android java读写yaml文件
import org.simpleyaml.configuration.file.YamlFile;
import org.yaml.snakeyaml.DumperOptions;
import org.yaml.snakeyaml.Yaml;private static void run() {File file new File(/data/data/com.xx/files/config.yaml);if (file.exists()) {YamlFile yamlFile new YamlFile(file);try {yamlFile.load();int debug yamlFile.getInt(debug, 1);
// Timber.i(debug: debug);Timber.i(debug: %s, debug);} catch (IOException e) {}}MapString, Object data new HashMap();data.put(name, John Doe);data.put(age, 30);DumperOptions options new DumperOptions();options.setDefaultFlowStyle(DumperOptions.FlowStyle.BLOCK);Yaml yaml new Yaml(options);try (FileWriter writer new FileWriter(path_to_your_file.yaml)) {yaml.dump(data, writer);} catch (IOException e) {e.printStackTrace();}}
写文件可以参考下面的java修改yaml文件 YamlFile
java修改yaml文件 YamlFile private void modfiy_param(String key ,int value) {File file new File(/data/data/com.xx/files/config.yaml);if (file.exists()) {YamlFile yamlFile new YamlFile(file);try {yamlFile.load();int track_delay yamlFile.getInt(aaa, 1);Timber.i(aaa: %s, aaa);yamlFile.set(key, value);yamlFile.save();} catch (IOException e) {e.printStackTrace();}}
}
修改yaml文件方法2 Yaml Yaml yaml new Yaml();MapString, Object data null;try {data yaml.load(new FileInputStream(/data/data/com.xx/files/config.yaml));// 2. 修改这个对象data.put(name, Jane Doe);
// MapString, Object data new HashMap();data.put(key, value);FileWriter writer new FileWriter(/data/data/com.xx/files/config.yaml);yaml.dump(data, writer);} catch (FileNotFoundException e) {throw new RuntimeException(e);} catch (IOException e) {throw new RuntimeException(e);}
删除值
import org.yaml.snakeyaml.Yaml;import java.io.FileInputStream;
import java.io.FileWriter;
import java.io.IOException;
import java.util.Map;public class Main {public static void main(String[] args) {deleteFromYamlFile(path_to_your_file.yaml, name);}public static void deleteFromYamlFile(String filePath, String key) {Yaml yaml new Yaml();try {// 1. 读取文件并将其解析为一个对象MapString, Object data yaml.load(new FileInputStream(filePath));// 2. 从这个对象中删除一个键data.remove(key);// 3. 将修改后的对象写回到文件FileWriter writer new FileWriter(filePath);yaml.dump(data, writer);writer.close();} catch (IOException e) {e.printStackTrace();}}
}
