Custom preference broken in Honeycomb/ICS

Question

I'm using a custom preference that I use the title, summary, and an icon in. The pref is used to select an item (skin, app, etc.), then the it will summarize the current choice. Here's the preference working correctly (top) and my issue on Honeycomb/ICS:

Space is being made for the preference, but even the default title/summary aren't showing up, and the intent for item selection isn't firing off either. Here's the preference layout:

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+android:id/widget_frame"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:minHeight="?android:attr/listPreferredItemHeight"
    android:gravity="center_vertical"
    android:paddingRight="?android:attr/scrollbarSize">
    <RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="16dip"
        android:layout_marginRight="6dip"
        android:layout_marginTop="6dip"
        android:layout_marginBottom="6dip"
        android:layout_weight="1">
        <TextView
            android:id="@+android:id/title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:singleLine="true"
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:ellipsize="marquee"
            android:fadingEdge="horizontal" />
        <TextView
            android:id="@+android:id/summary"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@android:id/title"
            android:layout_alignLeft="@android:id/title"
            android:textAppearance="?android:attr/textAppearanceSmall"
            android:maxLines="2" />
   </RelativeLayout>
   <ImageView
       android:id="@+id/icon"
       android:layout_width="48dp"
       android:layout_height="48dp"
       android:layout_gravity="center" />
</LinearLayout> 

And the custom preference itself:

import android.content.Context;
import android.content.pm.PackageManager;
import android.content.pm.PackageManager.NameNotFoundException;
import android.graphics.drawable.Drawable;
import android.preference.Preference;
import android.util.AttributeSet;
import android.util.Log;
import android.view.View;
import android.widget.ImageView;

public class SelectedAppPreference extends Preference {
    private Drawable mIcon;

    public SelectedAppPreference(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        final PackageManager pm = context.getPackageManager();
        String packageName = context.getSharedPreferences("appPrefs", Context.MODE_PRIVATE).getString("selected_app_package", null);

        this.setLayoutResource(R.layout.icon_pref);
        try {
            this.mIcon = pm.getApplicationIcon(packageName);
        } catch (NameNotFoundException e) {
            e.printStackTrace();
        }
    }

    public SelectedAppPreference(Context context, AttributeSet attrs) {
        super(context, attrs);
        final PackageManager pm = context.getPackageManager();
        String packageName = context.getSharedPreferences("appPrefs", Context.MODE_PRIVATE).getString("selected_app_package", null);

        this.setLayoutResource(R.layout.icon_pref);
        try {
            this.mIcon = pm.getApplicationIcon(packageName);
        } catch (NameNotFoundException e) {
            e.printStackTrace();
        }
    }

    @Override
    protected void onBindView(final View view) {
        super.onBindView(view);

        final ImageView imageView = (ImageView)view.findViewById(R.id.icon);
        if ((imageView != null) && (this.mIcon != null)) {
            imageView.setImageDrawable(this.mIcon);
        }
    }

    public void setIcon(final Drawable icon) {
        if (((icon == null) && (this.mIcon != null)) || ((icon != null) && (!icon.equals(this.mIcon)))) {
            this.mIcon = icon;
            this.notifyChanged();
        }
    }

    public Drawable getIcon() {
        return this.mIcon;
    }
}

Nothing too exciting in the preference itself. I have a feeling that the issue is in the preference layout xml, but I'm not sure what exactly is not working correctly. I can confirm that the preference works fine on Android 2.1, 2.2, and 2.3 devices, and I've had issues on 3.2 and 4.0. Any suggestions?

Answer 1

I had similar problem with a third party custom preference and fixed it by making the widget frame visible. It was invisible by default in ICS. Dont' know how it maps to your custom preference.

// This line was in the original code.
LinearLayout widgetFrameView = ((LinearLayout) mView
                    .findViewById(android.R.id.widget_frame));
...
// This line fixed the visibility issue
widgetFrameView.setVisibility(View.VISIBLE);

Also had to realign the view to make it consistent with the rest of ICS controls.
