listview onitemclicklistener用於自定義布局

Question

我有一個listview ：

   <ListView
        android:clickable="true"
        android:id="@android:id/list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >
    </ListView>

里面的元素是這樣的：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal" >




    <TextView
        android:id="@+id/textview_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="0.76"
        android:text="Choose"
        android:clickable="true" />


    <EditText
        android:id="@+id/edittext_share"
        android:layout_width="50dp"
        android:layout_height="wrap_content"
        android:layout_weight="0.12"
        android:ems="10"
        android:hint="share"
        android:inputType="number" >

        <requestFocus />
    </EditText>


    <EditText
        android:id="@+id/edittext_spent"
        android:layout_width="50dp"
        android:layout_height="wrap_content"
        android:layout_weight="0.11"
        android:ems="10"
        android:hint="spent"
        android:inputType="number" />

</LinearLayout>

我希望當我點擊TextView ，會發生一些事情。 我通過getListView()設置了setOnItemClickListener但它不起作用。

    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
    // TODO Auto-generated method stub
    Toast.makeText(this,"clicked id="+arg2, Toast.LENGTH_SHORT).show();
}

和

        ListView lv = getListView();
    lv.setOnItemClickListener(this);

我該怎么做才能使textview變得復雜？

編輯 ：我的適配器代碼：

    private class PeopleListAdapter extends BaseAdapter {
    private LayoutInflater mInflater;
    public Cursor cursor;
    public ArrayList<PersonInfo> peopleList;
    public ArrayList<PersonInfo> unsavedPeopleList;

    public PeopleListAdapter(Context context, Cursor cursor) {
        // Cache the LayoutInflate to avoid asking for a new one each time.
        mInflater = LayoutInflater.from(context);
        this.cursor = cursor;
        peopleList = new ArrayList<PersonInfo>(cursor.getCount());
    }

    public PeopleListAdapter(Context context, Cursor cursor,
            ArrayList<PersonInfo> unsavedList) {
        this(context, cursor);
        this.unsavedPeopleList = unsavedList;
    }

    /**
     * The number of items in the list is determined by the number of
     * speeches in our array.
     *

    public int getCount() {
        return peopleList.size() + unsavedPeopleList.size();
    }

    /**

     * sufficent to get at the data. If we were using a more complex data

     *

    /**

    public View getView(int position, View convertView, ViewGroup parent) {
        // A ViewHolder keeps references to children views to avoid
        // unneccessary calls

        ViewHolder holder;

        // When convertView is not null, we can reuse it directly, there is
        // no need
        // to reinflate it. We only inflate a new View when the convertView
        // supplied
        // by ListView is null.
        if (convertView == null) {
            convertView = mInflater.inflate(R.layout.list_item_person_info,
                    null);

            // Creates a ViewHolder and store references to the two children
            // views
            // we want to bind data to.
            holder = new ViewHolder();
            holder.name = (TextView) convertView

        } else {
            // Get the ViewHolder back to get fast access to the TextView
            // and the ImageView.
            holder = (ViewHolder) convertView.getTag();
        }

        // Bind the data efficiently with the holder.

Answer 1

您需要在getView（）函數中將Click偵聽器偵聽器設置為適配器中的TextView ......

看到這個鏈接

        private class PeopleListAdapter extends BaseAdapter implements
OnClickListener {

     ..............................
      ............................


public View getView(int position, View convertView, ViewGroup parent) {
       
             ......................
           .....................
        holder.name.setText(p.name);
        //holder.name.setTag(p.lookupUri);
        holder.share.setText(p.share + "");
        holder.spent.setText(p.spent + "");

        holder.name.setOnClickListener(this);
       holder.name.setTag(position);



        return convertView;
    }

     @Override
    public void onClick(View v) {
        Log.d("Sample", "Clicked on tag: " + v.getTag());
        ////get PersonInfo using getPersonInfo(position) 
    }

Answer 2

如果您正在使用ListActicvity，那么有一個名為onListItemClick()的默認方法。 您必須在ListActivity中覆蓋此方法，

protected void onListItemClick(android.widget.ListView l, android.view.View v, int position, long id) {

        //find which item is clicked using the view object
    };

Answer 3

在ClickListener上設置在getListView（）方法TextView中。

謝謝。

Answer 4

根據我的理解，這就是你想要的：你希望ListView中的TextView可以點擊執行基於它的一些操作，並且你在ListView中有自定義布局的項目

所以：setOnItemClickListener 將無法工作，因為它為ListVIew中的整個項添加了一個偵聽器，而不是其中的元素。

為此，您可以執行此操作：向ListView內部的元素添加標記，並在默認情況下為您提供位置的getView方法內部，使用該標記並使用getTag（）方法使用標記可以區分所點擊的內容在xml中你可以簡單地聲明onClick（）並提供它的定義
