Here is my json URL https://jsonplaceholder.typicode.com/todos I want to display only completed: true is to be strike through, how can I do that?

MainActivity.java

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("https://jsonplaceholder.typicode.com/")
        .addConverterFactory(GsonConverterFactory.create())
        .build();

JsonPlaceHolderApi jsonPlaceHolderApi = retrofit.create(JsonPlaceHolderApi.class);

Call<List<Post>> call = jsonPlaceHolderApi.getPosts();

call.enqueue(new Callback<List<Post>>() {
    @Override
    public void onResponse(Call<List<Post>> call, Response<List<Post>> response) {
        if (!response.isSuccessful()) {
            textresult.setText("Code: " + response.code());
            return;
        }
        List<Post> posts = response.body();
        for (Post post : posts) {
            String content = "";
            content += "User ID: " + post.getUserId() + "\n";
            content += "ID: " + post.getId() + "\n";
            content += " Title: " + post.getTitle() + "\n";
            content += "Completed: " + post.getCompleted() + "\n\n";

            textresult.append(content);

            if (post.getCompleted().contains("true")) {
                textresult.setPaintFlags(textresult.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
            }
        }
    }
    @Override
    public void onFailure(Call<List<Post>> call, Throwable t) {
        textresult.setText(t.getMessage());
    }
});

JsonPlaceHolderApi.java

public interface JsonPlaceHolderApi {

    @GET("todos")                

    Call<List<Post>> getPosts();       


}

Post.java

public class Post {

    private int userId;

    private int id;

    private String title;

    private String completed;

    public int getUserId() {
        return userId;
    }

    public int getId() {
        return id;
    }

    public String getTitle() {
        return title;
    }

    public String getCompleted() {
        return completed;
    }
}

When I try to run the above code I got output as image, but I need if completed: true it should be strike.

it is not possible to do setPaintFlags() with custom text better use can use HTML text for your work for you don't need to check "post.complete()", just append all content in a single string and replace your target string (complete: true) with HTML text.

just do it like

     String content = "";
        for (Post post : posts) {
        content += "User ID: " + post.getUserId() + "\n";
        content += "ID: " + post.getId() + "\n";
        content += " Title: " + post.getTitle() + "\n";
        content += "Completed: " + post.getCompleted() + "\n\n";
 }

 String tempHtmlText = content.replaceAll("Completed: true","<strike>Completed: true</strike>");

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        textresult.setText(Html.fromHtml(tempHtmlText , Html.FROM_HTML_MODE_LEGACY));
    } else {
        textresult.setText(Html.fromHtml(tempHtmlText));
    }

or you can use Gson formmater
