error: requestFeature() must be called before addi

问题:

I know that similar questions have been asked in the past but I can't seem to get this working at all even with the suggestions.

I get the above abend on the "show()" command.

public void onCreate(Bundle savedInstanceState) { 
    try{

    super.onCreate(savedInstanceState);
    setContentView(R.layout.submitscoredummylayout);                
    scoreloopInit();
AlertDialog whatToUploadDialog;
whatToUploadDialog = new AlertDialog.Builder(YanivSubmitScoreActivity.this).create();
whatToUploadDialog.setContentView(R.layout.submitscoreprompt);
whatToUploadDialog.setTitle(R.string.uploadedScoreTitle);
whatToUploadDialog.setCancelable(false);


  ((CheckBox)whatToUploadDialog.findViewById(R.id.ckbScoreloop)).setChecked(settings.getUploadToSL());
  ((CheckBox)whatToUploadDialog.findViewById(R.id.ckbFacebook)).setChecked(settings.getUploadToFB());

  ((CheckBox) whatToUploadDialog.findViewById(R.id.ckbScoreloop)).setOnCheckedChangeListener(new OnCheckedChangeListener() { 

            @Override
            public void onCheckedChanged(CompoundButton ckBox, boolean isChecked) {
                settings.setUploadToSL(isChecked,true);
                findViewById(R.id.btnYes).setEnabled(isChecked||settings.getUploadToFB());
            }
            }); 

  ((CheckBox) whatToUploadDialog.findViewById(R.id.ckbFacebook)).setOnCheckedChangeListener(new OnCheckedChangeListener() { 

            @Override
            public void onCheckedChanged(CompoundButton ckBox, boolean isChecked) {
                settings.setUploadToFB(isChecked,true);
                findViewById(R.id.btnYes).setEnabled(isChecked||settings.getUploadToSL());
            }
         });        

  whatToUploadDialog.findViewById(R.id.btnYes).setOnClickListener(new OnClickListener() {
  @Override
      public void onClick(View v) {
                submitScore(SUBMIT_UPLOAD_TO_SL);
                whatToUploadDialog.dismiss();
      }
  });

  whatToUploadDialog.findViewById(R.id.btnNo).setOnClickListener(new OnClickListener() {
      @Override
          public void onClick(View v) {
                whatToUploadDialog.dismiss();
              finish();
          }
      });
whatToUploadDialog.show();
}

回答1:

I experienced the same problem. I found that the problem only occurs if I do both of the following things:

• I don't use activity managed dialogs (activity.showDialog() -> activity.onCreateDialog()/onPrepareDialog())

• I do dialog.findViewById() (and this is indeed the line difference between success or the requestFeature exception!).

final Builder dialogBuilder = new AlertDialog.Builder(activity);
b.setView(rootView);
b.setIcon(android.R.drawable.ic_dialog_info);
b.setTitle(R.string.message_of_the_day_title);
b.setCancelable(false);
dialog = b.createDialog();
dialog.findViewById(R.id.myid); // this is the problem

The dialog.findViewById() causes the problem because it calls

dialog.getWindow().getDecorView()

and the method javadoc of getDecorView() says:

Note that calling this function for the first time "locks in" various window characteristics as described in {@link #setContentView(View, android.view.ViewGroup.LayoutParams)}.

Isn't that nice, findViewById() has a side effect which causes seemingly correct applications to crash. Why there's a difference between Activity managed dialogs and normal dialogs I do not know, but I guess getDecorView() does some magic for Activity managed dialogs.

I did the above because I moved from using Activity managed dialogs to handling dialogs myself.

The solution for me is to manipulate the rootView, using rootView.findViewById(), instead of manipulating the dialog.

Substitude the following line:

whatToUploadDialog.setContentView(R.layout.submitscoreprompt);

with:

whatToUploadDialog.setView(R.layout.submitscoreprompt);

回答3:

Try calling

.setTitle(R.string.uploadedScoreTitle);

before

.setContentView(R.layout.submitscoreprompt);
