无法弄清此SMSmanager错误

Question

尝试短信第一次。从wrox书复制的代码，它的工作，但现在当我尝试插入输入自定义数字和自定义文本的能力，我得到了一个错误，我无法弄清楚（目标地址无效......但我从1个仿真器到另一个与该示例一起工作的人......只是在输入数字时失败）。这里的主要活动：

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); 
    } 
} 

这里的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> 

这是我表现的情况下，你需要它：

<?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> 

下面是它看起来像之前我打派：

最后，logcat的：

感谢大家提前

Answer 1

答案就在我跳了出来。我将我的字符串命名为contactNumber和messageText，但是对phoneNumber和消息进行了调用。改变所有引用'contactNumber'和'messageText'修复它
