Android编程实现对话框形式进度条功能示例

package com.example.myapplication;
import android.app.ProgressDialog;
import android.content.DialogInterface;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
  ProgressDialog prodialog;
  Button show;
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    show = (Button) findViewById(R.id.show);
    show.setOnClickListener(this);
  }
  @Override
  public void onClick(View view) {
    prodialog = new ProgressDialog(MainActivity.this);
    prodialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
    prodialog.setTitle("");
    prodialog.setMessage("jb51");
    prodialog.setIcon(R.mipmap.ic_launcher);
    //设计进度条属性
    prodialog.setMax(100);
    prodialog.incrementProgressBy(50);
    //明确显示进度
    prodialog.setIndeterminate(false);
    prodialog.setButton(DialogInterface.BUTTON_POSITIVE,"确定",
    new DialogInterface.OnClickListener() {
      @Override
      public void onClick(DialogInterface dialogInterface, int i) {
        Toast.makeText(MainActivity.this,"hello",Toast.LENGTH_LONG).show();
      }
    });
    prodialog.setCancelable(true);
    prodialog.show();
  }
}
