Question

我想设计ListView中的每个列表项都是可以点击的，并且可以选择单击哪个列表项。但它不能。我尝试了两个方法：setOnItemClickListener（）和setOnItemSelectedListener（）在我的代码上。我已经搜索过有关该文章的几个参考文献，但它仍然无法工作（可点击）我想发布下面的代码：代码可以显示列表项，我可以看到 Log.d（“mListView01.getCount（）=”，“”+ vc）行的Log.d内容; 在LogCat上。但是，如果我点击列表项目，则没有任何回复。如果你不介意，你能帮我指出我错在哪里，谢谢！

使用Activity Widget创建listView的代码：

......
setContentView(R.layout.main_open);
    TextView itemText = (TextView) findViewById(R.id.itemText);
    TextView codeText = (TextView) findViewById(R.id.codeText);
    itemText.setText(selectedItem);
    codeText.setText(selectedCode);
    ListView mListView01 = (ListView)findViewById(R.id.main_open_listview1);
    String[] keys = new String[] {"title","title_image", "content",
            "title1","title1_image","content1","title2","title2_image","content2"};
    int[] resValues =  new int[] { R.id.title, R.id.title_image, R.id.content,
            R.id.title1, R.id.title1_image, R.id.content1,R.id.title2, R.id.title2_image, R.id.content2};
    openDocAdapter opendoc = new openDocAdapter(this,localdcoumentlist, R.layout.main_open_content, keys, resValues );
    mListView01.setSelected(true);
    mListView01.setClickable(true);
    mListView01.setAdapter(opendoc);       

    int vc = mListView01.getCount();
    Log.d(" mListView01.getCount()="," "+vc);

    mListView01.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView<?> arg0, View arg1,
                    int arg2, long arg3) {
                // TODO Auto-generated method stub
                Log.d("Selected From setOnItemSelectedListener, arg2=", " "+ arg2);
            }

            @Override
            public void onNothingSelected(AdapterView<?> arg0) {
                // TODO Auto-generated method stub

            }
        });


    mListView01.setOnItemClickListener(new AdapterView.OnItemClickListener()
    {
            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                    long arg3) {
                // TODO Auto-generated method stub
                selectedViewPos = arg2;
                Log.d("TitlesSelectionDialog(),selectedViewPos= "," "+ selectedViewPos);
                Toast.makeText(getApplicationContext(), "selectedViewPos= "+ selectedViewPos, Toast.LENGTH_LONG).show();

            }
        });
......

openDocAdapter的代码：

   private class openDocAdapter extends SimpleAdapter
    {
      private Context _con;
      private List _List;
      private int _listviewId;
      private String[] _keys;
      private int[] _resValues;


      public openDocAdapter(Context context, ArrayList<HashMap<String,Object>> List , int listviewId, String[] keys, int[] resValues ) 
      {
        super(context, List, listviewId, keys, resValues);
        _con =context;
        _List = List;
        _listviewId = listviewId;
        _keys = keys;
        _resValues = resValues;
      }

      @Override
      public View getView(int position, View convertView, ViewGroup parent)
      {
          View v = convertView;
          if (v == null) {
              LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
              v = vi.inflate(R.layout.main_open_content, null);
          }

          TextView title = (TextView) v.findViewById(R.id.title);
          (...Similiar codes define  textView, imageViewsd.)                            

          return v;
      }


      @Override
      public int getCount()
      {
        // TODO Auto-generated method stub
        return super.getCount();
      }
      @Override
      public Object getItem(int position)
      {
        // TODO Auto-generated method stub
        return super.getItem(position);
      }
      @Override
      public long getItemId(int position)
      {
        // TODO Auto-generated method stub
        return super.getItemId(position);
      }
    }

Edit1：我发现article here关于布局上的焦点设置会导致可点击的工作或无法正常工作。所以，我在布局的xml文件中删除（我不在这里编码）的行。然后在使用橙色焦点更改滚动列表列表时处理setOnItemSelectedListener（）方法。但它仍然不符合我的期望。

Provlem解决了！经过几次hous谷歌搜索/搜索和try_eror。如果你感兴趣，我想分享它。

问题的主要原因是：我使用 ScrollView 作为row.xml的基本布局（包含每个listview行的内容）。然后，我使用了 LinearLayout（Vertial）而不是它。 setOnItemClickedListener（）方法现在正常工作。我对此没有任何想法会导致ListView无法点击。如果有人知道，请告诉我们，

Android ListView项目不可点击
