Intent intent=new Intent(MainActivity.this, ContactListActivity.class);
startActivity(intent);
MainActivity.this是用java编写的，ContactListActivity是用kotlin编写的。我试图调用 ContactListActivty 但最终收到错误
have you declared this activity in your AndroidManifest.xml?
我还在 list 文件中添加了该 Activity 。
<activity android:name="Chat_Activity$Connections$ContactListActivity"
android:parentActivityName=".MainActivity">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value=".MainActivity"/>
</activity>
编辑:
ContactListActivity.kt
class ContactListActivity : AppCompatActivity() {
private var mBroadcastReceiver: BroadcastReceiver? = null
private val TAG:String="ContactListActivity"
//static variable
object Obz{
@JvmStatic val GetContactListFromServer:String="Contact List"
}
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(layout.activity_contact_list)
title = "Contact list"
contact_list.hasFixedSize()
contact_list.layoutManager= LinearLayoutManager(this)
getContactListAndNextActivity()
}
fun getContactListAndNextActivity(){
contact_list.adapter= ContactListAdaptor(applicationContext, dbHelper(applicationContext).getContactList())
}
}
最佳答案
您的 list name条目看起来很可疑。
android:name="Chat_Activity$Connections$ContactListActivity"
我不确定完全限定的路径名是什么，但请尝试:
android:name=".ContactListActivity"
或
android:name="<qualified.path.to>.ContactListActivity"
