                Drawable bottom)

Sets the Drawables (if any) to appear to the start of, above, to the end of, and below the text. Use null if you do not want a Drawable there. The Drawables must already have had Drawable.setBounds(Rect) called.

Calling this method will overwrite any Drawables previously set using TextView.setCompoundDrawables(Drawable, Drawable, Drawable, Drawable) or related methods.

Parameters
`textView`	`TextView`: The TextView against which to invoke the method.
`start`	`Drawable`
`top`	`Drawable`
`end`	`Drawable`
`bottom`	`Drawable`

public static void setCompoundDrawablesRelativeWithIntrinsicBounds (TextView textView, 
                int start, 
                int top, 
                int end, 
                int bottom)

Sets the Drawables (if any) to appear to the start of, above, to the end of, and below the text. Use 0 if you do not want a Drawable there. The Drawables' bounds will be set to their intrinsic bounds.

Calling this method will overwrite any Drawables previously set using TextView.setCompoundDrawables(Drawable, Drawable, Drawable, Drawable) or related methods.

Parameters
`textView`	`TextView`: The TextView against which to invoke the method.
`start`	`int`: Resource identifier of the start Drawable.
`top`	`int`: Resource identifier of the top Drawable.
`end`	`int`: Resource identifier of the end Drawable.
`bottom`	`int`: Resource identifier of the bottom Drawable.

public static void setCompoundDrawablesRelativeWithIntrinsicBounds (TextView textView, 
                Drawable start, 
                Drawable top, 
                Drawable end, 
                Drawable bottom)

Sets the Drawables (if any) to appear to the start of, above, to the end of, and below the text. Use null if you do not want a Drawable there. The Drawables' bounds will be set to their intrinsic bounds.

Calling this method will overwrite any Drawables previously set using TextView.setCompoundDrawables(Drawable, Drawable, Drawable, Drawable) or related methods.

Parameters
`textView`	`TextView`: The TextView against which to invoke the method.
`start`	`Drawable`
`top`	`Drawable`
`end`	`Drawable`
`bottom`	`Drawable`

public static void setCustomSelectionActionModeCallback (TextView textView, 
                ActionMode.Callback callback)

Sets a selection action mode callback on a TextView. Also this method can be used to fix a bug in framework SDK 26/27. On these affected devices, the bug causes the menu containing the options for handling ACTION_PROCESS_TEXT after text selection to miss a number of items. This method can be used to fix this wrong behaviour for a text view, by passing any custom callback implementation. If no custom callback is desired, a no-op implementation should be provided. Note that, by default, the bug will only be fixed when the default floating toolbar menu implementation is used. If a custom implementation of Menu is provided, this should provide the method Menu#removeItemAt(int) which removes a menu item by its position, as given by Menu#getItem(int). Also, the following post condition should hold: a call to removeItemAt(i), should not modify the results of getItem(j) for any j < i. Intuitively, removing an element from the menu should behave as removing an element from a list. Note that this method does not exist in the Menu interface. However, it is required, and going to be called by reflection, in order to display the correct process text items in the menu.

Parameters
`textView`	`TextView`: The TextView to set the action selection mode callback on.
`callback`	`ActionMode.Callback`: The action selection mode callback to set on textView.

public static void setFirstBaselineToTopHeight (TextView textView, 
                int firstBaselineToTopHeight)

Updates the top padding of the TextView so that firstBaselineToTopHeight is equal to the distance between the first text baseline and the top of this TextView. Note that if FontMetrics.top or FontMetrics.ascent was already greater than firstBaselineToTopHeight, the top padding is not updated.

Parameters
`textView`	`TextView`
`firstBaselineToTopHeight`	`int`: distance between first baseline to top of the container in pixels

See also:

public static void setLastBaselineToBottomHeight (TextView textView, 
                int lastBaselineToBottomHeight)

Updates the bottom padding of the TextView so that lastBaselineToBottomHeight is equal to the distance between the last text baseline and the bottom of this TextView. Note that if FontMetrics.bottom or FontMetrics.descent was already greater than lastBaselineToBottomHeight, the bottom padding is not updated.

Parameters
`textView`	`TextView`
`lastBaselineToBottomHeight`	`int`: distance between last baseline to bottom of the container in pixels

See also:

public static void setLineHeight (TextView textView, 
                int lineHeight)

Sets an explicit line height for this TextView. This is equivalent to the vertical distance between subsequent baselines in the TextView.

Parameters
`textView`	`TextView`
`lineHeight`	`int`: the line height in pixels

See also:

public static void setPrecomputedText (TextView textView,
