Question

如何在Android Studio中点击listview中的项目打开新活动？或者更确切地说 - 我只是一个问题。问题在代码中描述。对不起我的英语不好！！！这是代码`

public class MainActivity extends Activity {

ListView listView;
ArrayAdapter<String> adapter;
String[] android_versions= { "Jelly Bean", "Kitkat", "Donut",
        "Eclair", "Froyo", "Honeycomb", "Ice Cream"
         };

@Override
protected void onCreate(Bundle savedInstanceState)
{
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
   setContentView(R.layout.activity_main);
    listView = (ListView)findViewById(R.id.list_view);
    adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,android_versions);
    listView.setAdapter(adapter);
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

        //Here´s the problem! The super.OnItemClick 
        //doesn´t work.//


            super.OnItemClick(parent, view, position, id);

         //Here´s the problem! The super. doesn´t work.//

            if (position == 0) {
                Intent intent = new Intent(this, JellyBean.class);
                startActivity(intent);
            }
            else if (position == 1) {
                Intent intent = new Intent(this, Kitkat.class);
                startActivity(intent);
            }
            else if (position == 2) {
                Intent intent = new Intent(this, Donut.class);
                startActivity(intent);
            }
        }
    }
}
}

Answer 1

删除 super.OnItemClick（父级，视图，位置，ID）;

Intent myIntent = new Intent(view.getContext(), JellyBean.class);
startActivity(intent);

Answer 2

由于ItemClickListener是界面，因此没有super实施，因此您可以删除super.OnItemClick
