  • setEntries

    public void setEntries(CharSequence[] entries)

    Sets the human-readable entries to be shown in the list. This will be shown in subsequent dialogs.

    Each entry must have a corresponding index in setEntryValues(CharSequence[]).

    Parameters:

    entries - The entries.

    See Also:

    setEntryValues(CharSequence[])

  • setEntries

    public void setEntries(int entriesResId)

    Parameters:

    entriesResId - The entries array as a resource.

    See Also:

    setEntries(CharSequence[])

  • getEntries

    public CharSequence[] getEntries()

    The list of entries to be shown in the list in subsequent dialogs.

    Returns:

    The list as an array.

  • setEntryValues

    public void setEntryValues(CharSequence[] entryValues)

    The array to find the value to save for a preference when an entry from entries is selected. If a user clicks on the second item in entries, the second item in this array will be saved to the preference.

    Parameters:

    entryValues - The array to be used as values to save for the preference.

  • setEntryValues

    public void setEntryValues(int entryValuesResId)

    Parameters:

    entryValuesResId - The entry values array as a resource.

    See Also:

    setEntryValues(CharSequence[])

  • getEntryValues

    public CharSequence[] getEntryValues()

    Returns the array of values to be saved for the preference.

    Returns:

    The array of values.

  • setValue

    public void setValue(String value)

    Sets the value of the key. This should be one of the entries in getEntryValues().

    Parameters:

    value - The value to set for the key.

  • getSummary

    public CharSequence getSummary()

    Returns the summary of this ListPreference. If the summary has a String formatting marker in it (i.e. "%s" or "%1$s"), then the current entry value will be substituted in its place.

    Overrides:

    getSummary in class Preference

    Returns:

    the summary with appropriate string substitution

    See Also:

    Preference.setSummary(CharSequence)

  • setSummary

    public void setSummary(CharSequence summary)

    Sets the summary for this Preference with a CharSequence. If the summary has a String formatting marker in it (i.e. "%s" or "%1$s"), then the current entry value will be substituted in its place when it's retrieved.

    Overrides:

    setSummary in class Preference

    Parameters:

    summary - The summary for the preference.

  • setValueIndex

    public void setValueIndex(int index)

    Sets the value to the given index from the entry values.

    Parameters:

    index - The index of the value to set.

  • getValue

    public String getValue()

    Returns the value of the key. This should be one of the entries in getEntryValues().

    Returns:

    The value of the key.

  • getEntry

    public CharSequence getEntry()

    Returns the entry corresponding to the current value.

    Returns:

    The entry corresponding to the current value, or null.

  • findIndexOfValue

    public int findIndexOfValue(String value)

    Returns the index of the given value (in the entry values array).

    Parameters:

    value - The value whose index should be returned.

    Returns:

    The index of the value, or -1 if not found.

  • onPrepareDialogBuilder

    protected void onPrepareDialogBuilder(AlertDialog.Builder builder)

    Description copied from class: DialogPreference
    Prepares the dialog builder to be shown when the preference is clicked. Use this to set custom properties on the dialog.

    Do not AlertDialog.Builder#create() or AlertDialog.Builder#show().

    Overrides:

    onPrepareDialogBuilder in class DialogPreference

  • onDialogClosed

    protected void onDialogClosed(boolean positiveResult)

    Description copied from class: DialogPreference
    Called when the dialog is dismissed and should be used to save data to the SharedPreferences.

    Overrides:

    onDialogClosed in class DialogPreference

    Parameters:

    positiveResult - Whether the positive button was clicked (true), or the negative button was clicked or the dialog was canceled (false).

  • onGetDefaultValue

    protected Object onGetDefaultValue(TypedArray a,
                           int index)

    Description copied from class: Preference
    Called when a Preference is being inflated and the default value attribute needs to be read. Since different Preference types have different value types, the subclass should get and return the default value which will be its value type.

    For example, if the value type is String, the body of the method would proxy to TypedArray.getString(int).

    Overrides:

    onGetDefaultValue in class Preference

    Parameters:

    a - The set of attributes.

    index - The index of the default value attribute.

    Returns:

    The default value of this preference type.

  • onSetInitialValue

    protected void onSetInitialValue(boolean restoreValue,
                         Object defaultValue)

    Description copied from class: Preference
    Implement this to set the initial value of the Preference.

    If restorePersistedValue is true, you should restore the Preference value from the SharedPreferences. If restorePersistedValue is false, you should set the Preference value to defaultValue that is given (and possibly store to SharedPreferences if Preference.shouldPersist() is true).

    This may not always be called. One example is if it should not persist but there is no default value given.

    Overrides:

    onSetInitialValue in class Preference

    Parameters:

    restoreValue - True to restore the persisted value; false to use the given defaultValue.

    defaultValue - The default value for this Preference. Only use this if restorePersistedValue is false.

  • onSaveInstanceState

    protected Parcelable onSaveInstanceState()

    Description copied from class: Preference
    Hook allowing a Preference to generate a representation of its internal state that can later be used to create a new instance with that same state. This state should only contain information that is not persistent or can be reconstructed later.

    Overrides:

    onSaveInstanceState in class DialogPreference

    Returns:

    A Parcelable object containing the current dynamic state of this Preference, or null if there is nothing interesting to save. The default implementation returns null.

    See Also:

    Preference.onRestoreInstanceState(android.os.Parcelable), Preference.saveHierarchyState(android.os.Bundle)

  • onRestoreInstanceState

    protected void onRestoreInstanceState(Parcelable state)

    Description copied from class: Preference
    Hook allowing a Preference to re-apply a representation of its internal state that had previously been generated by Preference.onSaveInstanceState(). This function will never be called with a null state.

    Overrides:

    onRestoreInstanceState in class DialogPreference

    Parameters:

    state - The saved state that had previously been returned by Preference.onSaveInstanceState().

    See Also:

    Preference.onSaveInstanceState(), Preference.restoreHierarchyState(android.os.Bundle)
