↳ | android.content.res.TypedArray |
Container for an array of values that were retrieved with
obtainStyledAttributes(AttributeSet, int[], int, int)
or obtainAttributes(AttributeSet, int[])
. Be
sure to call recycle()
when done with them.
The indices used to retrieve values from this structure correspond to
the positions of the attributes given to obtainStyledAttributes.

|
Retrieve the boolean value for the attribute at index.
index | Index of attribute to retrieve. |
---|---|
defValue | Value to return if the attribute is not defined. |
Retrieve the color value for the attribute at index. If
the attribute references a color resource holding a complex
ColorStateList
, then the default color from
the set is returned.
index | Index of attribute to retrieve. |
---|---|
defValue | Value to return if the attribute is not defined or not a resource. |
Retrieve the ColorStateList for the attribute at index.
The value may be either a single solid color or a reference to
a color or complex ColorStateList
description.
index | Index of attribute to retrieve. |
---|
Retrieve a dimensional unit attribute at index. Unit
conversions are based on the current DisplayMetrics
associated with the resources this TypedArray
object
came from.
index | Index of attribute to retrieve. |
---|---|
defValue | Value to return if the attribute is not defined or not a resource. |
Retrieve a dimensional unit attribute at index for use
as an offset in raw pixels. This is the same as
getDimension(int, float)
, except the returned value is converted to
integer pixels for you. An offset conversion involves simply
truncating the base value to an integer.
index | Index of attribute to retrieve. |
---|---|
defValue | Value to return if the attribute is not defined or not a resource. |
Retrieve a dimensional unit attribute at index for use
as a size in raw pixels. This is the same as
getDimension(int, float)
, except the returned value is converted to
integer pixels for use as a size. A size conversion involves
rounding the base value, and ensuring that a non-zero base value
is at least one pixel in size.
index | Index of attribute to retrieve. |
---|---|
defValue | Value to return if the attribute is not defined or not a resource. |
Retrieve the Drawable for the attribute at index. This
gets the resource ID of the selected attribute, and uses
Resources.getDrawable
of the owning
Resources object to retrieve its Drawable.
index | Index of attribute to retrieve. |
---|
Retrieve the float value for the attribute at index.
index | Index of attribute to retrieve. |
---|
Retrieve a fractional unit attribute at index.
index | Index of attribute to retrieve. |
---|---|
base | The base value of this fraction. In other words, a standard fraction is multiplied by this value. |
pbase | The parent base value of this fraction. In other words, a parent fraction (nn%p) is multiplied by this value. |
defValue | Value to return if the attribute is not defined or not a resource. |
Return an index in the array that has data.
at | The index you would like to returned, ranging from 0 to
getIndexCount() . |
---|
getValue(int, TypedValue)
and related APIs.
Return the number of indices in the array that actually have data.
Retrieve the integer value for the attribute at index.
index | Index of attribute to retrieve. |
---|---|
defValue | Value to return if the attribute is not defined. |
Retrieve the integer value for the attribute at index.
index | Index of attribute to retrieve. |
---|---|
defValue | Value to return if the attribute is not defined or not a resource. |
Special version of getDimensionPixelSize(int, int)
for retrieving
ViewGroup
's layout_width and layout_height
attributes. This is only here for performance reasons; applications
should use getDimensionPixelSize(int, int)
.
index | Index of the attribute to retrieve. |
---|---|
name | Textual name of attribute for error reporting. |
Special version of getDimensionPixelSize(int, int)
for retrieving
ViewGroup
's layout_width and layout_height
attributes. This is only here for performance reasons; applications
should use getDimensionPixelSize(int, int)
.
index | Index of the attribute to retrieve. |
---|---|
defValue | The default value to return if this attribute is not default or contains the wrong type of data. |
Retrieve the string value for the attribute at index, but only if that string comes from an immediate value in an XML file. That is, this does not allow references to string resources, string attributes, or conversions from other types. As such, this method will only return strings for TypedArray objects that come from attributes in an XML file.
index | Index of attribute to retrieve. |
---|
Returns a message about the parser state suitable for printing error messages.
Retrieve the resource identifier for the attribute at
index. Note that attribute resource as resolved when
the overall TypedArray
object is retrieved. As a
result, this function will return the resource identifier of the
final resource value that was found, not necessarily the
original resource that was specified by the attribute.
index | Index of attribute to retrieve. |
---|---|
defValue | Value to return if the attribute is not defined or not a resource. |
Return the Resources object this array was loaded from.
Retrieve the string value for the attribute at index.
index | Index of attribute to retrieve. |
---|
Retrieve the styled string value for the attribute at index.
index | Index of attribute to retrieve. |
---|
Retrieve the CharSequence[] for the attribute at index.
This gets the resource ID of the selected attribute, and uses
Resources.getTextArray
of the owning
Resources object to retrieve its String[].
index | Index of attribute to retrieve. |
---|
Returns the type of attribute at the specified index.
index | Index of attribute whose type to retrieve. |
---|
Retrieve the raw TypedValue for the attribute at index.
index | Index of attribute to retrieve. |
---|---|
outValue | TypedValue object in which to place the attribute's data. |
Determines whether there is an attribute at index.
index | Index of attribute to retrieve. |
---|
Retrieve the raw TypedValue for the attribute at index
and return a temporary object holding its data. This object is only
valid until the next call on to TypedArray
.
index | Index of attribute to retrieve. |
---|
Recycle the TypedArray, to be re-used by a later caller. After calling this function you must not ever touch the typed array again.
Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:
getClass().getName() + '@' + Integer.toHexString(hashCode())

toString
method
if you intend implementing your own toString
method.
