自定义警报对话框未定义方法

Question

i am new to android and i am trying to get this custom dialog to work, i get an error on showDialog & removeDialog which says The method removeDialog(int) is undefined for the type new DialogInterface.OnClickListener .

onReceive method:

showDialog(DIALOG_TEXT_ENTRY);

Code:

    private static final int MY_PASSWORD_DIALOG_ID = 0;

    MediaPlayer mp;
    Context context;   

    protected Dialog onCreateDialog(int id, Context context) {

        Dialog dialog = null;
        switch(id) {
        case MY_PASSWORD_DIALOG_ID:
            LayoutInflater factory = LayoutInflater.from(context);

            final View textEntryView = factory.inflate(R.layout.password_dialog, null);

            final EditText password1 = (EditText) textEntryView.findViewById(R.id.inputPassword);

            AlertDialog.Builder builder = new AlertDialog.Builder(context);
            builder.setTitle("Enter Password");
            builder.setView(textEntryView);

            builder.setPositiveButton(android.R.string.cancel, new DialogInterface.OnClickListener() {
                   public void onClick(DialogInterface dialog, int whichButton) {
                      removeDialog(MY_PASSWORD_DIALOG_ID);
                   }
                });

                AlertDialog passwordDialog = builder.create();
                return passwordDialog; 
        }
        return null;
    }

Answer 1

use

dialog.dismiss();

instead of

removeDialog(MY_PASSWORD_DIALOG_ID);

you cant show a dialog in a BroadcastReceiver.

but still, if you want to show a popup screen, then create an activity, with Dialog theme.

Answer 2

You can also use

builder.setPositiveButton(android.R.string.cancel, new DialogInterface.OnClickListener() {
                   public void onClick(DialogInterface dialog, int whichButton) {
                       dialog.cancel(); 
                   }
                });

on button click it should work fine

Answer 3

you should use dialog.dismiss(); instead of your removeDialog() method.

Answer 4

See below. Use dismiss();

builder.setPositiveButton(android.R.string.cancel, new DialogInterface.OnClickListener() {
   public void onClick(DialogInterface dialog, int whichButton) {
      dismiss();
   }
};

Call this way showDialog(MY_PASSWORD_DIALOG_ID);

Refer this Create Custom Dialog tutorial

@Override
protected Dialog onCreateDialog(int id) {
 // TODO Auto-generated method stub

 screenDialog = null;
 switch(id){
 case(ID_SCREENDIALOG):
  screenDialog = new Dialog(this);
  screenDialog.setContentView(R.layout.screendialog);
  bmImage = (ImageView)screenDialog.findViewById(R.id.image);
  TextOut = (TextView)screenDialog.findViewById(R.id.textout);
  btnScreenDialog_OK = (Button)screenDialog.findViewById(R.id.okdialogbutton);
  btnScreenDialog_OK.setOnClickListener(btnScreenDialog_OKOnClickListener);
 }
 return screenDialog;
}
