Actually i solved this problem but somehow after a few hours of coding now its doing the same thing.cant figure what is wrong but it crashes every time at the popup_durum is executed. The code works fine when i add it to the same class but in seperate class it crashes and i need to call this function in every page any help will be appritiated thanx advance.
This is the class i callpublic class Antreman extends AppCompatActivity {AlertDialog.Builder dialogBuilder;Button AntremanaBasla,Cikis;View popup_durum;//Pop up----------------------------------------------------------------------------------------public void AntremanSayfasi(){ dialogBuilder = new AlertDialog.Builder(this); popup_durum = getLayoutInflater().inflate(R.layout.popup_durum,null); AntremanaBasla = popup_durum.findViewById(R.id.basla); Cikis = popup_durum.findViewById(R.id.cikis); dialogBuilder.setView(popup_durum); AlertDialog dialog = dialogBuilder.create(); dialog.show(); AntremanaBasla.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { dialog.dismiss(); } }); Cikis.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { dialog.dismiss(); } });}and this is the call function
public class Login extends AppCompatActivity {@Overrideprotected void onCreate(Bundle savedInstanceState) { ----------- Antreman antreman = new Antreman(); logoImage = (ImageView) findViewById(R.id.logologin); logoImage.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { antreman.AntremanSayfasi(); } });}}
