Well, I want you to choose the data to display between the dates he chooses. I tried everything but I still could not.

In other words, I want to filter between dates, but the user has to choose them. I already managed with an SQL command, but it was manual. I wanted you to choose the dates. Thanks!

Code:

input.java

private EditText DataEdit; private EditText editDescricao; private Button botaoadicionar; private Button botaover; static EditText DateEdit; private SQLiteDatabase db;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.input);
    createDatabase();

    DataEdit = (EditText) findViewById(R.id.iEditdata);
    editDescricao = (EditText) findViewById(R.id.ieditDescricao);
    botaoadicionar = (Button) findViewById(R.id.botaoadicionar);
    botaover = (Button) findViewById(R.id.botaover);
    botaoadicionar.setOnClickListener(this);
    botaover.setOnClickListener(this);
    DateEdit = (EditText) findViewById(R.id.iEditdata);
    DateEdit.setOnClickListener(new View.OnClickListener() {
        // ver se fiz asneira...
        public void onClick(View v) {

            showTruitonDatePickerDialog(v);
        }
    });
}

protected void createDatabase(){
    db=openOrCreateDatabase("DadosDB", Context.MODE_PRIVATE, null);
    db.execSQL("CREATE TABLE IF NOT EXISTS tabeladados(id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, data DATE,descricao VARCHAR);");
}
protected void insertIntoDB(){
    String data = DataEdit.getText().toString().trim();
    String descricao = editDescricao.getText().toString().trim();
    if(data.equals("") || descricao.equals("")){
        Toast.makeText(getApplicationContext(),"Preencha todos os campos", Toast.LENGTH_LONG).show();
        return;
    }

    String query = "INSERT INTO tabeladados (data,descricao) VALUES('"+data+"', '"+descricao+"');";
    db.execSQL(query);
    Toast.makeText(getApplicationContext(),"Guardado com sucesso", Toast.LENGTH_LONG).show();
}

        final Calendar c = Calendar.getInstance();
        int year = c.get(Calendar.YEAR);
        int month = c.get(Calendar.MONTH);
        int day = c.get(Calendar.DAY_OF_MONTH);

        return new DatePickerDialog(getActivity(), this, year, month, day);
    }

    public void onDateSet(DatePicker view, int year, int month, int day) {

        DateEdit.setText(year + "-" + (month + 1) + "-" + day);

How it works:

SELECT *
FROM tabela
WHERE datapesquisada BETWEEN '2017-01-01' AND '2017-12-31';

As Reginaldo said above, creating a button can solve this problem.

You create the text boxes for the user to enter and then you will get this value to search the database.

I'm not sure about the syntax but it should be something like this:

@Override
public void onClick(View v) {
   String dataInicial = (EditText)findViewById(R.id.dataInicial);
   String dataFinal = (EditText)findViewById(R.id.dataFinal); // EditText é só um exemplo

   String query = "SELECT * FROM tabela 
   WHERE data BETWEEN " + dataInicial + " AND " + dataFinal;
   // aqui será o código para executar a query à BD.
   Cursor c = db.rawQuery(query, null);
   // depois terás de efetuar o tratamento dos dados
}
