尝试发送电子邮件从偏好设置屏幕

Question

我创建的喜好XML与Android偏好活动，像这样：

<PreferenceCategory 
     android:title="@string/about"> 

    <PreferenceScreen 
      android:title="@string/customer_support" 
      android:summary="@string/email_description"> 
      <intent android:action="com.sample.android.turboweather.EMAIL_TARA" 
      /> 
    </PreferenceScreen> 

</PreferenceCategory> 

以下是我在我的清单中声明：

<activity android:name=".EmailTara" 
       android:launchMode="singleTop" 
       android:screenOrientation="portrait" 
       android:configChanges="keyboardHidden|orientation"> 
      <intent-filter> 
      <action android:name="com.sample.android.turboweather.EMAIL_TARA" /> 
      <category android:name="android.intent.category.DEFAULT"/> 

      </intent-filter> 
    </activity> 

这里是我的电子邮件活动：

public class EmailAccuwx extends SettingsActivity{ 
    private static final int EMAIL_SUCCESS = 0; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND); 
     emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Tara Android Flagship Application"); 
     emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{"[email protected]"}); 
     emailIntent.putExtra(Intent.EXTRA_TEXT, ""); 
     emailIntent.setType("message/rfc822"); 
     startActivity(Intent.createChooser(emailIntent, "Email Client Chooser"); 

     super.onCreate(savedInstanceState); 
    } 



}

我在logcat中得到这个错误：

06-07 09:43:52.570: ERROR/AndroidRuntime(1517): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.EMAIL_TARA [email protected] } 

任何帮助非常感谢！

你宣布你Activity清单文件为"EmailTara"，但您的活动类被称为"EmailAccuwx"。此外，您的Activity的意图筛选器列表"com.sample.android.turboweather.EmailTara"，但在您的偏好xml中，您为"android.intent.action.EMAIL_TARA"创建Intent。
