I have a listView in my project, I want to get background color changed when I click listItem. But when I click the one row, it changes many lines.
Here is my code for this function:
public View getView(int pos, View view, ViewGroup parent) {
mActivity = (Activity) this.getContext();
ListViewHolder holder;
if (view == null) {
LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.portfolio_row, null);
LinearLayout textViewWrap = (LinearLayout) view.findViewById(R.id.portfolio_text_wrap);
TextView text = (TextView) view.findViewById(R.id.portfolio_symbol);
holder = new ListViewHolder(textViewWrap, text);
} else
holder = (ListViewHolder) view.getTag();
PortfolioItem portfolioItem = getItem(pos);
}
But when I click the one row, it will change many lines.
I got the system.out.println for pos. I am supposed to get It should be 0 1 2 3 4 5 6 7 8 9 (# stands for position). What I get is a cycle now like this: 0 1 2 3 0 1 2 3 0 1
So if I click one , it will change all the same position. But if I don't click , just pull the listView down, the position are correct.Like 0----9.
Here is my code for item click:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
list = (ListView) root.findViewById(R.id.~~~);
list.setAdapter(adapter);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parentAdapter, View view, int position, long id) {
toggle(view, position);
}
});
}
What I want is getting the absolute position for it in listView. Please help me on this. Thanks!
UPDATES: Thanks for everyone's kindly answer. But I think you may misunderstand my question.
the getView changes the position. It means when you want to change number 9 row, it cannot be changed , because I only have 0 1 2 3
getView() and onCreateView() are in different class. The System.out.println("pos" + pos); in getView cannot get correct position.
The correct way should be 1 to last item. But when I click it , the number will be a cycle. the cycle number are how many rows the screen can display.
It is just like this link How ListView's recycling mechanism works
And I want to click to get only one and correct position. Thanks a lot.
Here is layout.xml:
<LinearLayout a:orientation="vertical"
a:layout_width="fill_parent"
a:layout_height="fill_parent">
<LinearLayout a:orientation="horizontal" a:layout_width="fill_parent" a:layout_height="wrap_content"
a:background="@color/onSelected">
<TextView a:text="@string/1" a:layout_weight="1" a:layout_width="fill_parent"
a:layout_height="fill_parent" a:layout_margin="10dp" a:textStyle="bold" a:id="@+id/0"/>
<TextView a:text="@string/2" a:layout_weight="1" a:layout_width="fill_parent"
a:layout_height="fill_parent" a:gravity="right" a:layout_margin="10dp" a:textStyle="bold"/>
<TextView a:text="@string/3" a:layout_weight="1" a:layout_width="fill_parent"
a:layout_height="fill_parent" a:gravity="right" a:layout_margin="10dp" a:textStyle="bold"/>
<TextView a:text="@string/4" a:layout_weight="1" a:layout_width="fill_parent"
a:layout_height="fill_parent" a:gravity="right" a:layout_margin="10dp" a:textStyle="bold"/>
<TextView a:text="@string/5" a:layout_weight="1" a:layout_width="fill_parent"
a:layout_height="fill_parent" a:gravity="right" a:layout_margin="10dp" a:textStyle="bold"/>
<TextView a:text="@string/6" a:layout_weight="1" a:layout_width="fill_parent"
a:layout_height="fill_parent" a:gravity="right" a:layout_margin="10dp" a:textStyle="bold"/>
<TextView a:text="@string/7" a:layout_weight="1" a:layout_width="fill_parent"
a:layout_height="fill_parent" a:gravity="right" a:layout_margin="10dp" a:textStyle="bold"/>
</LinearLayout>
<android.support.v4.widget.SwipeRefreshLayout a:layout_width="fill_parent"
a:layout_height="fill_parent"
a:id="@+id/portfolios">
<ListView a:layout_width="fill_parent" a:layout_height="fill_parent" a:id="@+id/8" />
</android.support.v4.widget.SwipeRefreshLayout>
</LinearLayout>
UPDATES2: Here is listViewHolder:
public class ListViewHolder {
private LinearLayout textViewWrap;
private TextView textView;
public ListViewHolder(LinearLayout textViewWrap, TextView textView) {
super();
this.textViewWrap = textViewWrap;
this.textView = textView;
}
public TextView getTextView() {
return textView;
}
public void setTextView(TextView textView) {
this.textView = textView;
}
public LinearLayout getTextViewWrap() {
return textViewWrap;
}
public void setTextViewWrap(LinearLayout textViewWrap) {
this.textViewWrap = textViewWrap;
}
}
Here set the fragment
class fragment{
list = (ListView) root.findViewById(R.id.123);
list.setAdapter(adapter);
}
In fragment class I have listItemClickListener and in the adapter I have the getView function
