按钮位置

Question

我希望fillmeup按钮低于JButtons说 setBackground( new Color(130,50,40) ); setLayout( new BorderLayout(3,3) ); BlackjackCanvas board = new BlackjackCanvas(); add(board, BorderLayout.CENTER); Panel buttonPanel = new Panel(); buttonPanel.setBackground(new Color(220,200,180)); add(buttonPanel, BorderLayout.SOUTH); Panel buttonPane2 = new Panel(); buttonPane2.setBackground(new Color(220,200,180)); add(buttonPane2, BorderLayout.EAST); Panel buttonPane3 = new Panel(); buttonPane3.setBackground(new Color(220,200,180)); add(buttonPane3, BorderLayout.WEST); Button hit = new Button( "Hit!" ); hit.addActionListener(board); hit.setBackground(Color.lightGray); buttonPanel.add(hit); Button stand = new Button( "Stand!" ); stand.addActionListener(board); stand.setBackground(Color.lightGray); buttonPanel.add(stand); Button newGame = new Button( "New Game" ); newGame.addActionListener(board); newGame.setBackground(Color.lightGray); buttonPanel.add(newGame); JLabel money = new JLabel( "Fill me up!" ); money.setBackground(Color.lightGray); buttonPane2.add(money); Button money1 = new Button( "A rare commodity" ); newGame.addActionListener(board); newGame.setBackground(Color.lightGray); buttonPane2.add(money1); ，但当我尝试添加按钮时，它会移到标签右侧而不是它下面。我正在使用applet并使用 private void setAlarm(Calendar targetCal) { deleteCopy(); info.setText("\n\n***\n" + "Alarm is set @ " + targetCal.getTime() + "\n" + "***\n"); Intent intent = new Intent(getBaseContext(), AlarmReceiver.class); pendingIntent = PendingIntent.getBroadcast(getBaseContext(), RQS_1, intent, 0); alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE); alarmManager.set(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(), pendingIntent); Intent alarmIIntent = new Intent(this, AlarmReceiver.class); Intent intent_ForResult = new Intent(TimeDateRem.this, MainActivity.class); startActivity(intent_ForResult);} public void deleteCopy() { Cursor cursor = dba.getnameofAlarm(title.getText().toString()); if (cursor.moveToFirst()) { final DatabaseActivity dba= new DatabaseActivity(getApplicationContext()); String titleData=(cursor.getString(cursor.getColumnIndex(Constants.COLUMN_NAME))); if(title.getText().toString().matches(titleData)) { AlertDialog.Builder builder = new AlertDialog.Builder(TimeDateRem.this); builder.setTitle("Set Alarm"); builder.setMessage("By setting this alarm you will be deleting the previous one, is that OK?") .setCancelable(false) .setPositiveButton("OK", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { dba.deleteAlarm(title.getText().toString().trim()); } }) .setNegativeButton("Cancel", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { dialog.cancel(); } }); AlertDialog alertDialog = builder.create(); alertDialog.show(); } cursor.close(); } 。任何建议将不胜感激。

我会考虑参考这里的文档Java Layout Options

将buttonPane2布局管理器设置为满足您需求的布局管理器。

这可以使用setLayout（new xxxLayout（））;

来完成
