LruCache類屬於android.support.v4.util包，在下文中一共展示了LruCache類的15個代碼示例，這些例子默認根據受歡迎程度排序。您可以為喜歡或者感覺有用的代碼點讚，您的評價將有助於係統推薦出更棒的Java代碼示例。

示例1: initialize

import android.support.v4.util.LruCache; //導入依賴的package包/類
public static synchronized void initialize(Configuration configuration) {
	if (sIsInitialized) {
		Log.v("ActiveAndroid already initialized.");
		return;
	}

	sContext = configuration.getContext();
	sModelInfo = new ModelInfo(configuration);
	sDatabaseHelper = new DatabaseHelper(configuration);

	// TODO: It would be nice to override sizeOf here and calculate the memory
	// actually used, however at this point it seems like the reflection
	// required would be too costly to be of any benefit. We'll just set a max
	// object size instead.
	sEntities = new LruCache<String, Model>(configuration.getCacheSize());

	openDatabase();

	sIsInitialized = true;

	Log.v("ActiveAndroid initialized successfully.");

    // Use 1/8th of the available memory for this memory cache.
