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
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 {
@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 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:
[xhtml] view plaincopy
<?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，
ReceiverSMS.java 代码：
[java] view plaincopy
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：
[java] view plaincopy
<?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：
[java] view plaincopy
//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);
}
});
