java - 创建 onItemClickListener 时出现问题

Question

我正在尝试将 onItemClickListener 添加到我的 ListView

streamListView.setAdapter(this.streamAdapter);
            this.streamListView.setOnItemClickListener(new OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> a, View v, int position, long id) {
                    Intent intent = new Intent(this, MessageDetailActivity.class);
                    startActivity(intent);
                }
            });

但我收到错误:

The constructor Intent(new AdapterView.OnItemClickListener(){}, Class<MessageDetailActivity>) is undefined

Answer 1

annonymos 类中的

this 类型为 AdapterView.OnItemClickListener，使用 YOURACTIVITYNAME.this 来引用 Activity 。

public class MyActivity extends Activity {
....
streamListView.setAdapter(this.streamAdapter);
     this.streamListView.setOnItemClickListener(new OnItemClickListener() {
         @Override
            public void onItemClick(AdapterView<?> a, View v, int position, long id) {
>>>>>       Intent intent = new Intent(MyActivity.this, MessageDetailActivity.class);
                startActivity(intent);
            }
     });
...
}
