I'm trying to load an image in a ImageView , but the image I'm trying to upload is from a URL. The method that loads the image is called cargarDatos() I put it in the OnCreate() so that the image is displayed once the Activity is loaded.
I am using a thread to make the connection to the URL.
This is the activity code.
public class MainMenuUsuario extends AppCompatActivity {
private ImageView img;
private Bitmap loadedImage;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.pestanias_usuario);
crearPestanias();
cargarDatos();
}
public void cargarDatos(){
cd.start(); ///Aquí tengo el error.
}
Thread cd=new Thread(new Runnable() {
@Override
public void run() {
img=(ImageView)findViewById(R.id.imageView2);
URL imageUrl = null;
try {
imageUrl = new URL("http://192.168.150.101:8080/TDIDP/imagenes/IMG-20173175029");
HttpURLConnection conn = (HttpURLConnection) imageUrl.openConnection();
conn.connect();
loadedImage = BitmapFactory.decodeStream(conn.getInputStream());
img.setImageBitmap(loadedImage);
} catch (IOException e) {
Toast.makeText(getApplicationContext(), "Error cargando la imagen: "+e.getMessage(), Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
});
public void crearPestanias(){
TabHost host = (TabHost)findViewById(R.id.tabHost);
host.setup();
TabHost.TabSpec spec = host.newTabSpec("Tab One");
spec.setContent(R.id.inicio);
spec.setIndicator("Inicio");
host.addTab(spec);
spec = host.newTabSpec("Ventas");
spec.setContent(R.id.Ventas);
spec.setIndicator("Ventas");
host.addTab(spec);
spec = host.newTabSpec("Compras");
spec.setContent(R.id.Compras);
spec.setIndicator("Compras");
host.addTab(spec);
}
}
This has the layout.
