SeekBar setMin require at least api 26 in Android?

Question

I want to use a SeekBar in my android app. My minsdk version is must be 23. The compiler said setMin of SeekBar needs at least API level 26. Do I need some special support library for a simple SeekBar setMin?

I use Android Studio 3.0.1 on Linux. My build.gradle is like this:

apply plugin: 'com.android.application'
android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.zamek.boyler"
        minSdkVersion 23
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    ...


dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}

my layout snippet:

<SeekBar
        android:id="@+id/sb_hysteresis"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingTop="15dp"/>

my Activity code snippets:

import android.widget.SeekBar;
...
 private SeekBar hysteresis;
...
this.hysteresis = findViewById(R.id.sb_hysteresis);
this.hysteresis.setMin(10); <--Compiler said:Call requires API level 26 (current min is 23): android.widget.AbsSeekBar#setMin

thx,

Answer 1

I agree with Zeeshan's response but my approach to it is a bit different, maybe it'll help someone trying to achieve this.

First define your min and max values.

private static int MAX_VALUE = 220;
private static int MIN_VALUE = 50;

Then setup the seekbar max like this. By doing so you will make your seekbar have only the amount of values of the interval you wish to define.

seekbar.setMax(MAX_VALUE - MIN_VALUE);

After that whenever you check for the seekbar's value you must first add the min value that we defined.

@Override
public void onProgressChanged(SeekBar seekBar, int value, boolean fromUser) {
    displayValue((value + MIN_VALUE) + "cm");
}

SeekBar setMin() method was added in API level 26.

If you want to limit your SeekBar minimum value then you have to implement it manually.

 seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            @Override
            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                int min = 5;
                if(progress < min) {
                    seekBar.setProgress(min);
                }

            }
