为什么应用中没有显示正负按钮？你们有什么想法要改变吗？感谢。

button2.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Vibrator vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE);
                    vibrator.vibrate(100);

                    AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
                    builder.setTitle("Berühre mich noch einmal und du wirst's bereuen!!");
                    builder.setPositiveButton("OK sorry", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            Toast.makeText(MainActivity.this, "Sorry Herr Gauß! ", Toast.LENGTH_LONG).show();
                        }

                    });
                    builder.setNegativeButton("Mir egal.", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            Toast.makeText(MainActivity.this, "Mehr als vibrieren kannst du eh nicht!", Toast.LENGTH_LONG).show();
                        }
                    });
                    builder.create().show();
                    AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(MainActivity.this, R.style.MyDialogTheme);
                         }
            }

删除创建新对话框的最后一行，再次在创建对话框上设置主题

 button2.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Vibrator vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE);
                    vibrator.vibrate(100);

                    AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this, R.style.MyDialogTheme);
                    builder.setTitle("Berühre mich noch einmal und du wirst's bereuen!!");
                    builder.setPositiveButton("OK sorry", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            Toast.makeText(MainActivity.this, "Sorry Herr Gauß! ", Toast.LENGTH_LONG).show();
                        }

                    });
                    builder.setNegativeButton("Mir egal.", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            Toast.makeText(MainActivity.this, "Mehr als vibrieren kannst du eh nicht!", Toast.LENGTH_LONG).show();
                        }
                    });
                    builder.create().show();

                         }
            }

试试这个：

new AlertDialog.Builder(MainActivity.this)
                    .setPositiveButton("OK sorry", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which)
                        {
                            Toast.makeText(MainActivity.this, "Sorry Herr Gauß! ", Toast.LENGTH_LONG).show();
                        }
                    })
                    .setNegativeButton("No", null)
                    .setTitle("Berühre mich noch einmal und du wirst's bereuen!!")
                    .setMessage("Hello world")
                    .show();

对话框不显示正面和负面按钮？
