I am new to Android and working through a to do list example from a book. I have one Activity which is displaying an EditText and a ListView beneath it. There is an onKey ev
Instead of setOnKeyListener
, try to implement setOnEditorActionListener
. Hope this helps.
Following code solved such problem: You just need to need to add addTextChangedListener like this.Rest is self- explanatory
editabltText.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
@Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
@Override
public void afterTextChanged(Editable editable)
{
}
});
<EditText
android:id="@+id/search"
android:singleLine="true"
android:imeOptions="actionSearch">
try to add singleLine and imeOption attributes.
I was able to get that same example to work by adding the following attribute to the EditText element android:inputType="text"
. This changed the software keyboard that came up for the user and included a Send button.
In the setOnKeyListener code, I changed it to the following:
myEditText.setOnKeyListener(new OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_UP)
if (keyCode == KeyEvent.KEYCODE_ENTER)
{
todoItems.add(0, myEditText.getText().toString());
aa.notifyDataSetChanged();
myEditText.setText("");
return true;
}
return false;
}
});
Don't use KEYCODE_DPAD_CENTER as that's a hardware button for devices that had up, down, left, right arrows.
You could try using a OnEditorActionListener instead:
http://developer.android.com/reference/android/widget/TextView.html#setOnEditorActionListener(android.widget.TextView.OnEditorActionListener)
You could set on the edittext in XML:
android:imeOptions="actionDone"
and then in code:
myEditText.setOnEditorActionListener(new EditText.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_DONE) {
// your action here
return true;
}
return false;
}
)};
Are you using the virtual keyboard? In that case the problem is that an OnKeyListener only gets called by hardware buttons. Take a look here: http://developer.android.com/reference/android/view/View.OnKeyListener.html
The first line says: Interface definition for a callback to be invoked when a hardware key event is dispatched to this view.
Perpaps something line this will solve your problem: Validating edittext in Android
