我正在處理報警我設置了整個報警系統（模型，數據庫，服務，接收器等），但除此之外。製作ListView時出現問題，每個項目顯示一個模型的ArrayList
我根據基於用戶輸入的重複日期（星期日 - 星期六），將每個鬧鐘分組在名爲「matchingAlarms」的數組列表中。 我與matchingAlarms ArrayList中，我試圖讓一個ListView其中在ListView中的每一項顯示爲ArrayList中的每個索引的報警名稱和報警時間（我希望他們得到這個部分了，這裏沒有問題
現在用定時器在ListView中更改）。
實施例：
我有1個報警：8 AM - 11 PM，重複天數：太陽週四 AND 1報警上午09點 - 下午12點，重複天數：星期五至六
那些報警中的每一個都在matchingAlarms ArrayList中的索引， 所以matchingAlarms大小是2
我想我提到了一切，現在是代碼。
AlarmListAdapter：
public class AlarmListAdapter extends BaseAdapter {
public static Context mContext;
private List<AlarmModel> mAlarms;
private ArrayList<ArrayList<AlarmModel>> mMatchingAlarms = new ArrayList<ArrayList<AlarmModel>>();
private ArrayList<AlarmModel> grouped = new ArrayList<AlarmModel>();
private Animation anim;
AlarmModel model;
TextView txtTime,txtName,sun,mon,tue,wed,thur,fri,sat;
ToggleButton btnToggle;
int matchingAlarmsIndex = 0;
int groupIndex = 0;
int itemIndex;
public AlarmListAdapter(Context context, List<AlarmModel> alarms, ArrayList<ArrayList<AlarmModel>> matchingAlarms) {
mContext = context;
mAlarms = alarms;
mMatchingAlarms = matchingAlarms;
anim = AnimationUtils.loadAnimation(mContext, R.anim.right_left);
}
public AlarmListAdapter(Context context) {
mContext = context;
}
public void setAlarms(List<AlarmModel> alarms) {
mAlarms = alarms;
}
@Override
public int getCount() {
if (mMatchingAlarms != null) {
return mMatchingAlarms.size();
}
return 0;
}
@Override
public ArrayList<AlarmModel> getItem(int position) {
if (mMatchingAlarms != null) {
return mMatchingAlarms.get(position);
}
return null;
}
@Override
public long getItemId(int position) {
if (mAlarms != null) {
return mAlarms.get(position).id;
}
return 0;
}
@Override
public View getView(int position, View view, ViewGroup parent) {
if (view == null) {
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.alarm_list_item, parent, false);
}
txtName = (TextView) view.findViewById(R.id.alarm_item_name);
txtTime = (TextView) view.findViewById(R.id.alarm_item_time);
sun = (TextView) view.findViewById(R.id.alarm_item_sunday);
mon = (TextView) view.findViewById(R.id.alarm_item_monday);
tue = (TextView) view.findViewById(R.id.alarm_item_tuesday);
wed = (TextView) view.findViewById(R.id.alarm_item_wednesday);
thur = (TextView) view.findViewById(R.id.alarm_item_thursday);
fri = (TextView) view.findViewById(R.id.alarm_item_friday);
sat = (TextView) view.findViewById(R.id.alarm_item_saturday);
btnToggle = (ToggleButton) view.findViewById(R.id.alarm_item_toggle);
grouped = getItem(position);
Timer timer = new Timer();
timer.scheduleAtFixedRate(new TimerTask() {
public void run() {
((AlarmListActivity) mContext).runOnUiThread(new Runnable() {
@Override
public void run() {
if ((groupIndex + 1) <= grouped.size()) {
model = grouped.get(groupIndex);
updateTimeAndDates(model);
groupIndex++;
}
if ((groupIndex + 1) > grouped.size()) {
groupIndex = 0;
}
Log.i("", String.valueOf(groupIndex));
}
});
}
}, 0, 2500);
return view;
}
private void updateTextColor(TextView view, boolean isOn) {
if (isOn) {
view.setTextColor(Colors.IndianRed);
} else {
view.setTextColor(Color.LTGRAY);
}
}
private void updateTimeAndDates(AlarmModel model) {
txtName.setText(model.name);
txtName.startAnimation(anim);
txtTime.setText(DietDoctor.to12Hours(model.timeHour, model.timeMinute));
txtTime.startAnimation(anim);
updateTextColor(sun, model.getRepeatingDay(AlarmModel.SUNDAY));
updateTextColor(mon, model.getRepeatingDay(AlarmModel.MONDAY));
updateTextColor(tue, model.getRepeatingDay(AlarmModel.TUESDAY));
updateTextColor(wed, model.getRepeatingDay(AlarmModel.WEDNESDAY));
updateTextColor(thur, model.getRepeatingDay(AlarmModel.THURSDAY));
updateTextColor(fri, model.getRepeatingDay(AlarmModel.FRDIAY));
updateTextColor(sat, model.getRepeatingDay(AlarmModel.SATURDAY));
btnToggle.setChecked(model.isEnabled);
}
}
AlarmListActivity：
public class AlarmListActivity extends ListActivity {
private AlarmListAdapter mAdapter;
private AlarmDBHelper dbHelper = new AlarmDBHelper(this);
private Context mContext;
private boolean fromSettings;
private ArrayList<ArrayList<AlarmModel>> matchingAlarms = new ArrayList<ArrayList<AlarmModel>>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(getIntent().hasExtra("FromSettings"))
fromSettings = getIntent().getExtras().getBoolean("FromSettings");
mContext = this;
requestWindowFeature(Window.FEATURE_ACTION_BAR);
setContentView(R.layout.activity_alarmlist);
setGroups();
mAdapter = new AlarmListAdapter(this, dbHelper.getAlarms(), matchingAlarms);
setListAdapter(mAdapter);
}
...
public void setGroups() {
ArrayList<AlarmModel> group = new ArrayList<AlarmModel>();
List<AlarmModel> mAlarms = dbHelper.getAlarms();
for (int i = 0; i < mAlarms.size(); i++) {
if ((i + 1) != mAlarms.size()) {
boolean result = Arrays.equals(mAlarms.get(i).getRepeatingDays(), mAlarms.get(i + 1).getRepeatingDays());
Log.i("Result", Boolean.toString(result));
if (result) {
if (i == 0)group.add(mAlarms.get(i));
group.add(mAlarms.get(i+1));
}
if (!result) {
if (i == 0)group.add(mAlarms.get(i));
matchingAlarms.add(group);
group = new ArrayList<AlarmModel>();
group.add(mAlarms.get(i+1));
}
}
if ((i + 1) == mAlarms.size()) {
boolean result1 = Arrays.equals(mAlarms.get(i).getRepeatingDays(), mAlarms.get(i - 1).getRepeatingDays());
Log.i("Result_1", Boolean.toString(result1));
if (result1) {
group.add(mAlarms.get(i));
matchingAlarms.add(group);
}
if (!result1) {
matchingAlarms.add(group);
group = new ArrayList<AlarmModel>();
group.add(mAlarms.get(i));
}
}
}
Log.i("Matching Alarms", String.valueOf(matchingAlarms.size()));
Log.i("Group", String.valueOf(matchingAlarms.get(0).size()));
Log.i("UnGrouped", String.valueOf(mAlarms.size()));
}
我認爲真正的問題出在getView方法及其中的計時器。 正如你從下面的圖片可以看到，我只有週五週六去。第一個項目應該有重複的天報警：太陽週四
