For example, to use the latest version of the framework, you can add the following dependencies: implementation 'com.android.support:core-utils:1.0.0' In the code, the import statement can be used to introduce the classes that need to be used, such as: import android.support.v4.util.ArrayMap; import android.support.v4.text.TextUtilsCompat; import android.support.v4.util.Pair; Then, you can use the various functions provided by the framework. The following are sample codes for some commonly used functions: 1. Use ArrayMap for key value pairing operations: ArrayMap<String, Integer> map = new ArrayMap<>(); map.put("key1", 1); map.put("key2", 2); int value1 = map.get("key1"); int value2 = map.get("key2"); 2. Use TextUtilsCompat for text operations: boolean isEmpty = TextUtilsCompat.isEmpty("text"); boolean isDigitsOnly = TextUtilsCompat.isDigitsOnly("123"); String concatenatedText = TextUtilsCompat.concat("Hello", " ", "World").toString(); 3. Use Pair for key value pairing operations: Pair<String, Integer> pair = new Pair<>("key", 1); String key = pair.first; int value = pair.second; The above are just some sample code. The Android Support Library Core Utilities framework provides more functions and classes for developers to use. For specific usage methods, please refer to the official documentation and sample code. summary This article introduces the updated content and usage methods of the Android Support Library Core Utilities framework.
