问题：
RecyclerView项目中的按钮有时不会注册点击
姚和顺
我有一个RecyclerView列表，其中显示了一个包含一些文本视图和按钮的项目。我已经将每个项目的按钮链接到特定功能。碎片看起来像这样。
这两个按钮（红色和蓝色）根据用户的状态更改其功能。e、 g.当用户未被批准时，蓝色按钮将显示“激活帐户”，红色按钮将显示“删除请求”，每个按钮都有自己的功能。按钮的所有功能都按预期工作，但有一个小问题。当我点击这两个按钮中的一个时，它有时不会注册点击。我认为这可能与RecyclerView的滚动属性有关。有没有办法克服这个问题？我希望这些按钮能像普通按钮一样工作，当触摸按钮时，它将始终注册为按钮点击，而不是循环视图拖动。

class AccountViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
TextView text_name;
TextView text_username;
TextView text_status1; // Approved | Pending
TextView text_status2; // Admin
TextView text_status3; // Operator
Button button_left; // Deactivate | Remove Request
Button button_right; // Admin | Activate
private WeakReference<AccountListClickListener> listenerRef;
public AccountViewHolder(@NonNull View itemView, AccountListClickListener clickListener) {
super(itemView);
listenerRef = new WeakReference<>(clickListener);
text_name = itemView.findViewById(R.id.acc_name);
text_username = itemView.findViewById(R.id.acc_username);
text_status1 = itemView.findViewById(R.id.acc_status);
text_status2 = itemView.findViewById(R.id.acc_status2);
text_status3 = itemView.findViewById(R.id.acc_status3);
button_left = itemView.findViewById(R.id.button_left);
button_right = itemView.findViewById(R.id.button_right);
button_left.setOnClickListener(this);
button_right.setOnClickListener(this);
}
@Override
public void onClick(View view) {
if (view.getId() == button_left.getId())
listenerRef.get().leftButtonClick(getAdapterPosition(), button_left.getText().toString(), text_username.getText().toString().substring(10));
if (view.getId() == button_right.getId())
listenerRef.get().rightButtonClick(getAdapterPosition(), button_right.getText().toString(), text_username.getText().toString().substring(10));
}
}

我解决了！显然，我有一个以固定间隔运行的计时器线程，它调用一个函数来填充卡片，并根据选择的无线电按钮过滤器过滤项目。计时器每100毫秒执行一次该函数来更新项目适配器，这没有给系统足够的时间来注册按钮按下。将计时器间隔更改为更长的持续时间解决了问题。
这是有意义的，因为当我触摸按钮超过100毫秒时，系统将不再识别我触摸了原始按钮，因为它已经填充了一组新的视图，最终，我触摸的按钮现在不见了，还有它的点击功能。
