java - 如何在Android中使用Settings.Global、Settings.Secure和Settings.System？

Question

我想使用上面提到的类，并想从它们的静态常量中检索信息。我想检索这样的信息。例如来自 Settings.Secure

SETTINGS_SECURE
ADB_ENABLED=1
ALLOWED_GEOLOCATION_ORIGINS=http://www.google.co.uk 
ALLOW_MOCK_LOCATION=0
ANDROID_ID=200142d4dfd4e641

但我实际上得到了这个输出:

SETTINGS_SECURE
ADB_ENABLED=adb_enabled
ALLOWED_GEOLOCATION_ORIGINS=allowed_geolocation_origins
ALLOW_MOCK_LOCATION=allow_mock_location
ANDROID_ID=android_id

有什么建议吗？

看起来您只是在检索常量的值。作为一个简单的例子来说明差异，产生上述输出:

StringBuilder sb = new StringBuilder("SETTINGS_SECURE\n");

sb.append(Settings.Secure.ADB_ENABLED.toUpperCase())
    .append("=")
    .append(Settings.Secure.getString(getContentResolver(),
        Settings.Secure.ADB_ENABLED))
    .append("\n")

    .append(Settings.Secure.ALLOWED_GEOLOCATION_ORIGINS.toUpperCase())
    .append("=")
    .append(Settings.Secure.getString(getContentResolver(),
        Settings.Secure.ALLOWED_GEOLOCATION_ORIGINS))
    .append("\n")

    .append(Settings.Secure.ALLOW_MOCK_LOCATION.toUpperCase())
    .append("=")
    .append(Settings.Secure.getString(getContentResolver(),
        Settings.Secure.ALLOW_MOCK_LOCATION))
    .append("\n")

    .append(Settings.Secure.ANDROID_ID.toUpperCase())
    .append("=")
    .append(Settings.Secure.getString(getContentResolver(),
        Settings.Secure.ANDROID_ID));
