Android remoteviews in notification

android, android-layout

Solution

I found out what was wrong. In my case i was trying to show a layout which was greater than the default notification layout and as the result it was compressing my layout to fit the size of default notification.

I changed the views like this:

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

    <ImageView
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:id="@+id/album_art" />

    <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:id="@+id/wrapper"
        android:descendantFocusability="blocksDescendants"
        android:layout_toRightOf="@+id/album_art">

        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="false"
            android:gravity="center_vertical"
            android:orientation="vertical"
            android:id="@+id/info"
            android:layout_marginTop="10dp"
            android:layout_marginLeft="10dp">

            <TextView
                android:id="@+id/title"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="title"
                android:textStyle="bold"
                />

            <TextView
                android:id="@+id/text"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="singer"
                />
        </LinearLayout>

        <LinearLayout
            android:orientation="horizontal"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:descendantFocusability="blocksDescendants"
            android:layout_alignParentBottom="false"
            android:layout_centerHorizontal="true"
            android:id="@+id/player"
            android:layout_below="@+id/divider_horizontal"
            android:layout_marginTop="10dp">

            <ImageView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:id="@+id/prev"
                android:layout_marginRight="20dp"
                android:src="@drawable/ic_fast_rewind"
                android:layout_gravity="center_vertical" />

            <LinearLayout
                android:orientation="horizontal"
                android:layout_width="1dp"
                android:layout_height="fill_parent"
                android:background="#82c7c7c7"></LinearLayout>

            <ImageView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:id="@+id/play"
                android:layout_marginRight="20dp"
                android:layout_marginLeft="20dp"
                android:layout_gravity="center_vertical"
                android:src="@drawable/ic_pause" />

            <LinearLayout
                android:orientation="horizontal"
                android:layout_width="1dp"
                android:layout_height="fill_parent"
                android:background="#82c7c7c7" />

            <ImageView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:id="@+id/next"
                android:layout_marginLeft="20dp"
                android:layout_gravity="center_vertical"
                android:src="@drawable/ic_fast_forward" />

        </LinearLayout>

        <LinearLayout
            android:orientation="horizontal"
            android:layout_width="fill_parent"
            android:layout_height="1dp"
            android:id="@+id/divider_horizontal"
            android:background="#82c7c7c7"
            android:layout_below="@+id/info"
            android:layout_marginTop="10dp"
            android:layout_marginLeft="10dp"
            android:layout_marginRight="10dp"></LinearLayout>

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/close"
            android:layout_alignParentTop="true"
            android:layout_alignParentRight="true"
            android:layout_marginTop="5dp"
            android:layout_marginRight="5dp"
            android:background="@drawable/ic_close" />

    </RelativeLayout>

</RelativeLayout>

And in the notification method i added the following lines which solved the problem:

RemoteViews rv = new RemoteViews(getPackageName(), R.layout.notification_player);


        builder = new NotificationCompat.Builder(getApplicationContext())
                .setContent(rv)
                .setTicker("IranGrammy playing")
                .setAutoCancel(true)
                .setSmallIcon(ir.farzamhabibi.moozik.R.drawable.ic_launcher);

        rv.setImageViewBitmap(R.id.album_art, aq.getCachedImage(item.getImage()));
        rv.setTextViewText(R.id.title, item.getTitle());
        rv.setTextViewText(R.id.text, item.getSinger());
        rv.setOnClickPendingIntent(R.id.close, delete);
        rv.setOnClickPendingIntent(R.id.play, playPI);
        rv.setOnClickPendingIntent(R.id.next, nextPI);
        rv.setOnClickPendingIntent(R.id.prev, prevPI);
        Notification notif = builder.build();
        notif.bigContentView = rv;
        startForeground(10, notif);

Problem

I am developing a music player application. The player is in a service. When a song starts to play i want to show a custom notification with remoteViews. What i designed for the layout is: but unfortunately the textviews are gone when the notification is built: the code for the layout is as follows: notification_player.xml ``` <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <ImageView android:layout_width="140dp" android:layout_height="140dp" android:id="@+id/album_art" /> <RelativeLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/wrapper" android:layout_toRightOf="@+id/album_art" android:layout_alignBottom="@+id/album_art"> <LinearLayout android:orientation="horizontal" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_centerHorizontal="true" android:id="@+id/player" android:layout_marginBottom="10dp"> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/prev" android:layout_marginRight="5dp" android:src="@drawable/ic_fast_rewind" android:layout_gravity="center_vertical" /> <LinearLayout android:orientation="horizontal" android:layout_width="1dp" android:layout_height="fill_parent" android:background="#82c7c7c7"></LinearLayout> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/play" android:layout_marginRight="5dp" android:layout_marginLeft="5dp" android:layout_gravity="center_vertical" android:background="@drawable/ic_play_arrow" /> <LinearLayout android:orientation="horizontal" android:layout_width="1dp" android:layout_height="fill_parent" android:background="#82c7c7c7" /> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/next" android:layout_marginLeft="5dp" android:layout_gravity="center_vertical" android:background="@drawable/ic_fast_forward" /> </LinearLayout> <LinearLayout android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="1dp" android:id="@+id/divider_horizontal" android:layout_above="@+id/player" android:background="#82c7c7c7" android:layout_marginBottom="10dp" android:layout_marginRight="10dp" android:layout_marginLeft="10dp"></LinearLayout> <LinearLayout android:orientation="vertical" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_above="@+id/divider_horizontal"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:textAppearance="?android:attr/textAppearanceMedium" android:id="@+id/title" android:layout_marginLeft="10dp" android:layout_marginTop="25dp" android:text="Title" style="@style/NotificationTitle"/> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:textAppearance="?android:attr/textAppearanceSmall" android:text="singer" android:id="@+id/singer" android:layout_marginLeft="10dp" android:layout_marginTop="5dp" style="@style/NotificationText"/> </LinearLayout> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/close" android:layout_alignParentTop="true" android:layout_alignParentRight="true" android:layout_marginTop="5dp" android:layout_marginRight="5dp" android:background="@drawable/ic_close" /> </RelativeLayout> </RelativeLayout> ``` Code in service that is showing the notification: ``` NotificationCompat.Builder builder; RemoteViews rv = new RemoteViews(getPackageName(),R.layout.notification_player); rv.setImageViewBitmap(R.id.album_art,aq.getCachedImage(item.getImage())); rv.setTextViewText(R.id.title, item.getTitle()); rv.setTextViewText(R.id.singer, item.getSinger()); rv.setOnClickPendingIntent(R.id.close, delete); builder = new NotificationCompat.Builder(getApplicationContext()) .setContent(rv) .setSmallIcon(ir.farzamhabibi.moozik.R.drawable.ic_launcher); startForeground(10, builder.build()); ``` Any idea what the problem is? EDIT: I tried setting the LinearLayout height to wrap content and removing the margins I even tried adding a textView in all the layouts even in the parent of all but it seems the notification is removing all the textviews.
