expand and collapse problem
Hi, I have 2 cardviews. If I click the first card view, I would like to expand this card view and to collapse the second card view. By the same way, if I click the second card view, I would like to expand this card view and to collapse the first card view,
Unfortunately, the card view that I want to collapse is disappearing from the screen. and it is not reachable again. please help me for solving this problem.
card1 = root.findViewById(R.id.x1); card2 = root.findViewById(R.id.x2);
card1.setOnExpandedListener(new ExpandableCardView.OnExpandedListener() {
@Override
public void onExpandChanged(View v, boolean isExpanded) {
if (isExpanded)
card2.collapse();
}
});
card2.setOnExpandedListener(new ExpandableCardView.OnExpandedListener() {
@Override
public void onExpandChanged(View v, boolean isExpanded) {
if(isExpanded)
card1.collapse();
}
});
Hi @princeivankent, I solved this problem. You need to expand cardviews by giving a delay at first. I am adding code below.
private void cardViewListeners() {
try {
new Handler().postDelayed(() -> binding.cardView1.expand(), 100);
new Handler().postDelayed(() -> binding.cardView2.expand(), 100);
binding.cardView1.setOnExpandedListener((v, isExpanded) -> {
if (isExpanded) {
new Handler().postDelayed(() -> {
binding.cardView2.collapse();
}, 100);
}
});
binding.cardView2.setOnExpandedListener((v, isExpanded) -> {
if (isExpanded) {
new Handler().postDelayed(() -> {
binding.cardView1.collapse();
}, 30);
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
handed this, check the card is expanded before the collapse
if (card2.isExpanded) {
card2.collapse()
}`
