Answer 1

Make custom progress dialog like below:

custom_progress_dialog.xml

<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:gravity="center"
  android:background="@null"
>
  <TextView
    android:id="@+id/animation"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/string"
    android:size="30dp"  />
</LinearLayout>

MyCustomProgressDialog.java

public class MyCustomProgressDialog extends ProgressDialog {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.custom_progress_dialog);

      ...
    }
    public static MyCustomProgressDialog ctor(Context context) {
        MyCustomProgressDialog dialog = new MyCustomProgressDialog(context);
        dialog.setIndeterminate(true);
        dialog.setCancelable(false);
        return dialog;
    }


     @Override
     public void show() {
        super.show();
    }

    @Override
    public void dismiss() {
      super.dismiss();
     }


}

and then use progress dialog class in asynctask like below:

class DemoAsyncTask extends AsyncTask<Void, Void, Void> {
  private final MyCustomProgressDialog progressDialog;

  public DemoAsyncTask(Context ctx) {
    progressDialog = MyCustomProgressDialog.ctor(ctx);
  }

  @Override
  protected void onPreExecute() {
    super.onPreExecute();
    textView.setVisibility(View.INVISIBLE);

    progressDialog.show();
  }

private ProgressDialog Dialog = new ProgressDialog(currentfile.this);

Dialog.setMessage(Html.fromHtml("<font color='white'  ><big>"
                    + "Downloading ..." + "</big></font>"));

Dialog.show();

Change the ProgressDialog Message font size in android programmatically:

String s= "Hello";
String title="MyTitle";

SpannableString ss1=  new SpannableString(title);
ss1.setSpan(new RelativeSizeSpan(2f), 0, ss1.length(), 0);  
ss1.setSpan(new ForegroundColorSpan(Color.RED), 0, ss1.length(), 0); 
SpannableString ss2=  new SpannableString(s);
ss2.setSpan(new RelativeSizeSpan(2f), 0, ss2.length(), 0);  
ss2.setSpan(new ForegroundColorSpan(Color.GREEN), 0, ss2.length(), 0); 

ProgressDialog pd = new ProgressDialog(this);
pd.setTitle(ss1);
pd.setMessage(ss2);
pd.show();
