我有两个需要处理和显示的列表,我使用了以下技术 -
我从两个来源获取数据,处理它并拥有2个自定义适配器,它们获取数据并将其放在relvant视图中。
但是我只能查看一个列表(视图xml顶部的列表) - 而不是另一个列表,
有人可以帮我解决这个问题。它让我疯了。
主要活动代码belwo:
public class TestList extends Activity {
private final static String TAG = "ListSample";
private List<String> items;
private List<String> items2;
private CustomTeamListAdapter m_adapter;
private CustomTeamListAdapterTwo t_adapter;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
items = new ArrayList<String>();
for (int i = 0; i < 20; i++) {
items.add(i + "|||>>");
}
ListView list = (ListView) findViewById(R.id.customlist);
this.m_adapter = new CustomTeamListAdapter(this, R.layout.listitem,
(ArrayList<String>) items);
list.setAdapter(m_adapter);
/******************************************************************************/
items2 = new ArrayList<String>();
for (int i = 0; i < 20; i++) {
items2.add(i + ">>----");
}
ListView list_two = (ListView) findViewById(R.id.customlisttwo);
this.t_adapter = new CustomTeamListAdapterTwo(this, R.layout.listitem,
(ArrayList<String>) items2);
list_two.setAdapter(t_adapter);
}
private class CustomTeamListAdapter extends ArrayAdapter<String> {
private ArrayList<String> items;
public CustomTeamListAdapter(Context context, int textViewResourceId,
ArrayList<String> items) {
super(context, textViewResourceId, items);
this.items = items;
}
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.listitem, null);
String o = items.get(position);
if (o != null) {
TextView tt = (TextView) v.findViewById(R.id.sampletext);
tt.setText(o + "FirstSet");
tt.setId(position);
}
return v;
}
}
private class CustomTeamListAdapterTwo extends ArrayAdapter<String> {
private ArrayList<String> items;
public CustomTeamListAdapterTwo(Context context, int textViewResourceId,
ArrayList<String> items) {
super(context, textViewResourceId, items);
this.items = items;
}
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.listitem, null);
String o = items.get(position);
if (o != null) {
TextView tt = (TextView) v.findViewById(R.id.sampletext);
tt.setText(o + "SecondSet");
tt.setId(position);
}
return v;
}
}
}
下面的主要布局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:id="@+id/customlisttwo"
android:layout_width="fill_parent" android:layout_height="wrap_content" />
<TextView android:id="@+id/randomtext" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:background="#CCCCCC"
android:text="Random Text" />
<ListView android:id="@+id/customlist" android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
项目布局
<?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:id="@+id/customlisttwo"
android:layout_width="fill_parent" android:layout_height="wrap_content" />
<TextView android:id="@+id/randomtext" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:background="#CCCCCC"
android:text="Random Text" />
<ListView android:id="@+id/customlist" android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
提前感谢您的想法

尝试使用Mark Murphy的https://github.com/commonsguy/cwac-merge合并适配器。您无法在同一活动中拥有两个列表视图。您可以在两个布局之间添加该文本视图。
