已經閱讀了與此類似的舊問題，但他們都沒有幫助我解決問題。使用java更改/切換Windows 7輸入語言
操作系統：Windows 7 64位系統
語言輸入：
我想語言切換到馬拉雅拉姆語（印度）[Google Input tools]只有一個jTextField在Java Swing申請並切換回英語（美國）爲其餘領域。
UPDATE：
領域malyalamField是javax.swing.JTextField
javax.swing.JTextField malyalamField= new javax.swing.JTextField();
malyalamField.setFont(new java.awt.Font("Arial Unicode MS", 0, 12));
馬拉雅拉姆語（印度）：名爲喀拉拉邦南部印度國家使用的區域語言。
我試圖從Java上FocusGained和FocusGained事件
int keyInput[] = { KeyEvent.VK_ALT, KeyEvent.VK_SHIFT};
Robot shiftkey=null;
Robot altkey=null;
try {
shiftkey = new Robot();
altkey=new Robot();
} catch (AWTException e) {
e.printStackTrace();
}
altkey.keyPress(keyInput[0]);
shiftkey.keyPress(keyInput[1]);
altkey.keyRelease(keyInput[0]);
shiftkey.keyRelease(keyInput[1]);
燒製Alt + LSHIFT組合鍵來實現這一目標（見職位的底部）
這有時有效，有時它沒有觀察到一點不穩定的行爲。有時，即使代碼執行後，它也不會變回English（United States） on FocusLost事件。
我也使用
malyalamField.enableInputMethods(true);
malyalamField.getInputContext().selectInputMethod(new Locale("MY", "IN"));
嘗試，但這個也沒有工作，selectInputMethod()返回NULL
我可能有錯誤的Locale
做了selectInputMethod()作爲現在我所擁有的最棒的是從012開始擊鍵。有沒有辦法實現這個？
