Android OnClickListener 仅在第二次点击时触发

Question

My OnClickListener gets only called on the second click. The OnLongClickListener for the same View works as expected. I tried using OnTouchListener instead, but that gets obviously triggered when swiping.

My listeners are abstract methods of an Interface that I implement in my activity:

interface OnVocableFlashcardFragmentInteractionListener {
    fun onEditTextLongClick(view: View): Boolean
    fun onEditTextClick(view: View)
}

I set the listeners of my View like this in my RecyclerViewAdapter Class:

init{
    setHasStableIds(true)

    mEditTextOnClickListener = View.OnClickListener {
        mListener.onEditTextClick(it)
    }

    mEditTextOnLongClickListener = View.OnLongClickListener {
        mListener.onEditTextLongClick(it)
    }
}

override fun onBindViewHolder(holder: FlashcardViewHolder, position: Int) {
    ...
    editText.let { it.tag = it.keyListener; it.keyListener = null; }
    editText.setOnClickListener(mEditTextOnClickListener)
    editText.setOnLongClickListener(mEditTextOnLongClickListener)
    ...
}

The implementation of the listeners in my activity looks like following:

override fun onEditTextClick(view: View) {
    //-- only show toast if view is not editable (becomes editable on LongClick)
    if ((view as EditText).keyListener == null) {
        if (mToast != null) {
            mToast!!.cancel()
        }
        //-- inform user to long press to edit entry
        mToast = Toast.makeText(this, resources.getString(R.string.long_click_to_edit), Toast.LENGTH_LONG)
        mToast!!.show()
    }
}

override fun onEditTextLongClick(view: View): Boolean {
    //-- I saved the KeyListener in the editTexts tag attribute
    //-- to make it clickable again when needed
    (view as EditText).keyListener = view.getTag() as KeyListener
    showSoftKeyboard(view)
    return true
}

The XML of my View looks like following:

            <EditText
            android:id="@+id/et_vocable_word"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="8dp"
            android:background="@null"
            android:textStyle="bold"
            android:hint="@string/enter_word"
            android:imeOptions="actionNext"
            android:inputType="textNoSuggestions"
            android:maxLines="1"
            android:singleLine="true" />

the view's parents and its parents parents are not declared as android:focusable="true" or android:clickable="true"

In my AndroidManifest.xml I have set android:windowSoftInputMode="stateHidden" for my activity to prevent the SoftInput from showing up when the activity starts.

Am I doing something utterly wrong or why does the OnClickListener only get called on the second click? Does anyone have an Idea how I could solve the problem?

Answer 1

you must make edit text focusable attribute false, because its default value is auto and this means is framework determine it must be true and false.when it be true at your first touch it has been focused by keyboard.

Answer 2

I was able to achieve the desired behavior by using OnTouchListener instead of OnClickListener like so:

override fun onEditTextTouch(editText: EditText, event: MotionEvent): Boolean {
    //-- if the pressed gesture has finished
    if (event.action == MotionEvent.ACTION_UP)
    //-- only show toast if view is not editable (becomes editable on LongClick)
        if (editText.keyListener == null) {
            if (mToast != null) {
                mToast!!.cancel()
            }
            //-- inform user to long press to edit entry
            mToast = Toast.makeText(this, resources.getString(R.string.long_click_to_edit), Toast.LENGTH_LONG)
            mToast!!.show()
        }
    return false
}

In my previous attempts at replacing my clickListener with a touchListener I forgot to check for (event.action == MotionEvent.ACTION_UP) so my code was also executed when swiping (which i did not want)
