我有一个可扩展的列表视图，当单击时，切换到带有3个选项卡的tablayout，每个选项卡包含一个列表视图。根据在可扩展列表视图中单击的项目，3个选项卡将填充不同的数据。
我已经把它全部设置好所以我认为它可能（可能）有效..但我在列表视图中添加行时遇到了麻烦。当我添加此行时，我不知道要为复选框添加什么（我认为false会将其设置为未选中）：
mCustomListViewAdapter.addAdapterItem(new CustomObject("Squats", "60%", "6", "150", false);
我也开始怀疑这是最好的方法。我并不担心它是不是最好的方法，因为它只是我和一些朋友的应用程序，但我担心这样做是迟滞/崩溃这样做
这是我的可扩展列表视图代码，假设将其发送到下一个活动并使用自定义适配器添加所需的对象。
public class MyWorkout extends BaseActivity {
ExpandableListView expandableListView;
HashMap<String, List<String>> Workouts_details;
List<String> Workout_list;
WorkoutsAdapter mAdapter;
CustomListViewAdapter mCustomListViewAdapter;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_workout);
mToolBar = activateToolbar();
setUpNavigationDrawer();
expandableListView = (ExpandableListView) findViewById(R.id.listViewWorkouts);
Workouts_details = DataProvider.getInfo();
Workout_list = new ArrayList<>(Workouts_details.keySet());
mAdapter = new WorkoutsAdapter(this, Workouts_details, Workout_list);
final ListView listViewFri = (ListView) findViewById(R.id.listViewFri);
final ListView listViewMon = (ListView) findViewById(R.id.listViewMon);
final ListView listViewWed = (ListView) findViewById(R.id.listViewWed);
expandableListView.setAdapter(mAdapter);
expandableListView.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
@Override
public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {
if (groupPosition == 0) {
if (childPosition == 0) {
listViewFri.setAdapter(mCustomListViewAdapter);
mCustomListViewAdapter.addAdapterItem(new CustomObject("Squats", "60%", "6", "150", false);
listViewMon.setAdapter(mCustomListViewAdapter);
// TODO: ADD ALL ITEMS FOR TAB
listViewWed.setAdapter(mCustomListViewAdapter);
// TODO: ADD ALL ITEMS FOR TAB
Intent intent = new Intent(getApplicationContext(), WorkoutDaysActivity.class);
startActivity(intent);
}
if (childPosition == 1) {
Intent intent = new Intent(getApplicationContext(), WorkoutDaysActivity.class);
startActivity(intent);
}
if (childPosition == 2) {
Intent intent = new Intent(getApplicationContext(), WorkoutDaysActivity.class);
startActivity(intent);
}
if (childPosition == 3) {
Intent intent = new Intent(getApplicationContext(), WorkoutDaysActivity.class);
startActivity(intent);
} else return false; }
if (groupPosition == 1) {
if (childPosition == 0) {
Intent intent = new Intent(getApplicationContext(), WorkoutDaysActivity.class);
startActivity(intent);
}
if (childPosition == 1) {
Intent intent = new Intent(getApplicationContext(), WorkoutDaysActivity.class);
startActivity(intent);
}
if (childPosition == 2) {
Intent intent = new Intent(getApplicationContext(), WorkoutDaysActivity.class);
startActivity(intent);
}
if (childPosition == 3) {
Intent intent = new Intent(getApplicationContext(), WorkoutDaysActivity.class);
startActivity(intent);
} else return false; }
}
return false;
}
这是我的惯例：
public class CustomListViewAdapter extends BaseAdapter {
private LayoutInflater inflater;
private ArrayList<CustomObject> objects;
private class ViewHolder {
TextView txtExercise;
TextView txtPercent;
TextView txtReps;
TextView txtWeight;
CheckBox check1;
}
public void addAdapterItem(CustomObject item) {
objects.add(item);
}
public CustomListViewAdapter(Context context, ArrayList<CustomObject> objects) {
inflater = LayoutInflater.from(context);
this.objects = objects;
}
public int getCount() {
return objects.size();
}
public CustomObject getItem(int position) {
return objects.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
if(convertView == null) {
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.workout_item, null);
holder.txtExercise = (TextView) convertView.findViewById(R.id.txtExercise);
holder.txtPercent = (TextView) convertView.findViewById(R.id.txtPercentage);
holder.txtReps = (TextView) convertView.findViewById(R.id.txtReps);
holder.txtWeight = (TextView) convertView.findViewById(R.id.txtWeight);
holder.check1 = (CheckBox) convertView.findViewById(R.id.check1);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.txtExercise.setText(objects.get(position).getExercise());
holder.txtPercent.setText(objects.get(position).getPercent());
holder.txtReps.setText(objects.get(position).getReps());
holder.txtWeight.setText(objects.get(position).getWeight());
holder.check1.setChecked(false);
return convertView;
}
}
最后是我的customobject类：
public class CustomObject {
private String exercise;
private String percent;
private String reps;
private String weight;
private CheckBox check1;
public CustomObject(String exercise, String percent, String reps, String weight, CheckBox check1) {
this.exercise = exercise;
this.percent = percent;
this.reps = reps;
this.weight = weight;
this.check1 = check1;
}
public String getExercise() {
return exercise;
}
public String getPercent() {
return percent;
}
public String getReps() {
return reps;
}
public String getWeight() {
return weight;
}
public CheckBox getCheck1() {
return check1;
}
}
感谢您的帮助！请通过添加带复选框的行告诉我如何修复错误。也欢迎其他方式的意见。你认为这会让这个应用程序变得迟钝吗？每个子位置将有3个列表视图，每个列表视图将使适配器添加大约20-25行。根据我的理解，只有点击的子位置将保存信息，而不是其他的（不确定）。每行中的一个值最终将由用户提供的变量替换。
再次感谢！
