Dialog problem: requestFeature() must be called before adding content

Question

I\'m creating a custom dialog containing an EditText so that I can get text data from the user:

final EditText newKey = (EditText) findViewById(R.id.dialog_r         


        

Answer 1

This also happens if you try to access any view item with findViewById() before the onCreate() That is in my case i did:

 private class ShareViaDialog extends Dialog  {
 private ImageView mainSmallIcon = findViewById(R.id.mainSmallIcon);    //this is wrong
  @Override
        protected void onCreate(Bundle savedInstanceState) {
            requestWindowFeature(Window.FEATURE_NO_TITLE);
            super.onCreate(savedInstanceState);
}}

so the correct way to avoid this error is:

 private class ShareViaDialog extends Dialog  {
     private ImageView mainSmallIcon;
      @Override
            protected void onCreate(Bundle savedInstanceState) {
                requestWindowFeature(Window.FEATURE_NO_TITLE);
                super.onCreate(savedInstanceState);
mainSmallIcon = findViewById(R.id.mainSmallIcon); //should be here
    }}
