Question

我想要两件事：

隐藏我的＆＃34;播放＆＃34;点击它后按钮。

在我隐藏PLAY按钮之前，将其他按钮保留在相同的位置

    private int resourceId;
    private List<Object> objArrayList;
    public SparseBooleanArray mCheckedState;


    public AddProductsAdapter(Context context, int resource, List<Object> objList ) {
        super(context, resource,objList);
        this.context = context;
        this.resourceId = resource;
        mCheckedState = new SparseBooleanArray(objList.size());
        this.objArrayList = objList;
}

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View productview = convertView;
        ProductHolder productHolder;
        if (productview == null) {
            LayoutInflater inflater = (LayoutInflater) context
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            productview = inflater.inflate(resourceId, parent, false);
            productHolder = new ProductHolder();
            productHolder.productNameView = (TextView) productview.findViewById(R.id.nameProductView);
            productHolder.productIdView = (TextView) productview.findViewById(R.id.IdProductView);
            productHolder.productPriceView = (TextView) productview.findViewById(R.id.priceProductView);
            productHolder.checkBox = (CheckBox) productview.findViewById(R.id.checkBoxView);
            productview.setTag(productHolder);
            productview.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    ProductHolder productHolder = (ProductHolder) v.getTag();
                    if (productHolder.checkBox.isChecked()){
                        productHolder.checkBox.setChecked(false);
                    }
                    else{
                        productHolder.checkBox.setChecked(true);
                    }

                }
            });

}
        else{
            productHolder = (ProductHolder) productview.getTag();

        }
        try {

            if(objArrayList!=null){
            ProductEntity productEntity= (ProductEntity) objArrayList.get(position);
            String productName = productEntity.getName();

            String productId = productEntity.getProductId();
            String productPriceStandrd = productEntity.getStandard();

            productHolder.productNameView.setText(productName);
            productHolder.productIdView.setText(productId);
            productHolder.productPriceView.setText(productPriceStandrd);
            //productHolder.checkBox.setTag(position);
            productHolder.checkBox.setTag(position);
            productHolder.checkBox.setChecked(mCheckedState.get(position, false));
            productHolder.checkBox.setOnCheckedChangeListener(this);

            }
        }
         catch (Exception e) {
                e.printStackTrace();
            }

        return productview;
    }

    public boolean isChecked(int position) {
        return mCheckedState.get(position, false);
    }

    public void setChecked(int position, boolean isChecked) {
        mCheckedState.put(position, isChecked);

    }

    public void toggle(int position) {
        setChecked(position, !isChecked(position));

    }


    @Override
    public int getCount() {
        return objArrayList != null ? objArrayList.size() : 0;
    }

    private class ProductHolder {
        TextView productNameView;
        TextView productIdView;
        TextView productPriceView;
        CheckBox checkBox;

    }

    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        mCheckedState.put((Integer) buttonView.getTag(), isChecked);
    }

Answer 1

将动作侦听器添加到 PLAY 按钮b1。

b1.addActionListener(new ActionListener() {
  public void actionPerformed(ActionEvent e) {
     b1.setVisible(false); 
  } 
}

它应该为你隐藏。

单击后隐藏JButton
