How to stop the progress bar after getting response from the server

Question

I'm trying to stop the progress bar after getting response from server. Below is the xml code that I've used

activity.xml

  <ProgressBar
        android:layout_weight="1"
        android:id="@+id/progressBar"
        android:indeterminate="true"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:minHeight="40dp"
        android:minWidth="40dp"
        tools:ignore="MissingConstraints" />

activity.kt

 var progressBar =  findViewById(R.id.progressBar) as ProgressBar
 doAsync {
            try {
                    progressBar.setVisibility(View.VISIBLE);
                    appList = getAppList(requestBody, LAUNCHER_BASE_URL)
                    Log.d("App list =", appList.toString())
                    appInfoList = populateList()
                    progressBar.setVisibility(View.GONE);
            } catch (e: Exception) {
                progressBar.setVisibility(View.GONE);
                Log.e("Exception-launcher", e.toString())
            }

From the above code,progress bar is not stopping even after getting the response. Any help would be appreciated

I've tried that but the page becomes blank after the progress bar stops

Because your progress bar is gone while it throw some exception not that time when you get success response. — Piyush, Apr 03 '19 at 07:02
so you wanted to show the response to user after progressbar stop ? and Your display becomes blank after progress bar gone. It means you didn't attached your response to your design. — Ashish, Apr 03 '19 at 07:26

Add progressBar.setVisibility(View.INVISIBLE); in your try clause too, because in its current state, it will only remove the loading for when the API fails:

 var progressBar =  findViewById(R.id.progressBar) as ProgressBar
 doAsync {
            try {
                    progressBar.setVisibility(View.VISIBLE);
                    appList = getAppList(requestBody, LAUNCHER_BASE_URL)
                    Log.d("App list =", appList.toString())
                    appInfoList = populateList()
                progressBar.setVisibility(View.INVISIBLE);
            } catch (e: Exception) {
                progressBar.setVisibility(View.INVISIBLE);
                Log.e("Exception-launcher", e.toString())
            }

I'm not sure how layout is laid out, but try `View.INVISIBLE` and see if that changes anything. – Adib Faramarzi Apr 03 '19 at 07:17

doAsync {
    try {
        progressBar.visibility = View.VISIBLE
        appList = getAppList(requestBody, LAUNCHER_BASE_URL)
        Log.d("App list =", appList.toString())
        appInfoList = populateList()
    } catch (e: Exception) {
        progressBar.visibility = View.GONE
        Log.e("Exception-launcher", e.toString())

i guess the problem is in your xml – Muhammad Muzammil Sharif Apr 03 '19 at 07:14
there is no issue in xml too that you attached in above – Muhammad Muzammil Sharif Apr 03 '19 at 07:16

i guess its your view composition that creating issue, you should try `View.INVISIBLE` instead of `View.GONE` – Muhammad Muzammil Sharif Apr 03 '19 at 07:22

You are hiding the progressbar only if the code goes in Exception (catch block).

Move your code after the catch block, as follows:

    try {
         progressBar.setVisibility(View.VISIBLE);
         appList = getAppList(requestBody, LAUNCHER_BASE_URL)
         Log.d("App list =", appList.toString())
         appInfoList = populateList()
    } catch (e: Exception) {
         Log.e("Exception-launcher", e.toString())
    }
    progressBar.setVisibility(View.GONE);

Let me know if that helps

Not really clear how can you handle View inside doAsync Normally this should represents in this way

 val progressBar =  findViewById<ProgressBar>(R.id.progressBar)
 progressBar.visibility = View.VISIBLE
 doAsync {
      try {
         appList = getAppList(requestBody, LAUNCHER_BASE_URL)
         Log.d("App list =", appList.toString())
         appInfoList = populateList()              
      } catch (e: Exception) {
          e.printStackTrace()
      }

      uiThread {
         progressBar.visibility = View.GONE
      }
 }
