I have an application with a numpad (keys 0-9, Ok and Delete) that is always visible on screen.
When the user sets the focus on an EditText that has an numeric input method, then the key pressed on the numpad should be applied to the focused EditText .
My current approach is to set a OnFocusChanged listener on each EditText with numeric input method, and then remember the focused control:
EditText txt1 = (EditText) findViewById(R.id.editText1);
txt1.setOnFocusChangeListener(new View.OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if(hasFocus)
focused = (EditText)v; // focused is a member of the Activity class
}});
Then when a numpad key is pressed the key is applied to the focused control.
To me this seems a bit complex, is there an easier way that works automagically (without the focus change listener) on all EditText widgets with numeric input method?
Secondly, is there a way to disable the soft keyboard for those EditText widgets with numeric input only?
I think you can use onKeyDown() for your EditText (let's call it numberBox).
ReplyDeleteThe logic is this:
let's say you have all your digit buttons in a collection:
private ImageButton []digitButtons = new ImageButton[10];
than you set the onClickListeners for each button:
private void setClickListenersForDigitButtons() {
for(int i=0; i < digitButtons.length; i++) {
int resId = getResources().getIdentifier(getPackageName()+":id/btn_digit_"+i, null, null);
digitButtons[i] = (ImageButton)findViewById(resId);
final int keyCode = KeyEvent.KEYCODE_0 + i;
digitButtons[i].setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
keyPressed(keyCode);
}
});
}
}
And in the keyPressed method:
private void keyPressed(int keyCode) {
KeyEvent event = new KeyEvent(KeyEvent.ACTION_DOWN, keyCode);
numberBox.onKeyDown(keyCode, event);
}
