Hey everyone, The requirement was to make a custom notification since the android's default notification only allows for an image. So I went through on how to attach a custom UI for notification when expanded, the ready answer was to create a custom view and pass to the notification manager and allowed from API level 16. So I did one and here the my layout xml code - filename: notification_custom_view_new:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:background="@color/GhostWhite";> <RelativeLayout android:id="@+id/header" android:layout_width="match_parent" android:layout_height="65dp"> <ImageView android:id="@+id/big_icon" android:layout_width="40dp" android:layout_height="40dp" android:layout_centerVertical="true" android:layout_marginLeft="12dp" android:scaleType="fitCenter" /> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:layout_alignBottom="@+id/big_icon" android:layout_alignTop="@+id/big_icon" android:layout_toRightOf="@+id/big_icon" android:gravity="center_vertical" android:orientation="horizontal" android:paddingLeft="16dp" android:paddingRight="16dp" android:weightSum="2"> <LinearLayout android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1.6" android:orientation="vertical"> <TextView android:id="@+id/title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:ellipsize="end" android:maxLines="1" android:text="Title" android:textColor="@color/colorBlackDimText" android:textSize="16sp" android:textStyle="bold" /> <TextView android:id="@+id/message" android:layout_width="wrap_content" android:layout_height="wrap_content" android:ellipsize="end" android:maxLines="2" android:paddingTop="2dp" android:text="message" android:textColor="@color/colorBlackDimText" android:textSize="14sp" /> </LinearLayout> <LinearLayout android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="0.4" android:gravity="center"> <TextView android:id="@+id/time" android:layout_width="wrap_content" android:layout_height="wrap_content" android:ellipsize="end" android:maxLines="2" android:padding="8dp" android:text="24:59" android:textColor="@color/colorBlackDimText" android:textSize="12sp" /> </LinearLayout> </LinearLayout> </RelativeLayout> <View android:id="@+id/shadow" android:layout_width="match_parent" android:layout_height="5dp" android:layout_below="@+id/header" android:background="@drawable/shadow" /> <ImageView android:id="@+id/big_picture" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_below="@+id/header" android:src="@drawable/vector_icon_collections" android:minHeight="240dp" android:scaleType="fitCenter" /></RelativeLayout> The way I referenced it in code: private RemoteViews assignRemote(Bitmap bitmap, String title, String message ){ RemoteViews expandedView = new RemoteViews(Application.getInstance(). getPackageName(), R.layout.notification_custom_view_new); expandedView.setTextViewText(R.id.title, title); expandedView.setTextViewText(R.id.message, message); expandedView. setImageViewBitmap(R.id.big_picture, bitmap); expandedView.setImageViewResource(R.id.big_icon, R.mipmap.ic_launcher); expandedView.setTextViewText(R.id.time, getOnlyHrsMin()); return expandedView; } assigning customview to notification manager: if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) { notification.bigContentView = assignRemote(bitmap, title, message); } But this gave me error saying bad notification, I have identified over 15+ same question here on stackoverflow without a right answer.. Some suggest it to be a resource missing and hence the error. I am sure from my end none of the values are null nor resources missing errors are not there in my remote view that is passed. Any help will be appreciated and also I have tried for around a couple of days to track the error but nothing good seems to happen. Please help me! Screenshot attached for layout UI.. also find the NotificatioUtils and layout xml files attached for reference.
