name android:drawableStart

name android:drawableTop

name android:drawableBottom

Parameters
@NonNull TextView textView

The TextView against which to invoke the method.

@DrawableRes int start

Resource identifier of the start Drawable.

@DrawableRes int top

Resource identifier of the top Drawable.

@DrawableRes int end

Resource identifier of the end Drawable.

@DrawableRes int bottom

Resource identifier of the bottom Drawable.

setCustomSelectionActionModeCallback

Added in 1.1.0
Deprecated in 1.15.0-rc01
@ReplaceWith(expression = "textView.setCustomSelectionActionModeCallback(callback)")
public static void setCustomSelectionActionModeCallback(
    @NonNull TextView textView,
    @NonNull 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 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
@NonNull TextView textView

The TextView to set the action selection mode callback on.

@NonNull ActionMode.Callback callback

The action selection mode callback to set on textView.

setFirstBaselineToTopHeight

Added in 1.1.0
public static void setFirstBaselineToTopHeight(
    @NonNull TextView textView,
    @Px @IntRange(from = 0) 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.

name android:firstBaselineToTopHeight

Parameters
@NonNull TextView textView

TextView for which to set the padding.

@Px @IntRange(from = 0) int firstBaselineToTopHeight

distance between first baseline to top of the container in pixels

setLastBaselineToBottomHeight

Added in 1.1.0
public static void setLastBaselineToBottomHeight(
    @NonNull TextView textView,
    @Px @IntRange(from = 0) 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.

name android:lastBaselineToBottomHeight

Parameters
@NonNull TextView textView

TextView for which to set the padding.

@Px @IntRange(from = 0) int lastBaselineToBottomHeight

distance between last baseline to bottom of the container in pixels

Parameters
@NonNull TextView textView

the TextView to modify

ref android.R.styleable#TextView_lineHeight

Parameters

Added in 1.1.0
public static void setPrecomputedText(
