在SharedPreferences中保持整数不变

SharedPreferences sharedPreferences = context.getSharedPreferences("mySharedPreferences", Context.MODE_PRIVATE);

SharedPreferences.Editor editor = sharedPreferences.edit();

int intValue = 10;
editor.putInt("intValue", intValue);

editor.apply();

import android.content.Context;
import android.content.SharedPreferences;

public class MySharedPreferencesHelper {
    private static final String SHARED_PREFERENCES_NAME = "mySharedPreferences";
    private static final String KEY_INT_VALUE = "intValue";

    public static void saveIntValue(Context context, int value) {
        SharedPreferences sharedPreferences = context.getSharedPreferences(SHARED_PREFERENCES_NAME, Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = sharedPreferences.edit();
        editor.putInt(KEY_INT_VALUE, value);
        editor.apply();
    }

    public static int getIntValue(Context context) {
        SharedPreferences sharedPreferences = context.getSharedPreferences(SHARED_PREFERENCES_NAME, Context.MODE_PRIVATE);
        return sharedPreferences.getInt(KEY_INT_VALUE, 0);
    }
}
