这是我的 list ，抱歉我遗漏了:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.tchotchke.weatherpaper"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk

android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.tchotchke.weatherpaper.FullscreenActivity"
android:configChanges="orientation|keyboardHidden|screenSize"

android:name="com.tchotchke.weatherpaper.MyObjects"
android:label="@string/dummy_button">
<action android:name="android.intent.action.MYOBJECTS"/>
</activity>
</application>
</manifest>
我不太清楚 list 的工作原理，但从我所看到的来看，它似乎是合法的
最佳答案
它没有找到您的 Activity “com.tchotchke.MYOBJECTS，您需要在 list 中声明此 Activity 。如果这是您项目中的 Activity ，则通常通过以下方式完成 Intent :
Intent intent = new Intent(YourCurrentClassName.this, MYOBJECTS.class);
startActivity(intent);
希望这有帮助。
关于android - 当我单击按钮时，无论我如何实现 onClick，我的应用程序都会崩溃，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/15552629/
