android listview

ListView setOnItemClickListener 添加按钮时不起作用

我有一个列表视图，每行上有文本和按钮，列表视图 setOnItemClickListener// 不起作用。是否有可能处理项目按下，然后单击不同的按钮/物品点击您需要调用 ActivityA 然后单击“只需调用”点击 ActivityB/. 有人有一个解决方案

private ArrayList<string> userIDArr = null;

 private ArrayList<string> userNameArr = null;

 private DatabaseHelper dbHelper = null;

 private ListView userListView=null; 





 public void onCreate/Bundle savedInstanceState/ 

 {

 super.onCreate/savedInstanceState/; 

 setContentView/R.layout.list_view/; 

 dbHelper = new DatabaseHelper/this.getApplicationContext///; 

 Map<string,arraylist<string>&gt; displayMap = dbHelper.getUserListToDisplay//;

 userIDArr = displayMap.get/"UserID"/;

 userNameArr = displayMap.get/"FirstName1"/; 





 userListView = /ListView/ findViewById/R.id.listView2/;

 userListView.setAdapter/new UserListAdapter/this,userIDArr//;





 userListView.setOnItemClickListener/new AdapterView.OnItemClickListener// {

 @Override

 public void onItemClick/AdapterView<? > arg0, View arg1, int position, long arg3/ {



 Toast.makeText/usersListActivity.this,

 "Item in position " + position + " clicked", Toast.LENGTH_LONG/.show//;

 }

 }/;

 }





 public class UserListAdapter extends ArrayAdapter<string>

 {

 Activity context;

 public UserListAdapter/Activity context, ArrayList<string> names/ {

 super/context, R.layout.list_item, names/;

 this.context = context;

 }

 private class ViewHolder {

 public TextView UserNameAndID;

 public TextView Description;

 public Button UploadBtn;

 }



 @Override

 public View getView/int position, View convertView, ViewGroup parent/ {

 ViewHolder holder;

 View rowView = convertView;

 if /rowView == null/ {

 LayoutInflater inflater = context.getLayoutInflater//;

 rowView = inflater.inflate/R.layout.list_item, null, true/;

 holder = new ViewHolder//;

 holder.UserNameAndID = /TextView/ rowView.findViewById/R.id.User_detailsTxt/;

 holder.Description = /TextView/ rowView.findViewById/R.id.User_status/;

 holder.UploadBtn = /Button/ rowView.findViewById/R.id.uploadbutton/;

 holder.UploadBtn.setOnClickListener/new View.OnClickListener// { 



 public void onClick/View v/ { 

 Toast.makeText/usersListActivity.this," Button clicked",Toast.LENGTH_SHORT/.show//;

 } 

 }/; 

 rowView.setTag/holder/;

 } else {

 holder = /ViewHolder/ rowView.getTag//;

 }

 String s = userNameArr.get/position/+","+userIDArr.get/position/;

 holder.UserNameAndID.setText/s/;

 holder.Description.setText/"U r in middle"/;

 return rowView;

 }

 }

}`

</string></string></string,arraylist<string></string></string>

尝试自定义按钮。 /或者您想要处理的任何其他表示点击列表项/ 通过以下方式：

android:focusable="false"

android:focusableInTouchMode="false"

有时，列表仍然无法强制侦听器单击。在这种情况下，您可能必须添加另一个属性。

android:descendantFocusability="blocksDescendants"

此属性必须添加到最顶层布局 XML, 你在哪里提供元素 ListView.

如果您有活动视图/在您的列表中的聚焦视图，它将关闭

onItemClickListener

... 您可以尝试通过添加：

android:focusable="false"

对于任何类型，通常侧重于。

面团是要添加的

Listener

对所有人来说

rowView

, 所以K.

Button

里面

Adapter

.
类似的东西。

public class MyAdapter extends BaseAdapter implements View.OnClickListener{



 @Override

 public View getView/int position, View convertView, ViewGroup parent/

 {

 View rowView = convertView;

 if/rowView == null/

 {

 //intialize rowView, and set onclick listener only once.

 rowView = someIntilizationMehhodOrInflatorMethod//;

 //add listener to the button also and also to the row view

 rowView.setOnClickListener/this/;

 }

 //all your inflation and setting values goes here and at the end,

 //set position as tag to get the correct position, rather buggy one.

 rowView.setTag/String.valueOf/position//;





 return rowView;

 }

 public void onClick/View v/

 {

 //now get the tag of View v and convert it to integer.

 int pos = Integer.parseInt/v.getTag//.toString///;

 Toast.makeText/context,"Item in position " + pos + " clicked",Toast.LENGTH_LONG/.show//;

 }

}

尝试设置

setClickable/false/

对于每一个人

Button

ImageButton

等等

View

通过以下方式：

view.setClickable/false/;

button.setClickable/false/;

imagebutton.setClickable/false/;

此外，您必须添加

android:descendantFocusability="blocksDescendants"

到主要的一个 /第一级/ 市场

添加

ImageView

并授予倾听者

setOnItemClcik

, 这将罚款。

public View getView/final int position, View convertView, ViewGroup parent/ {

 MyViewHolder mViewHolder;

 if/convertView == null/ {

 convertView = inflater.inflate/R.layout.youtubesearchrow, null/;

 mViewHolder = new MyViewHolder//;

 mViewHolder.alarm = /ImageView/convertView.findViewById/R.id.alarm/;

 convertView.setTag/mViewHolder/;

 } else {

 mViewHolder = /MyViewHolder/ convertView.getTag//;

 }



 mViewHolder.tvTitle = detail/convertView, R.id.tvTitle, 

 // mViewHolder.tvDesc = detail/convertView, R.id.tvDesc, 

 mViewHolder.ivIcon = detail_image/convertView, R.id.ivIcon, 



 mViewHolder.alarm.setOnClickListener/new OnClickListener// {



 @Override

 public void onClick/View v/ {

 // TODO Auto-generated method stub

 }

 }/;



 return convertView;

}

我也得到了同样的错误。如果列表布局上有任何按钮，请将其替换为

TextView

, IE

ImageButton

上

ImageView

. 供参考，我的代码是：

private Activity activity;

private LayoutInflater inflater;



private List<itemlist> itemListsItems;



private Bookmark_SharedPref pref;



ImageLoader imageLoader = AppController.getInstance//.getImageLoader//;



public CustomListAdapter_Item/Activity activity,List<itemlist> itemListsItems/{

 this.activity=activity;

 this.itemListsItems=itemListsItems;

 pref = new Bookmark_SharedPref/activity/;

}





@Override

public int getCount// {

 return itemListsItems.size//;

}



@Override

public Object getItem/int position/ {

 return itemListsItems.get/position/;

}



@Override

public long getItemId/int position/ {

 return position;

}



@Override

public View getView/final int position, View convertView, ViewGroup parent/ {



 View v = convertView;

 ViewHolder holder;



 if/inflater == null/{

 inflater = /LayoutInflater/activity.getSystemService/Context.LAYOUT_INFLATER_SERVICE/;

 }

 if/convertView == null/{

 convertView = inflater.inflate/R.layout.item_layout,null/;



 holder = new ViewHolder//;

 convertView.setTag/holder/;

 }

 else{

 holder = /ViewHolder/convertView.getTag//;

 }





 if/imageLoader == null/{

 imageLoader = AppController.getInstance//.getImageLoader//;

 }









 holder.img = /NetworkImageView/convertView.findViewById/R.id.item_image/;

 holder.Title = /TextView/convertView.findViewById/R.id.item_title/;

 holder.Cat = /TextView/convertView.findViewById/R.id.item_category/;



 holder.id = /TextView/convertView.findViewById/R.id.itemid/;



 holder.Desc = /TextView/convertView.findViewById/R.id.item_description/;



 holder.book = /ImageView/convertView.findViewById/R.id.bookmark_star/;







 // getting blog data or the row

 ItemList il = itemListsItems.get/position/;



 //setting image

 holder.img.setImageUrl/il.getImageUrl//, imageLoader/;



 // setting title

 holder.Title.setText/il.getTitle///;



 //setting category

 holder.Cat.setText/il.getCategory///;





 //setting blog id

 holder.id.setText/il.getId///;



 //setting description

 holder.Desc.setText/il.getDescription///;



 //bookmarking the post

 holder.book.setOnClickListener/new View.OnClickListener// {

 @Override

 public void onClick/View v/ {



 itemListsItems.get/position/.isFav = !itemListsItems.get/position/.isFav;

 //ImageView/v.findViewById/R.id.bookmark_star//.setImageResource/itemListsItems.get/position/.isFav ? R.mipmap.active_star : R.mipmap.inactive_star/;



 if/itemListsItems.get/position/.isFav/{

 String data = Integer.toString/itemListsItems.get/position/.id/;

 Toast.makeText/v.getContext//,"fav hai "+data,Toast.LENGTH_SHORT/.show//;

 pref.addPref/data/;

 } else {

 String data = Integer.toString/itemListsItems.get/position/.id/;

 Toast.makeText/v.getContext//,"not fav"+ data,Toast.LENGTH_SHORT/.show//;

 pref.removePref/data/;

 }

 //notifyDataSetChanged//;

 }

 }/;



 //ImageView/convertView.findViewById/R.id.bookmark_star//.setImageResource/itemListsItems.get/position/.isFav ? R.mipmap.active_star : R.mipmap.inactive_star/;



 /*

 if/itemListsItems.get/position/.isFav/{

 String data = Integer.toString/itemListsItems.get/position/.id/;

 Toast.makeText/convertView.getContext//,"fav hai "+data,Toast.LENGTH_SHORT/.show//;

 pref.addPref/data/;

 } else {

 String data = Integer.toString/itemListsItems.get/position/.id/;

 //Toast.makeText/convertView.getContext//,"not fav"+ data,Toast.LENGTH_SHORT/.show//;

 pref.removePref/data/;

 }

 */

 return convertView;

}



private static class ViewHolder {

 public TextView Title, Desc,Cat,id;

 ImageView book;

 NetworkImageView img;

}

还要记住，使列表布局成为

android:focussable="true"

以及此按钮参数/文本使用

android:focussable="false"

.
</itemlist></itemlist>

添加属性

android:focusable="false"

在按钮和父演示文稿中，添加属性

android:descendantFocusability="blocksDescendants"

通过以下方式。

<relativelayout android:descendantfocusability="blocksDescendants" android:layout_height="wrap_content" android:layout_width="match_parent">

<imagebutton android:focusable="false" android:id="@+id/sell_button" android:layout_height="wrap_content" android:layout_width="wrap_content" android:src="@drawable/ic_sell"></imagebutton>

</relativelayout>

我绝对不知道为什么，但有时，当您安装适配器时，可以清理侦听器。然后你要打电话

setOnClickListener

后

setAdapter

或者

setListAdapter

去掉

使父冻结属性相等 false, 像这样

android:clickable="false"

<linearlayout android:clickable="false" android:layout_height="wrap_content" android:layout_width="match_parent" android:orientation="vertical" xmlns:android="[url=http://schemas.android.com/apk/res/android">]http://schemas.android.com/apk ... gt%3B[/url]

再次面对问题，然后添加所有子公司的可点击谎言。
