AutoSharedPreference

AutoSharedPreference is an automatic generation of SharedPreference by adding Annotations to class.

Usage

build.gradle

implementation 'me.linkaipeng:autoSPAnnotation:1.0.0'
annotationProcessor 'me.linkaipeng:autoSPCompiler:1.0.0'

Initialize

AutoSharedPreferenceConfig.getInstance().init(this);

Add annotations to the class

@AutoSharedPreferences(mode = Context.MODE_PRIVATE)
public class AppConfig {

    @AutoGenerateField(filedName = "StudentName", defaultStringValue = "ddd", commitType = AutoGenerateField.CommitType.APPLY)
    private String name;

    @AutoGenerateField(defaultIntValue = -10)
    private int count;

    @AutoGenerateField(defaultLongValue = 90l, commitType = AutoGenerateField.CommitType.COMMIT)
    private long startTime;

    @AutoGenerateField(defaultBooleanValue = true)
    private boolean isClose;

    @AutoGenerateField(defaultFloatValue = 0.534534534f)
    private float price;

    @AutoGenerateField
    private Set<String> productSet;
}

• mode can use the value in Context；
• If you want to customize the SharedPreferences filename, you can use the name attribute.。

Add annotations to the field

@AutoGenerateField(filedName = "StudentName", defaultStringValue = "ddd", commitType = AutoGenerateField.CommitType.APPLY)
private String name;

• filedName is used to define the name of key stored in SharedPreferences. The default value is the field name；
• defaultStringValue, defaultIntValue are used to set default values；
• commitType is the save mode, you can choose commit or apply, the default value is commit.

  private SharedPreferences mSharedPreferences;

  private AppConfigSP() {
    mSharedPreferences = AutoSharedPreferenceConfig.getInstance().getContext().getSharedPreferences("AppConfigSP", 0);
  }

  public static AppConfigSP getInstance() {
    if (null == sInstance) {
        sInstance = new AppConfigSP();
        }
        return sInstance;
  }

  public SharedPreferences getSharedPreferences() {
    return mSharedPreferences;
