Progressdialog Not Showing Up In Activity

I am trying to include a ProgressDialog in my application. But it is not showing up. Here's the code snippet where i use the ProgressDialog: public class abcActivity extends Activi

Solution 1:

I think your code is wrong in a sense that you do all in the UI thread. You have to put callsomefunction() into a background thread.

publicvoidrunSomething()
{
    showDialog(BACKGROUND_ID);
    Thread t = new Thread(new Runnable() 
    {                   
        publicvoidrun() 
        {
            //do something
            handler.post(finishThread);
        }
    });

    t.start();
    // The progress wheel will only show up once all code coming here has been executed
}

And as well

protected Dialog onCreateDialog(int id)
{
    if(progressDialog == null) progressDialog = newProgressDialog(this);
    return progressDialog;
}

@OverrideprotectedvoidonPrepareDialog(int id, Dialog dialog)
{
    if(id == BACKGROUND_ID) 
    {
        progressDialog.setIndeterminate(true);
        progressDialog.setCancelable(false);
        progressDialog.setMessage("running for long ...");
    }
}

RunnablefinishThread=newRunnable()
{       
    publicvoidrun() 
    {
//long runningif(progressDialog != null) progressDialog.dismiss();
    }
};

Solution 2:

i think issue is in your switch condition pls verify it.

here is another method to display dialog in android try this.

publicstaticfinalintDIALOG2_KEY=1;
publicstatic ProgressDialog dialog1;

showDialog(DIALOG2_KEY); // use it where you want to display dialog 

dialog1.cancel();  // use it to cancel the dialog@Overridepublic Dialog onCreateDialog(int id) {
        if (id == 1) {
            dialog1 = newProgressDialog(this);
            dialog1.setMessage("Please wait...");
            dialog1.setIndeterminate(true);
            dialog1.setCancelable(true);
        }
        return dialog1;
    }

Solution 3:

Ensure you have this code called by debugging or adding a log. The code seems right to me.

Also, if you want to perform some operations in background and show a progress dialog while the performing, please use AsyncTask with ProgressDialog bounded, like here.

Solution 4:

ProgressDialog is deprecated in Android O , Use ProgressBar now.
