我需要帮助来实现在listview项目上简单的点击以打开一个新活动。我在这里看到很多类似的问题,但没有人帮助我。
public class CustomListView extends ListActivity {
private EfficientAdapter adap;
...
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.main);
adap = new EfficientAdapter(this);
setListAdapter(adap);
}
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
super.onListItemClick(l, v, position, id);
startActivity(new Intent(CustomListView.this, next.class));
}
public static class EfficientAdapter extends BaseAdapter implements Filterable {
private LayoutInflater mInflater;
private Bitmap mIcon1;
private Context context;
public EfficientAdapter(Context context) {
// Cache the LayoutInflate to avoid asking for a new one each time.
mInflater = LayoutInflater.from(context);
this.context = context;
}
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.adaptor_content, null);
convertView.setOnClickListener(new OnClickListener() {
private int pos = position;
@Override
public void onClick(View v) {
}
});
convertView.setTag(holder);
}else{
// Get the ViewHolder back to get fast access to the TextView
// and the ImageView.
holder = (ViewHolder) convertView.getTag();
}
return convertView;
}
...
}
}
我也尝试在CustomListView类的onCreate方法中添加下面的代码,但它也不起作用。
ListView lv = getListView();
// listening to single list item on click
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
startActivity(new Intent(CustomListView.this, next.class));
}
});
Intent
构造函数中传递的one.this
中的one
是什么?尝试使用CustomListView.this
