我有 4 组联系人(类型 1、2、3、无)。我想为 Type1、2、3 加载不同的图像 3,如果联系人属于无,那么列表视图不应包含任何图像。这是我的代码
@Override
public View getView(int position, View convertView,
ViewGroup parent) {
// return super.getView(position, convertView, parent);
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater) ContactsListActivity.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.contacts_list_row_view, null);
}
try {
contactsData = (ContactsItem) getItem(position);
} catch (Exception e) {
}
if (null != contactsData){
final CheckBox contactsSelectedCheck = (CheckBox) v.findViewById(R.id.contact_selected_check);
TextView contactNameText = (TextView) v.findViewById(R.id.contact_name_text);
TextView contactNumberText = (TextView) v.findViewById(R.id.contact_number_text);
ImageView contactImage = (ImageView) v.findViewById(R.id.contact_image);
contactNameText.setText(contactsData.getContactName());
contactNumberText.setText(contactsData.getContactNumber());
if(contactNameText != null && contactNumberText != null){
if(contactsData.getContactProfileType() == DBConstants.TYPE_1){ contactImage.setImageDrawable(getResources().getDrawable(R.drawable.icon_1));
} else if(contactsData.getContactProfileType() == DBConstants.TYPE_2){ contactImage.setImageDrawable(getResources().getDrawable(R.drawable.icon_2));
} else if(contactsData.getContactProfileType() == DBConstants.TYPE_3){ contactImage.setImageDrawable(getResources().getDrawable(R.drawable.icon_3));
}else{
}
}
if (selectedContactsTable.containsKey(contactsData.getContactNumber())) {
contactsSelectedCheck.setChecked(true);
} else {
contactsSelectedCheck.setChecked(false);
}
contactsSelectedCheck.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (contactsSelectedCheck.isChecked()) {
LinearLayout r_layout = (LinearLayout) v.getParent();
TextView contactName = (TextView) r_layout.getChildAt(1);
TextView contactNumber = (TextView) r_layout.getChildAt(2);
selectedContactsTable.put(contactNumber.getText().toString(), contactName.getText().toString());
}else{
LinearLayout r_layout = (LinearLayout) v.getParent();
TextView contactNumber = (TextView) r_layout.getChildAt(2);
selectedContactsTable.remove(contactNumber.getText().toString());
}
}
});
}
return v;
}
}
问题是如果我将一些联系人分配给类型 1 对应的图像,这种类型加载正确,但是当我滚动列表时,相同的图像也会加载到一些未分配的图像,我的代码有什么问题,请告诉我
