我已經在片段中實現了我自己的自定義鍵盤。當我點擊editText時，鍵盤會打開。但是所有的數字鍵都不起作用，有些鍵如7,0和8可以點擊，但大多數情況下不能。像回車鍵，右和左都正常工作。在Activity中相同的代碼工作得非常好，但在Fragment中實現時卻不起作用。並且onFocus Listerner在這個片段中沒有被調用。什麼是理由？我實現的代碼如下：自定義鍵盤不能在片段中工作
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_barcode_detail,
container, false);
editText_barcode = (EditText) rootView
.findViewById(R.id.editText_barcode);
// Lookup the KeyboardView
mKeyboardViewNum = (KeyboardView)
rootView.findViewById(R.id.numerickeyboardview);
mKeyboardView = (KeyboardView) rootView.findViewById(R.id.keyboardview);
// Numeric Keyboard
key = new NumericKeyboard();
mKeyboardNum = new Keyboard(mActivity,
R.xml.numeric_keyboard);
// Lookup the KeyboardView
// Attach the keyboard to the view
mKeyboardViewNum.setKeyboard(mKeyboardNum);
listKeysNum = mKeyboardNum.getKeys();
// Do not show the preview balloons
mKeyboardView.setPreviewEnabled(true);
// Install the key handler
mKeyboardViewNum
.setOnKeyboardActionListener(key.mOnKeyboardActionListenerNum);
// Numeric Keyboard
editText_barcode.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
editos = (EditText) v;
System.out.println("====onc== "+editos);
hideCustomKeyboard();
key.showCustomNumKeyboard(v);
}
});
editText_barcode.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
EditText edittext = (EditText) v;
int inType = edittext.getInputType(); // Backup the input type
edittext.setInputType(InputType.TYPE_NULL); // Disable standard keyboard
edittext.onTouchEvent(event); // Call native handler
edittext.setInputType(inType); // Restore input type
edittext.setTextIsSelectable(true);
return false;
}
});
editText_barcode.setOnFocusChangeListener(new OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
editos = (EditText) v;
System.out.println("====onf== "+editos);
key.showCustomNumKeyboard(v);
} else {
key.hideCustomNumKeyboard();
}
}
});
return rootView;
}
private OnKeyboardActionListener mOnKeyboardActionListenerNum = new
OnKeyboardActionListener() {
@Override
public void onKey(int primaryCode, int[] keyCodes) {
// Here check the primaryCode to see which key is pressed
// based on the android:codes property
int start = editos.getSelectionStart();
Editable editable = editos.getText();
switch (primaryCode) {
case 0:
editable.insert(start, "0");
System.out.println("=====0== "+editable);
