我只是Android(Java)的新手,我想从我的Custom ListView中获取所选用户的值,以下是我试图检索数据的示例代码
ContactsListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
// String str= ContactsListView.getSelectedItem();
//String selectedFromList = (ContactsListView.getItemAtPosition(position).toString());
String val = parent.getAdapter().getItem(position).toString();
Log.i("Item", "Selected: " + val);
}
});
但这就是越来越
02-04 18:16:31.773 10255-10255 / com.app.com.sms I / Item:已选择:
com.app.com.smsapp.ThreeStrings@42829718 02-04 18:16:33.323
10255-10255 / com.app.com.sms I / Item:已选择:
com.app.com.smsapp.ThreeStrings@428297c0 02-04 18:16:34.463
10255-10255 / com.app.com.sms I / Item:已选择:
com.app.com.smsapp.ThreeStrings@42829718
这是我的适配器
public class ThreeHorizontalTextViewsAdapter extends
ArrayAdapter<ThreeStrings> {
private int layoutResource;
public ThreeHorizontalTextViewsAdapter(Context context, int layoutResource, List<ThreeStrings> threeStringsList) {
super(context, layoutResource, threeStringsList);
this.layoutResource = layoutResource;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
LayoutInflater layoutInflater = LayoutInflater.from(getContext());
view = layoutInflater.inflate(layoutResource, null);
}
ThreeStrings threeStrings = getItem(position);
if (threeStrings != null) {
TextView leftTextView = (TextView) view.findViewById(R.id.leftTextView);
TextView rightTextView = (TextView) view.findViewById(R.id.rightTextView);
TextView centreTextView = (TextView) view.findViewById(R.id.centreTextView);
TextView text_from = (TextView) view.findViewById(R.id.text_from);
if (leftTextView != null) {
leftTextView.setText(threeStrings.getLeft().toUpperCase());
}
if (rightTextView != null) {
rightTextView.setText(threeStrings.getRight());
}
if (centreTextView != null) {
centreTextView.setText(threeStrings.getCentre());
}
if (text_from != null) {
text_from.setText(threeStrings.getBottom());
}
}
return view;
} }
public class ThreeStrings {
private String left;
private String right;
private String centre;
private String bottom;
public ThreeStrings(String left, String right, String centre, String bottom) {
this.left = left;
this.right = right;
this.centre = centre;
this.bottom = bottom;
}
public String getLeft() {
return left;
}
public String getCentre() {
return centre;
}
public String getRight() {
return right;
}
public String getBottom() {return bottom;}
}
在listView中,将定位在中心作为选定值。如何获得所选商品的价值/中心?
最佳答案
您可以在下面执行以下操作:
ContactsListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
ThreeStrings threeStrings = (ThreeStrings)ContactsListView.getItemAtPosition(position);
Log.i("Item", "Selected: " + threeStrings.getCentre());
}
});
