问题描述
我有以下按钮：
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/btn_create_user"
android:id="@+id/btn_create_user"
android:onClick="onClickCreateUser"
android:layout_alignParentBottom="true"
android:background="@color/btn_create_user"
android:layout_alignLeft="@+id/btn_login"
android:layout_alignStart="@+id/btn_login"
android:layout_marginBottom="23dp"
android:layout_alignRight="@+id/btn_login"
android:layout_alignEnd="@+id/btn_login" />
用下面的onclick功能：
with the following onclick function:
public void onClickCreateUser(View v){
Intent i = new Intent("dk.anapp.notebox.activity_createUser");
startActivity(i);
}
当我preSS的按钮，我得到以下错误：
When i press the button i get the following error:

我搜索左右，但唯一的答案我能找到的人谁忘了申报清单中的类
I searched SO but the only answer i could find is for people who forgot to declare the class in the manifest
这是我的清单：
<?xml version="1.0" encoding="utf-8"?>
<uses-sdk
android:minSdkVersion="9"
android:targetSdkVersion="18" />
<uses-permission android:name="android.permission.INTERNET" />
<application
android:name="dk.anapp.notebox.Mediator"
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="dk.anapp.notebox.Login"
android:label="@string/title_activity_login" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="dk.anapp.notebox.SoloActivity"
android:label="@string/title_activity_solo" >
<intent-filter>
<action android:name="dk.anapp.notebox.SoloActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity
android:name="dk.anapp.notebox.SpashScreen"
android:configChanges="orientation|keyboardHidden|screenSize"
android:label="@string/title_activity_spash_screen"
android:theme="@style/FullscreenTheme" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="dk.anapp.notebox.SpashScreen"
android:label="@string/title_activity_spash_screen" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="dk.anapp.notebox.MyGroups"
android:label="@string/title_activity_my_groups" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="dk.anapp.notebox.activity_createUser"
android:label="@string/title_activity_activity_create_user" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
那么，什么我做错了？
推荐答案
在你的清单只是做
<activity android:name="dk.anapp.notebox.activity_createUser" />
您应该使用＆LT;意向滤光器＆gt; 属性只有一次，指定要在启动时运行该活动
You should use this <intent-filter> attribute only once, to specify which Activity to run at startup
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
此外，改变你的code到
Furthermore, change your code to
public void onClickCreateUser(View v){
Intent i = new Intent(this, Activity_createUser.class);
startActivity(i);
}
我认为您的活动类叫做 Activity_createUser.java ，如果这不是你应该改变上述新意图（在此情况下，Activity_createUser的.class）; ，以配合您的活动类的名称
I assumed your activity class is called Activity_createUser.java, if this is not the case you should change the above new Intent(this, Activity_createUser.class); to match with your activity class' name
