Question

我将图像和文本链接在一起以显示在片段中。一切都很好，除了每个项目下面出现的这条透明线。此行显示调用片段的活动的布局。我怎么能让这个fundraiser.xml占用所有的屏幕，无论我的列表中有多少项目以及如何在每个项目之后摆脱该行？我上传了一张图片，以便更好地解释我的问题http://i.imgur.com/7F0EoHy.png

这是我的fundraiser.xml文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout         
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#000000" >


    <LinearLayout

            android:background="#000000"
            android:layout_weight="1">
        </ImageView>
        <TextView
            android:id="@+id/label"

这是我的fundraiserfragmen文件

package com.github.devnied.emvnfccard.fragment;
import android.os.Bundle;
import android.support.v4.app.ListFragment;
import android.view.View;
import android.widget.ListView;
import android.widget.Toast;

 import com.github.devnied.emvnfccard.adapter.MobileArrayAdapter;

public class FundraiserFragment extends ListFragment {

static final String[] values = new String[] {"Landsbjörg", "Blái  Naglinn", "SÁÁ Álfurinn"};

@Override
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setListAdapter(new MobileArrayAdapter(getActivity(),values));
}

@Override
public void onListItemClick(ListView l, View v, int position, long ID) {
    String value = (String) getListAdapter().getItem(position);
    Toast.makeText(getActivity(), value, Toast.LENGTH_SHORT).show();
}
}

这是我的MobileArrayAdapter文件

package com.github.devnied.emvnfccard.adapter;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;

import com.github.devnied.emvnfccard.R;

public class MobileArrayAdapter extends ArrayAdapter<String> {
private final Context context;
private final String[] values;

public MobileArrayAdapter(Context context, String[] values) {
    super(context, R.layout.fundraiser, R.id.label, values);
    this.context = context;
    this.values = values;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    View rowView = inflater.inflate(R.layout.fundraiser, parent, false);
    TextView textView = (TextView) rowView.findViewById(R.id.label);
    ImageView imageView = (ImageView) rowView.findViewById(R.id.logo);
    textView.setText(values[position]);

    // Change icon based on name
    String s = values[position];

    System.out.println(s);

    if (s.equals("Landsbjörg")) {
        imageView.setImageResource(R.drawable.landsbjorg);
    } else if (s.equals("Blái Naglinn")) {
        imageView.setImageResource(R.drawable.blai);
    } else if (s.equals("SÁÁ Álfurinn")) {
        imageView.setImageResource(R.drawable.saa_alfurinn);
    } else {
        imageView.setImageResource(R.drawable.ic_launcher);
    }

    return rowView;

}
}

Answer 1

android:divider = "@null"正如天网在评论中所说，或者如果你想以编程方式进行，你应该这样做： getListView().setDivider(null);方法中的onActivityCreated()。

注意：在制作此

时没有看到其他答案

Answer 2

使用setDividerHeight

@Override
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    getListView().setDividerHeight(0);
    setListAdapter(new MobileArrayAdapter(getActivity(),values));
}
