ダイアログのカスタマイズ
まずレイアウトをカスタマイズ(zdy.xml)

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    >

    <TextView
        android:textSize="30sp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="   "
        android:layout_gravity="center"
        />
    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher_foreground"
        android:layout_gravity="center"
        />
</LinearLayout>

カスタムレイアウトを参照するjavaコード

//      
    public void a4(View view) {
        //1.    
        View view1 = LayoutInflater.from(this).inflate(R.layout.zdy,null);
        //2.     
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        //3.    
        builder.setView(view1);
        //4.          
        AlertDialog dialog = builder.create();
        //5.  
        dialog.show();

進捗バーダイアログ

//

        //1.     
        final ProgressDialog dialog = new ProgressDialog(this);
        //    
        dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);//     
       // dialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);//      
        dialog.setMax(100);//   
        dialog.setProgress(0);//   
        dialog.setMessage("    ");
        dialog.show();
        //     
        final Timer timer = new Timer();
        timer.schedule(new TimerTask() {
            int n = 0;
            @Override
            public void run() {
                if (n == 100){
                    dialog.dismiss();//  
                    timer.cancel();
                }
                dialog.setProgress(n+=10);
            }
        },0,1000);
    }
