Android-ToggleButton和Switch

应用：ToggleButton和Switch在不同状态下，UI也不同

示例如下：

MainActivity.java

package com.example.widgetdemo;

import androidx.appcompat.app.AppCompatActivity;

import android.graphics.Color;
import android.os.Bundle;
import android.view.View;
import android.widget.Switch;
import android.widget.TextView;
import android.widget.ToggleButton;

public class MainActivity extends AppCompatActivity {

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



    }
    public void toggleText(View view){
        TextView tv = findViewById(R.id.textview);
        if (((ToggleButton)view).isChecked()){
            tv.setText("toggle button is on");
        }else {
            tv.setText("toggle button is off");
        }
    }
    public void switchText(View view){
        TextView tv = findViewById(R.id.textview);
        if (((Switch)view).isChecked()){
            tv.setText("toggle button is on");
        }else {
            tv.setText("toggle button is off");
        }
    }
}
