Android实现多个按钮切换,关于Android多按钮切换的例子！

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：

MyAndroidApp

Turn On

Turn Off

Display

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

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:orientation="vertical" >

android:id="@+id/toggleButton1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="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" />

android:id="@+id/btnDisplay"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="@string/btn_display" />

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();

}

});

}

}
