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
}
}
});

Reverse layouts inside RelativeLayout programmatically

I have one relativeLayout and three view's inside RelativeLayout. There views are place on each other.
<RelativeLayout
android:id="#+id/includelayoutgroup"
android:layout_width="match_parent"
android:layout_height="match_parent">
<View xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/transparentColorView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:clickable="true"
android:visibility="visible" />
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/keyboard_main_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:visibility="visible">
<include
layout="#layout/transfer_keyboard_fragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/finalRequestView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:clickable="true"
android:visibility="visible">
<include
layout="#layout/fragment_transfer_new_version_container_child"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
</RelativeLayout>
Is it a possible to reverse position my view's? I mean,in my code last Layout is finalRequestView and in button click i would to my last view in first position,and other view's place on my view,
How i can solve this problem?

I try to reverse layout by following demo & it works as you want, please take a look
ReverseLayout.java
public class ReverseLayout extends AppCompatActivity {
LinearLayout llRoot;
Button btReverseLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.reverse_layout);
llRoot = (LinearLayout) findViewById(R.id.llRoot);
btReverseLayout = (Button) findViewById(R.id.btReverseLayout);
btReverseLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ArrayList<View> alViews = new ArrayList<View>();
for (int i = llRoot.getChildCount() - 1; i >= 0; i--) {
View view = llRoot.getChildAt(i);
llRoot.removeViewAt(i);
alViews.add(view);
}
for (int j = 0; j < alViews.size(); j++) {
llRoot.addView(alViews.get(j));
}
}
});
}
}

Listview setOnItemClickListener won't trigger

I am trying to change programmatically the background color of ListView item when the user tap on it. I am trying to implement a solution using setOnItemClickListener, but I have trouble making the listener work. Here is my code:
ArrayList<Integer> menuIcons = app.Theme.Icons.getMenuPanelIconList();
ArrayList<String> menuText = app.Languages.Active.getMenuPanelItemNames();
listview_menu = (ListView) findViewById(R.id.listview_menu);
listview_menu.setBackgroundColor(Color.parseColor("#" + app.Theme.ThemeBackColor));
MenuPanelListViewAdapter menuPanelListViewAdapter = new MenuPanelListViewAdapter(ActivityMain.this, menuIcons, menuText);
listview_menu.setAdapter(menuPanelListViewAdapter);
listview_menu.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adpterView, View view, int position,
long id) {
for (int i = 0; i < listview_menu.getChildCount(); i++) {
if(position == i ){
listview_menu.getChildAt(i).setBackgroundColor(Color.BLUE);
}else{
listview_menu.getChildAt(i).setBackgroundColor(Color.TRANSPARENT);
}
}
}
});

First change background of all item to transperent then set clicked view's background to your desired color like below.
MenuPanelListViewAdapter menuPanelListViewAdapter = new MenuPanelListViewAdapter(ActivityMain.this, menuIcons, menuText);
listview_menu.setAdapter(menuPanelListViewAdapter);
listview_menu.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adpterView, View view, int position,
long id) {
for (int i = 0; i < listview_menu.getChildCount(); i++) {
listview_menu.getChildAt(i).setBackgroundColor(Color.TRANSPARENT);
}
view.setBackgroundColor(Color.BLUE);
menuPanelListViewAdapter.notifyDataSetChanged(); // this is importent
}
});
