カスタム レイアウトを使用してアプリにリストビューを実装したので、カスタム アダプターが必要でした。このリストビューを埋めようとすると、アプリがクラッシュし続けます。
これは私の活動です：
public class PersonalResultsActivity extends Activity {
private PersonalResultsAdapter resultListAdapter;
private ListView resultListView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.personal_results);
resultListView = (ListView)findViewById(R.id.pers_res_list);
resultListAdapter = new PersonalResultsAdapter(this);
resultListView.setAdapter(resultListAdapter);
}
}
これは私のアダプタークラスです:
public class PersonalResultsAdapter extends ArrayAdapter<Result> {
private Context context;
private List<Result> results;
private LayoutInflater mInflater;
private boolean mNotifyOnChange = true;
private String username;
private Student student;
private TestData test;
public PersonalResultsAdapter(Context context) {
super(context, R.layout.result_item_row);
test = LoginActivity.testData;
username = LoginActivity.loadPreferences(context);
student = test.getStudent(username);
results = student.getResults();
this.context = context;
this.mInflater = LayoutInflater.from(context);
}
@Override
public int getCount() {
return results .size();
}
@Override
public Result getItem(int position) {
return results .get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public int getPosition(Result item) {
return results .indexOf(item);
}
@Override
public int getViewTypeCount() {
return 1; //Number of types + 1 !!!!!!!!
}
@Override
public int getItemViewType(int position) {
return 1;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
final ViewHolder holder;
int type = getItemViewType(position);
if (convertView == null) {
holder = new ViewHolder();
switch (type) {
case 1:
convertView = mInflater.inflate(R.layout.result_item_row,parent, false);
holder.date = (TextView) convertView.findViewById(R.id.pers_res_date);
holder.meeting = (TextView) convertView.findViewById(R.id.pers_res_meet);
holder.points = (TextView) convertView.findViewById(R.id.pers_res_points);
break;
}
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
Time temp = results.get(position).getDate();
String strDate = temp.year + "/" + temp.month + "/" + temp.monthDay;
holder.date.setText(strDate);
holder.meeting.setText(results.get(position).getMeeting().getName());
holder.points.setText(results.get(position).getScore());
holder.pos = position;
return convertView;
}
@Override
public void notifyDataSetChanged() {
super.notifyDataSetChanged();
mNotifyOnChange = true;
}
public void setNotifyOnChange(boolean notifyOnChange) {
mNotifyOnChange = notifyOnChange;
}
static class ViewHolder {
TextView date;
TextView meeting;
TextView points;
int pos; //to store the position of the item within the list
}
}
レイアウト：
</TableRow>
</TableLayout>
<ListView
android:id="@+id/pers_res_list"
android:background="@drawable/border"
android:layout_height="280dp"
android:layout_width="250dp"
android:layout_gravity="center"/>
</LinearLayout>
リストビュー項目のカスタム レイアウト:
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="wrap_content"
