Android PreferenceActivity Item Height

Question

I have a PreferenceActivity with two checkboxes. Everything is working correctly, but I have a UI problem; not all of the text for the checkbox fits onto the checkbox row.

Is there a nice way to set the minimum height for these checkbox preferences without hardcoding a value?

EDIT - adding xml:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen
xmlns:android="http://schemas.android.com/apk/res/android">
   <CheckBoxPreference
      android:key="alarm_set"
      android:title="@string/set_alarm_title"
      android:defaultValue="true" />
   <CheckBoxPreference
      android:key="store_pages"
      android:title="@string/store_downloaded_pages_title"
      android:summary="@string/store_downloaded_pages"
      android:defaultValue="false" />
</PreferenceScreen>

Based off this question about text preference having the same iussue I use this class.

public class LongSummaryCheckBoxPreference extends CheckBoxPreference 
{ 
    public LongSummaryCheckBoxPreference(Context ctx, AttributeSet attrs, int defStyle) 
    { 
        super(ctx, attrs, defStyle);         
    } 

    public LongSummaryCheckBoxPreference(Context ctx, AttributeSet attrs) 
    { 
        super(ctx, attrs);   
    } 

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

        TextView summary= (TextView)view.findViewById(android.R.id.summary); 
        summary.setMaxLines(4); 
    }        
} 

In the xml it then looks like this.

    <com.iforpowell.android.ipbike.LongSummaryCheckBoxPreference android:key="@string/key_distance_line_enable"
        android:title="@string/title_distance_line_enable" android:summary="@string/summary_distance_line_enable"
        android:defaultValue="true" />
    <com.iforpowell.android.ipbike.LongSummaryCheckBoxPreference android:key="@string/key_altitude_line_enable"
        android:title="@string/title_altitude_line_enable" android:summary="@string/summary_altitude_line_enable"
        android:defaultValue="true" />

I have exactly the same thing for EditTextPreference which has the same problem of a max of 2 lines for the summary in Api <= 7

In the xml you can set the height to "wrap_content". At that point it will size it to fit whatever you put in it. So, something along these lines:

<CheckBox
    android:id="@+id/checkBox1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="CheckBox" />

This should help

Just do it this way:

<!-- Application theme -->
<style name="AppTheme" parent="android:Theme.Holo.Light.DarkActionBar">
    <!-- Min item height -->
    <item name="android:listPreferredItemHeight">10dp</item>
</style>

another styling attributes that can be overridden can be found here preference item layout
