Question

好吧，我有一个持有人，拿着一堆除了开关之外不会改变的元素（显然）。

我减少了代码，因为它更易于阅读，我认为这将允许我在日志中看到交换机的状态被更改（这是从适配器动态生成的）。

public View getView(final int position, View convertView, ViewGroup parent) {
    final ViewHolder holder;
        holder = new ViewHolder();
        holder.communicationfilter = (Switch)convertView.findViewById(R.id.communicationfilter);

    holder.communicationfilter.setChecked(!kid.isBlocked());
    holder.communicationfilter.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        Log.v(LOG_TAG, "Switch State="+isChecked);
    }               
    });
    convertView.setTag(holder);
    return convertView;
  }

Answer 1

请将Checked changed方法修改为

if(isChecked){
Log.v(LOG_TAG, "Switch State="+isChecked);
}else{
Log.v(LOG_TAG, "Switch State="+isChecked);
}

希望它有效......

Answer 2

这解决了它，希望它可以帮助那些遇到同样问题的人。

holder.communicationfilter.setOnCheckedChangeListener(new OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(CompoundButton buttonView,
    boolean isChecked) {
        if (isChecked) {
            Toast.makeText(mContext, "The switch is ON",Toast.LENGTH_SHORT).show();
            Log.i(LOG_TAG,"switch checked for" + holder.nameTxtView);
        } else {    
            Toast.makeText(mContext,"The switch is OFF", Toast.LENGTH_SHORT).show();
            Log.i(LOG_TAG,"switch unchecked" + holder.nameTxtView);
        }

        }
        });

ViewHolder持有android.widget.Switch，Switch没有响应监听器
