android中的listview无法获得价值

Question

我在ListView中有价值，但我无法选择任何值

list.setOnItemClickListener(new OnItemClickListener() 

             {
                 public void onItemClick(AdapterView<?> parent, View view, int position, long i) 
                 {
                         try{                            
                             String phone = adapter.tvPhone.getText().toString();
                         }
                         catch(Exception e) {
                         System.out.println("error 1:: " + e );
                             Log.i(" error1 :: "+e,null);
                     }

                 }

list.setOnItemClickListener(new OnItemClickListener() 

             {
                 public void onItemClick(AdapterView<?> parent, View view, int position, long i) 
                 {
                         try{                            
                             String phone =  list.getItemAtPosition(position).toString();
                             Toast.makeText(getBaseContext(), phone, 1000).show();
                         }
                         catch(Exception e) {
                         System.out.println("error 1:: " + e );
                             Log.i(" error1 :: "+e,null);
                     }

                 }
             });"

如果你只有文本视图作为列表项，你可以这样做：

    public void onItemClick(AdapterView<?> parent, View view, int position, long i) 
             {
                     try{                            
                         String phone = ((TextView)view).getText().toString();
                     }
                     catch(Exception e) {
                     System.out.println("error 1:: " + e );
                         Log.i(" error1 :: "+e,null);
                 }

             }
