我在使用Holoeverywhere的AlertDialog上使用setTitle时收到错误...

java.lang.ClassCastException: org.holoeverywhere.app.Dialog$DialogTitle cannot be cast to org.holoeverywhere.widget.TextView

这是我的代码：

AlertDialog.Builder builder = new AlertDialog.Builder(this);
                    builder.setTitle("Choose Crop App");
                    builder.setAdapter( adapter, new DialogInterface.OnClickListener() {
                        public void onClick( DialogInterface dialog, int item ) {
                            startActivityForResult( cropOptions.get(item).appIntent, CROP_FROM_CAMERA);
                        }
                    });

                    builder.setOnCancelListener( new DialogInterface.OnCancelListener() {
                        @Override
                        public void onCancel( DialogInterface dialog ) {

                            if (mImageCaptureUri != null ) {
                                getContentResolver().delete(mImageCaptureUri, null, null );
                                mImageCaptureUri = null;
                            }
                        }
                    } );

builder.setTitle("Choose Crop App");

时出错

我该如何解决？

请使用AlertDialog，如下所示

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
                this);

            // set title
            alertDialogBuilder.setTitle("Your Title");

            // set dialog message
            alertDialogBuilder
                .setMessage("Click yes to exit!")
                .setCancelable(false)
                .setPositiveButton("Yes",new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog,int id) {
                        // if this button is clicked
                                    //write code for the click of yes button
                    }
                  })
                .setNegativeButton("No",new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog,int id) {
                        // if this button is clicked
                                         //write code for the click of No button
                    }
                });

                // create alert dialog
                AlertDialog alertDialog = alertDialogBuilder.create();

                // show it
                alertDialog.show();
