How to change textview text on cardview click?

I think the issue was by ths following , You have to override the onBindViewHolder() method then implement as below.
code :
Override 
public void  onBindViewHolder(RecyclerViewHolder holder, int position) {
   Model model = getItem(position);
   holder.bind(model);
}

public class RecyclerViewHolder extends RecyclerView.ViewHolder {

  public final TextView title;
  public final TextView product;

  public RecyclerViewHolder(View itemView) {
    super (itemView);
    title    = itemView.findViewById(R.id.title);
    product  = itemView.findViewById(R.id.product);
  }

  public void bind(final Model model){
    itemView.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
       title.setText(model.getText());
      }
    });
  }
}

I wish this help you I do the same thing with following structure :
first of all create AnimationHelper class like following :
code :
public class AnimationHelper {
    public static void expand(final View v) {
        v.measure(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
        final int targetHeight = v.getMeasuredHeight();

        v.getLayoutParams().height = 0;
        v.setVisibility(View.VISIBLE);
        Animation a = new Animation() {
            @Override
            protected void applyTransformation(float interpolatedTime, Transformation t) {
                v.getLayoutParams().height = interpolatedTime == 1
                        ? LinearLayout.LayoutParams.WRAP_CONTENT
                        : (int) (targetHeight * interpolatedTime);
                v.requestLayout();
            }

            @Override
            public boolean willChangeBounds() {
                return true;
            }
        };

        // 1dp/ms
        a.setDuration((int) (targetHeight / v.getContext().getResources().getDisplayMetrics().density));
        v.startAnimation(a);
    }

    public static void collapse(final View v) {
        final int initialHeight = v.getMeasuredHeight();

        Animation a = new Animation() {
            @Override
            protected void applyTransformation(float interpolatedTime, Transformation t) {
                if (interpolatedTime == 1) {
                    v.setVisibility(View.GONE);
                } else {
                    v.getLayoutParams().height = initialHeight - (int) (initialHeight * interpolatedTime);
                    v.requestLayout();
                }
            }

            @Override
            public boolean willChangeBounds() {
                return true;
            }
        };
        // 1dp/ms
        a.setDuration((int) (initialHeight / v.getContext().getResources().getDisplayMetrics().density));
        v.startAnimation(a);
    }
}

How to get text from TextView inside a CardView?


By : DANRA
Date : March 29 2020, 07:55 AM
may help you . Inside a CardView I have a LinearLayout with three TextViews in it and I want to get the text from these TextViews. My XML-file looks like this: , So many options in here.
1. Give id for your TextViews
code :
for (int i = 0; i < defense.getChildCount(); i++){
        CardView card = defense.getChildAt(i);
        ViewGroup viewGroup = ((ViewGroup)card.getChildAt(0));
        for(int j=0;j<viewGroup.getChildCount();j++){
            String getName = ((TextView)viewGroup.getChildAt(j)).getText().toString();
            id[i] = getName;
        }
    }

Holder cardview change textview color error


By : user3525946
Date : March 29 2020, 07:55 AM
seems to work fine i want to change color of my textview inside of cardview when its value is "kritis" or "kurang" but somehow everytime when my textview in position 0 and its value is either kritis or kurang it always change color textiew in position 0 and also position 7, and also when its in position 1 it will set color text view in position 8 too and so... and then i try to use logd to see howmany times my setcolor initiate and its only 1x (when changing color only position 1 and 7) or 2x (when changing color text position 0,1,7,8)(my cardview is inside recyclerview) , try adding else to set default background color :
code :
if(holder.textViewSKSkat.getText().equals("kritis") || holder.textViewSKSkat.getText().equals("kurang")){
    holder.textViewSKSkat.setTextColor(Color.rgb(255,0,0));
    Log.d("testing", "ayayaya");
} else {
    holder.textViewSKSkat.setTextColor(Color.rgb(0,0,0)); //TODO : SET DEFAULT COLOR
}


if(holder.textViewIPKkat.getText().equals("kritis") || holder.textViewIPKkat.getText().equals("kurang")){
    holder.textViewIPKkat.setTextColor(Color.rgb(255,0,0));
    Log.d("testing", "ayayaya");
} else {
    holder.textViewIPKkat.setTextColor(Color.rgb(0,0,0)); //TODO : SET DEFAULT COLOR
}
