Android 动态选中列表中的复选框

我正在处理一个复选框列表视图。到目前为止，我所做的是从本地数据库填充列表，使用

setOnCheckedChangeListener

获取所有选中项的数据库id，并将其存储在本地数据库中的单独表中。这就是我的代码的外观：

@Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        if(convertView == null){
            dbHelper = new DBHelper(con);
            database = dbHelper.getWritableDatabase();
            switch (getItemViewType(position)){
                case DYNAMIC_OBJECTIVE:
                    convertView = layoutInflater.inflate(R.layout.objective_list_view, null);
                    break;
                case STATIC_OBJECTIVE:
                    convertView = layoutInflater.inflate(R.layout.other_objective_list_view, null);
                    break;
            }

            switch (getItemViewType(position)){
                case DYNAMIC_OBJECTIVE:
                    CheckBox checkBox = (CheckBox) convertView.findViewById(R.id.objectiveCheckBox);
                    checkBox.setText(((Objectives)list.get(position)).getObjectiveTitle());

                    checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
                        @Override
                        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                            if (isChecked) {
                                selectedObjectivesMap.put(((Objectives)list.get(position)).getObjectiveID(), "YES");
                            }else{
                                selectedObjectivesMap.put(((Objectives)list.get(position)).getObjectiveID(), "NO");
                            }
                        }
                    });
                    break;
                case STATIC_OBJECTIVE:
                    TextView checkBoxOther = (TextView) convertView.findViewById(R.id.objectiveOtherCheckBox);
                    final TextView objectiveOtherET = (TextView) convertView.findViewById(R.id.objectiveOtherEditText);
                    checkBoxOther.setText((String)list.get(position));
                    //ll = (LinearLayout)convertView.findViewById(R.id.linearLayoutOther);
                    //viewNew = layoutInflater.inflate(R.layout.other_objective_row, null);
                    ImageButton imageButton = (ImageButton) convertView.findViewById(R.id.addOtherObjectiveTextBox);
                    imageButton.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View v) {
                            //Toast.makeText(v.getContext(), "Clicked123", Toast.LENGTH_SHORT).show();
                            final Dialog dialog = new Dialog(v.getContext());
                            dialog.setContentView(R.layout.otherobjectivedialog);

                            final EditText enterObjET = (EditText) dialog.findViewById(R.id.enterObjEditText);
                            Button closeEnterObjBtn = (Button) dialog.findViewById(R.id.closeEnterObjDialog);
                            Button objConfirmBtn = (Button) dialog.findViewById(R.id.enterObjConfirmBtn);

                            closeEnterObjBtn.setOnClickListener(new View.OnClickListener() {
                                @Override
                                public void onClick(View v) {
                                    dialog.dismiss();
                                }
                            });

                            objConfirmBtn.setOnClickListener(new View.OnClickListener() {
                                @Override
                                public void onClick(View v) {
                                    String enteredObj = enterObjET.getText().toString();
                                    if(enteredObj.equals("")){
                                        Toast.makeText(v.getContext(), "Please write a objective", Toast.LENGTH_LONG).show();
                                    }else {
                                        objectiveOtherET.setText(objectiveOtherET.getText().toString()+ " \n" + enteredObj);
                                        otherObjList.add(enteredObj);
                                        dialog.dismiss();
                                    }
                                }
                            });

                            dialog.show();

/*                            LinearLayout linearLayoutNew = new LinearLayout(con);
                            linearLayoutNew.setOrientation(LinearLayout.VERTICAL);
                            et = new EditText(con);
                            LinearLayout.LayoutParams p = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
                            et.setLayoutParams(p);
                            et.setHint("Set some objective");
                            linearLayoutNew.addView(et);
                            ll.addView(linearLayoutNew);*/
                        }
                    });
                    break;
            }

        }
        return convertView;
    }

下面是我填充列表的方式：

ArrayList<Object> objectiveList = new ArrayList<>();
        Cursor crs = database.rawQuery("SELECT * FROM "+ ItemsTable.TABLE_OBJECTIVE +"", null);

        while(crs.moveToNext())
        {
            String title = crs.getString(crs.getColumnIndex("title"));
            int objectiveID = crs.getInt(crs.getColumnIndex("id"));
            objectiveList.add(new Objectives(objectiveID, title));
        }
        crs.close();
        objectiveList.add("Others");

        listView.setAdapter(new ObjectivesAdapter(getActivity(), objectiveList));
        viewPager = (ViewPager) getActivity().findViewById(R.id.pager);

第一个

setTag（）

复选框如下：

checkBox.setTag(((Objectives)list.get(position)).getObjectiveID());

Cursor crsCheckObj = database.rawQuery("SELECT * FROM "+ ItemsTable.TABLE_PLAN_OBJECTIVE_MAP +" WHERE "
                            + ItemsTable.COLUMN_PLAN_OBJECTIVE_MAP_PLANID +"='"+ Info.getInstance().getPlanVisitID() +"'", null);
                    if(crsCheckObj.getCount() > 0){
                        while (crsCheckObj.moveToNext()){
                            if(((Integer) checkBox.getTag()) == crsCheckObj.getInt(crsCheckObj.getColumnIndex("objective_id"))){
                                checkBox.setChecked(true);
                            }
                        }

                    }
                    crsCheckObj.close();

那么你需要做的就是这样：

checkBox.setTag(((Objectives)list.get(position)).getObjectiveID());

Cursor crsCheckObj = database.rawQuery("SELECT * FROM "+ ItemsTable.TABLE_PLAN_OBJECTIVE_MAP +" WHERE "
                            + ItemsTable.COLUMN_PLAN_OBJECTIVE_MAP_PLANID +"='"+ Info.getInstance().getPlanVisitID() +"'", null);
                    if(crsCheckObj.getCount() > 0){
                        while (crsCheckObj.moveToNext()){
                            if(((Integer) checkBox.getTag()) == crsCheckObj.getInt(crsCheckObj.getColumnIndex("objective_id"))){
                                checkBox.setChecked(true);
                            }
                        }

                    }
                    crsCheckObj.close();

为此，您只需使用

checkbox.setChecked（true）

如果不起作用，请尝试以下操作：

checkbox.postDelayed(new Runnable() {
            @Override
            public void run() {
                checkbox.setChecked(true);
            }
        },100);

复选框。设置选中（布尔选中）？但要注意的是，当调用setChecked复选框时，会调用checkedchangedlistener，因此最好是设置ClickListener并手动调用Checkbox.unChecked（）是，我已经试过了，但我必须让循环知道哪个复选框设置为真，这就是我面临的问题。在getView中检查id…我不理解你的观点@Midslefko。我在getview方法中有ID，我只想将它们与复选框ID进行比较。你想说的一个例子对我来说是完美的。谢谢
