效果图：

步骤：

//SettingActivity.java

button4.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            sensorDialog = new SensorDialog(SettingActivity.this); //调用Dialog
            sensorDialog.show();
        }
    });

//SensorDialog.java

public class SensorDialog extends Dialog {
    private SeekBar mSeekBar;
    private TextView mProgressText;

    protected SensorDialog(Context context) {
        super(context);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.setContentView(R.layout.sensorprogress);

        mSeekBar = (SeekBar) findViewById(R.id.seek);  //取得SeekBar对象
         mProgressText = (TextView) findViewById(R.id.progress);

        mSeekBar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
            @Override
            public void onStopTrackingTouch(SeekBar arg0) {
            }
            @Override
            public void onStartTrackingTouch(SeekBar arg0) {
            }
            @Override
            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                mProgressText.setText("当前值："+ Config.PROGRESS);
            }
        });
    }
}

//sensorprogress.xml

<?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">

    <SeekBar
        android:id="@+id/seek"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:max="100" android:progress="50"
        android:secondaryProgress="75" />

    <TextView android:id="@+id/progress"
           android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="当前值:50" android:textSize="30sp" />
</LinearLayout>
