我有一个每行都有文本和按钮的列表视图，列表视图 setOnItemClickListener() 不起作用.是否可以以不同的方式处理项目单击和按钮单击事件(项目单击应调用 ActivityA，按钮单击应调用 ActivityB).有没有人有解决办法

I have a list view with text and button in each row, list view setOnItemClickListener() is not working. is it possible to handle item click and button click events differently(item click should call ActivityA and button click should call ActivityB). Does anyone have a solution

    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>> 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;
        }
    }
}`

推荐答案

尝试像这样设置你的按钮(或任何其他你想要处理列表项内点击的视图):

Try setting your buttons (or any other views you want to handle click inside a list item) like this:

android:focusable="false"
android:focusableInTouchMode="false"
