我一直在尝试在列表片段中实现两个列表视图,我在我的 xml 中声明了两个列表视图,并尝试在 java 文件中设置两组单独的数据,但是用于第一个 lisview 的列表视图数据被覆盖第二。
我如何能够使用下面的代码将其指向正确的列表视图?
列表应该去的片段的Java:
package com.owais.shopsellswap;
import java.util.ArrayList;
import java.util.HashMap;
import android.os.Bundle;
import android.support.v4.app.ListFragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.SimpleAdapter;
public class Fragment_My_Profile extends ListFragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View myProfileView = inflater.inflate(R.layout.fragment_my_profile, container, false);
return myProfileView;
}
// Store Arralist as hashmaps for the listview
ArrayList<HashMap<String,String>> list = new ArrayList<HashMap<String,String>>();
ArrayList<HashMap<String,String>> list2 = new ArrayList<HashMap<String,String>>();
// SimpleAdapter (listViewAdapter) links the array to the listview
private SimpleAdapter listViewAdapter;
private SimpleAdapter listViewAdapter2;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//HashMap links each line of data to the correct TextView
HashMap<String,String> item;
for(int i=0;i<userInfo.length;i++){
item = new HashMap<String,String>();
item.put( "line1", userInfo[i][0]);
item.put( "line2", userInfo[i][1]);
list.add( item );
}
HashMap<String,String> item2;
for(int i=0;i<ListingsArray.length;i++){
item2 = new HashMap<String,String>();
item2.put( "line1", ListingsArray[i][0]);
item2.put( "line2", ListingsArray[i][1]);
item2.put( "line3", ListingsArray[i][2]);
list2.add( item2 );
}
listViewAdapter = new SimpleAdapter(getActivity(), list,
R.layout.listview_layout_1,
new String[] { "line1","line2" },
new int[] {R.id.line_a, R.id.line_b});
listViewAdapter2 = new SimpleAdapter(getActivity(), list2,
R.layout.listview_layout_3,
new String[] { "line1","line2", "line3" },
new int[] {R.id.line_a1, R.id.line_b1, R.id.line_c1});
setListAdapter(listViewAdapter);
setListAdapter(listViewAdapter2);
}
private String[][] userInfo =
{{"User","Dummy"},
{"Email Address","Dummy@dummymail.com"},
{"User Type","Staff"},
{"Contact Number","07111111111"}};
private String[][] ListingsArray =
{{"audi a3","brand new audi a3 with alloywheels, cd player", "£11000"},
{"HTC One x","brand new android smartphone", "£450"},
{"Acer Laptop","Acer Laptop with windows 7", "£300"},
{"Sunglass","Oakley Sunglasses in great condition", "£100"}};
}
片段的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:orientation="vertical" >
<TextView
android:id="@+id/textView2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@color/lightgrey"
android:text="@string/userInfoHeader"
android:textSize="15sp"
android:textStyle="bold" />
<ListView
android:id="@+id/android:list"
android:layout_width="fill_parent"
android:layout_height="184dp"
android:layout_alignParentLeft="true"
android:layout_below="@+id/textView2" >
</ListView>
<TextView
android:id="@+id/textView3"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/android:list"
android:background="@color/lightgrey"
android:text="@string/listingsHeader"
android:textSize="15sp"
android:textStyle="bold" />
<ListView
android:id="@+id/android:list2"
android:layout_width="fill_parent"
android:layout_height="184dp"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true" >
</ListView>
</RelativeLayout>
列表视图还为每个列表使用自定义布局。
