How do I read a .txt file that is written in rows and check if a line in that file has a value if you make a check in checkbox .
Example:
123
234
2456
If you have the file 123 , check the checkbox 123 , I do not need the file txt to be visible to the user I just need the code to read it.
To read a .txt from android, you can use the following code:
try {
AssetManager assetManager = getResources().getAssets();
InputStream inputStream = assetManager.open("nome-do-arquivo.txt");
InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
String linha;
LinkedList<String> linhas = new LinkedList<String>();
while((linha = bufferedReader.readLine())!=null){
//aqui com o valor da linha vc pode testar o que quiser, por exemplo: linha.equals("123")
linhas.add(linha);
}
inputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
