↳ | android.content.ComponentName |
Class Overview
Identifier for a specific application component (Activity
,Service
,BroadcastReceiver
, orContentProvider
) that is available. Two pieces of information, encapsulated here, are required to identify a component: the package (a String) it exists in, and the class (a String) name inside of that package.

Fields
public static final Creator<ComponentName>CREATOR
Added in API level 1Public Constructors
public ComponentName(String pkg,String cls)
Added in API level 1Create a new component identifier.
Parameters
pkg | The name of the package that the component exists in. Can not be null. |
---|---|
cls | The name of the class inside of pkg that implements the component. Can not be null. |
public ComponentName(Context pkg,String cls)
Added in API level 1Create a new component identifier from a Context and class name.
Parameters
pkg | A Context for the package implementing the component, from which the actual package name will be retrieved. |
---|---|
cls | The name of the class inside of pkg that implements the component. |
public ComponentName(Context pkg,Class<?> cls)
Added in API level 1Create a new component identifier from a Context and Class object.
Parameters
pkg | A Context for the package implementing the component, from which the actual package name will be retrieved. |
---|---|
cls | The Class object of the desired component, from which the actual class name will be retrieved. |
public ComponentName(Parcel in)
Added in API level 1Instantiate a new ComponentName from the data in a Parcel that was previously written withwriteToParcel(Parcel, int)
. Note that you must not use this with data written bywriteToParcel(ComponentName, Parcel)
since it is not possible to handle a null ComponentObject here.
Parameters
in | The Parcel containing the previously written ComponentName, positioned at the location in the buffer where it was written. |
---|
Public Methods
public ComponentName clone ()
Added in API level 1Creates and returns a copy of this Object
. The default implementation returns a so-called "shallow" copy: It creates a new instance of the same class and then copies the field values (including object references) from this instance to the new instance. A "deep" copy, in contrast, would also recursively clone nested objects. A subclass that needs to implement this kind of cloning should callsuper.clone()
to create the new instance and then create deep copies of the nested, mutable objects.
Returns
- a copy of this object.
public int compareTo(ComponentName that)
Added in API level 4public int describeContents()
Added in API level 1Describe the kinds of special objects contained in this Parcelable's marshalled representation.
Returns
- a bitmask indicating the set of special object types marshalled by the Parcelable.
public boolean equals(Object obj)
Added in API level 1Compares this instance with the specified object and indicates if they are equal. In order to be equal,o
must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.
The default implementation returns true
only if this == o
. SeeWriting a correctequals
method if you intend implementing your ownequals
method.
The general contract for the equals
and hashCode()
methods is that ifequals
returnstrue
for any two objects, thenhashCode()
must return the same value for these objects. This means that subclasses ofObject
usually override either both methods or neither of them.
Parameters
obj | the object to compare this instance with. |
---|
Returns
true
if the specified object is equal to thisObject
;false
otherwise.
public String flattenToShortString ()
Added in API level 1The same as flattenToString()
, but abbreviates the class name if it is a suffix of the package. The result can still be used withunflattenFromString(String)
.
Returns
- Returns a new String holding the package and class names. This is represented as the package name, concatenated with a '/' and then the class name.
See Also
unflattenFromString(String)
public String flattenToString ()
Added in API level 1Return a String that unambiguously describes both the package and class names contained in the ComponentName. You can later recover the ComponentName from this string throughunflattenFromString(String)
.
Returns
- Returns a new String holding the package and class names. This is represented as the package name, concatenated with a '/' and then the class name.
See Also
unflattenFromString(String)
public String getClassName ()
Added in API level 1Return the class name of this component.
public String getPackageName ()
Added in API level 1Return the package name of this component.
public String getShortClassName ()
Added in API level 1Return the class name, either fully qualified or in a shortened form (with a leading '.') if it is a suffix of the package.
public int hashCode()
Added in API level 1Returns an integer hash code for this object. By contract, any two objects for whichequals(Object)
returnstrue
must return the same hash code value. This means that subclasses ofObject
usually override both methods or neither method.
Note that hash values must not change over time unless information used in equals comparisons also changes.
See Writing a correct hashCode
method if you intend implementing your ownhashCode
method.
Returns
- this object's hash code.
public static ComponentName readFromParcel (Parcel in)
Added in API level 1Read a ComponentName from a Parcel that was previously written with writeToParcel(ComponentName, Parcel)
, returning either a null or new object as appropriate.
Parameters
in | The Parcel from which to read the ComponentName |
---|
Returns
- Returns a new ComponentName matching the previously written object, or null if a null had been written.
See Also
writeToParcel(ComponentName, Parcel)
public String toShortString ()
Added in API level 1Return string representation of this class without the class's name as a prefix.
public String toString ()
Added in API level 1Returns 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())
See Writing a useful toString
method if you intend implementing your owntoString
method.
Returns
- a printable representation of this object.
public static ComponentName unflattenFromString (String str)
Added in API level 1Recover a ComponentName from a String that was previously created with flattenToString()
. It splits the string at the first '/', taking the part before as the package name and the part after as the class name. As a special convenience (to use, for example, when parsing component names on the command line), if the '/' is immediately followed by a '.' then the final class name will be the concatenation of the package name with the string following the '/'. Thus "com.foo/.Blah" becomes package="com.foo" class="com.foo.Blah".
Parameters
str | The String that was returned by flattenToString(). |
---|
Returns
- Returns a new ComponentName containing the package and class names that were encoded instr
See Also
flattenToString()
public void writeToParcel(Parcel out, int flags)
Added in API level 1Flatten this object in to a Parcel.
Parameters
out | The Parcel in which the object should be written. |
---|---|
flags | Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE . |
public static void writeToParcel(ComponentName c,Parcel out)
Added in API level 1Write a ComponentName to a Parcel, handling null pointers. Must be read with readFromParcel(Parcel)
.
Parameters
c | The ComponentName to be written. |
---|---|
out | The Parcel in which the ComponentName will be placed. |
