codenameone虛擬鍵盤沒有顯示在Android設備

Question

我試圖顯示一個虛擬鍵盤，當TextField的重點。當我在Android手機上測試它時，它的默認鍵盤正在顯示，而不是自定義鍵盤。

Form testForm = new Form(new BorderLayout()); 
    TextField txt = new TextField(); 

    String[][] arrOfNumbers = new String[][]{{"1","2","3",}, {"4","5","6",}, {"7","8","9",}, {"0", "00", "$OK$"}}; 

    VirtualKeyboard virtualKB = new VirtualKeyboard(); 
    virtualKB.addInputMode("NUM_KB", arrOfNumbers); 
    virtualKB.setInputModeOrder(new String[]{"NUM_KB"}); 
    VirtualKeyboard.bindVirtualKeyboard(txt, virtualKB); 

    testForm.add(BorderLayout.NORTH, txt);   
    testForm.show(); 

Answer 1

虛擬鍵盤類是遺留功能的一部分，不應使用。 Codename One使用本地輸入，您的代碼將使用本地數字輸入：

Form testForm = new Form(new BorderLayout()); 
TextField txt = new TextField(); 
txt.setConstraint(TextField.NUMERIC); 

testForm.add(BorderLayout.NORTH, txt);   
testForm.show();
