Question

所以我有一个simpleadapter使用listadapter，行将显示，数据在那里，但listview不可点击！我错过了任何代码或东西吗？请帮忙！我需要listview才能使用intent转到另一个页面。任何帮助表示赞赏！

    ListAdapter adapter = new SimpleAdapter(
                        AllFTemployeesActivity.this, employeesList,
                        R.layout.list_item_ft, new String[] { TAG_PID,
                                TAG_NAME,TAG_DESCRIPTION},
                        new int[] { R.id.pid, R.id.name, R.id.description});

                // updating listview
                setListAdapter(adapter);

                ListView lv = getListView();
                lv.setTextFilterEnabled(true);


                //inflater = (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

               //  View header = inflater.inflate(R.layout.planets_heade_view, null);

               // lv.addHeaderView(header);

                 // on seleting single fulltime employee
                 // launching Edit single fulltime employee Screen
                lv.setOnItemClickListener(new OnItemClickListener() {

                    @Override
                     public void onItemClick(AdapterView<?> parent, View view,
                             int position, long id) {
                         // getting values from selected ListItem
                       //  String pid = ((TextView) view.findViewById(R.id.pid)).getText()
                        //         .toString();


                         // Starting new intent
                         Intent i = new Intent(getApplicationContext(),
                                 EmployeePayslip.class);
                         // sending pid to next activity
                       //  in.putExtra(TAG_PID, pid);

                         // starting new activity and expecting some response back
                         startActivity(i);

                     }
                 });

这是listview的以下xml文件;对不起代码的混乱！

Answer 1

    adapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,a);
    sp.setAdapter(adapter);
    sp.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {
            // TODO Auto-generated method stub


                Toast.makeText(getBaseContext(), "Redirecting..."+a[arg2], Toast.LENGTH_LONG).show();
                Intent i = new Intent(getBaseContext(),EmployeePayslip.class);
                startActivity(i);


        }

Answer 2

使用Listview项目单击侦听器

getListView().setOnItemClickListener(new OnItemClickListener() {    
    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
        // your code is here on item click
    }
});

Answer 3

而不是toast msg添加意图代码....一切都会好的

ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView<?> parent, View
view,int position, long id)
{
// When clicked, show a toast with the TextView text
Toast.makeText(getApplicationContext(), ((TextView)
view).getText(),Toast.LENGTH_SHORT).show();
}
});

如何使listview可点击？我尝试了很多方法，但我仍然不明白
