Gridview v7-Unterstützung für ältere APIs android.support.v7.widget.Gridlayout konnte nicht installiert werden
Ich habe versucht, die v7-Unterstützungsbibliothek zu verwenden, um ein Rasterlayout in meinem Android-Projekt zu verwenden. Ich habe gesehen, dass viele Leute die gleichen Probleme hatten, die ich habe, aber all ihre Fehlerbehebungen funktionieren bei mir nicht. Ich habe Java aktualisiert. Ich habe die neueste Support-Bibliothek aktualisiert. Ich habe das Support Package zum Build-Pfad hinzugefügt. Ich habe versucht, eine Rasteransicht auf eine Ansicht zu ziehen und zuzulassen, dass Eclipse das Paket importiert. Nicht von dieser Arbeit. Ich bekomme weiterandroid.support.v7.widget.GridLayout konnte nicht instanziiert werden. Ich habe sogar ein Testprojekt erstellt und mit dem Support-Grid-Layout und dem gleichen Fehler begonnen. Hat jemand noch andere Ideen? Dies sind einige Orte, an denen ich nach Hilfe gesucht habe:
Eclipse mit dem Fehler android.support.v7.widget.GridLayout konnte nicht instanziiert werden
IntelliJ und android.support.v7.widget.GridLayout
unter vielen anderen....
Hier ist meine activity_main.xml:

Dies ist die genaue Ausnahme, die ich bekomme:
