Android 自定义ListView setOnItemClickListener

我有一个

列表视图

，显示时没有

扩展列表活动

。我想启用

setOnItemClickListener

。这是我在

onCreate

adapter = new CustomAdapter(this, MyDB);
        setListAdapter(adapter);

        mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View view, int position,
                                    long id) {

                Toast.makeText(getBaseContext(), "test", Toast.LENGTH_LONG).show();

            }

---

但是，

setOnItemClickListener

不工作

也许您在xml布局中设置了onClickListener-删除此选项

---

您可以为每个列表项视图指定

onClickListener

，而无需

ListView。setonimclicklister

如果您在内部使用可单击按钮，我认为最好的方法不是使用

AdapterView.onimclicklistener

，而是使用通常的

onClick

事件。

或者使用android:genderantfocusability=“blocksDescendants”我希望您的案例。

您可以在适配器上设置OnClickListener，如下所示-

public class DeviceList_Adapter extends BaseAdapter implements View.OnClickListener
{
/*************  CustomAdapter Constructor *****************/
public DeviceList_Adapter(Activity a, ArrayList d)
{

    /********** Take passed values **********/
    activity = a;
    data=d;

    /***********  Layout inflator to call external xml layout () ***********/
    inflater = (LayoutInflater)activity.
            getSystemService(Context.LAYOUT_INFLATER_SERVICE);

}

public int getCount() {

    if(data.size()<=0)
        return 1;
    return data.size();
}

public Object getItem(int position) {
    return position;
}

public long getItemId(int position) {
    return position;
}

public View getView(int position, View convertView, ViewGroup parent)
{

    View vi = convertView;
    ViewHolder holder;

    if(convertView==null){

        /****** Inflate listitem_device.xml file for each row ( Defined below ) *******/
        vi = inflater.inflate(R.layout.listitem_device, null);

        /******** Set Item Click Listner for LayoutInflater for each row *******/

        vi.setOnClickListener(new OnItemClickListener(position));
    }
    return vi;
}

@Override
public void onClick(View v) {
    Log.v("CustomAdapter", "=====Row button clicked=====");
}

/********* Called when Item click in ListView ************/
private class OnItemClickListener  implements View.OnClickListener {
    private int mPosition;

    OnItemClickListener(int position){
        mPosition = position;
    }

    @Override
    public void onClick(View arg0)
    {
        MainActivity mainActivity = (MainActivity)activity;

        /****  Call  onItemClick Method inside CustomListViewAndroidExample Class ( See Below )****/

        mainActivity.onItemClick(mPosition);
    }
}
}

公共类DeviceList\u适配器扩展BaseAdapter实现View.OnClickListener
{
/*************自定义适配器构造函数*****************/
公用设备列表适配器（活动a、阵列列表d）
{
/**********接受传递的值**********/
活动=a；
数据=d；
/***********布局充气器调用外部xml布局（）***********/
充气器=（充气器）活动。
getSystemService（上下文布局\充气机\服务）；
}
public int getCount（）{
如果（data.size（）你有什么错误吗？你的listView是如何创建的？里面有按钮之类的视图吗？没有错误，我就是拿不到吐司。试试`android:DegenantFocusability=“blocksDescendants”`Opiatefuchs，是的，里面有按钮
