How to clear item selection on listview

Question

I have set selection color to the listview item

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/rowTextView" 
android:layout_width="fill_parent" 
android:layout_height="wrap_content"
android:padding="10dp"
android:textColor="@drawable/text_selector"
android:textSize="16sp" >

But when the listview loses focus, the text color of the last item is stay on selected state.

enter image description here ->

I have tried the following code, but it's not working

View v = mainListView.getSelectedView();
v.setSelected(false);

Is there any way to clear the item selection?

Edit.

After checking with different platforms, the solution is still not working on some devices with Android 4.4.4(ex: Nexus 10), but it can work fine on Android 4.3 devices.

Thanks.

But when the listview loses focus, the text color of the last item is stay on selected state.

Please, remove the state_selected from your selector drawable xml and declare some choiceMode for it. My ListView declaration:

<ListView
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1"
    android:choiceMode="singleChoice"
    android:listSelector="@drawable/main_list_selector"
    ...

My selector for the list view (main_list_selector.xml):

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:drawable="@drawable/button_focused"/>

    <item android:state_pressed="true" android:drawable="@drawable/button_checked_background"/>
    <item android:state_activated="true" android:drawable="@drawable/button_checked_background"/>
</selector>

And row item layout:

<?xml version="1.0" encoding="utf-8"?>
<com.example.yourapp.ui.checkable.CheckableLinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">
    <CheckedTextView
        android:id="@+id/item_text_view"
        ...
        android:background="@drawable/row_item background"/>
</com.example.yourapp.ui.checkable.CheckableLinearLayout>

row_item background:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true" android:drawable="@drawable/button_checked_background"/>
    <item android:drawable="@android:color/transparent"/>
</selector>

As you see, I'm using CheckedTextView with background "row_item background" that has drawable state_checked, plus custon LinearLayout. LinearLayout code:

public class CheckableLinearLayout extends LinearLayout implements Checkable {
    private boolean checked = false;

    public CheckableLinearLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CheckableLinearLayout(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public boolean isChecked() {
        return this.checked;
    }

    @Override
    public void setChecked(boolean checked) {
        this.checked = checked;
        this.setSelected(this.checked);

        final int childsCount = getChildCount();
        for (int i = 0; i < childsCount; ++i) {
            View child = getChildAt(i);
            if (child instanceof Checkable) {
                ((Checkable) child).setChecked(checked);
            }
        }
    }

    @Override
    public void toggle() {
        setChecked(!this.checked);
    }
}

Some of this hidden android logic I've found in this https://stackoverflow.com/a/7425650/2133585 answer.

Try this :

v.clearChoices();
v.requestLayout();

EDIT :

According to this link ListView selection remains persistent after exiting choice mode , you can also try :

v.clearChoices();
for (int i = 0; i < v.getCount(); i++)
    v.setItemChecked(i, false);
v.post(new Runnable() {
    @Override
    public void run() {
        v.setChoiceMode(ListView.CHOICE_MODE_NONE);
    }
});

Because the above solution is still not working on some devices, so I find a solution to solve this problem.

private View mSelectedView; // the view has been selected


// set text color when the list view get focus or not
mainListView.setOnFocusChangeListener(new OnFocusChangeListener() {
    if(hasFocus) {
        if(mSelectedView != null && mSelectedView instanceof TextView)
            ((TextView)mSelectedView).setTextColor(getResources().getColorStateList(R.drawable.text_selector));
    } else {
        mSelectedView = mainListView.getSelectedView();
        if(mSelectedView != null && mSelectedView instanceof TextView)
            ((TextView)mSelectedView).setTextColor(getResources().getColor(R.color.default_color));
    }
});
