将 OnItemClickListener 设置为 ListView

Question

它的我的代码：

 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);

问题是我尝试将 OnItemClickListener 设置为 lv。如何初始化 lv？ 我有 Activity extends ListActivity.I 找不到 lv id，因为 ListView 有 id=android:id/list。 我有适配器，使用 setListAdapter(adapter) 和 all.How 为 lv 设置监听器？

首先在 onCreate() 中初始化你的 lv，然后像下面那样做，

  ListView lv;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        new ProgressTask(MainActivity.this).execute();
        //Supposing your listview is from android package
        lv = (ListView)findViewById(android.R.id.list); 
        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);

我建议使用 RecyclerView，您可以在列表中的每个项目上设置 OnclickListener。 列表视图不再流行。 设置值时使用 RecyclerView 的示例：

 @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
        AnyViewHolder view = (AnyViewHolder ) holder;
            view.layout.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    //Do something
                }

            });
        }
    }
