studio - obtener imagen almacenada en mysql desde android

vista de imagen creada dinámicamente en gridlayout no funciona

Question

Quiero establecer la imagen capturada en la vista de imagen creada dinámicamente en la misma distribución de cuadrícula, pero crea una nueva disposición de cuadrícula y establece la imagen capturada en la nueva vista de cuadrícula.

Answer 1

En primer lugar, parece que no está utilizando el patrón del titular en su CustomAdapter_back también cuando Fllo notó que no necesita eliminar manualmente las vistas. agregue esta función a su adaptador

public void setData(ArrayList<Damage_Item> data)
{
this.Damage_Item = Damage_Item;
notifyDataSetChanged();
}

y llame a esta función desde el diálogo

 AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("Whould you like to delete this image?");
builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//get deleted item index according to your logic
int index = ((View) v.getParent()).getId() + 2;
gridArray.remove(index);
customGridAdapter.setData(gridArray);
Toast.makeText(getApplicationContext(), "delete", Toast.LENGTH_LONG).show();
}
});

Answer 2

Intente cambiar su xml quitando el GridView ya que la distribución de la parrilla debería cambiar el tamaño de la imagen automáticamente. Otra solución no recomendada sería utilizar las dimensiones de la pantalla para dimensionar su imagen

Answer 3

Prueba esto

public class MainActivity extends Activity implements AdapterView.OnItemClickListener {
GridView gridView;
ArrayList<Damage_Item> gridArray = new ArrayList<Damage_Item>();
CustomAdapter_back customGridAdapter;

LinearLayout dynamic_linearview;
String image1;
ArrayList<String> arrayList_image = new ArrayList<String>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mContainerView = (GridLayout)findViewById(R.id.describedamage_gridview) ;
//gridArray.add(new Item(homeIcon,"Home"));
gridView = (GridView) findViewById(R.id.gridview1);

Answer 4

en ActivityResult tienes 2 líneas de código:

 customGridAdapter = new CustomAdapter_back(MainActivity.this, gridArray);
gridView.setAdapter(customGridAdapter);

de modo que cada vez que agrega una nueva imagen recrea el adaptador.

Simplemente mueva la declaración del adaptador a onCreate con la lista vacía. Agregar método

 public void addItem(Damage_Item item){
this.Damage_Item.add(item);
this.notifyDataSetChange();
}

a su adaptador y desencadenarlo en lugar de crear el adaptador y establecer nuevo dentro de su onCaptureImageResult.

Y por el amor de Dios, nombrando la convención. Tu código es ilegible
