Custom prefix broken in Honeycomb / ICS

Question

I use the user preference that I use in the title, summary and icon. The prefix is ​​used to select an item (skin, application, etc.), after which it summarizes the current selection. Here preference works correctly (above) and my problem with Honeycomb / ICS:

Space is done for preference, but even the title / summary is not displayed by default, and the intent to select an item is also not turned off. Here's the location of preferences:

<?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 user preference:

 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 fascinating about preference. I have the feeling that the problem is in the xml preferences layout, but I'm not sure what exactly is working incorrectly. I can confirm that preference works fine on Android 2.1, 2.2, and 2.3 devices, and I had problems with 3.2 and 4.0. Any suggestions?

Answer 1

I had a similar problem with a third-party user preference and fixed it, creating the visibility of the widget frame. This was invisible by default in ICS. Dont "know how it fits your user preferences.

 // 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); 

It was also necessary to rebuild the view to fit the rest of the ICS controls.

Answer 2

The exclusive preference of the third party that I corrected is taken from this site

https://github.com/attenzione/android-ColorPickerPreference/tree/master/src/net/margaritov/preference/colorpicker

My code (in ColorPickerPreference.setPreviewColor ()) looks like

 widgetFrameView.setVisibility(View.VISIBLE); final boolean preApi14 = android.os.Build.VERSION.SDK_INT < 14; final int rightPaddingDip = preApi14 ? 8 : 5; widgetFrameView.setPadding( widgetFrameView.getPaddingLeft(), widgetFrameView.getPaddingTop(), (int)(mDensity * rightPaddingDip), widgetFrameView.getPaddingBottom() ); 

Where

 float mDensity = getContext().getResources().getDisplayMetrics().density; 

This is with minSdkVersion = 8 and without targetSdkVersion. If you set targetSdkVersion to 14 or more, you may need to change “5” to something else until the user preference item on the right is correctly aligned with the standard ones (for example, check boxes).
