Sto costruendo un'interfaccia utente, ed è tutto statico definito nell'XML. Tutto ha pesi dappertutto, e mentre sembra giusto, volevo vedere che le cose in realtà hanno la giusta altezza e tutto il resto. Il problema è che non importa dove chiamo .getHeight() per il mio layout di formato ho ottenuto 0. Ho provato sia su onCreate() che onStart(). Stessa cosa. Succede anche per tutti gli oggetti dell'interfaccia utente. Qualche idea?getHeight restituisce 0 per tutti gli oggetti dell'interfaccia utente Android
package com.app.conekta;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Window;
import android.widget.Button;
import android.widget.FrameLayout;
import android.widget.Toast;
public class Conekta extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
@Override
public void onStart() {
super.onStart();
}
@Override
public void onResume() {
super.onResume();
FrameLayout fl1 = (FrameLayout) findViewById(R.id.headerFrameLayout);
FrameLayout fl2 = (FrameLayout) findViewById(R.id.footerFrameLayout);
Button b=(Button) findViewById(R.id.searchButton);
Log.d("CONEKTA", String.valueOf(b.getHeight()));
}
}
