在 Android Gradle 插件版本 8.0 中，资源 ID 默认为非最终的，避免在 switch case 语句中使用它们

Question

我在 Android Studio 中收到关于我的导航抽屉资源的警告。警告是 Resource IDs will be non-final by default in Android Gradle Plugin version 8.0, avoid using them in switch case statements。我尝试使用方法 if 来更新我的代码，但我不会 'converted right'。我在互联网上发现这个 article 可以帮助我转换我的代码，但它似乎对我不起作用。我想知道我是否遗漏了什么。

下面是之前和之后的想法，here是我的完整activity因为我看到很多人用过后都有这个public void onClick...而我没有使用它。我有 navigationView.setNavigationItemSelectedListener(menuItem -> {.

Before:

navigationView.setNavigationItemSelectedListener(menuItem -> {
switch (menuItem.getItemId())
            {
                case R.id.nav_drawer_settings:
                    Intent intent = new Intent (MainActivity.this, SettingsActivity.class);
                    startActivity(intent);
                    break;
                case R.id.nav_drawer_whitelist:
                    intent = new Intent (MainActivity.this, WhitelistActivity.class);
                    startActivity(intent);
                    break;
                case R.id.nav_drawer_clipboard_cleaner:
                    intent = new Intent (MainActivity.this, ClipboardActivity.class);
                    startActivity(intent);
                    break;
                case R.id.nav_drawer_invalid_media_cleaner:
                    intent = new Intent (MainActivity.this, InvalidActivity.class);
                    startActivity(intent);
                    break;
                case R.id.nav_drawer_about:
                    intent = new Intent (MainActivity.this, AboutActivity.class);
                    startActivity(intent);
                    break;
                case R.id.nav_drawer_support:
                    Intent newIntent = new Intent(android.content.Intent.ACTION_VIEW,
                            Uri.parse("https://www.paypal.me/d4rkmichaeltutorials"));
                    startActivity(newIntent);
                    break;
                case  R.id.nav_drawer_share:{
                    Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
                    sharingIntent.setType("text/plain");
                    String shareBody =  "https://play.google.com/store/apps/details?id=com.d4rk.cleaner";
                    sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"Try right now!");
                    sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
                    startActivity(Intent.createChooser(sharingIntent, "Share using..."));
                }
                break;
            }
            return false;
        });
    }

After:

navigationView.setNavigationItemSelectedListener(menuItem -> {
switch (view.getId()) {
                if (item.getItemId() == R.id.nav_drawer_settings) {
                    Intent intent = new Intent (MainActivity.this, SettingsActivity.class);
                    startActivity(intent);
                }
                if (item.getItemId() == R.id.nav_drawer_whitelist) {
                    Intent intent = new Intent (MainActivity.this, WhitelistActivity.class);
                    startActivity(intent);
                }
                if (item.getItemId() == R.id.nav_drawer_clipboard_cleaner) {
                    Intent intent = new Intent (MainActivity.this, ClipboardActivity.class);
                    startActivity(intent);
                }
                if (item.getItemId() == R.id.nav_drawer_invalid_media_cleaner) {
                    Intent intent = new Intent (MainActivity.this, InvalidActivity.class);
                    startActivity(intent);
                }
                if (item.getItemId() == R.id.nav_drawer_about) {
                    Intent intent = new Intent (MainActivity.this, AboutActivity.class);
                    startActivity(intent);
                }
                if (item.getItemId() == R.id.nav_drawer_support) {
                    Intent openURL = new Intent(Intent.ACTION_VIEW);
                    openURL.setData(Uri.parse("https://www.paypal.me/d4rkmichaeltutorials"));
                    startActivity(openURL);
                }
                if (item.getItemId() == R.id.nav_drawer_share) {
                    Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
                    sharingIntent.setType("text/plain");
                    String shareBody =  "https://play.google.com/store/apps/details?id=com.d4rk.cleaner";
                    sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"Try right now!");
                    sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
                    startActivity(Intent.createChooser(sharingIntent, "Share using..."));
                }
            }
            return false;
        });
    }

提前致谢！ :D

在您发布的后续代码中，不再需要开关。

它应该只通过编写以下内容工作：

            if (item.getItemId() == R.id.nav_drawer_settings) {
                Intent intent = new Intent (MainActivity.this, SettingsActivity.class);
                startActivity(intent);
            }
            if (item.getItemId() == R.id.nav_drawer_whitelist) {
                Intent intent = new Intent (MainActivity.this, WhitelistActivity.class);
                startActivity(intent);
            }
            if (item.getItemId() == R.id.nav_drawer_clipboard_cleaner) {
                Intent intent = new Intent (MainActivity.this, ClipboardActivity.class);
                startActivity(intent);
            }
            if (item.getItemId() == R.id.nav_drawer_invalid_media_cleaner) {
                Intent intent = new Intent (MainActivity.this, InvalidActivity.class);
                startActivity(intent);
            }
            if (item.getItemId() == R.id.nav_drawer_about) {
                Intent intent = new Intent (MainActivity.this, AboutActivity.class);
                startActivity(intent);
            }
            if (item.getItemId() == R.id.nav_drawer_support) {
                Intent openURL = new Intent(Intent.ACTION_VIEW);
                openURL.setData(Uri.parse("https://www.paypal.me/d4rkmichaeltutorials"));
                startActivity(openURL);
            }
            if (item.getItemId() == R.id.nav_drawer_share) {
                Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
                sharingIntent.setType("text/plain");
                String shareBody =  "https://play.google.com/store/apps/details?id=com.d4rk.cleaner";
                sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"Try right now!");
                sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
                startActivity(Intent.createChooser(sharingIntent, "Share using..."));
            }

在 Android Gradle 插件版本 8.0 中，资源 ID 默认为非最终的，避免在 switch case 语句中使用它们
