问题
we already have a bunch of similar question to this but all of them was related to backward compatibility or they are on eclipse (as far i understand) but i think problem is occurring while inflating the cardView class it was working fine on my emulator (SDK 23) but when am trying it on my other emulator (SDK 19) am getting this error and the error is pointing me to this line :
@Override
public RecyclerView.ViewHolder onCreateViewHolderImpl(ViewGroup viewGroup, final ParallaxRecyclerAdapter<Information> adapter, int i) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService( Context.LAYOUT_INFLATER_SERVICE );
return new ViewHolder(inflater.inflate(R.layout.custom_row, viewGroup, false)); // this line
}
i also tried getActvity().inflate..... instead as above mentioned but still the same error exists , i also checked my gradle , everything seems fine here :
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'
compile 'com.mikhaellopez:circularimageview:2.1.1'
compile 'com.isseiaoki:simplecropview:1.0.16'
compile 'com.android.support:recyclerview-v7:23.4.0'
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:cardview-v7:23.4.0'
compile 'com.android.support:support-v4:23.4.0'
compile('com.github.afollestad.material-dialogs:core:0.8.5.3@aar') {
transitive = true
}
my error :

Try this it will help you remove this android:foreground="?android:attr/selectableItemBackground"
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:paddingLeft="4dp"
android:paddingRight="4dp"
android:paddingBottom="2dp">
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/cardview"
card_view:cardBackgroundColor="@android:color/white"
card_view:cardElevation="2dp"
card_view:cardMaxElevation="2dp"
card_view:cardUseCompatPadding="true">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
....here i have a bunch of other layout elements
</RelativeLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
