这篇博客介绍了如何在RK3288平台的Android 6.0系统中，默认在user版本显示开发者选项。通常需要连续点击版本号7次才能显示，但通过修改SettingsActivity.java文件，可以设置开发者选项始终显示。

默认user版本不显示开发者选项这一栏,需要通过连续点击版本号7次来显示.
packages\apps\Settings\src\com\android\settings\DeviceInfoSettings.java

static final int TAPS_TO_BE_A_DEVELOPER = 7;

public void onResume() {
    super.onResume();
    mDevHitCountdown = getActivity().getSharedPreferences(DevelopmentSettings.PREF_FILE,
            Context.MODE_PRIVATE).getBoolean(DevelopmentSettings.PREF_SHOW,
                    android.os.Build.TYPE.equals("eng")) ? -1 : TAPS_TO_BE_A_DEVELOPER;
    mDevHitToast = null;
}

 public boolean onPreferenceTreeClick(PreferenceScreen preferenceScreen, Preference preference) {
 ......
     if (mDevHitCountdown > 0) {
        mDevHitCountdown--;
        if (mDevHitCountdown == 0) {
            getActivity().getSharedPreferences(DevelopmentSettings.PREF_FILE,
                    Context.MODE_PRIVATE).edit().putBoolean(
                            DevelopmentSettings.PREF_SHOW, true).apply();
            if (mDevHitToast != null) {
                mDevHitToast.cancel();
            }
            mDevHitToast = Toast.makeText(getActivity(), R.string.show_dev_on,
                    Toast.LENGTH_LONG);
            mDevHitToast.show();
            // This is good time to index the Developer Options
            Index.getInstance(
                    getActivity().getApplicationContext()).updateFromClassNameResource(
                            DevelopmentSettings.class.getName(), true, true);

        } else if (mDevHitCountdown > 0
                && mDevHitCountdown < (TAPS_TO_BE_A_DEVELOPER-2)) {
            if (mDevHitToast != null) {
                mDevHitToast.cancel();
            }
            mDevHitToast = Toast.makeText(getActivity(), getResources().getQuantityString(
                    R.plurals.show_dev_countdown, mDevHitCountdown, mDevHitCountdown),
                    Toast.LENGTH_SHORT);
            mDevHitToast.show();
        }
        } else if (mDevHitCountdown < 0) { //点击完7次之后显示
            if (mDevHitToast != null) {
                mDevHitToast.cancel();
            }
            mDevHitToast = Toast.makeText(getActivity(), R.string.show_dev_already,
                    Toast.LENGTH_LONG);
            mDevHitToast.show();
        }
    }
......
}

而默认开机是否显示由变量showDev控制
packages\apps\Settings\src\com\android\settings\SettingsActivity.java

private void updateTilesList(List<DashboardCategory> target) {
    final boolean showDev = mDevelopmentPreferences.getBoolean(
            DevelopmentSettings.PREF_SHOW,
            android.os.Build.TYPE.equals("eng"));    //因此eng才返回true
......
    } else if (id == R.id.development_settings) {
        if (!showDev || um.hasUserRestriction(
                UserManager.DISALLOW_DEBUGGING_FEATURES)) {
            removeTile = true;    //showDev为false则不显示
        }
    }
}

解决方法:
