创建 onItemClickListener 时的问题

Question

我想在ListView中添加一个onItemClickListenerstreamListView.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);                 }             });但是得到错误提醒：The constructor Intent(new AdapterView.OnItemClickListener(){}, Class<MessageDetailActivity>) is undefined如何解决这个问题呢？

Answer 1

在 annonymos 类里 this 是 AdapterView.OnItemClickListener 类型的，用 YOURACTIVITYNAME.this 来指代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);
            }
     });
...
}

Answer 2

Intent intent = new Intent(this, MessageDetailActivity.class);
试下这两种方法
1：将this改为myMainActivity.this//myMainActivity为你本主activity的名字
2：将这句Intent提到onClick上面去
