Kamera in meiner App füllt nicht den Bildschirm

Question

Ich habe ein Problem mit meiner App, wo die Kamera nicht auf das Ende des Bildschirms auf der rechten Seite passt und hat einen riesigen schwarzen Balken. Bitte helfen Sie. Der Code für die Steuerung der Kamera ist nicht enthalten, da zu viel ausgegeben wird, um den Stack-Überlauf auszulösen. Die Größe der Kamera liegt hauptsächlich in den Layouts und der AutoFitTextureView.java. Bitte helfen Sie.

Versuchen Sie, es statt 500dp match_parent:

android:layout_width="match_parent" 
android:layout_height="match_parent"
