1。自定義字串

Open “res/values/strings.xml” file, add some custom string for toggle buttons.

res/values/strings.xml檔案：

<?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。切換按鈕

Open “res/layout/ main.xml” file, add two “切換按鈕” and a normal button, inside the 線性佈局.

檔案：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>

筆記

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

三.程式碼程式碼

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

檔案：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();

}

});

}
}
