[Android] SwitchMaterial を設定する

２拓の切り替えのSwitch系が３種類、Switch, SwitchCompat, SwitchMaterial があります
簡単なON/OFFならどれもあまり変わりませんが、それなりに意味があることもあります

Android Studio
2021.2.1

SwitchMaterial

SwitchMaterialはSwitchCompatを継承しているのですが
Switchを継承してはいない
ただSwitchはCompoundButtonを継承しているのもあるので似た感じで使えます

java.lang.Object
↳	android.view.View
	↳	android.widget.TextView
		↳	android.widget.Button
			↳	android.widget.CompoundButton
				↳	androidx.appcompat.widget.SwitchCompat
					↳	com.google.android.material.switchmaterial.SwitchMaterial

基本設定

基本的な設定はSwitchCompatと同じように作成できます

MainActivity.java

//package com.example.testswithmaterial;

import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;

import com.google.android.material.switchmaterial.SwitchMaterial;

public class MainActivity extends AppCompatActivity {

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

        SwitchMaterial sw0 = findViewById(R.id.switch0);
        sw0.setOnCheckedChangeListener((buttonView, isChecked) -> {
            if (isChecked) {
                Log.v("debug","The SwitchMaterial is enabled");
            } else {
                Log.v("debug","The SwitchMaterial is disabled");
            }
        });
    }
}

//package com.example.testswithmaterial;

import androidx.appcompat.app.AppCompatActivity;

import android.util.Log;

import com.google.android.material.switchmaterial.SwitchMaterial;

public class MainActivity extends AppCompatActivity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

SwitchMaterial sw0 = findViewById(R.id.switch0);

sw0.setOnCheckedChangeListener((buttonView, isChecked) -> {

if (isChecked) {

Log.v("debug","The SwitchMaterial is enabled");

} else {

Log.v("debug","The SwitchMaterial is disabled");

}

});

}

色の変更

SwitchCompatとほぼ同じですが色合いに関しては微妙に異なります
それぞれのSwitchを比較してSwitchMaterialの色合いを変更してみます

MainActivity.java

//package com.example.testswitchmaterial;

import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import com.google.android.material.switchmaterial.SwitchMaterial;

public class MainActivity extends AppCompatActivity {

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

        SwitchMaterial sm = findViewById(R.id.switch_material);
        sm.setOnCheckedChangeListener((buttonView, isChecked) -> {
            if (isChecked) {
                sm.setText(R.string.enabled);
            } else {
                sm.setText(R.string.disabled);
            }
        });
    }
}

//package com.example.testswitchmaterial;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;

import com.google.android.material.switchmaterial.SwitchMaterial;

public class MainActivity extends AppCompatActivity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

SwitchMaterial sm = findViewById(R.id.switch_material);

sm.setOnCheckedChangeListener((buttonView, isChecked) -> {

if (isChecked) {

sm.setText(R.string.enabled);

} else {

sm.setText(R.string.disabled);

}

});

}

これで実行してみましょう

SwithとSwitchCompatに比べてSwitchMaterialのthumbの色が多少薄い感じがしますが
どうなんでしょう
