Answer 1

把确认的默认focuseable设置为true

Answer 2

mAlertDlg.getButton(DialogInterface.BUTTON_POSITIVE).setFocusable(true); 
  mAlertDlg.getButton(DialogInterface.BUTTON_POSITIVE).setOnFocusChangeListener(mDialogOnFocusListener);
mAlertDlg.getButton(DialogInterface.BUTTON_POSITIVE).requestFocus();  
mAlertDlg.getButton(DialogInterface.BUTTON_POSITIVE).setSelected(true);
这些我都试过了！就是不行！  感觉在对话框上做动作 没用
