嘿,这是我曾经遇到的最奇怪的问题, 我有2个项目,每个项目在具有不同包名称的不同项目中完全相同。
现在我正在尝试运行第二个项目并且我得到一个NullPointerException,当我按错误将它发送给代码行时,它会加载相同的活动但是在另一个项目中。
知道为什么会这样吗?
这是我的清单:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="shibby.koteret"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="8" />
<uses-permission android:name="android.permission.CAMERA"></uses-permission>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" >
<activity
android:name=".TenKoteretActivity"
android:label="@string/app_name"
android:configChanges="keyboardHidden|orientation"
>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:label="@string/chosen_image" android:name="selectedImageActivity"
android:configChanges="keyboardHidden|orientation"
android:screenOrientation="portrait"
/>
<activity android:name="com.google.ads.AdActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>
</application>
</manifest>
除了包名和主要活动名称之外,这两个项目完全相同。
这是logcat:

我不认为它是相关的,但是被问到这是相关的Java代码(setContentView上的错误):
setContentView(R.layout.chosen_image);
ImageView imageView = (ImageView)this.findViewById(R.id.chosenImage2);
imageView.setImageBitmap(bitmap);
我检查了什么:
这可能只是Eclipse错误吗?有人见过这样的问题吗?
我在想,因为错误发生在XML文件上,它是否与R有某种关系?
答案 0 :(得分:0)
嗯,对我有用的是我关闭了第一个项目,然后Eclipse将我发送到正确的NullPointerException。
仍然不知道为什么会发生这种情况,但这对我来说很有用。
