Question

aber aus irgendeinem magischen Grund im immer diese:

Testcode:

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:orientation="vertical" android:layout_width="match_parent" 
    android:layout_height="match_parent" android:paddingTop="100dp"> 

    <ImageView 
     android:id="@+id/imageView" 
     android:layout_width="match_parent" 
     android:layout_height="100dp" 
     android:layout_alignParentLeft="true" 
     android:layout_alignParentStart="true" 
     android:layout_alignParentTop="true" 
     app:srcCompat="@drawable/ic_dislike" /> 

    <ImageButton 
     android:id="@+id/imageButton" 
     android:layout_width="match_parent" 
     android:layout_height="100dp" 
     android:layout_alignParentLeft="true" 
     android:layout_alignParentStart="true" 
     android:layout_below="@+id/imageView"

Aktivität an diesem Punkt an ist fast alles auf Kommentar, da ich dieses Ding Figur kippe, so bezweifle ich, dass es etwas damit

möglicherweise Konflikte zu tun hat?

Answer 1

Versuchen entfernen "+" in dieser Zeile Ihres Image in Ihrem Layout:

android:layout_below="@+id/imageView" 

Weil "+" verwenden sollte nur auf "Android: id" Parameter eine ID zuweisen eine Ansicht

Mit dieser zusätzlichen „+“ layout_below sollte die Positionierung der Knopf unterhalb des Bildes zu korrigieren, werden scheitern.

Eine andere Möglichkeit ist versuchen, alle zu ersetzen "App: srcCompat" von „android: src“. Da Sie keine Vektor Drawables mit

Answer 2

Stellen Sie sicher, dass Sie vectorDrawables.useSupportLibrary = true in Ihrer build.gradle Datei

android { 
    defaultConfig { 
    vectorDrawables.useSupportLibrary = true 
    } 
}
