Example usage for Java android.util SparseArray fields, constructors, methods, implement or subclass
The text is from its open source code.
| SparseArray() Creates a new SparseArray containing no mappings. | |
| SparseArray(int initialCapacity) Creates a new SparseArray containing no mappings that will not require any additional memory allocation to store the specified number of mappings. |
| void | append(int key, E value) Puts a key/value pair into the array, optimizing for the case where the key is greater than all existing keys in the array. |
| void | clear() Removes all key-value mappings from this SparseArray. |
| void | delete(int key) Removes the mapping from the specified key, if there was any. |
| E | get(int key) Gets the Object mapped from the specified key, or null if no such mapping has been made. |
| E | get(int key, E valueIfKeyNotFound) Gets the Object mapped from the specified key, or the specified Object if no such mapping has been made. |
| int | indexOfKey(int key) Returns the index for which #keyAt would return the specified key, or a negative number if the specified key is not mapped. |
| int | keyAt(int index) Given an index in the range 0...size()-1, returns the key from the indexth key-value mapping that this SparseArray stores. |
| void | put(int key, E value) Adds a mapping from the specified key to the specified value, replacing the previous mapping from the specified key if there was one. |
| void | remove(int key) Alias for #delete(int) . |
| void | setValueAt(int index, E value) Given an index in the range 0...size()-1, sets a new value for the indexth key-value mapping that this SparseArray stores. |
| int | size() Returns the number of key-value mappings that this SparseArray currently stores. |
| E | valueAt(int index) Given an index in the range 0...size()-1, returns the value from the indexth key-value mapping that this SparseArray stores. |
