  • onBindView

    protected void onBindView(View view)

    Description copied from class: Preference
    Binds the created View to the data for this Preference.

    This is a good place to grab references to custom Views in the layout and set properties on them.

    Make sure to call through to the superclass's implementation.

    Overrides:

    onBindView in class Preference

    Parameters:

    view - The View that shows this Preference.

    See Also:

    Preference.onCreateView(ViewGroup)

  • getSummary

    public CharSequence getSummary()

    Description copied from class: Preference
    Returns the summary of this Preference.

    Overrides:

    getSummary in class Preference

    Returns:

    The summary.

    See Also:

    Preference.setSummary(CharSequence)

  • 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.

  • 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.

  • onKey

    public boolean onKey(View v,
                int keyCode,
                KeyEvent event)

    Description copied from class: Preference
    Allows a Preference to intercept key events without having focus. For example, SeekBarPreference uses this to intercept +/- to adjust the progress.

    Overrides:

    onKey in class Preference

    Returns:

    True if the Preference handled the key. Returns false by default.

  • setMax

    public void setMax(int max)

  • setProgress

    public void setProgress(int progress)

  • getProgress

    public int getProgress()

  • onProgressChanged

    public void onProgressChanged(SeekBar seekBar,
                         int progress,
                         boolean fromUser)

    Description copied from interface: SeekBar.OnSeekBarChangeListener
    Notification that the progress level has changed. Clients can use the fromUser parameter to distinguish user-initiated changes from those that occurred programmatically.

    Specified by:

    onProgressChanged in interface SeekBar.OnSeekBarChangeListener

    Parameters:

    seekBar - The SeekBar whose progress has changed

    progress - The current progress level. This will be in the range 0..max where max was set by ProgressBar.setMax(int). (The default value for max is 100.)

    fromUser - True if the progress change was initiated by the user.

  • onStartTrackingTouch

    public void onStartTrackingTouch(SeekBar seekBar)

    Description copied from interface: SeekBar.OnSeekBarChangeListener
    Notification that the user has started a touch gesture. Clients may want to use this to disable advancing the seekbar.

    Specified by:

    onStartTrackingTouch in interface SeekBar.OnSeekBarChangeListener

    Parameters:

    seekBar - The SeekBar in which the touch gesture began

  • onStopTrackingTouch

    public void onStopTrackingTouch(SeekBar seekBar)

    Description copied from interface: SeekBar.OnSeekBarChangeListener
    Notification that the user has finished a touch gesture. Clients may want to use this to re-enable advancing the seekbar.

    Specified by:

    onStopTrackingTouch in interface SeekBar.OnSeekBarChangeListener

    Parameters:

    seekBar - The SeekBar in which the touch gesture began

  • 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 Preference

    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 Preference

    Parameters:

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

    See Also:

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