Question

我的代码：

 ListView lv=getListView();
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        new ProgressTask(MainActivity.this).execute();
        ImageView image = (ImageView)findViewById(R.id.image);
    !!!  lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

                intent = new Intent(MainActivity.this,DetailInfo.class);
                intent.putExtra("title",jsonlist.get(position).get("title"));
                intent.putExtra("description",jsonlist.get(position).get("description"));
                intent.putExtra("description",jsonlist.get(position).get("description"));
                intent.putExtra("url",jsonlist.get(position).get("image"));
startActivity(intent);

问题是我试着将OnItemClickListener设置为lv.How我可以初始化lv吗？我有Activity扩展ListActivity.I无法找到id的id，因为ListView有id = android：id / list。我有适配器，使用setListAdapter（适配器）和all.How我可以为lv设置监听器吗？

首先在onCreate（）中初始化你的lv，并在下面执行，

def issorted(numlist):
    previous = numlist[0]
    for value in numlist:
        if value < previous:
            # the current value is smaller than the previous,
            # so the list is not (forward) sorted. Exit with False
            return False
        previous = value
    # all values were equal or larger than their predecessors, so 
    # the list is sorted, exit with True
    return True

将OnItemClickListener设置为ListView
