I have implemented my own custom keyboard in a fragment. The keyboard opens when i click the editText. But all the number keys are not working, some keys like 7, 0 and 8 works onclicking but most of the time it doesn't. keys like enter, right and left are working correctly. The same code works absolutely fine in Activity but its not working when implemented in Fragment. And also onFocus Listerner is not being called in this fragment. What would be reason? The code I implemented is as follows:
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);
break;
case 1:
editable.insert(start, "1");
break;
case 2:
editable.insert(start, "2");
break;
case 3:
editable.insert(start, "3");
break;
case 4:
editable.insert(start, "4");
break;
case 5:
editable.insert(start, "5");
break;
case 6:
editable.insert(start, "6");
break;
case 7:
editable.insert(start, "7");
break;
case 8:
editable.insert(start, "8");
break;
case 9:
editable.insert(start, "9");
break;
case 10:
if (!editos.getText().toString().contains(".")) {
editable.insert(start, ".");
}
break;
case -1:
if (editable != null && start > 0) {
editable.delete(start - 1, start);
}
break;
case 100:
if (editos == editText_barcode) {
hideCustomNumKeyboard();
}
break;
case 101:
if (start > 0)
editos.setSelection(start - 1);
break;
case 201:
if (start < editos.length())
editos.setSelection(start + 1);
break;
}
}
@Override
public void onPress(int arg0) {
}
@Override
public void onRelease(int primaryCode) {
}
@Override
public void onText(CharSequence text) {
}
@Override
public void swipeDown() {
}
@Override
public void swipeLeft() {
}
@Override
public void swipeRight() {
}
@Override
public void swipeUp() {
}
};
and XML is:

Posting as an answer since I don't have the reputation to comment...
Check out the following documentation link. https://developer.android.com/reference/android/R.attr.html#keycode
The primaryCode parameter you are using as your switch input should be using these codes. (KeyEvent.KEYCODE_[0-9] correspond to 7-16)
Can you post your XML file please? My assumption is that your android:codes for each Key in there are corresponding to the KEYCODE_[0-9] for those.
If this is a correct assumption then your switch case 7 will be triggered by pressing key 0, case 8 by key 1, etc.
