Android学习笔记(三) 之模拟打电话

新建一个Android工程，基于Anrdoid2.2模拟器创建

然后完善string.xml文件

[html]
<?xml version="1.0" encoding="utf-8"?>
<resources>

 <string name="hello">Hello World, SharpPhoneActivity!</string>
 <string name="app_name">SharpPhone</string>
 <string name="mobile">请输入手机号</string>
 <string name="button">拨打此号</string>
</resources>

然后是完善界面修改main.xml
[html]
<?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/mobile" />
 <EditText
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:id="@+id/phoneno" />
 <Button
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:text="@string/button"
 android:id="@+id/button"
 />
</LinearLayout>

接着需要在Activity类处理信息
[java]
package com.sharpanroid.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 SharpPhoneActivity extends Activity {
 /** Called when the activity is first created. */
 @Override
 public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.main);
 Button bt=(Button)this.findViewById(R.id.button);
 bt.setOnClickListener(new View.OnClickListener() {

 @Override
 public void onClick(View v) {

 EditText phoneText=(EditText)findViewById(R.id.phoneno);
 /**
 * 获取手机号
 */
 String phoneno=phoneText.getText().toString();
 if(null!=phoneno&&!"".equals(phoneno.trim())){
 /**
 * 数据通过Uri包封装，创建一个拨号意图
 */
 Intent intent=new Intent(Intent.ACTION_CALL,Uri.parse("tel:"+phoneno));

 startActivity(intent);
 }
 }
 });

 }
}
由于调用了打电话的服务，需要在AndroidManifest.xml 文件中进行引用
[java]
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
 package="com.sharpanroid.phone"
 android:versionCode="1"
 android:versionName="1.0" >

 <uses-sdk android:minSdkVersion="8" />
 <uses-permission android:name="android.permission.CALL_PHONE"/>
 <application
 android:icon="@drawable/ic_launcher"
 android:label="@string/app_name" >
 <activity
 android:name=".SharpPhoneActivity"
 android:label="@string/app_name" >
 <intent-filter>
 <action android:name="android.intent.action.MAIN" />

 <category android:name="android.intent.category.LAUNCHER" />
 </intent-filter>
