Selector, in listview (swipe-listview) row, stays in state pressed after re-instanciating the adapter

问题

I have a listview and the row's layout has a child with the background set to the following selector :

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true">
    <shape android:shape="rectangle">
        <solid android:color="@color/pressed_panel" />
        <corners android:radius="@dimen/rounded_panel_corners" />
    </shape>
</item>
<item>
    <shape android:shape="rectangle">
        <solid android:color="#ffffff" />
        <corners android:radius="@dimen/rounded_panel_corners" />
    </shape>
</item>

And now this scenario happens:

I instantiate the adapter and set it to the listview, with an underlying list, let's say model A (inside a ListFragment)
I press on the first row (happens for other row also), and only while pressed, the selector stays in the pressed state, showing some gray color, duh!
I select from a menu some item and that triggers: creating a new instance of the adaptor, with list model B, and apply it to the listview.
And now the problem: the first row has the selector in the pressed state

More info: @Questions raised by Abhishek V in comment: 1. Background is set to row layout's child and not the row layout itself right? Right! Here is the layout, the selector is set to the relative with id "container_conversation"

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:descendantFocusability="blocksDescendants"
android:orientation="vertical">

<CheckBox
    android:id="@+id/checkbox_select_row"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_vertical"
    android:layout_marginLeft="18dp"
    android:button="@drawable/checkbox_round_selector"
    android:focusable="false"
    android:clickable="true"
    android:padding="8dp"/>

<FrameLayout
    android:id="@+id/row"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:descendantFocusability="blocksDescendants"
    android:orientation="vertical"
    >

    <RelativeLayout
        android:id="@+id/back"
        android:layout_width="wrap_content"
        android:layout_height="82dp"
        android:layout_gravity="right"
        android:layout_marginBottom="4dp"
        android:layout_marginRight="9dp"
        android:layout_marginTop="4dp">
            <SomeViews>
    </RelativeLayout>

    <FrameLayout
        android:id="@+id/front"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:visibility="visible"
        tools:visibility="visible">

        <RelativeLayout
            android:id="@+id/container_conversation"
            android:layout_width="match_parent"
            android:layout_height="82dp"
            android:layout_marginBottom="4dp"
            android:layout_marginLeft="9dp"
            android:layout_marginRight="9dp"
            android:layout_marginTop="4dp"
            android:background="@drawable/white_rounded_panel">
                <SomeViews>
        </RelativeLayout>

        <View
            android:id="@+id/unread_indicator"
            android:layout_width="8dp"
            android:layout_height="8dp"
            android:layout_gravity="center_vertical"
            android:layout_marginLeft="5dp"
            android:background="@drawable/orange_circle"
            android:visibility="gone"
            tools:visibility="visible" />
    </FrameLayout>
</FrameLayout>

2) Click/touch listener is set to row layout or it's child? Child 3) Which listener you are using, is it onClick, onTouch or onItemClick? The listview is actually copied from the library android-swipelistview https://github.com/47deg/android-swipelistview . The click that does the damage is set as follows:

frontView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            swipeListView.onClickFrontView(downPosition);
        }
    });

and this click goes notifying this listener

BaseSwipeListViewListener swipeListener = new BaseSwipeListViewListener() {
    @Override
    public void onClickFrontView(int position) {

    }//...

Thank you!

回答1:

The issue you are facing has been reported here https://github.com/47deg/android-swipelistview/issues/41.

As per the cooment by @strgev in that thread, the fix is to -

edit class SwipeListViewTouchListener by adding the line below to onTouch method:

....
case MotionEvent.ACTION_UP: {
view.onTouchEvent(motionEvent);
...

can you try that?

回答2:

Try with clearChoices and notifyDataSetChanged:

yourListView.clearChoices();
yourListView.getAdapter().notifyDataSetChanged();

回答3:

It may be a mutate problem. Try to assign the background to the row programmatically by first calling mutate() on the drawable.

First, obtain a Drawable instance from your custom selector-drawable, then invoke mutate() on it and finally assign the drawable as row's background:

Drawable selector = getResources().getDrawable(R.drawable.your_selector)
selector.mutate();
//...
row.setBackground(selector);
