How will search suggestion overlap in map view

How will search suggestion overlap in map view - android

I have search view that looks like below which doesn't overlap the search suggestion. Like:
What I currently Have
However, I want the search suggestion overlap above the map.
Like:
Here's what I w ant to achieve
Code:
searchView = (MaterialSearchView) findViewById(R.id.search_view);
searchView.setOnQueryTextListener(new MaterialSearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
//Do some magic
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
searchView.setSuggestions(getResources().getStringArray(R.array.query_suggestions));
return false;
}
});
searchView.setOnSearchViewListener(new MaterialSearchView.SearchViewListener() {
#Override
public void onSearchViewShown() {
//Do some magic
}
#Override
public void onSearchViewClosed() {
//Do some magic
}
});
Here is the XML. I have no clue if the problem is here for any solution
<FrameLayout
android:id="#+id/toolbar_container"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/colorPrimary" />
<com.miguelcatalan.materialsearchview.MaterialSearchView
android:id="#+id/search_view"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</FrameLayout>
Also, is there a way for me to attach the search suggestion to
ArrayList<HashMap<String, String>> vehicle;

my problem is that my RecyclerView view doesn't scroll properly. I have 20 items but it shows 9 elements on the first screen and I can just scroll 1 item and not anymore. I can just get to 10th element.
I'm new using RecyclerView in CoordinatorLayout, and none of the tutorials I saw helped me solve my problem.
can anyone show me how to solve this problem or show me an example to handle a RecyclerView in a CoordinatorLayout?
my recyclerview item:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?android:attr/selectableItemBackground"
android:clickable="true"
android:focusable="true"
android:orientation="vertical"
android:paddingBottom="#dimen/row_padding_vertical"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/row_padding_vertical">
<TextView
android:id="#+id/controller_title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:textColor="#color/pureBlack"
android:textSize="16sp"
android:textStyle="bold" />
<TextView
android:id="#+id/controller_id"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="#color/pureBlack"
android:layout_below="#id/controller_title" />
my Adapter:
public class ControllerPickerAdapter extends RecyclerView.Adapter<ControllerPickerAdapter.MyViewHolder> {
private List<Controller> controllerList;
public static class MyViewHolder extends RecyclerView.ViewHolder {
public TextView title,id;
public MyViewHolder(View v) {
super(v);
title = v.findViewById(R.id.controller_title);
id = v.findViewById(R.id.controller_id);
}
}
public ControllerPickerAdapter(List<Controller> controllerList) {
this.controllerList = controllerList;
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.controller_list_row, parent, false);
MyViewHolder vh = new MyViewHolder(v);
return vh;
}
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
Controller controller = controllerList.get(position);
holder.title.setText(controller.getTitle());
holder.id.setText("" + controller.getId());
}
#Override
public int getItemCount() {
return controllerList.size();
}
}

You have not added scroll flags to your RecyclerView. Try adding it using below code, use scroll value that suits your requirement.
app:layout_scrollFlags="scroll|enterAlways"

Why u put RecyclerView inside AppBarLayout? is it necessary? if not, then use this one:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="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:background="#color/pureWhite"
tools:context=".ControllerPickerActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#00cc3d"
app:layout_scrollFlags="scroll|enterAlways" />
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/controllers_picker_recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?attr/actionBarSize"
android:background="#color/pureWhite" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
app:srcCompat="#drawable/ic_plus_30dp" />
</android.support.design.widget.CoordinatorLayout>
or u can try this one:
<?xml version="1.0" encoding="utf-8"?>

Moving A Button in CollapsingToolbarLayout

I'm trying to make toolbar button to stay at the bottom when collapsingToolbarLayout is expanded and moves up and get pinned when the collapsingToolbarLayout is collapsed. The way it behave now is always pinned on top. Here is what I have:

/>
</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
The toggle button always stays on top place, I want it to behave similar to WhatsApp edit button in group detail when it moves up and down as you expand the toolbar layout.

Solved it by taking the button out of the toolbar and putting it a child of the CollapsingToolbarLayout with margin bottom and collapsing mode as pin

For complex behaviors you need to code this in behavior classes
Step # 1:
Create a Custom Behavior
public class BottomBarBehavior extends CoordinatorLayout.Behavior<LinearLayout> {
private int defaultDependencyTop = -1;
public BottomBarBehavior(Context context, AttributeSet attrs) {
super(context, attrs);
}
public BottomBarBehavior() {
}
#Override
public boolean layoutDependsOn(CoordinatorLayout parent, LinearLayout child, View dependency) {
return dependency instanceof AppBarLayout;
}
#Override
public boolean onDependentViewChanged(CoordinatorLayout parent, LinearLayout child, View dependency) {
//do something with the layout. see commented
return true;
}
}
Step # 2
Assign the behavior to the toolbar.
Either via xml:
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:gravity="center"
**app:layout_behavior=".BottomBarBehavior"**
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<Button
android:id="#+id/mmv_toggle_detail"
android:layout_width="60dp"
android:layout_height="60dp"
android:layout_gravity="right"
/>
</android.support.v7.widget.Toolbar>

Try this, I hope it will help you ...
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/col"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/colorPrimaryDark"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:elevation="4dp"
android:transitionName="#string/pic_transition_name"
app:layout_collapseMode="parallax">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/clpsToolbarLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:collapsedTitleTextAppearance="#style/CollapsedText"
app:contentScrim="#color/colorPrimary"
app:expandedTitleTextAppearance="#style/ExpandedText"
app:layout_scrollFlags="scroll|exitUntilCollapsed|snap"
>
<ImageView
android:id="#+id/iv_gallery"
android:layout_width="match_parent"
android:layout_height="320dp"
android:layout_gravity="center_horizontal"
app:layout_collapseMode="parallax"
/>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:gravity="center"
app:layout_collapseMode="pin"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<Button
android:id="#+id/mmv_toggle_detail"
android:layout_width="60dp"
android:layout_height="60dp"
android:layout_gravity="center|bottom"
app:layout_anchor="#id/appbar"
app:layout_anchorGravity="bottom|center" />
</android.support.design.widget.CoordinatorLayout>
in JavaClass you will add below code .
appBarLayout.addOnOffsetChangedListener(new AppBarLayout.OnOffsetChangedListener() {
#Override
public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
if (Math.abs(verticalOffset) == appBarLayout.getTotalScrollRange()) {
// Collapsed
} else if (verticalOffset == 0) {
// Expanded
if (yourBtn.getVisibility()==View.VISIBLE) {
yourBtn.setVisibility(View.INVISIBLE);
}
} else {
// Somewhere in between
if (yourBtn.getVisibility()==View.VISIBLE) {
yourBtn.setVisibility(View.INVISIBLE);
}
}
}
});

Recycler inside bottom tablyout not showing last row

I have a coordinate layout inside which there is custom ViewPager and bottom TabLayout. Now issue is RecyclerView of one of fragment of ViewPager not scrolling properly. Its hiding the last row.
tablayout.xml
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<CustomViewPager
android:id="#+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"
style="#style/AppTabLayout"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_gravity="bottom"
android:layout_alignParentBottom="true"
android:background="#color/colorBottomBar"
/>
</RelativeLayout>
</android.support.design.widget.CoordinatorLayout>
CustomViewPager
public class CustomViewPager extends ViewPager {
private boolean enabled;
public CustomViewPager(Context context, AttributeSet attrs) {
super(context, attrs);
this.enabled = true;
}
#Override
public boolean onTouchEvent(MotionEvent event) {
if (enabled)
return super.onTouchEvent(event);
else
return false;
}
#Override
public boolean onInterceptTouchEvent(MotionEvent event) {
return enabled && super.onInterceptTouchEvent(event);
}
public void setPagingEnabled(boolean enabled) {
this.enabled = enabled;
}
public boolean isPagingEnabled() {
return enabled;
}
}
ViewPager Fragmet having recyclerview
<RelativeLayout
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="80dp"
android:background="#color/toolbarColor"
android:id="#+id/tool_bar"
android:theme="#style/ThemeOverlay.AppCompat.Dark">
<ImageView
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_marginLeft="30dp"
android:layout_marginStart="30dp"
android:id="#+id/reload"
android:clickable="true"
android:src="#drawable/icon_refresh"/>
</android.support.v7.widget.Toolbar>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="55dp"
android:layout_below="#+id/tool_bar"
android:orientation="horizontal"
android:id="#+id/sort_layout"
android:background="#android:color/white"
android:weightSum="1">
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/recyclerview"
android:scrollbars="vertical"
android:background="#color/colorBottomBar"
android:layout_below="#+id/sort_layout"/>
</RelativeLayout>
In above picture , you see that last row of RecyclerView is not completely visible.

Put custom pager and tab layout in relative layout and set custom pager above tab layout like this
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<CustomViewPager
android:id="#+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/#+id/tab_layout
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"
style="#style/AppTabLayout"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_gravity="bottom"
android:layout_alignParentBottom="true"
android:background="#color/colorBottomBar"
/>
</RelativeLayout>
</android.support.design.widget.CoordinatorLayout>

In your ‍tablayout.xml use this code instead of yours:
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<CustomViewPager
android:id="#+id/view_pager"
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"
style="#style/AppTabLayout"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_gravity="bottom"
android:layout_alignParentBottom="true"
android:background="#color/colorBottomBar"/>
</RelativeLayout>
</android.support.design.widget.CoordinatorLayout>
