我有下面的代码:
public class Fragment1 扩展 Fragment 实现 View.OnClickListener { 按钮按钮; @Override public View onCreateView(LayoutInflower inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { if(容器 == 空 ) 返回空值; View view = (LinearLayout)inflater.inflate(R.layout.fragment1_layout, container, false); button = (Button) view.findViewById(R.id.button); button.setOnClickListener(this); 返回视图; } @Override public void onClick(View v) { if(v.getId() == R.id.button) { startActivity(new Intent(getActivity().getApplicationContext(), Fragment3.class)); } }}我
从Android开始,我什至在manifext中声明了一项活动.xml例如:
活动 Android:名称="Pachage...destiny_fragment"
连续显示
E/Android运行时:致命异常:main android.content.ActivityNotFoundException: 无法找到显式活动类 {eguias.delogic.com.br.eguiasmobile/eguias.delogic.com.br.eguiasmobile.Fragment3};您是否在 AndroidManifest .xml 中声明了此活动? at android.app.Instrumentation.checkStartActivityResult(Instrumentation.java:1541) at android.app.Instrumentation.execStartActivity(Instrumentation.java:1416) at android.app.Activity.startActivityForResult(Activity.java:3351) at android.app.Activity.startActivityForResult(Activity.java:3312) at android.support.v4.app.FragmentActivity.startActivityFromFragment(FragmentActivity.java:826) at android.support.v4.app.Fragment.startActivity(Fragment.java:896) at eguias.delogic.com.br.eguiasmobile.Fragment1.onClick(Fragment1.java:37) at android.view.View.performClick(View.java:4084) at android.view.View$PerformClick.run(View.java:16966) at android.os.Handler.handleCallback(Handler.java:615) at android.os.Handler.dispatchMessage(Handler.java:92) at android.os.Looper.loop(Looper.java:137) at android.app.ActivityThread.main(ActivityThread.java:4745) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:511) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:786) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:553) at dalvik.system.NativeStart.main(Native Method)
应用程序正常运行,但错误"android.content.ActivityNotFoundException"始终显示在logcat中。
谢谢。
您的Fragment3.class
应该扩展Activity
,这应该在 AndroidManifest.xml
中声明。
main
android.content.ActivityNotFoundException: Unable to find explicit activity class {com.shamsan.droplivelast1/com.shamsan.droplivelast1.Reqlist}; have you declared this activity in your AndroidManifest.xml?
