我使用联系人同步制作了一个应用程序。我列出了以下联系信息,包括照片、姓名和电话号码。我成功地在自定义ListView中列出了所有这些内容,但我无法单击ListView。它看起来像被锁定,无法单击它。
但我对另一个活动做了同样的程序。使用自定义ListView但我可以单击此视图并且它工作正常。
问题是什么?这是我的示例编码:
ListView settingsList = (ListView) findViewById(R.id.manage_track_listView);
ArrayList<ContactList> MySettingsList = new ArrayList<ContactList>();
ContactList setting1 = new ContactList("contact name 1", "Number 1", null);
ContactList setting2 = new ContactList("contact name 2", "Number 2", null);
ContactList setting3 = new ContactList("contact name 3", "Number 3", null);
MySettingsList.add(setting1);
MySettingsList.add(setting2);
MySettingsList.add(setting3);
ContactList list[] = new ContactList[MySettingsList.size()];
for(int i=0;i<MySettingsList.size();i++) {
ContactList mySettings = MySettingsList.get(i);
list[i] = new ContactList(mySettings.getName(), mySettings.getNumber(), mySettings.getImageIcon());
}
ContactListAdapter adapter = new ContactListAdapter(this, R.layout.manage_track_list_custom_view, list);
settingsList.setAdapter(adapter);
System.out.println("before listener");
settingsList.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// TODO Auto-generated method stub
System.out.println("Clicked " + position);
}
});
System.out.println("after listener");
这里的 ContactList 是一个类,它具有联系人姓名、号码和 imageBlob 的 byte[]。如果图像为空,我将默认 ic_launcher 设置为联系人图像。适配器类是:
public class ContactListAdapter extends ArrayAdapter<ContactList> {
Context context;
int layoutResourceId;
ContactList objects[] = null;
View row;
public ContactListAdapter(Context context, int layoutResourceId, ContactList[] objects) {
super(context, layoutResourceId, objects);
// TODO Auto-generated constructor stub
this.context = context;
this.layoutResourceId = layoutResourceId;
this.objects = objects;
System.out.println(objects[1].getName());
System.out.println(objects[1].getNumber());
System.out.println(objects[1].getImageIcon());
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
row = convertView;
final ContactListHolder holder;
if ( row == null ) {
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
row = inflater.inflate(layoutResourceId, parent, false);
holder = new ContactListHolder();
holder.image = (ImageView) row.findViewById(R.id.contactImage);
holder.name = (TextView) row.findViewById(R.id.contactName);
holder.number = (TextView) row.findViewById(R.id.contactNumber);
holder.check = (CheckBox) row.findViewById(R.id.selectedContact);
row.setTag(holder);
} else {
holder = (ContactListHolder)row.getTag();
}
ContactList contact = objects[position];
if(contact.imageIcon != null) {
Bitmap imgBitmap = BitmapFactory.decodeByteArray(contact.imageIcon, 0, contact.imageIcon.length);
holder.image.setImageBitmap(imgBitmap);
} else {
holder.image.setImageResource(R.drawable.ic_launcher);
}
holder.name.setText(contact.name);
holder.number.setText(contact.number);
holder.check.setChecked(objects[position].isSelected());
return row;
}
static class ContactListHolder {
ImageView image;
TextView name;
TextView number;
CheckBox check;
}
}
我有 100 多个联系人,所以只添加了 3 个对象。在此联系人列表中,我成功收到联系人图片、姓名、号码。
ListView无法点击是什么问题?我希望你们中的任何人都会指导我。提前致谢。
谢谢大家。现在只需添加android:focusable="false"
我的所有子视图即可得到结果。感谢您的指导。
