The textView that I'm currently using in my ListView is being displayed over and over, without changing it's information, but I'm not able to see why, can I get a litte help? Code:

Main code named Principal.java:

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.widget.ListView;



public class Principal extends AppCompatActivity {



ListView lista;



Stringdatos = {

        {"Mediciones del día"},

        {" "},

        {"Promedios del día"},

};



int  datosImg = {R.drawable.celeste, R.drawable.rojo, R.drawable.verde};



@Override

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_principal);



    lista = (ListView) findViewById(R.id.lvLista);



    lista.setAdapter(new Adaptador(this, datos, datosImg));

  }

}

My adapter:

import android.content.Context;

import android.content.Intent;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup; 

import android.widget.BaseAdapter;

import android.widget.ImageView;

import android.widget.TextView;



public class Adaptador extends BaseAdapter {



private static LayoutInflater inflater = null;



Context contexto;

String  datos;

int datosImg;



    public Adaptador (Context context, String  datos,int imagenes)

{

    this.contexto = context;

    this.datos = datos;

    this.datosImg = imagenes;

    inflater = 

(LayoutInflater)context.getSystemService(context.LAYOUT_INFLATER_SERVICE);

}



@Override

public View getView(int i, View convertView, ViewGroup parent) {



    final View vista = inflater.inflate(R.layout.elemento_lista, null);

    TextView titulo = (TextView) vista.findViewById(R.id.textView);

    ImageView imagen = (ImageView) vista.findViewById(R.id.imageView);



    titulo.setText(datos[0][0]);

    imagen.setImageResource(datosImg[i]);

    /*

    imagen.setTag(i);

    */

    /*

    imagen.setOnClickListener(new View.OnClickListener(){

      @Override

              public void onClick(View v){

         Intent visorImagen = new Intent(contexto, VisorImagen.class);

         visorImagen.putExtra("IMG", datosImg[(Integer)v.getTag()]);

         contexto.startActivity(visorImagen);

        }



    });

    */

    return vista;

}



@Override

public int getCount() {

    return datosImg.length;

}



@Override

public Object getItem(int position) {

    return null;

}



@Override

public long getItemId(int position) {

    return 0;

}

}

I have been looking for the solution for a really long time, but I haven't found anything online.

You could make the datos an array list like: ArrayList<String> and add elements with yourList.add(). Then in the adapter set the text to the TextView with titulo.setText(yourList.get(i).
Hope it helps!

I found the solution!, intead of

    titulo.setText(datos[i][0]);

    imagen.setImageResource(datosImg[i]);

I wrote:

    titulo.setText(datos[0][0]);

    imagen.setImageResource(datosImg[i]);

This means that it only shows 1 text, but the other one displays one text, and then goes to the next one. thanks for helping!

you are supposed to give position here, evrytime you set [0][0] will return the same value eveytime, do somthing like this.

public View getView(int i, View convertView, ViewGroup parent) {



    final View vista = inflater.inflate(R.layout.elemento_lista, null);

    TextView titulo = (TextView) vista.findViewById(R.id.textView);

    ImageView imagen = (ImageView) vista.findViewById(R.id.imageView);



    titulo.setText(datos[i][i]);

    imagen.setImageResource(datosImg[i]);

    /*

    imagen.setTag(i);

    */

    /*

    imagen.setOnClickListener(new View.OnClickListener(){

      @Override

              public void onClick(View v){

         Intent visorImagen = new Intent(contexto, VisorImagen.class);

         visorImagen.putExtra("IMG", datosImg[(Integer)v.getTag()]);

         contexto.startActivity(visorImagen);

        }



    });

    */

    return vista;

}
