at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:757)Ich verwende PinnedSectionListView, die ein benutzerdefiniertes Layout für Header als Kind auch hat. Das Problem, mit dem ich hier konfrontiert bin, ist, dass alle untergeordneten Layouts an den ersten Header angehängt werden, während der zweite Header nicht angezeigt wird. In meinem jsonarray habe ich 2 Überschriften und jeder hat einzelnes Kind. Ich habe versucht, den Code zu debuggen und festgestellt, dass die 'j' for-Schleife zweimal funktioniert, ohne auf die Schleife 'i' zu gehen. Aus diesem Grund werden beide untergeordneten Layouts an die erste Kopfzeile angehängt.

warum versuchen Sie es manuell zu analysieren? Sie haben GSON dafür !!! Sie arbeiten zu hart, ich denke, – matrix
Ich versuche, die Logik für Header und Child-Liste zu verstehen. Und das manuelle Parsen gibt mir eine gewisse Erklärung. Außerdem habe ich GSON nie benutzt, weil es Modellklasse benötigt. Könntest du mich wissen lassen, ob ich irgendwo falsch liege? – CodeAssasins
alles sieht gut aus .. versuchen Sie, die Länge von zwei Arrays zu überprüfen. – deejay
