调用打电话和发短信、收短信接口、发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：
先编写主界面Activaty，创建类CallAndSms作为为默认启动页
[java] view plaincopy
1.package jtapp.callandsms;
2.
3.import java.util.List;
4.
5.import android.app.Activity;
6.import android.content.Intent;
7.import android.net.Uri;
8.import android.os.Bundle;
9.import android.telephony.SmsManager;
10. import android.view.View;
11. import android.view.View.OnClickListener;
12. import android.widget.Button;
13. import android.widget.Toast;
14.
15. public class CallAndSms extends Activity {
16./** Called when the activity is first created. */
17.@Override
18.public void onCreate(Bundle savedInstanceState) {
19.super.onCreate(savedInstanceState);
20.setContentView(R.layout.main);
21.
22.setComponent();
23.}
24.
25.private void setComponent() {
26.Button bt1 = (Button) findViewById(R.id.Button01);
27.bt1.setOnClickListener(new OnClickListener() {
28.@Override
29.public void onClick(View v) {
30.Intent intent = new Intent(
31.Intent.ACTION_CALL, Uri.parse("tel:10010"));
32.startActivity(intent);
33.}
34.});
35.Button bt2 = (Button) findViewById(R.id.Button02);
36.bt2.setOnClickListener(new OnClickListener() {
37.@Override
38.public void onClick(View v) {
39.String smsContent = "102";
40.// note: SMS must be divided before being sent
41.SmsManager sms = SmsManager.getDefault();
42.List<String> texts = sms.divideMessage(smsContent);
43.for (String text : texts) {
44.sms.sendTextMessage("10010", null, text, null, null);
45.}
46.// note: not checked success or failure yet
47.Toast.makeText(
48.CallAndSms.this,
49."短信已发送",
50.Toast.LENGTH_SHORT ).show();
51.}
52.});
53.
54.Button bt3 = (Button) findViewById(R.id.Button03);
55.bt3.setOnClickListener(new OnClickListener() {
56.@Override
57.public void onClick(View v) {
58.Intent intent = new Intent(
59.Intent.ACTION_DIAL, Uri.parse("tel:10010"));
60.startActivity(intent);
61.}
62.});
63.Button bt4 = (Button) findViewById(R.id.Button04);
64.bt4.setOnClickListener(new OnClickListener() {
65.@Override
66.public void onClick(View v) {
67.Uri uri = Uri.parse("smsto:10010");
68.Intent it = new Intent(Intent.ACTION_SENDTO, uri);
69.it.putExtra("sms_body", "102");
70.startActivity(it);
71.}
72.});
73.}
74. }
主界面ui定义 main.xml 代码:
[xhtml] view plaincopy
1.<?xml version="1.0" encoding="utf-8"?>
2.<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
3.android:orientation="vertical" android:layout_width="fill_parent"
4.android:layout_height="fill_parent" android:gravity="center">
5.<TextView android:layout_width="fill_parent"
6.android:layout_height="wrap_content" android:text="Direct Method:"
7.android:gravity="center" />
8.<Button android:text="拨打10010客服电话" android:id="@+id/Button01"
9.android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
10.<Button android:text="短信10010查余额" android:id="@+id/Button02"
11.android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
12.<TextView android:text="InDirect Method:" android:id="@+id/TextView01"
13.android:layout_width="wrap_content" android:layout_height="wrap_content" />
14.<Button android:text="拨打10010客服电话" android:id="@+id/Button03"
15.android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
16.<Button android:text="短信10010查余额" android:id="@+id/Button04"
17.android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
18. </LinearLayout>
用于监听短信到来的Broadcast消息的文件，
ReceiverSMS.java 代码：
[java] view plaincopy
1.package jtapp.callandsms;
2.
3.import android.content.BroadcastReceiver;
4.import android.content.Context;
5.import android.content.Intent;
6.import android.os.Bundle;
7.import android.telephony.SmsMessage;
8.import android.widget.Toast;
9.
10. public class ReceiverSMS extends BroadcastReceiver {
11.
12.@Override
13.public void onReceive(Context context, Intent intent) {
14.if (intent.getAction().equals(
15."android.provider.Telephony.SMS_RECEIVED")) {
16.StringBuilder sb = new StringBuilder();
17.Bundle bundle = intent.getExtras();
18.if (bundle != null) {
19.Object[] pdus = (Object[]) bundle.get("pdus");
20.SmsMessage[] msgs = new SmsMessage[pdus.length];
21.for (int i = 0; i < pdus.length; i++) {
22.msgs[i] = SmsMessage
23..createFromPdu((byte[]) pdus[i]);
24.}
25.for (SmsMessage s : msgs) {
26.sb.append("收到来自");
27.sb.append(s.getDisplayOriginatingAddress());
28.sb.append("的SMS, 内容:");
29.sb.append(s.getDisplayMessageBody());
30.}
31.Toast.makeText(
32.context,
33."收到了短消息: " + sb.toString(),
34.Toast.LENGTH_LONG).show();
35.}
36.
37.}
38.}
39. }
AndroidManifest.xml中权限、activity和receiver的设定：
[java] view plaincopy
1.<?xml version="1.0" encoding="utf-8"?>
2.<manifest xmlns:android="http://schemas.android.com/apk/res/android"
3.package="jtapp.callandsms" android:versionCode="1" android:versionName="1.0">
4.<application android:icon="@drawable/icon" android:label="@string/app_name"
5.android:debuggable="true">
6.<activity android:name=".CallAndSms" android:label="@string/app_name">
7.<intent-filter>
8.<action android:name="android.intent.action.MAIN" />
9.<category android:name="android.intent.category.LAUNCHER" />
10.</intent-filter>
11.</activity>
12.<receiver android:name=".ReceiverSMS" android:enabled="true">
13.<intent-filter>
14.<action android:name="android.provider.Telephony.SMS_RECEIVED" />
15.</intent-filter>
16.</receiver>
17.</application>
18.<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>
19.<uses-permission android:name="android.permission.SEND_SMS"></uses-permission>
20.<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
21. </manifest>
补充，发Email 代码片段：
[java] view plaincopy
1.//Email
2.Button bt5 = (Button) findViewById(R.id.Button05);
3.bt5.setOnClickListener(new OnClickListener() {
4.@Override
5.public void onClick(View v) {
6.// Setup the recipient in a String array
7.String[] mailto = { "noam@gmail.com" };
8.// Create a new Intent to send messages
9.Intent sendIntent = new Intent(Intent.ACTION_SEND);
10.// Write the body of theEmail
11.String emailBody = "You're password is: ";
12.// Add attributes to the intent
13.//sendIntent.setType("text/plain"); // use this line for testing
14.// in the emulator
15.sendIntent.setType("message/rfc822"); // use this line for testing
16.// on the real phone
17.sendIntent.putExtra(Intent.EXTRA_EMAIL, mailto);
18.sendIntent.putExtra(Intent.EXTRA_SUBJECT, "Your Password");
19.sendIntent.putExtra(Intent.EXTRA_TEXT, emailBody);
20.startActivity(sendIntent);
21.}
22. });
