I've a problem with my project. When the user push a button, I generate a new images gallery (not with Gallery class because is deprecated) with a Fragment. When i go to another part of the application, when the user push this button again muy app generate a new images gallery to the right to the previous gallery.
When this button is pressed 3 or 4 times, the app crack because requiere a lot of memory.
My ask is: How can I delete the previous gallery (Fragment) when i press the button the 2 or 3 or 4... time?
I try to do with onPause (call super.onDestroy(), this.onDetach(), ((Object) layoutDinamicoHorizontal).destroyItem() ... on onPause).
My Fragment has a two LinearLayout, one vertical (vertical), and one horizontal(layoutDinamicoHorizontal) and the code is in onActivityCreated:
XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/layoutContenedor"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top|center_horizontal"
android:gravity="top|center_horizontal"
android:orientation="vertical">
<HorizontalScrollView
android:id="@+id/ScrollHorizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="none">
<LinearLayout
android:id="@+id/linearLayoutHorizontal"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
</LinearLayout>
</HorizontalScrollView>
</LinearLayout>
