小编use*_*092的帖子

我知道人们已经提出了这个问题,但我遵循了所有的答案,我仍然遇到同样的问题.我有两个脚本一个是片段管理器(IngredientsActivity),另一个是片段(OtherList).代码如下

IngredientsActivity

import java.util.ArrayList;

import android.app.ActionBar;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;



public class IngredientsActivity extends FragmentActivity implements ActionBar.TabListener {

    private static final String STATE_SELECTED_NAVIGATION_ITEM = "selected_navigation_item";

    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.check_list);

        // Set up the action bar.
        final ActionBar actionBar = getActionBar();
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

        // For each of the sections in the app, add a tab to the action bar.
        actionBar.addTab(actionBar.newTab().setText("Alcahol").setTabListener(this));
        actionBar.addTab(actionBar.newTab().setText("Juice").setTabListener(this));
        actionBar.addTab(actionBar.newTab().setText("Other").setTabListener(this)); …

我正在使用一个片段来创建一个ListView填充CheckBoxes.我尽力找到基于其他问题的解决方案,但我似乎无法修复它.当我运行脚本而不使用:

convertView.getTag();

我的应用程序运行正常,但列表中项目的位置不保存.视图项目跳转.但是,当我使用该方法时,我收到一个错误.日志猫说:
