我无法使用 listView 获得页眉/页脚。我尝试了很多方法,但我不知道我哪里出错了。请在此处找到基本代码。
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/listView"
android:layout_gravity="center"/>
</LinearLayout>
header.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:padding="5dip">
<Button android:id="@+id/previous"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_centerHorizontal="true" />
</RelativeLayout>
MainActivity.java
package com.example.listview;
import java.util.ArrayList;
import android.os.Bundle;
import android.app.Activity;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.RelativeLayout;
import android.widget.Toast;
public class MainActivity extends Activity {
private static final String[] lakes = {
"Superior",
"Victoria",
"Huron",
"Michigan",
"Tanganyika",
"Baikal",
"Great Bear Lake",
"Great Slave Lake",
"Erie",
"Winnipeg",
"Ontario",
"Balkhash",
"Ladoga",
"Vostok",
"Onega",
"Titicaca",
"Nicaragua",
"Athabasca" };
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LayoutInflater inflater = this.getLayoutInflater();
RelativeLayout listFooterView = (RelativeLayout)inflater.inflate(R.layout.header, null);
ListView listView = (ListView)findViewById(R.id.listView);
listView.addFooterView(listFooterView);
ArrayAdapter<String> adapter =
new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, lakes);
listView.setAdapter(adapter);
}
}
如果我删除 listView.addFooterView(listFooterView); ,应用程序工作并显示 listView。但是,包含此语句会使应用程序崩溃。请让我知道这个问题的解决方案。
