我正在尝试实现自定义列表视图，但在 ItemClickListener 上不起作用。我有活动： Pregled 并且此活动必须从 Activty 扩展，而不是从 ListActivity 扩展，因为我想添加一些其他功能。我使用自定义的 ListView。代码是这样的：
list_item_choice.xml：
<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="@android:color/white"
android:gravity="bottom" >
<RelativeLayout
android:id="@+id/relativeLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@android:color/white" >
<ImageView
android:id="@+id/icon"
android:layout_width="wrap_content"
android:layout_height="60dp"
android:layout_toLeftOf="@+id/name"
/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="@+id/icon"
android:orientation="vertical" >
<TextView
android:id="@+id/name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#003366"
/>
</LinearLayout>
</RelativeLayout>
</LinearLayout>
activity_pregled.xml：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:id="@+id/ChoiceList"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1"
>
</ListView>
</LinearLayout>
Pregled.java：
公共类 Pregled 扩展 Activity {
ListView choiceList;
ArrayList<Choice> choice;
AdapterView.AdapterContextMenuInfo info;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_pregled_main);
setTitle("Преглед");
choiceList = (ListView) findViewById(R.id.ChoiceList);
choice = new ArrayList<Choice>();
Choice c;
c = new Choice();
c.setIcon(R.drawable.coffee);
c.setName("Кафулиња");
choice.add(c);
c = new Choice();
c.setIcon(R.drawable.nokniklubovi);
c.setName("Ноќни клубови");
choice.add(c);
c = new Choice();
c.setIcon(R.drawable.pivnici);
c.setName("Пивници");
choice.add(c);
c = new Choice();
c.setIcon(R.drawable.restorani);
c.setName("Ресторани");
choice.add(c);
c = new Choice();
c.setIcon(R.drawable.nacionalnirestorani);
c.setName("Национални ресторани");
choice.add(c);
c = new Choice();
c.setIcon(R.drawable.hoteli);
c.setName("Хотели");
choice.add(c);
c = new Choice();
c.setIcon(R.drawable.znamenitosti);
c.setName("Знаменитости");
choice.add(c);
choiceList.setAdapter(new CustomAdapter(choice, this));
choiceList.setClickable(true);
choiceList
.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
if (arg0.getSelectedItemPosition() == 0) {
// кафулиња
} else if (arg0.getSelectedItemPosition() == 1) {
// ноќни клубови
} else if (arg0.getSelectedItemPosition() == 2) {
// пивници
} else if (arg0.getSelectedItemPosition() == 3) {
// ресторани
Intent k = new Intent(Pregled.this, Restorani.class);
startActivity(k);
} else if (arg0.getSelectedItemPosition() == 4) {
// национални ресторани
} else if (arg0.getSelectedItemPosition() == 5) {
// хотели
Intent k = new Intent(Pregled.this, Hoteli.class);
startActivity(k);
} else if (arg0.getSelectedItemPosition() == 6) {
// знаменитости
Intent k = new Intent(Pregled.this,
Znamenitosti.class);
startActivity(k);
}
}
});
......
和自定义适配器：
public class CustomAdapter extends BaseAdapter {
private ArrayList<Choice> _data;
Activity _c;
CustomAdapter(ArrayList<Choice> data, Activity c) {
_data = data;
_c = c;
}
public int getCount() {
// TODO Auto-generated method stub
return _data.size();
}
public Object getItem(int position) {
// TODO Auto-generated method stub
return _data.get(position);
}
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater) _c
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.list_item_choice, null);
}
ImageView image = (ImageView) v.findViewById(R.id.icon);
TextView fromView = (TextView) v.findViewById(R.id.name);
Choice msg = _data.get(position);
image.setImageResource(msg.icon);
fromView.setText(msg.name);
return v;
}
}
