Usage

From source file:android.support.v7.widget.DropDownListView.java

private void setPressedItem(View child, int position, float x, float y) {
    mDrawsInPressedState = true;/*from  ww w.  j  av  a 2 s  . c o m*/

    // Ordering is essential. First, update the container's pressed state.
    if (Build.VERSION.SDK_INT >= 21) {
        drawableHotspotChanged(x, y);
    }
    if (!isPressed()) {
        setPressed(true);
    }

    // Next, run layout to stabilize child positions.
    layoutChildren();

    // Manage the pressed view based on motion position. This allows us to
    // play nicely with actual touch and scroll events.
    if (mMotionPosition != INVALID_POSITION) {
        final View motionView = getChildAt(mMotionPosition - getFirstVisiblePosition());
        if (motionView != null && motionView != child && motionView.isPressed()) {
            motionView.setPressed(false);
        }
    }
    mMotionPosition = position;

    // Offset for child coordinates.
    final float childX = x - child.getLeft();
    final float childY = y - child.getTop();
    if (Build.VERSION.SDK_INT >= 21) {
        child.drawableHotspotChanged(childX, childY);
    }
    if (!child.isPressed()) {
        child.setPressed(true);
    }

    // Ensure that keyboard focus starts from the last touched position.
    positionSelectorLikeTouchCompat(position, child, x, y);

    // This needs some explanation. We need to disable the selector for this next call
    // due to the way that ListViewCompat works. Otherwise both ListView and ListViewCompat
    // will draw the selector and bad things happen.
    setSelectorEnabled(false);

    // Refresh the drawable state to reflect the new pressed state,
    // which will also update the selector state.
    refreshDrawableState();
