemView.setOnClickListener(this);
        itemView.setOnLongClickListener(this);
    }

    @Override
    public void onClick(View view) {
        // doesn't run
    }

    @Override
    public boolean onLongClick(View view) {
        // doesn't run
    }
}

如果我删除其中一个监听器，如下所示，它可以正常工作。

public final class SomeViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

    public final AestheticTextView mName;
    public final AestheticTextView mNumber;

    public SomeViewHolder(View itemView) {
        super(itemView);
        mName = (AestheticTextView) itemView.findViewById(android.R.id.title);
        mNumber = (AestheticTextView) itemView.findViewById(android.R.id.summary);

        itemView.setOnClickListener(this);
    }

    @Override
    public void onClick(View view) {
        // run properly
    }
}

创建一个绑定方法或任何你想要调用它的方法。

public void bind(ModelClass model, MyInterface listener) {

itemView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
//Create your own interface and add arguments based on your needs
                    listener.itemClicked(view);
                }
            });

itemView.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
    //Create your own interface and add arguments based on your needs
                        listener.itemLongClicked(view);
                    }
                });
}

在onBindViewHolder()
上

holder.bind(item.get(position), listener);

宣布你的Adapter
时

    adapter = new MyAdapter(item, new OnItemClick() {
        @Override
        public void itemClicked(View view, ModelClass model) {
            //event
        }
        @Override
        public void itemLongClicked(View view, ModelClass model) {
            return true;
        }
    });

如何在单个视图中实现onClickListener和onLongClickListener？
