How to do something after user clicks on my EditText

Solution 1:

Unlike most other controls, EditTexts 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" />

Solution 2:

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.

Solution 3:

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).

Solution 4:

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" />

Solution 5:

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) {

        }
    });
