各式各样的进度条，这里不演示效果了，大家可以自己写写，动手操作操作，看看效果

MainActivty代码：

package com.example.sixth_progressbar_android;import android.app.Activity;import android.app.ProgressDialog;import android.content.DialogInterface;import android.os.Bundle;import android.view.View;import android.view.Window;import android.widget.Button;import android.widget.ProgressBar;import android.widget.TextView;import android.widget.Toast;public class MainActivity extends Activity implements View.OnClickListener{    private ProgressBar press;    private Button add;    private Button reduce;    private Button reset;    private Button show;    private ProgressDialog progressdialog;    private TextView text2;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        //启用窗口特征，显示带进度和不带进度的进度条        requestWindowFeature(Window.FEATURE_PROGRESS);        requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);        setContentView(R.layout.activity_main);        //带进度进度条    与   不带进度进度条        setProgressBarVisibility(true);        setProgressBarIndeterminateVisibility(true);        setProgress(5000);        intt();    }    private void intt() {        press = (ProgressBar)findViewById(R.id.horiz);        add = (Button) findViewById(R.id.add);        reduce = (Button)findViewById(R.id.reduce);        reset = (Button) findViewById(R.id.reset);        text2 = (TextView)findViewById(R.id.text1);        show = (Button)findViewById(R.id.show);        //获取第一进度        int first = press.getProgress();        //获得第二进度        int second = press.getSecondaryProgress();        //获取最大进度        int max = press.getMax();        text2.setText("第一进度："+(int)(first/(float)max*100) +"%  第二进度："+(int)(second/(float)max*100) +"%");        //设置监听器        add.setOnClickListener(this);        reset.setOnClickListener(this);        reduce.setOnClickListener(this);        show.setOnClickListener(this);    }    @Override    public void onClick(View view) {        switch(view.getId())        {            case R.id.add: {                //增加第一进度和第二进度10%                press.incrementProgressBy(10);                press.incrementSecondaryProgressBy(10);                break;            }            case R.id.reduce: {                //减少第一进度和第二进度10%                press.incrementProgressBy(-20);                press.incrementSecondaryProgressBy(-20);                break;            }            case R.id.reset: {                //重置                press.setProgress(50);                press.setSecondaryProgress(80);                break;            }                case R.id.show :             {                 /*                 *页面显示设置                  */                 //页面设置，，新建一个ProgressDialog                  progressdialog = new ProgressDialog(MainActivity.this);                 //设置显示风格                 progressdialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);                 //设置标题                 progressdialog.setTitle("模拟器");                 //设置文本框内容                 progressdialog.setMessage("欢迎进入");                 //设置图标                 progressdialog.setIcon(R.mipmap.ic_launcher);                 /*                 *关于progressdialog一些属性设置                  */                 //设定最大进度                 progressdialog.setMax(100);                 //初始化进度                 progressdialog.incrementProgressBy(50);                 //进度条是明确清晰可见                 progressdialog.setIndeterminate(false);                 /*                 *设置一个确定按钮                  */                 progressdialog.setButton(DialogInterface.BUTTON_POSITIVE, "确定", new DialogInterface.OnClickListener() {                     @Override                     public void onClick(DialogInterface dialogInterface, int i) {                         Toast.makeText(MainActivity.this,"退出窗口",Toast.LENGTH_SHORT).show();                     }                 });                 //是否可以通过返回按钮退出对话框                 progressdialog.setCancelable(true);                 //显示progressdialog                 progressdialog.show();                 break;             }        }        text2.setText("第一进度："+(int)(press.getProgress()/(float)press.getMax()*100)+"% " +                      " 第二进度："+(int)(press.getSecondaryProgress()/(float)press.getMax()*100)+"%");    }}
