Below is the code to handle the correct behaviour of my actionBar/toolbar/tabBar and below them the nestedScrollView with a ViewPager(webView). The ViewPager is basically a normal webView.
I am seeking to copy this exact behavior:
Everything works except my ViewPager can't be scrolled vertically at the same time as the toolBar being scrolled. When the viewPager is being scrolled the toolbar is static (in order to make the toolbar scroll aswell I need to manually scroll the toolbar-area but it does not get affected by the viewPager at all). I am not able to scroll both at the same time like the example above!
My code:
<?xml version="1.0" encoding="utf-8"?>

In order to make my viewPager(webView) scrollable I added a new class which extends webView:
public class TouchyWebView extends WebView {
public TouchyWebView(Context context) {
super(context);
}
public TouchyWebView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public TouchyWebView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
public boolean onTouchEvent(MotionEvent event){
requestDisallowInterceptTouchEvent(true);
return super.onTouchEvent(event);
}
}

Please help!
Put your ScrollView inside DrawerLayout like below code. just copy and paste it.

I looked at the official tutorial but I just don't get it.
This is my class:
public class mycontrol extends GridLayout {
public mycontrol(Context context, AttributeSet attrs) {
super(context, attrs);
}}
This is my res/layout/mycontrol.xml:
<GridLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="60dp"
android:columnCount="4"
android:rowCount="2"
android:background="#drawable/cellshapeownstatus"
android:paddingTop="5dp"
android:id="#+id/my_status_id">
<TextView
android:textColor="#FFFFFF"
android:layout_column="1"
android:layout_row="0"
android:layout_marginLeft="10dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="doing stuff"
android:id="#+id/myOwnName" /></GridLayout>
This is my res/layout/activity_main.xml, where I want to show mycontrol:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="2dp"
android:paddingRight="2dp"
tools:context=".MainActivity"
android:orientation="vertical"
android:background="#0A3E61"
android:id="#+id/activity_main_id">
<com.example.test.mycontrol
android:id="#+id/my_status"
android:layout_width="fill_parent"
android:layout_height="70dp"/></LinearLayout>
Nothing shows up in the Designer Preview. I can build without errors, but it instantly crashes when I try to run it on my Phone.
Simply use 'include'
<include
android:layout_width="fill_parent"
android:layout_height="wrap_content"
layout="#layout/mycontrol"
/>
You don't need to extend GridLayout and you forgot to inflate your xml:
public class MyControl extends FrameLayout {
public MyControl(Context context, AttributeSet attrs) {
super(context, attrs);
inflate(context, R.layout.mycontrol, this);
}
}
layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="2dp"
android:paddingRight="2dp"
tools:context=".MainActivity"
android:orientation="vertical"
android:background="#0A3E61"
android:id="#+id/activity_main_id">
<com.example.test.MyControl
android:id="#+id/my_status"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
I have the sequent layout:
<com.example.CustomSwipeRefreshLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/include" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerHorizontal="true"
android:gravity="center_horizontal"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/header_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" />
<ListView
android:id="#+id/lv"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
</LinearLayout>
</LinearLayout>
</com.example.CustomSwipeRefreshLayout>
with fixed header and a scrollable list. CustmoSwipeRefreshLayout is a class that extends SwipeRefreshLayout:
public class CustomSwipeRefreshLayout extends SwipeRefreshLayout {
private ListView childListView;
public CustomSwipeRefreshLayout(Context context) {
super(context);
}
public CustomSwipeRefreshLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public void setChildListView(ListView childListView) {
this.childListView = childListView;
}
#Override
public boolean canChildScrollUp() {
return childListView.getFirstVisiblePosition() != 0;
}
(where childListView is the widget with id lv). This code doesn't work as i want. In fact, progress circle appear in two cases:
- i swipe listview to top
- i make swipe gesture on header and listview has first element visible.
I would that progress circle appear both if i swipe listview to top (as works now), and also if i make swipe gesture on header and listview is not to top element
I had the same problem, my solution was set android:clickable="true" inside my parent layout. try it like this:
<com.example.CustomSwipeRefreshLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/include" >
<LinearLayout
android:clickable="true" <!-- this line -->
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerHorizontal="true"
android:gravity="center_horizontal"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/header_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" />
<ListView
android:id="#+id/lv"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
</LinearLayout>
</LinearLayout>
</com.example.CustomSwipeRefreshLayout>
I have nested calendarview in ScrollView . My problem begins when height of view increases.
I can scroll calendar months vertically but when scrollview scrollbar comes it does not let scroll calendar. Instead of scrolling calendar the whole view scroll up or down.

I've found answer to this problem here:
https://stackoverflow.com/a/9687545
Basically you need to implement custom CalendarView and override onInterceptTouchEvent method.
I did it as following:
package com.example.app.views;
public class CalendarViewScrollable extends CalendarView {
public CalendarViewScrollable(Context context) {
super(context);
}
public CalendarViewScrollable(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CalendarViewScrollable(Context context, AttributeSet attrs,
int defStyle) {
super(context, attrs, defStyle);
}
#Override
public boolean onInterceptTouchEvent(MotionEvent ev)
{
if (ev.getActionMasked() == MotionEvent.ACTION_DOWN)
{
ViewParent p = getParent();
if (p != null)
p.requestDisallowInterceptTouchEvent(true);
}
return false;
}
}
Then just use this view in XML layout file:
<com.example.app.views.CalendarViewScrollable
android:id="#+id/datePicker1"
android:layout_width="400dp"
android:layout_height="400dp"
/>
Here's one solution, you can implement a custom ScrollView which will only intercept verticale swipe.
#Override
public boolean onInterceptTouchEvent(MotionEvent ev) {...}
"onInterceptTouchEvent" will return false for horizontal swipe, so horizontal swipe will be enable for the CalendarView.
You can read more about this heree : https://stackoverflow.com/a/2655740/5158173
