第一次尝试短信。从一本 wrox 书中复制代码并且它有效，但是现在当我尝试插入输入自定义数字和自定义文本的功能时，我遇到了一个我无法弄清楚的错误（无效的目标地址......但我从一个模拟器到另一个与该示例一起工作的模拟器......当我输入数字时失败了）。以下是主要活动：
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.telephony.SmsManager;
public class SMSActivity extends Activity {
public String contactNumber;
public String messageText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
EditText contact_Number = (EditText)findViewById(R.id.contact_number);
contactNumber = contact_Number.getText().toString();
EditText text_Message = (EditText)findViewById(R.id.text_message);
messageText = text_Message.getText().toString();
}
public void onClick(View v) {
sendSMS(contactNumber, messageText);
}
private void sendSMS(String phoneNumber, String message) {
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phoneNumber, null, message, null, null);
}
}
这是 XML：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".SMSActivity" >
<EditText
android:id="@+id/contact_number"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true" >
<EditText
android:id="@+id/text_message"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="@+id/btnSendSMS" />
<Button
android:id="@+id/btnSendSMS"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="send"
android:onClick="onClick" />
</RelativeLayout>
</RelativeLayout>
如果您需要，这是我的清单：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="net.learn2develop.sms"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="14" />
<uses-permission
android:name="android.permission.SEND_SMS" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="net.learn2develop.sms.SMSActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
这是我点击发送之前的样子：
最后，logcat：
