原文: [Android零基础入门第53节：拖动条SeekBar和星级评分条RatingBar][Android_53_SeekBar_RatingBar]

前面两期都在学习ProgressBar的使用，关于自定义ProgressBar的内容后期会继续学习的，本期先来学习ProgressBar的2个子组件SeekBar和RatingBar。

![0GF5cdwT0gy][]

# 一、SeekBar #

拖动条和进度条非常相似，只是进度条采用颜色填充来表明进度完成的程度，而拖动条则通过滑块的位置来标识数值——而且拖动条允许用户拖动滑块来改变值，因此拖动条通常用于对系统的某种数值进行调节，比如调节音量等。

由于拖动条SeekBar继承了 ProgressBar,因此ProgressBar所支持的XML属|性和方法完全适用于SeekBar。

SeekBar允许用户改变拖动条的滑块外观，改变滑块外观通过如下属性来指定。

*  android:thumb：指定一个Drawable对象，该对象将作为自定义滑块。

为了让程序能响应拖动条滑块位置的改变，程序可以为SeekBar绑定一个OnSeekBaiChangeListener监听器，其三个回调方法如下：

*  onProgressChanged：进度发生改变时会触发。
 *  onStartTrackingTouch：按住SeekBar时会触发。
 *  onStopTrackingTouch：放开SeekBar时触发。

接下来通过一个简单的示例程序来学习系统默认SeekBar的使用。

继续使用WidgetSample工程的advancedviewsample模块，在app/main/res/layout/目录下创建seekbar\_layout.xml文件，在其中填充如下代码片段：

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
                  android:layout_width="match_parent"
                  android:layout_height="match_parent"
                  android:orientation="vertical">
        <SeekBar
            android:id="@+id/seekBar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:max="100"
            android:progress="50" />
        <TextView
            android:id="@+id/prompt_tv"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
        <TextView
            android:id="@+id/pb_tv"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    </LinearLayout>

界面交互代码非常简单，为拖动条绑定一个监听器。新建SeekBarActivity.java文件，加载上面新建的布局文件，具体代码如下：

package com.jinyu.cqkxzsxy.android.advancedviewsample;
    
    import android.os.Bundle;
    import android.support.v7.app.AppCompatActivity;
    import android.widget.SeekBar;
    import android.widget.TextView;
    
    public class SeekBarActivity extends AppCompatActivity implements SeekBar.OnSeekBarChangeListener {
        private SeekBar mSeekBar = null;
        private TextView mPromptTv, mProgressTv;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.seekbar_layout);
    
            // 获取界面组件
            mSeekBar = (SeekBar) findViewById(R.id.seekBar);
            mPromptTv = (TextView) findViewById(R.id.prompt_tv);
            mProgressTv = (TextView) findViewById(R.id.pb_tv);
    
            // 注册事件监听器
            mSeekBar.setOnSeekBarChangeListener(this);
        }
    
        // 数值改变
        @Override
        public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
            mPromptTv.setText("正在拖动");
            mProgressTv.setText("当前数值:" + progress);
        }
    
        // 开始拖动
        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {
            mPromptTv.setText("开始拖动");
        }
    
        // 停止拖动
        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {
            mPromptTv.setText("停止拖动");
        }
    }

修改程序启动的Activity，运行程序，当拖动滑块时，可以可以看到下图所示界面效果。

![0GF5ci6IOsy][]

同ProgressBar一样，SeekBar也是同样的道理可以自定义出来很多不同种类的效果。

# 二、RatingBar #

星级评分条与拖动条有相同的父类：AbsSeekBar，因此它们十分相似。实际上星级评分条与拖动条的用法、功能都十分接近：它们都允许用户通过拖动来改变进度。RatingBar与SeekBar的最大区别在于：RatingBar通过星星来表示进度。

RatingBar所支持的常见XML属性如下：

*  android:isIndicator：是否用作指示，用户无法更改，默认false。
 *  android:numStars：显示多少个星星，必须为整数。
 *  android:rating：默认评分值，必须为浮点数。
 *  android:stepSize： 评分每次增加的值，必须为浮点数。

为了让程序能响应星级评分条评分的改变，可以考虑为它绑定一个OnRatingBarChangeListener监听器。

接下来通过一个简单的示例程序来学习系统默认RatingBar的使用。

继续使用WidgetSample工程的advancedviewsample模块，在app/main/res/layout/目录下创建ratingbar\_layout.xml文件，在其中填充如下代码片段：

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
                  android:layout_width="wrap_content"
                  android:layout_height="wrap_content"
                  android:orientation="vertical">
    
        <RatingBar
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:numStars="5"
            android:rating="3.5"
            android:stepSize="0.5" />
    </LinearLayout>

修改MainActivity.java里面加载的布局文件，运行后其效果如下图所示。

很多时候，默认的RatingBar并不能满足我们的要求，一般都是修改RatingBar的大小、图样、颜色等，也可以同ProgressBar一样自定义。
