國際慣例先上圖

Step1

build.gradle增加

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

dependencies {
    ...
    compile 'com.github.Jay-Goo:RangeSeekBar:v1.1.0'
}

//minSdkVersion的值改為16及以上
minSdkVersion 16

Step2

xml增加

<LinearLayout
    xmlns:android
 
="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.xy.rangeseekbar.MainActivity"
    android:orientation="vertical"
 

    android:gravity="center"
    android:background="#e5e5e5"
    >

    <TextView
        android:id="@+id/progress2_tv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:background="@drawable/btn_dialog_box"
 

        />

    <com.jaygoo.widget.RangeSeekBar
        android:id="@+id/seekbar2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:lineColorSelected="@color/colorPrimary"
        app:lineColorEdge="@color/colorPrimaryDark"
        app:thumbSize="20dp"
        app:seekBarHeight="10dp"
        app:cellMode="number"
        app:seekBarMode="range"
        app:progressHintMode="alwaysHide"
        />

</LinearLayout>

MainActivity.java中程式碼

public class MainActivity extends AppCompatActivity {
    private RangeSeekBar seekbar2;
    private TextView tv2;
    private DecimalFormat df = new DecimalFormat("0");
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        seekbar2 = (RangeSeekBar)findViewById(R.id.seekbar2);
        tv2 = (TextView)findViewById(R.id.progress2_tv);
        //設定範圍
        seekbar2.setRange(0,179);
        //設定初始值
        seekbar2.setValue(50,100);

        seekbar2.setOnRangeChangedListener(new RangeSeekBar.OnRangeChangedListener() {
            @Override
            public void onRangeChanged(RangeSeekBar view, float min, float max, boolean isFromUser) {
                if (isFromUser) {
                    tv2.setText(df.format(min) + "-" + df.format(max));
                    seekbar2.setLeftProgressDescription(df.format(min));
                    seekbar2.setRightProgressDescription(df.format(max));
                }
            }
        });
    }
}

用於顯示選擇範圍的是一個TextView，考慮到它可能會被拉伸，所以背景用的是一張.9圖片，製作.9圖片教程請戳這裡
