一、android的电话拨号器
1、项目结构：
效果图如下：
2、AndroidManifest.xml的配置文件
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="cn.huangjie.phone"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:label="@string/app_name"
android:name=".MainActivity" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<!-- android在一些个人隐私方面对做权限的申请，如果用户在安装软件的时候该软件
会涉及到拨号功能，那么在安装的时候android系统会提示用户会用到此功能，提示用
户要不要安装该软件,但是在开发环境中，是部署到模拟器上面的，是不会进行提示的 -->
<uses-permission android:name="android.permission.CALL_PHONE"/>
</manifest>
3、main.xml布局管理文件
<?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" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/phone" />
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/mobile" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/button"
android:id="@+id/button"/>
</LinearLayout>
4、strings.xml数值管理文件
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="hello">Hello World, MainActivity!</string>
<string name="app_name">电话拨号器</string>
<string name="phone">请输入手机号码</string>
<string name="button">拨号</string>
</resources>
5、R.java资源类文件
/* AUTO-GENERATED FILE. DO NOT MODIFY.
*
* This class was automatically generated by the
* aapt tool from the resource data it found. It
* should not be modified by hand.
*/
package cn.huangjie.phone;
public final class R {
public static final class attr {
}
public static final class drawable {
public static final int ic_launcher=0x7f020000;
}
public static final class id {
public static final int button=0x7f050001;
public static final int mobile=0x7f050000;
}
public static final class layout {
public static final int main=0x7f030000;
}
public static final class string {
public static final int app_name=0x7f040001;
public static final int button=0x7f040003;
public static final int hello=0x7f040000;
public static final int phone=0x7f040002;
}
}6、窗口和响应事件
package cn.huangjie.phone;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class MainActivity extends Activity {
private EditText mobileText;
/** Called when the activity is first created.
* onCreate方法在整个Active的声明周期内只会执行一次
* */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mobileText = (EditText) findViewById(R.id.mobile);
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new PhoneOnClickListener());
}
/**
* 定义成内部类的话，在软件加载进虚拟机的话会比把该类定义在外部要快点，
* 定义成内部类的话只要加载一个class文件即可，放在外部需要加载两个class文件
*/
private final class PhoneOnClickListener implements View.OnClickListener{
public void onClick(View v) {
String phone = mobileText.getText().toString();
Intent intent = new Intent();//意图
intent.setAction("android.intent.action.CALL");
intent.setData(Uri.parse("tel:" + phone));
// intent.addCategory("android.intent.category.DEFAULT");
startActivity(intent);//该方法内部会自动为intent添加类别意图,android.intent.category.DEFAULT
}
}
}
