if this TV input can pause recording TV programs,
false
otherwise.

createSettingsIntent
public Intent createSettingsIntent ()

createSetupIntent
public Intent createSetupIntent ()
Returns an intent to start the setup activity for this TV input.
Returns | |
---|---|
Intent |
describeContents
public int describeContents ()
Describe the kinds of special objects contained in this Parcelable
instance's marshaled representation. For example, if the object will
include a file descriptor in the output of writeToParcel(android.os.Parcel, int)
,
the return value of this method must include the
CONTENTS_FILE_DESCRIPTOR
bit.
Returns | |
---|---|
int |
a bitmask indicating the set of special object types marshaled
by this Parcelable object instance.
Value is either 0 or CONTENTS_FILE_DESCRIPTOR |
equals
public boolean equals (Object o)
Indicates whether some other object is "equal to" this one.
The equals
method implements an equivalence relation
on non-null object references:
- It is reflexive: for any non-null reference value
x
,x.equals(x)
should returntrue
. - It is symmetric: for any non-null reference values
x
andy
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any non-null reference values
x
,y
, andz
, ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
. - It is consistent: for any non-null reference values
x
andy
, multiple invocations ofx.equals(y)
consistently returntrue
or consistently returnfalse
, provided no information used inequals
comparisons on the objects is modified. - For any non-null reference value
x
,x.equals(null)
should returnfalse
.
An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.
Parameters | |
---|---|
o |
Object : the reference object with which to compare. |
Returns | |
---|---|
boolean |
true if this object is the same as the obj
argument; false otherwise. |
getExtras
public Bundle getExtras ()
Returns domain-specific extras associated with this TV input.
Returns | |
---|---|
Bundle |
getId
public String getId ()
Returns a unique ID for this TV input. The ID is generated from the package and class name implementing the TV input service.
Returns | |
---|---|
String |
getParentId
public String getParentId ()
Returns the parent input ID.
A TV input may have a parent input if the TV input is actually a logical representation of a device behind the hardware port represented by the parent input. For example, a HDMI CEC logical device, connected to a HDMI port, appears as another TV input. In this case, the parent input of this logical device is the HDMI port.
Applications may group inputs by parent input ID to provide an easier access to inputs sharing the same physical port. In the example of HDMI CEC, logical HDMI CEC devices behind the same HDMI port have the same parent ID, which is the ID representing the port. Thus applications can group the hardware HDMI port and the logical HDMI CEC devices behind it together using this method.
Returns | |
---|---|
String |
the ID of the parent input, if exists. Returns null if the parent input is
not specified. |
getServiceInfo
public ServiceInfo getServiceInfo ()
Returns the information of the service that implements this TV input.
Returns | |
---|---|
ServiceInfo |
getTunerCount
public int getTunerCount ()
Returns the number of tuners this TV input has.
This method is valid only for inputs of type TYPE_TUNER
. For inputs of other
types, it returns 0.
Tuners correspond to physical/logical resources that allow reception of TV signal. Having N tuners means that the TV input is capable of receiving N different channels concurrently.
Returns | |
---|---|
int |
getType
public int getType ()
Returns the type of this TV input.
Returns | |
---|---|
int |
Value is TYPE_TUNER , TYPE_OTHER , TYPE_COMPOSITE , TYPE_SVIDEO , TYPE_SCART , TYPE_COMPONENT , TYPE_VGA , TYPE_DVI , TYPE_HDMI , or TYPE_DISPLAY_PORT |
hashCode
public int hashCode ()
Returns a hash code value for the object. This method is
supported for the benefit of hash tables such as those provided by
HashMap
.
The general contract of hashCode
is:
- Whenever it is invoked on the same object more than once during
an execution of a Java application, the
hashCode
method must consistently return the same integer, provided no information used inequals
comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. - If two objects are equal according to the
equals
method, then calling thehashCode
method on each of the two objects must produce the same integer result. - It is not required that if two objects are unequal
according to the
equals
method, then calling thehashCode
method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns | |
---|---|
int |
a hash code value for this object. |
isHidden
public boolean isHidden (Context context)
Checks if this TV input is marked hidden by the user in the settings.
Parameters | |
---|---|
context |
Context : Supplies a Context used to check if this TV input is hidden. |
Returns | |
---|---|
boolean |
true if the user marked this TV input hidden in settings. false
otherwise. |
isPassthroughInput
public boolean isPassthroughInput ()
Returns true
if this TV input is pass-though which does not have any real channels in
TvProvider. false
otherwise.
Returns | |
---|---|
boolean |
loadCustomLabel
public CharSequence loadCustomLabel (Context context)
Loads the custom label set by user in settings.
Parameters | |
---|---|

Context : Supplies a Context used to load the custom label. |
Returns | |
---|---|
CharSequence |
a CharSequence containing the TV input's custom label. null if there is no
custom label. |
loadIcon
public Drawable loadIcon (Context context)
Loads the user-displayed icon for this TV input.
Parameters | |
---|---|
context |
Context : Supplies a Context used to load the icon.
This value cannot be null . |
Returns | |
---|---|
Drawable |
a Drawable containing the TV input's icon. If the TV input does not have an icon,
application's icon is returned. If it's unavailable too, null is returned. |
loadLabel

Parameters | |
---|---|
context |
Context : Supplies a Context used to load the label.

a CharSequence containing the TV input's label. If the TV input does not have a label, its name is returned. |
toString
public String toString ()
Returns a string representation of the object.
Returns | |
---|---|
String |
a string representation of the object. |
