由於某種原因，即使我擁有正確的偵聽器代碼，在列表視圖中點擊某行也不起作用。列表模板中只有文本視圖。我知道當列表視圖模板中有一個按鈕時，有關於分配監聽器的討論。見here。在Listview中點擊行甚至無法在Android中運行SetOnItemClicklistener
這裏是我的代碼：
ScheduleActivity：
public class ScheduleActivity extends AppCompatActivity {
private String url;
JSONObject data = null;
Toolbar toolbar;
Intent intent;
String userId;
int eventId;
ListView scheduleListView;
ScheduleAdapter scheduleAdapter;
ArrayList<Schedule> scheduleList = new ArrayList<>();
DBManager dbManager = new DBManager(ScheduleActivity.this);
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.schedule_layout);
Log.d("Test", ">>>ScheduleActivity<<<");
Bundle extras = getIntent().getExtras();
userId = extras.getString("userId");
eventId = extras.getInt("eventId");
toolbar = (Toolbar) findViewById(R.id.schedule_toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setTitle("Schedules");
scheduleList = dbManager.getSchedules(eventId);
scheduleAdapter = new ScheduleAdapter(ScheduleActivity.this, scheduleList);
scheduleListView = (ListView) findViewById(R.id.scheduleListView);
scheduleListView.setAdapter(scheduleAdapter);
scheduleListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.w("Test", scheduleList.get(position).toString());
intent = new Intent(ScheduleActivity.this, UpdateScheduleActivity.class);
intent.putExtra("userId", userId);
intent.putExtra("eventId", eventId);
startActivity(intent);
}
});
scheduleListView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
@Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
Log.w("Test", "Long click works");
return true;
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.schedule_menu, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.new_schedule) {
intent = new Intent(ScheduleActivity.this, CreateScheduleActivity.class);
intent.putExtra("eventId", eventId);
startActivity(intent);
}else if(id == R.id.rankings){
Log.d("Test", "Rankings Activity clicked!");
}
return super.onOptionsItemSelected(item);
}
ScheduleAdapter：
public class ScheduleAdapter extends ArrayAdapter<Schedule>{
public ScheduleAdapter(Context context, List<Schedule> schedule) {
super(context, R.layout.schedule_list_row, schedule);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater eventInflater = LayoutInflater.from(getContext());
if (convertView == null) {
convertView = eventInflater.inflate(R.layout.schedule_list_row, parent, false);
}
Schedule singleSchedule = getItem(position);
//TODO implement ViewHolder pattern
TextView club1Code = (TextView) convertView.findViewById(R.id.club1TextView);
TextView club2Code= (TextView) convertView.findViewById(R.id.club2TextView);
TextView club1Score = (TextView) convertView.findViewById(R.id.club1ScoreTextView);
TextView club2Score = (TextView) convertView.findViewById(R.id.club2ScoreTextView);
TextView club1SpiritScore = (TextView) convertView.findViewById(R.id.club1SpiritScoreTextView);
TextView club2SpiritScore = (TextView) convertView.findViewById(R.id.club2SpiritScoreTextView);
TextView time = (TextView) convertView.findViewById(R.id.timeTextView);
TextView day = (TextView) convertView.findViewById(R.id.dayTextView);
club1Code.setText(singleSchedule.getClub1Id());
club2Code.setText(singleSchedule.getClub2Id());
day.setText("Day " + singleSchedule.getDay());
time.setText(singleSchedule.getStartTime() + " - " + singleSchedule.getEndTime());
club1Score.setText(Integer.toString(singleSchedule.getClub1Score()));
club2Score.setText(Integer.toString(singleSchedule.getClub2Score()));
club1SpiritScore.setText(Integer.toString(singleSchedule.getClub1SpiritScore()));
club2SpiritScore.setText(Integer.toString(singleSchedule.getClub2SpiritScore()));
return convertView;
}
}
