为什么我的ListView永远不会调用onItemClick？ [英] why my ListView never calls onItemClick?

问题描述

我真的搜查谷歌，栈溢出了很多，发现这一点：<一href=\"http://stackoverflow.com/questions/5551042/onitemclicklistener-not-working-in-listview-android\">OnItemCLickListener在列表视图ANDROID 不工作。但是，似乎阳光的回答并不适用于我的情况。其他的答案都是类似的。

我曾尝试以下方法：

添加机器人：可聚焦=FALSE我的列表项XML

添加 TextView.setFocusable（假）和 TextView.setClickable（假）在ViewHolder

使用如在上述链接中描述的XML

但他们没有工作。

下面是我的XML和Java code：

list_item.xml：

 ＆LT;？XML版本=1.0编码=UTF-8＆GT？;＆LT; LinearLayout中的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android
机器人：layout_width =match_parent
机器人：layout_height =WRAP_CONTENT
机器人：baselineAligned =假
机器人：descendantFocusability =blocksDescendants
机器人：可聚焦=假
机器人：paddingTop =2DP
机器人：重力=center_vertical＆GT;＆LT;的TextView
    机器人：ID =@ + ID / ninegrid_number_list_choice
    机器人：layout_width =match_parent
    机器人：layout_height =WRAP_CONTENT
    机器人：TEXTSIZE =@扪/ ninegrid_number_listchoice_text_size
    机器人：比重=中心
    ＆GT;
＆LT; / TextView的＆GT;
＆LT; / LinearLayout中＆GT;
 

getView INT列表adapter.java：

  @覆盖
    公共查看getView（INT位置，查看convertView，最终的ViewGroup父）{
        ViewHolder持有人;
        如果（convertView == NULL）{
            convertView = mInflater.inflate（R.layout.list_item，NULL）;
            持有人=新ViewHolder（）;
            holder.mTextView =（TextView中）convertView.findViewById（R.id.ninegrid_number_list_choice）;
            holder.mTextView.setFocusable（假）;
            holder.mTextView.setClickable（假）;
            convertView.setTag（保持器）;
        }其他{
            支架=（ViewHolder）convertView.getTag（）;
        }        holder.mTextView.setText（mList.get（位置））;
        holder.mTextView.setTextColor（mTextColor）;
        holder.mTextView.setFocusable（假）;
        holder.mTextView.setClickable（假）;
        返回convertView;
    }
 

编辑：
在我的活动：

  listchoice.setDescendantFocusability（ViewGroup.FOCUS_BLOCK_DESCENDANTS）;
 listChoice.setOnItemClickListener（新OnItemClickListener（）{
 @覆盖
 公共无效onItemClick（适配器视图＆LT;＆GT;为arg0，ARG1观，诠释ARG2，
     长ARG3）{      Log.v（标签，自卫队）;
 }
 }）;

I have really searched a lot on google, stack overflow , and found this : OnItemCLickListener not working in listview ANDROID. But seems sunshine's answer not works for my case. Other answers are all similar ones.

I have tried the following approaches:

add android:focusable="false" to my list item xml

add TextView.setFocusable(false) and TextView.setClickable(false) in ViewHolder

using the xml as described in the above link.

But none of them work.

Here's my xml and java code:

list_item.xml:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:baselineAligned="false"
android:descendantFocusability="blocksDescendants"
android:focusable="false"
android:paddingTop="2dp"
android:gravity="center_vertical" >

<TextView
    android:id="@+id/ninegrid_number_list_choice"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textSize="@dimen/ninegrid_number_listchoice_text_size"
    android:gravity="center"
    >
</TextView>
</LinearLayout>

getView int list adapter.java:

@Override
    public View getView(int position, View convertView, final ViewGroup parent) {
        ViewHolder holder;
        if (convertView == null ) {
            convertView = mInflater.inflate(R.layout.list_item, null);
            holder = new ViewHolder();
            holder.mTextView = (TextView)convertView.findViewById(R.id.ninegrid_number_list_choice);
            holder.mTextView.setFocusable(false);
            holder.mTextView.setClickable(false);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder)convertView.getTag();
        }

        holder.mTextView.setText(mList.get(position));
        holder.mTextView.setTextColor(mTextColor);
        holder.mTextView.setFocusable(false);
        holder.mTextView.setClickable(false);
        return convertView;
    }

Edit: in my activity:

 listchoice.setDescendantFocusability(ViewGroup.FOCUS_BLOCK_DESCENDANTS);
 listChoice.setOnItemClickListener(new OnItemClickListener() {
 @Override
 public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
     long arg3) {

      Log.v(tag, "sdf");
 }
 });
