根据特定条件启用和禁用视图

问：

我实现了一个下载按钮（ImageView），该按钮在单击时执行一些验证过程。如果所有验证都成功通过，则应用将导航到各自的活动。现在，我的要求是在单击下载按钮时禁用它，并且我想在链接验证期间的特定时间点再次启用它。

我需要在每个“if”或“else”条件中启用该按钮，其中不会发生导航到新意图。我在代码中添加了注释，以指示应在何处启用该按钮。

此外，在成功完成链接验证过程并且应用导航到新活动后，我还希望在用户从该活动返回时重新启用该按钮。

我尝试使用以下代码实现此功能，但它没有按预期工作：

private boolean isButtonEnabled = true;

//Btn is in OnCreate 
     downloadBtnCard.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

              
                if (isButtonEnabled) {
                    editTextValue[0] = Objects.requireNonNull(editText.getText()).toString();

                    // Step 1: Check if the network is available
                    if (isNetworkAvailable(getApplicationContext())) {
                        // Step 2: Check the network speed
                        try {
                            linkValidationAndUrl(editTextValue[0]);
                            downloadBtnCard.setClickable(false);
                            isButtonEnabled = false;
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                    } else {
                        // Show a message to the user indicating no network connection
