本文提供了一个简单的 Android 应用示例，展示了如何使用不同类型的按钮组件，并通过 XML 布局文件进行界面设计。该应用包括普通按钮、小尺寸按钮及切换按钮等元素。

一. 简单实例

src

package cn.android.lyj;

import android.app.Activity;
import android.app.Dialog;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Spinner;
import android.widget.TextView;

public class Activity_01 extends Activity {

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

main.xml

<?xml version="1.0" encoding="utf-8"?>

<!-- Lots of buttons = need scrolling -->
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical">
        
        <!-- Regular sized buttons -->
        <Button android:id="@+id/button_normal"
            android:text="@string/buttons_1_normal"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />

        <!-- Small buttons -->
        <Button android:id="@+id/button_small"
            style="?android:attr/buttonStyleSmall"
            android:text="@string/buttons_1_small"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />

        <ToggleButton android:id="@+id/button_toggle"
            android:text="@string/buttons_1_toggle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
            
    </LinearLayout>
</ScrollView>

strings.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name= "app_name">Button</string>
    <string name="buttons_1_normal">Normal</string>
    <string name="buttons_1_right">Right</string>
    <string name="buttons_1_small">Small</string>
    <string name="buttons_1_small_right">S R</string>
    <string name="buttons_1_small_left">S L</string>
    <string name="buttons_1_small_up">S U</string>
    <string name="buttons_1_small_down">S D</string>
    <string name="buttons_1_toggle">Toggle</string>
</resources>

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="cn.android.lyj"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="10" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:label="@string/app_name"
            android:name=".Activity_01" >
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>
