Android, setNextFocusDownId not working as expected

I have a layout that as inside of it a LinearLayout that will receive a bunch of dynamic EditText, but the problem is that the AutoCompleteTextView next button doesn't go to the next EditText that is inside of the LinearLayout.
This is the XML
<TabHost
android:id="#+id/DocumentTabHost"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_marginBottom="4dp"
android:layout_marginTop="2dp"
app:layout_constraintBottom_toTopOf="#+id/DocumentBTNFinalize"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TabWidget
android:id="#android:id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/DocumentTab1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<TextView
android:id="#+id/textView4"
android:layout_width="203dp"
android:layout_height="wrap_content"
android:layout_marginLeft="15dp"
android:layout_weight="1"
android:text="#string/general_indentify" />

<ImageButton

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_alignParentTop="true"
android:layout_marginTop="15dp"
app:srcCompat="?android:attr/actionModeWebSearchDrawable" />
<LinearLayout
android:id="#+id/DocumentTab1DynamicLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="55dp"
android:orientation="vertical">
</LinearLayout>
</RelativeLayout>
</LinearLayout>
<LinearLayout
android:id="#+id/DocumentTab2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<RelativeLayout
android:id="#+id/DocumentTab2Relative"
android:layout_width="match_parent"
android:layout_height="match_parent">
</RelativeLayout>
</LinearLayout>
</FrameLayout>
</LinearLayout>
</TabHost>
And this is the part of the code that I have the focus for the EditText
tempText = new DocEditText(Documents.this);
if (firstButton)
{
_autoComplete.setNextFocusDownId(tempText.getId());
firstButton = false;
}
if (TextUtils.equals(GlobalVars.GeneralConfig.get("editTextType"), "1"))
{
tempText.setRawInputType(Configuration.KEYBOARD_QWERTY);
}
tempText.setSingleLine();
tempText.setSQLCampName(idCampo[1]);
tempText.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));
tempText.setTypeOfEditText(1);
_cabEditText.add(tempText);
tempLayout.addView(tempText);
The _autocomplete is my AutoCompleteTextView and by setting the setNextFocusDownId(tempText.getId()); should not work ? So when I press next on the soft keyboard to go to it?

Well after some time I did pick on this part of the code and was searching and found another solution for this in StackOverFlow link
Here is the solution for it
if (firstButton)
{
_autoComplete.setOnEditorActionListener(new TextView.OnEditorActionListener()
{
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event)
{
if (actionId == EditorInfo.IME_ACTION_DONE || actionId == EditorInfo.IME_ACTION_NEXT)
{
tempText.requestFocus();
}
return false;
}
});
firstButton = false;
}
So basicly when the enter or next button is pressed on the keyboard it will request focus for the next EditText/AutoCompleteTextView that was created dynamicly

Button does not get clicked on the first attempt

There are a few buttons in my activity which do not get clicked on the first attempt but they get clicked from the second time onwards. It seems that the button gets focus on the first click and gets actually pressed from the second time onwards. What can be the reason that these buttons do not get clicked the first time?
I have noticed that this behaviour is only shown by buttons that are at the very bottom of my activity.

This issue is actually a bug in the NestedScrollView class for a while now.
I solved this issue my making some tweaks to the source code of the NestedScrollView class, as follows :-
public class NestedScrollView extends FrameLayout implements NestedScrollingParent,
NestedScrollingChild, ScrollingView {
...
#Override
public boolean onTouchEvent(MotionEvent ev) {
switch (actionMasked) {
case MotionEvent.ACTION_DOWN: {
if (getChildCount() == 0) {
return false;
}
//add this condition
if (!inChild((int) ev.getX(), (int) ev.getY())) {
return false;
}
if ((mIsBeingDragged = !mScroller.isFinished())) {
final ViewParent parent = getParent();
if (parent != null) {
parent.requestDisallowInterceptTouchEvent(true);
}
}
...
}
}
#Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
...
switch (action & MotionEventCompat.ACTION_MASK) {
...
case MotionEvent.ACTION_DOWN: {
...
// replace this line:
// mIsBeingDragged = !mScroller.isFinished();
mIsBeingDragged = false;
...
}
}
}
}
After doing this it should work fine.

How to hide widget when keyboard pops?

I have two ViewPager on the same view with weight= 70/30 . The problem is when the keyboard pops, my both view keep the same weight and do not display my EditText.

I think my last solution is to make disappear my picker at the top when my keyboard pops. How can I do this?

Hope this help you :
public class YourActivity extends BaseActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_activity);
attachKeyboardListeners();
}
#Override
protected void onShowKeyboard(int keyboardHeight) {
// when keyboard is shown
yourWidget.setVisibility(View.GONE);
}
#Override
protected void onHideKeyboard() {
// when keyboard is hidden
yourWidget.setVisibility(View.VISIBLE);
}
}

Try to use ScrollView in parent view, for example-
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:fab="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusableInTouchMode="true">
<ScrollView
android:id="#+id/scroll_view_parent"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:fillViewport="true"
android:scrollbars="none">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
..................................
type your code here
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/colorWhite"
android:orientation="vertical">
..................................
type your code here
</LinearLayout>
</LinearLayout>
</ScrollView>
</RelativeLayout>

You can set listeners when keyboard is opened and closed.
// ContentView is the root view of the layout of this activity/fragment
contentView.getViewTreeObserver().addOnGlobalLayoutListener(
new ViewTreeObserver.OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
Rect r = new Rect();
contentView.getWindowVisibleDisplayFrame(r);
int screenHeight = contentView.getRootView().getHeight();
// r.bottom is the position above soft keypad or device button.
// if keypad is shown, the r.bottom is smaller than that before.
int keypadHeight = screenHeight - r.bottom;
Log.d(TAG, "keypadHeight = " + keypadHeight);
if (keypadHeight > screenHeight * 0.15) { // 0.15 ratio is perhaps enough to determine keypad height.
// keyboard is opened
} else {
// keyboard is closed
}
}
});

Hide RelativeLayout when pull ScrollView

I have RelativeLayoutin top Scroll View, and now i want when pull down RelativeLayoutin hint and pull up RelativeLayoutin show.
How i do?
My xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
tools:context="${relativePackage}.${activityClass}" >
<RelativeLayout
android:id="#+id/Rlayout_top"
android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_marginBottom="5dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:layout_marginTop="5dp" />
</RelativeLayout>
<ScrollView
android:id="#+id/Scrollview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/Rlayout_top"
android:paddingBottom="20dp" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
</RelativeLayout>
Thank you!

try this :
private float lastPosition=0;
scrollView.getViewTreeObserver().addOnScrollChangedListener(new OnScrollChangedListener() {
#Override
public void onScrollChanged() {
int scrollY = rootScrollView.getScrollY(); //for verticalScrollView
if(scrollY >lastPosition){
// hide your RelativeLayout
}else {
//show your view
}
lastPosition=scrollY
});

How to disable Scrollview

<adapters.CustomViewPager
android:layout_width="match_parent"
android:layout_height="wrap_content"

</ScrollView>

I used this and it worked for me :
// Get the ScrollView
final ScrollView myScroll = (ScrollView) findViewById(R.id.display_scrollview);
// Disable Scrolling by setting up an OnTouchListener to do nothing
myScroll.setOnTouchListener( new OnTouchListener(){
#Override
public boolean onTouch(View v, MotionEvent event) {
return true;
}
});
// Enable Scrolling by removing the OnTouchListner
tvDisplayScroll.setOnTouchListener(null);
happy programming......!!!
