如何从.NET Web Service获取马拉地语数据到Spinner？TextView字体问题求助

Hey there! Let's break down solutions for your two Android development problems:

First, let's make sure we're handling character encoding correctly—Marathi uses Unicode, so your app and the web service need to communicate in UTF-8. Here's a step-by-step approach:

• Step 1: Ensure UTF-8 support in your network request
  When calling your .NET Web Service, explicitly set the request to accept UTF-8 responses. For example, using HttpURLConnection:

  HttpURLConnection conn = (HttpURLConnection) url.openConnection();
  conn.setRequestProperty("Accept-Charset", "UTF-8");
  conn.setRequestMethod("GET");
  

  On the .NET side, confirm your Web Service is configured to output UTF-8 (check that the response content type includes charset=utf-8—this fixes most garbled text issues).

• Step 2: Parse the JSON response
  Use a JSON parser (like JSONObject or Gson) to extract the SchemeName values from the Get_DepoScheme array. Here's an example with JSONObject:

  String jsonResponse = // Your web service response string
  JSONObject rootObj = new JSONObject(jsonResponse);
  JSONArray schemeArray = rootObj.getJSONArray("Get_DepoScheme");
  
  List<String> schemeNames = new ArrayList<>();
  for (int i = 0; i < schemeArray.length(); i++) {
      JSONObject schemeObj = schemeArray.getJSONObject(i);
      // Extract the Marathi scheme name directly (UTF-8 is supported natively)
      String marathiName = schemeObj.getString("SchemeName");
      schemeNames.add(marathiName);
  }
  

• Step 3: Attach the data to your Spinner
  Create an ArrayAdapter and bind it to your Spinner. Android supports UTF-8 text by default, so no extra configuration is needed here:

  Spinner spinner = findViewById(R.id.your_spinner_id);
  ArrayAdapter<String> adapter = new ArrayAdapter<>(this, 
          android.R.layout.simple_spinner_item, schemeNames);
  adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
  spinner.setAdapter(adapter);
  

If setting the custom font in onCreate isn't working, here are the most common fixes:

• Check your font file location
  Make sure your font file (e.g., marathi_font.ttf) is placed in the assets/fonts/ directory. Android is case-sensitive, so double-check the filename matches exactly what you're referencing in code.

• Verify Typeface initialization
  Ensure you're loading the font correctly. Here's the proper way:

  TextView textView = findViewById(R.id.your_textview_id);
  Typeface customFont = Typeface.createFromAsset(getAssets(), "fonts/marathi_font.ttf");
  textView.setTypeface(customFont);
  

  If you're using a Material Components theme, check if your theme's default text style is overriding the font—you may need to explicitly set the font in your layout XML or create a custom text style that inherits your font.

• Use a Custom TextView for consistent results
  If your TextView has multiple states (pressed, selected) or is used across multiple screens, creating a custom TextView class ensures the font is applied everywhere:

  public class CustomFontTextView extends TextView {
      public CustomFontTextView(Context context) {
          super(context);
          initFont();
      }
  
      public CustomFontTextView(Context context, AttributeSet attrs) {
          super(context, attrs);
          initFont();
      }
  
      private void initFont() {
          Typeface customFont = Typeface.createFromAsset(getContext().getAssets(), "fonts/marathi_font.ttf");
          setTypeface(customFont);
      }
  }
  

  Then use this custom TextView in your layout:

  <com.yourpackage.CustomFontTextView
      android:id="@+id/your_textview_id"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="मुदत ठेव"/>
  

• Check for RecyclerView/ListView scenarios
  If your TextView is inside a RecyclerView or ListView, don't set the font in onCreate—instead, apply it in the onCreateViewHolder method of your adapter, so each list item gets the font correctly.
