I want to group some self-define Style in PreferenceScreen, So I
insert another layer for this group.
Before the group inserted, everything is work fine and it looks like
"Settings" in Android.
What I did is move the self-define style Items from main view to my
group view, and this group view located in main view.
xmls as followng:
1. mainview.xml
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen
xmlns:android="http://schemas.android.com/apk/res/android";
android:title="@string/my_label"
android:key="parent"
>
<com.android.settings.MyGroupPreference
android:width="400dip">
</com.android.settings.MyGroupPreference>
</PreferenceScreen>
2. inserted mygroupview.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:id="@+android:id/preference_group"
android:background="@drawable/panel_bg_background"
android:gravity="center_vertical"
android:layout_width="fill_parent"
android:layout_height="100.0dip"
android:layout_margin="10.0dip"
android:paddingRight="?android:attr/scrollbarSize"
>
<!-- Item A -->
<com.android.mine.ItemPreferenceScreen
settings:icon="@drawable/ic_item_A"
android:title="@string/item_A_title">
<intent
android:action="android.intent.action.MAIN"
android:targetPackage="com.android.mine"
android:targetClass="com.android.mine.ItemA" />
</com.android.mine.IconPreferenceScreen>
<!-- Item B -->
<com.android.mine.ItemPreferenceScreen
settings:icon="@drawable/ic_Item_B"
android:title="@string/Item_B_title">
<intent
android:action="android.intent.action.MAIN"
android:targetPackage="com.android.mine"
android:targetClass="com.android.mine.ItemB" />
</com.android.mine.ItemPreferenceScreen >
</RelativeLayout >
3. item_perference_screen.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:id="@+android:id/widget_frame"
android:layout_width="match_parent"
android:layout_height="40dip"
android:minHeight="?android:attr/listPreferredItemHeight"
android:gravity="center_vertical"
>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="2dip"
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:textColor="@color/black"
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="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="6dip"
android:layout_marginRight="6dip"
android:layout_gravity="center" />
</LinearLayout>
java code:
1. main Class
public class MainViewActivityextends PreferenceActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.mainview);
getListView().setBackgroundResource(R.color.white);
PreferenceGroup parent = (PreferenceGroup)
findPreference(KEY_PARENT);
Utils.updatePreferenceToSpecificActivityOrRemove(this, parent,
KEY_SYNC_SETTINGS, 0);
}
};
2. inserted group Class
public class MyGroup extends Preference {
//private Drawable mIcon;
public MyGroup(Context context, AttributeSet attrs) {
super(context, attrs);
setLayoutResource(R.layout.mygroupview);
}
};
3. item class
public class ItemPreferenceScreen extends Preference {
private Drawable mIcon;
public ItemPreferenceScreen (Context context, AttributeSet attrs)
{
this(context, attrs, 0);
}
public ItemPreferenceScreen (Context context, AttributeSet attrs,
int defStyle) {
super(context, attrs, defStyle);
setLayoutResource(R.layout.item_perference_screen);
TypedArray a = context.obtainStyledAttributes(attrs,
R.styleable.IconPreferenceScreen, defStyle, 0);
mIcon = a.getDrawable(R.styleable.ItemPreferenceScreen_icon);
}
@Override
public void onBindView(View view) {
super.onBindView(view);
ImageView imageView = (ImageView)
view.findViewById(R.id.icon);
if (imageView != null && mIcon != null) {
imageView.setImageDrawable(mIcon);
}
}
}
After I insert this group view, it report run-time error
android.view.InflateException: Binary XML file line #13: Error
inflating class...
Anybody know what's the problem?
