android - 隐藏 ListView 行而没有间距

Question

如何删除一个空格，即使我成功地隐藏了一行，但它在那里显示了一个空白。当 Status 等于“Awarded”时，它将隐藏一行，如下所示。帮我提前谢谢。

import android.app.Activity;
import android.graphics.Typeface;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;

public class ListViewAdapter extends BaseAdapter {

    Activity context;
    String ref[];
    String policy[];
    String natureofloss[];
    String make[];
    String registration[];
    String modelname[];
    String year[];
    String amount[];
    String status[];
    String quot_id[];

    public ListViewAdapter(Activity context, String[] ref, String[] policy,
            String[] natureofloss, String[] make, String[] registration,
            String[] modelname, String[] year, String[] amount,
            String[] status, String[] qout_id) {
        super();
        this.context = context;
        this.ref = ref;
        this.policy = policy;
        this.natureofloss = natureofloss;
        this.make = make;
        this.registration = registration;
        this.modelname = modelname;
        this.year = year;
        this.amount = amount;
        this.status = status;
        this.quot_id = qout_id;
    }

    public int getCount() {
        // TODO Auto-generated method stub

            holder = new ViewHolder();
            holder.ref = (TextView) convertView
                    .findViewById(R.id.tv_refpolicyno);

            holder.quot_id = (TextView) convertView
                    .findViewById(R.id.tv_quotid_clientqoutlist);

            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }

        if (!status[position].equals("Awarded")) {
            holder.ref.setText(ref[position]);
            holder.policy.setText("/" + policy[position]);
            holder.natureofloss.setText(natureofloss[position]);
            holder.make.setText(make[position]);

        } else {
            convertView.setVisibility(View.GONE);

        }

        return convertView;
    }

}

您需要创建适配器，它将使用 getCount() 返回非空项目的总数，然后继续获取数据的位置。

Ex. 您的列表位置为 1 - A 、2 - B、3 - null、4 - D、5 - null

调用 getCount 时返回 3。

此时 getView 在位置 1 上调用，您返回列表 [1] 中的项目。位置 3 上的 getView 返回列表[4](因为第 4 个位置不为空)，依此类推。
