Android getView() 没有被正确调用？

Question

由于某种原因，getView() 方法没有被完全调用。它应该被调用 10 次。但这不是……

@Override 
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    res = getResources();
    searchField = (EditText) findViewById(R.id.EditText01);
    list = (ListView) findViewById(android.R.id.list);
//  button = (Button)findViewById(R.id.btnFriendList);

    friendList = new ArrayList<Friend>();

    nameBlock = res.getStringArray(R.array.names);
    descBlock = res.getStringArray(R.array.descriptions);
    //imageBlock = res.getIntArray(R.array.images);

    int size = nameBlock.length;
    for(int i = 0 ; i < size; i++) {
        Log.d("FREINDADD", "Freind Added" + i);
        friendList.add(new Friend(nameBlock[i], descBlock[i], imageBlock[i]));
    }
    Log.i("Application", "Application started succesfully...");

    setListAdapter(new VirtuAdapter(this));

    searchField.addTextChangedListener(new TextWatcher()
    {
        @Override public void afterTextChanged(Editable s) {}
        @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) {}
        @Override public void onTextChanged(CharSequence s, int start, int before, int count)
        {
            friendList.clear();
            textlength = searchField.getText().length();

            for (int i = 0; i < nameBlock.length; i++)
            {
                if (textlength <= nameBlock[i].length())
                {
                    if(nameBlock[i].toLowerCase().contains(searchField.getText().toString().toLowerCase().trim())) {
                        Log.i("VirtuFriendList", "List recyling in process... ");
                        friendList.add(new Friend(nameBlock[i], descBlock[i], imageBlock[i]));
                    }
                  }
            }
            AppendList(friendList);
            }
    });


}
public void AppendList(ArrayList<Friend> freind) {
    setListAdapter(new VirtuAdapter(this));
} 
public class VirtuAdapter extends BaseAdapter
{
    Activity content;
    public VirtuAdapter(Activity context)
    {
        this.content = context;
    }
    @Override
    public int getCount()
    {
        return friendList.size();
    }
    @Override
    public Object getItem(int position)
    {
        return friendList.get(position);
    }
    @Override
    public long getItemId(int position)
    {
        return friendList.size();
    }
    class ViewHolder {
        TextView myTitle;
        TextView myDescription;
        ImageView myImage;

        ViewHolder(View view) {
            myImage = (ImageView)view.findViewById(R.id.imageview);
            myTitle = (TextView)view.findViewById(R.id.title);
            myDescription = (TextView)view.findViewById(R.id.mutualTitle);
        }
    }
    @Override
    public View getView(int position, View view, ViewGroup parent)
    {
        View row = view;
        ViewHolder holder = null;

        if(row == null) 
        {
            // If it is visible to the user, deploy the row(s) - allocated in local memory
            LayoutInflater inflater = (LayoutInflater)content .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            row = inflater.inflate(R.layout.search_list_item, parent, false);
            holder = new ViewHolder(row);
            row.setTag(holder);
            Log.d("VIRTU", "Row deployed...");
        }
        else 
        {
            // Recycle the row if it is not visible to to the user - store in local memory
            holder = (ViewHolder)row.getTag();
            Log.d("VIRTU", "Row recycled...");
        }
        Friend temp = friendList.get(position);

        // Set the resources for each component in the list
        holder.myImage.setImageResource(temp.getImage());
        holder.myTitle.setText(temp.getName());
        holder.myDescription.setText(temp.getDesc());

    return row;
    }
}

我在每个字符串数组中有 10 个元素。结果，应该在 ListView 中创建 10 个元素...但是，只有 5 个占上风...

有人有什么建议吗？ 日志猫：

试试这个方法，希望能帮助你解决问题。

public class VirtuAdapter extends BaseAdapter
    {
        private Context content;
        private ArrayList<Friend> friendList;
        public VirtuAdapter(Context context,ArrayList<Friend> friendList)
        {
            this.content = context;
            this.friendList = friendList;
        }
        @Override
        public int getCount()
        {
            return friendList.size();
        }
        @Override
        public Object getItem(int position)
        {
            return friendList.get(position);
        }
        @Override
        public long getItemId(int position)
        {
            return friendList.size();
        }
        class ViewHolder {
            TextView myTitle;
            TextView myDescription;
            ImageView myImage;
        }
        @Override
        public View getView(int position, View view, ViewGroup parent)
        {
            ViewHolder holder;
            if(view == null)
            {
                holder = new ViewHolder();
                view = LayoutInflater.from(content).inflate(R.layout.search_list_item, null, false);
                holder.myImage = (ImageView)view.findViewById(R.id.imageview);
                holder.myTitle = (TextView)view.findViewById(R.id.title);
                holder.myDescription = (TextView)view.findViewById(R.id.mutualTitle);
                view.setTag(holder);
            }
            else
            {
                holder = (ViewHolder)view.getTag();
            }
            holder.myImage.setImageResource(friendList.get(position).getImage());
            holder.myTitle.setText(friendList.get(position).getName());
            holder.myDescription.setText(friendList.get(position).getDesc());

            return view;
        }
    }
