Fields

CREATOR

Added in API level 21
public static final Creator<TvInputInfo> CREATOR

Public methods

canPauseRecording

Added in API level 31
public boolean canPauseRecording ()

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

Returns
boolean

canRecord

Added in API level 24
public boolean canRecord ()

Returns true if this TV input can record TV programs, false otherwise.

Returns
boolean

createSettingsIntent

Added in API level 21
Deprecated in API level 26
public Intent createSettingsIntent ()

This method was deprecated in API level 26.
Use createSetupIntent() instead. Settings activity is deprecated. Use setup activity instead to provide settings.

Returns an intent to start the settings activity for this TV input.

Returns

createSetupIntent

Added in API level 21
public Intent createSetupIntent ()

Returns an intent to start the setup activity for this TV input.

Returns
Intent

describeContents

Added in API level 21
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

Added in API level 21
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 return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

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

Added in API level 24
public Bundle getExtras ()

Returns domain-specific extras associated with this TV input.

Returns
Bundle

getId

Added in API level 21
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

Added in API level 21
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

Added in API level 21
public ServiceInfo getServiceInfo ()

Returns the information of the service that implements this TV input.

Returns
ServiceInfo

getTunerCount

Added in API level 24
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

Added in API level 21
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

Added in API level 21
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 in equals 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 the hashCode 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 the hashCode 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

Added in API level 24
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

Added in API level 21
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

Added in API level 24
public CharSequence loadCustomLabel (Context context)

Loads the custom label set by user in settings.

Parameters
context 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

Added in API level 21
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

Added in API level 21
public CharSequence loadLabel (Context context)

Loads the user-displayed label for this TV input.

Parameters
context Context: Supplies a Context used to load the label. This value cannot be null.

Returns
CharSequence a CharSequence containing the TV input's label. If the TV input does not have a label, its name is returned.

toString

Added in API level 21
public String toString ()

Returns a string representation of the object.

String a string representation of the object.

writeToParcel

Added in API level 21
public void writeToParcel (Parcel dest, 
                int flags)

Used to package this object into a Parcel.

Parameters
dest Parcel: The Parcel to be written. This value cannot be null.
