Bundle in Android with Example
It is known that Intents are used in Android to pass to the data from one activity to another. But there is one another way, that can be used to pass the data from one activity to another in a better way and less code space ie by using Bundles in Android. Android Bundles are generally used for passing data from one activity to another. Basically here concept of key-value pair is used where the data that one wants to pass is the value of the map, which can be later retrieved by using the key. Bundles are used with intent and values are sent and retrieved in the same fashion, as it is done in the case of Intent. It depends on the user what type of values the user wants to pass, but bundles can hold all types of values (int, String, boolean, char) and pass them to the new activity.
The following are the major types that are passed/retrieved to/from a Bundle:
putInt(String key, int value), getInt(String key, int value)
putString(String key, String value), getString(String key, String value)
putStringArray(String key, String[] value), getStringArray(String key, String[] value)
putChar(String key, char value), getChar(String key, char value)
putBoolean(String key, boolean value), getBoolean(String key, boolean value)
Using the Bundle in the Android App
The bundle is always used with Intent in Android. Now to use Bundle writes the below code in the MainActivity.
