How to disable user interaction while ProgressBar is visible in android?

Question

I am using a custom ProgressBar. Now while a task is going on, I am showing the progress bar, but user can still interact with the views and controls. How do I disable the user interaction on whole view just like a ProgressDialog does , when it is visible.

Do I need to use a transparent view on top of main view and show the progress bar on that view and hide that view once a task is completed.

Or just get the id of my parentView and set it disabled ? But then I won't be able to dim the background, just like what happens when a dialog appears on the view/Activity/Fragment. Right?

I just want to know the way to disallow the user from any interaction while the progressbar is visible.

Thanks

Your question: How to disable the user interaction while ProgressBar is visible in android?

To disable the user interaction you just need to add the following code

getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE,                     WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE); 

To get user interaction back you just need to add the following code

getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE); 

Here is an example: Note:I am giving you just an example to show how to disable or retain user interaction

Add a progress bar in your xml.Something like this

<ProgressBar     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:id="@+id/progressBar"     android:visibility="gone"/> 

In MainActivity when a button pressed you show the progressbar and disable the user interaction.

@Override protected void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.activity_main);     mImageView = (ImageView) findViewById(R.id.imageView);     mProgressBar = (ProgressBar) findViewById(R.id.progressBar);     mImageView.setOnClickListener(new View.OnClickListener() {         @Override         public void onClick(View v) {             mProgressBar.setVisibility(View.VISIBLE);             getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE,                     WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE);         }     }); } 

And when user backPressed you remove the progressbar again retain the user interaction.Something like this

  @Override public void onBackPressed() {     super.onBackPressed();     mProgressBar.setVisibility(View.GONE);     getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE); } 

If you want to add a feature of disable and greyed out display, you need to add in your xml layout file a linear layout that fills the parent. Set its background to #B0000000 and its visibilty to GONE. Then programmatically set its visibility to VISIBLE.

Hope this help!
