大家好，又见面了，我是全栈君。

1。自定义字符串
Open “res/values/strings.xml” file, add some custom string for toggle buttons.

res/values/strings.xml文件：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="app_name">MyAndroidApp</string>
    <string name="toggle_turn_on">Turn On</string>
    <string name="toggle_turn_off">Turn Off</string>
    <string name="btn_display">Display</string>
</resources>

2。切换按钮
Open “res/layout/ main.xml” file, add two “切换按钮” and a normal button, inside the 线性布局.

文件：res/layout/ main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <ToggleButton
        android:id="@+id/toggleButton1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="ToggleButton" />

    <ToggleButton
        android:id="@+id/toggleButton2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textOn="@string/toggle_turn_on"
        android:textOff="@string/toggle_turn_off"
        android:checked="true" />

    <Button
        android:id="@+id/btnDisplay"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/btn_display" />

</LinearLayout>

笔记
Review the “togglebutton2”, we did customized the togglebutton2’s display text on and off and made it checked by default.

三.代码代码
Inside activity “onCreate（）” method, attach a click listeners on a normal button, to display the current state of the toggle button.

文件：myandroidappactivity.java

package com.mkyong.android;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
import android.widget.ToggleButton;

public class MyAndroidAppActivity extends Activity {

  private ToggleButton toggleButton1, toggleButton2;
  private Button btnDisplay;

  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    addListenerOnButton();

  }

  public void addListenerOnButton() {

    toggleButton1 = (ToggleButton) findViewById(R.id.toggleButton1);
    toggleButton2 = (ToggleButton) findViewById(R.id.toggleButton2);
    btnDisplay = (Button) findViewById(R.id.btnDisplay);

    btnDisplay.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

           StringBuffer result = new StringBuffer();
           result.append("toggleButton1 : ").append(toggleButton1.getText());
           result.append("\ntoggleButton2 : ").append(toggleButton2.getText());

           Toast.makeText(MyAndroidAppActivity.this, result.toString(),
            Toast.LENGTH_SHORT).show();

        }

    });

  }
}
