I am working on a commercial app as an internship. In one of its activity, I have tab view with two fragments. In each fragment, I'm using the card view to hold the views. The card view has one image view, two text views, and a button and in the bottom of the activity below the tab view, there is a button which has its visibility mode as "GONE".
Now What I want is, Whenever I click on the button in the card view, the button at the bottom of the activity should hide/show for respective clicks.
Cardcaptionadapter.java
public CaptionedImagesAdapterMenu.ViewHolder onCreateViewHolder(
ViewGroup parent, int viewType){
CardView cv = (CardView) LayoutInflater.from(parent.getContext())
.inflate(R.layout.card_captioned_image_menu, parent, false);
return new ViewHolder(cv);
}
@Override
public void onBindViewHolder(ViewHolder holder, final int position){
CardView cardView = holder.cardView;
ImageView imageView = (ImageView)cardView.findViewById(R.id.info_image);
Drawable drawable = ContextCompat.getDrawable(cardView.getContext(), imageIds[position]);
imageView.setImageDrawable(drawable);
imageView.setContentDescription(captions[position]);
TextView textView = (TextView)cardView.findViewById(R.id.info_text);
textView.setText(captions[position]);
TextView textView1 = cardView.findViewById(R.id.info_menu);
textView1.setText(desc[position]);
TextView textView2 = cardView.findViewById(R.id.info_price);
textView2.setText("₹ " + price[position]);
cardView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (listener != null) {
listener.onClick(position);
}
}
});
holder.button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if(holder.button.getText().equals("ADD")){
holder.button.setText("ADDED");
holder.button.setBackgroundColor(Color.parseColor("#00ff00"));
SharedPreferences sharedPref = context.getSharedPreferences("ADD",0);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putInt("ADDED", 1);
editor.apply();
}
else {
holder.button.setText("ADD");
holder.button.setBackgroundColor(Color.parseColor("#ffffff"));
SharedPreferences sharedPref = context.getSharedPreferences("ADD",0);
SharedPreferences.Editor editor = sharedPref.edit();
editor.clear();
editor.apply();
}
}
});
}
MenuActivity.java
SharedPreferences preferences = getSharedPreferences("ADD",0);
int addvalue = preferences.getInt("ADDED",0);
if(addvalue==1){
orderbutton.setVisibility(View.VISIBLE);
}
else{
orderbutton.setVisibility(View.GONE);
}
orderbutton.setOnClickListener(view -> {
orderbutton.setVisibility(View.GONE);
paybutton.setVisibility(View.VISIBLE);
});
