So it's complicated to ask, but anyway, this is the logic:
[
{ "name": "http://meusite/dados1.json"},
{ "name": "http://meusite/dados2.json", },
{ "name": "http://meusite/dados3.json"}
]
So as it was seen, I do not want to pass data straight from this main JSON, I want every data1.json information to appear in a recyclerView and data2.json appears in another division of the recyclerView. I will have to capture every link contained in "name" in a recyclerView and then extract the information contained in it, I want to work with multiple JSONs in just one screen. Hard work for me: / Logic does not enter the head. Here is the JSON code appearing in the recyclerView, but with data written directly. This is the basis!
PHP-embedded JSON file:
<?php echo json_encode(Array(Array( "song_name" => "Hero", "song_id" => "1990", "artist_name" => "Enrique"), Array("song_name" => "African Queen", "song_id" => "2004", "artist_name" => "Tuface"), Array("song_name" => "Ifunanyi", "song_id" => "2012", "artist_name" => "PSquare"))); ?>

public ItemObject(String songTitle, String songYear, String songAuthor) {
this.songTitle = songTitle;

this.songAuthor = songAuthor;
}
public String getSongTitle() {
return songTitle;
}
public String getSongYear() {

Finally, result:
Does anyone know how to do this? Many thanks!
