Method Detail

toggle

public void toggle()

Description copied from interface: Checkable

Change the checked state of the view to the inverse of its current state

Specified by:

toggle in interface Checkable

isChecked

public boolean isChecked()

Specified by:

isChecked in interface Checkable

Returns:

The current checked state of the view

setChecked

public void setChecked(boolean checked)

Changes the checked state of this text view.

Specified by:

setChecked in interface Checkable

Parameters:

checked - true to check the text, false to uncheck it

setCheckMarkDrawable

public void setCheckMarkDrawable(int resid)

Set the checkmark to a given Drawable, identified by its resourece id. This will be drawn when isChecked() is true.

Parameters:

resid - The Drawable to use for the checkmark.

setCheckMarkDrawable

public void setCheckMarkDrawable(Drawable d)

Set the checkmark to a given Drawable. This will be drawn when isChecked() is true.

Parameters:

d - The Drawable to use for the checkmark.

setPadding

public void setPadding(int left,
                       int top,
                       int right,
                       int bottom)

Description copied from class: View

Sets the padding. The view may add on the space required to display the scrollbars, depending on the style and visibility of the scrollbars. So the values returned from View.getPaddingLeft(), View.getPaddingTop(), View.getPaddingRight() and View.getPaddingBottom() may be different from the values set in this call.

Overrides:

setPadding in class TextView

Parameters:

left - the left padding in pixels

top - the top padding in pixels

right - the right padding in pixels

bottom - the bottom padding in pixels

onDraw

protected void onDraw(Canvas canvas)

Description copied from class: View

Implement this to do your drawing.

Overrides:

onDraw in class TextView

Parameters:

canvas - the canvas on which the background will be drawn

onCreateDrawableState

protected int[] onCreateDrawableState(int extraSpace)

Description copied from class: View

Generate the new Drawable state for this view. This is called by the view system when the cached Drawable state is determined to be invalid. To retrieve the current state, you should use View.getDrawableState().

Overrides:

onCreateDrawableState in class View

Parameters:

extraSpace - if non-zero, this is the number of extra entries you would like in the returned array in which you can place your own states.

Returns:

Returns an array holding the current Drawable state of the view.

See Also:

View.mergeDrawableStates(int[], int[])

drawableStateChanged

protected void drawableStateChanged()

Description copied from class: View

This function is called whenever the state of the view changes in such a way that it impacts the state of drawables being shown.

Be sure to call through to the superclass when overriding this function.

Overrides:

drawableStateChanged in class TextView

See Also:

Drawable.setState(int[])
