一、运行效果：
二、MainActivity.java：

import androidx.appcompat.app.AppCompatActivity;
import android.app.ProgressDialog;
import android.content.DialogInterface;
import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {
private Button button,button2;
private ProgressDialog progressDialog,progressDialog1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = findViewById(R.id.button);
button2 = findViewById(R.id.button2);
button2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
progressDialog1 = new ProgressDialog(MainActivity.this);
progressDialog1.setProgressStyle(ProgressDialog.STYLE_SPINNER);
