Android ProgressDialog弹框的两种用法？

一、效果：

二、（进度条风格，风格为圆形，旋转的）和（进度条风格，风格为长形）

1.XML文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <Button
        android:id="@+id/Button01"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="圆形进度条" />
    <Button
        android:id="@+id/Button02"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="长形进度条" />
</LinearLayout>

2.在Activity中使用

package com.ruidde.pictureselectordemo;

import android.app.Activity;
import android.app.ProgressDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {
    private Context mContext;
    private Button Button1 = null;
    private Button Button2 = null;
    private int count = 0;
    //声明进度条对话框
    private ProgressDialog progressDialog = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mContext = this;
        initData();
    }

    private void initData() {
        Button1 = findViewById(R.id.Button01);
        Button2 = findViewById(R.id.Button02);

        Button1.setOnClickListener(new Button1Listener());
        Button2.setOnClickListener(new Button2Listener());
    }

    private class Button1Listener implements View.OnClickListener {

        public void onClick(View v) {
            //创建ProgressDialog对象
            progressDialog = new ProgressDialog(MainActivity.this);
            // 设置进度条风格，风格为圆形，旋转的
            progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
            // 设置ProgressDialog 标题
            progressDialog.setTitle("提示");
            // 设置ProgressDialog 提示信息
            progressDialog.setMessage("这是一个圆形进度条对话框");
            // 设置ProgressDialog 标题图标
            progressDialog.setIcon(R.mipmap.ic_launcher);
            // 设置ProgressDialog 的进度条是否不明确
            progressDialog.setIndeterminate(false);
            // 设置ProgressDialog 是否可以按退回按键取消
            progressDialog.setCancelable(true);
            //设置ProgressDialog 的一个Button
            progressDialog.setButton("确定", new SureButtonListener());
            // 让ProgressDialog显示
            progressDialog.show();
        }
    }

    //Dialog中确定按钮的监听器
    private class SureButtonListener implements android.content.DialogInterface.OnClickListener {

        public void onClick(DialogInterface dialog, int which) {
            //点击“确定按钮”取消对话框
            Toast.makeText(mContext ,"确定按钮" ,Toast.LENGTH_SHORT).show();
            dialog.cancel();
        }

    }

    private class Button2Listener implements View.OnClickListener {

        public void onClick(View v) {
            count = 0;
            // 创建ProgressDialog对象
            progressDialog = new ProgressDialog(MainActivity.this);
            // 设置进度条风格，风格为长形
            progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
            // 设置ProgressDialog 标题
            progressDialog.setTitle("提示");
            // 设置ProgressDialog 提示信息
            progressDialog.setMessage("这是一个长形对话框进度条");
            // 设置ProgressDialog 标题图标
            progressDialog.setIcon(R.mipmap.ic_launcher);
            // 设置ProgressDialog 进度条进度
            progressDialog.setProgress(100);
            // 设置ProgressDialog 的进度条是否不明确
            progressDialog.setIndeterminate(false);
            // 设置ProgressDialog 是否可以按退回按键取消
            progressDialog.setCancelable(true);
            // 让ProgressDialog显示
            progressDialog.show();
            new Thread() {
                public void run() {
                    try {
                        while (count <= 100) {
                            // 由线程来控制进度。
                            progressDialog.setProgress(count);
                            count = count + 2;
                            Thread.sleep(100);
                        }
                        progressDialog.cancel();
                    } catch (InterruptedException e) {
                        progressDialog.cancel();
                    }
                }
            }.start();
        }
    }

}
