How to do something after user clicks on my EditText
I have an EditText
that shows time. After user clicks the EditText
I want to show a TimePickerDialog
, so I set a View.OnClickListener
to my EditText
.
But the OnClickListener
is beh开发者_如何转开发aving weirdly - I touch the EditText
and then software keyboard appears (which I don't want). When I touch again, OnClickListener.onClick()
is finally called and the dialog appears.
What should I do if I want the dialog to appear immediately?
Unlike most other controls, EditText
s are focusable while the system is in 'touch mode'. The first click event focuses the control, while the second click event actually fires the OnClickListener
. If you disable touch-mode focus with the android:focusableInTouchMode
View attribute, the OnClickListener
should fire as expected.
<EditText
android:text="@+id/EditText01"
android:id="@+id/EditText01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusableInTouchMode="false" />
Another solution is to use the ontouchlistener
:
edittext.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if(MotionEvent.ACTION_UP == event.getAction()) {
mQuaternion_1.setText("" + mQ1);
}
return true; // return is important...
}
});
If it returns true
the event is handled and keyboard wont popup. If you'd want the keyboard to still popup and register click you'd have it return false
.
It sounds like you don't want the user to actually be able to type in the EditText. You just want them to be able to pick a time via a time picker. So why not just a button that pops up a TimePickerDialog? You could display the time that was picked in a TextView.
Or you could just replace the EditText view with a TimePicker view (not a dialog, just a regular view).
If I understand correctly you just need something like
<EditText android:text="@+id/EditText01" android:id="@+id/EditText01"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:clickable="true" android:inputType="none" />
not editable and clickable. Set the OnClickListener
and you're done.
In theory, in the practice you should add too
android:editable="false"
which is deprecated but does the trick.
I solved this by using a customized Button like this:
<Button
android:id="@+id/btTime"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:text="test"
android:textSize="20dp"
android:background="@android:drawable/edit_text" />
Instead of touch Listener use Text Change Listener:
editText.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
//yourFunction();
}
@Override
public void afterTextChanged(Editable s) {
}
});
