Android开发之调用（Call, Dial, SMSManager, Broadcast, Email）

打电话和发短信可以说是最核心的应用了，本文就来阐述它的调用方法。可以分为直接调用--直接电话或短信发出，已经间接调用--进入拨号或短信撰写页面，等待用户确认内容后由用户发出.
先看代码效果截图：

<ignore_js_op>


先编写主界面Activaty，创建类CallAndSms作为为默认启动页

package jtapp.callandsms;

import java.util.List;

import android.app.Activity;

import android.content.Intent;

import android.net.Uri;

import android.os.Bundle;

import android.telephony.SmsManager;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.Toast;

public class CallAndSms extends Activity {

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

setComponent();

}

private void setComponent() {

Button bt1 = (Button) findViewById(R.id.Button01);

bt1.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

Intent intent = new Intent(

Intent.ACTION_CALL, Uri.parse("tel:10010"));

startActivity(intent);

}

});

Button bt2 = (Button) findViewById(R.id.Button02);

bt2.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

String smsContent = "102";

// note: SMS must be divided before being sent

SmsManager sms = SmsManager.getDefault();

List<String> texts = sms.divideMessage(smsContent);

for (String text : texts) {

sms.sendTextMessage("10010", null, text, null, null);

}

// note: not checked success or failure yet

Toast.makeText(

CallAndSms.this,

"短信已发送",

Toast.LENGTH_SHORT ).show();

}

});

Button bt3 = (Button) findViewById(R.id.Button03);

bt3.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

Intent intent = new Intent(

Intent.ACTION_DIAL, Uri.parse("tel:10010"));

startActivity(intent);

}

});

Button bt4 = (Button) findViewById(R.id.Button04);

bt4.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

Uri uri = Uri.parse("smsto:10010");

Intent it = new Intent(Intent.ACTION_SENDTO, uri);

it.putExtra("sms_body", "102");

startActivity(it);

}

});

}

}

主界面ui定义 main.xml 代码:

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

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical" android:layout_width="fill_parent"

android:layout_height="fill_parent" android:gravity="center">

<TextView android:layout_width="fill_parent"

android:layout_height="wrap_content" android:text="Direct Method:"

android:gravity="center" />

<Button android:text="拨打10010客服电话" android:id="@+id/Button01"

android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>

<Button android:text="短信10010查余额" android:id="@+id/Button02"

android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>

<TextView android:text="InDirect Method:" android:id="@+id/TextView01"

android:layout_width="wrap_content" android:layout_height="wrap_content" />

<Button android:text="拨打10010客服电话" android:id="@+id/Button03"

android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>

<Button android:text="短信10010查余额" android:id="@+id/Button04"

android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>

</LinearLayout>

用于监听短信到来的Broadcast消息的文件，

[align=left]ReceiverSMS.java 代码：[/align]

package jtapp.callandsms;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.os.Bundle;

import android.telephony.SmsMessage;

import android.widget.Toast;

public class ReceiverSMS extends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

if (intent.getAction().equals(

"android.provider.Telephony.SMS_RECEIVED")) {

StringBuilder sb = new StringBuilder();

Bundle bundle = intent.getExtras();

if (bundle != null) {

Object[] pdus = (Object[]) bundle.get("pdus");

SmsMessage[] msgs = new SmsMessage[pdus.length];

for (int i = 0; i < pdus.length; i++) {

msgs[i] = SmsMessage

.createFromPdu((byte[]) pdus[i]);

}

for (SmsMessage s : msgs) {

sb.append("收到来自");

sb.append(s.getDisplayOriginatingAddress());

sb.append("的SMS, 内容:");

sb.append(s.getDisplayMessageBody());

}

Toast.makeText(

context,

"收到了短消息: " + sb.toString(),

Toast.LENGTH_LONG).show();

}

}

}

}

AndroidManifest.xml中权限、activity和receiver的设定：

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

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="jtapp.callandsms" android:versionCode="1" android:versionName="1.0">

<application android:icon="@drawable/icon" android:label="@string/app_name"

android:debuggable="true">

<activity android:name=".CallAndSms" android:label="@string/app_name">

<intent-filter>

<action android:name="android.intent.action.MAIN" />

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

</intent-filter>

</activity>

<receiver android:name=".ReceiverSMS" android:enabled="true">

<intent-filter>

<action android:name="android.provider.Telephony.SMS_RECEIVED" />

</intent-filter>

</receiver>

</application>

<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>

<uses-permission android:name="android.permission.SEND_SMS"></uses-permission>

<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>

</manifest>

补充，发Email 代码片段：

//Email

Button bt5 = (Button) findViewById(R.id.Button05);

bt5.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

// Setup the recipient in a String array

String[] mailto = { "noam@gmail.com" };

// Create a new Intent to send messages

Intent sendIntent = new Intent(Intent.ACTION_SEND);

// Write the body of theEmail

String emailBody = "You're password is: ";

// Add attributes to the intent

//sendIntent.setType("text/plain"); // use this line for testing

// in the emulator

sendIntent.setType("message/rfc822"); // use this line for testing

// on the real phone

sendIntent.putExtra(Intent.EXTRA_EMAIL, mailto);

sendIntent.putExtra(Intent.EXTRA_SUBJECT, "Your Password");

sendIntent.putExtra(Intent.EXTRA_TEXT, emailBody);

startActivity(sendIntent);

}

});
