Recycler inside bottom tablyout not showing last row

Recycler inside bottom tablyout not showing last row - android

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_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">
<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;
}
}

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>

over here i have may adapter
public class MyFragmentAdapter extends FragmentPagerAdapter {
private Context context;
public MyFragmentAdapter(FragmentManager fm, Context context) {
super(fm);
this.context = context;
}
#Override
public Fragment getItem(int position) {
if (position == 0)
return CategoryFragment.getInstance();
else if (position == 1)
return TrendingFragment.getInstance();
else if (position == 2)
return RecentsFragment.getInstance(context);
else
return null;
}
#Override

return 3;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "Category";
case 1:
return "Trending";
case 2:
return "Recents";
}
return "";
}}
this is activity code i used
viewPager = (ViewPager)findViewById(R.id.viewPager);
MyFragmentAdapter adapter = new
MyFragmentAdapter(getSupportFragmentManager(), this);
viewPager.setAdapter(adapter);
tabLayout = (TabLayout) findViewById(R.id.tabLayout);
tabLayout.setupWithViewPager(viewPager);
this is the screenshot
as you can see i am unable to see tab layout in my phone can any help what is the problem
my layout uses bottom navigation behavior
so coordinate layout is necessary and bottom navigation need to be out has it should be child of coordinator layout
I figured out tab layout is hidden behind the app bar

Fragment's RelativeLayout -> under AppBar in Activity (Fragment overlays Toolbars)

I am struggling with this problem.
I have Activity with toolbars (2 and 1 TAB). But after creating Fragment with RecyclerView, this RecyclerView just ignores Toolbars and is all over screen (fullscreen / in front).

You can change activity_main.xml to this.
<android.support.design.widget.CoordinatorLayout

xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"

<FrameLayout
android:id="#+id/frame_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/tabs"
android:visibility="gone"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"

You can add ViewPager and FloatingActionButton to CoordinatorLayout.
And you can add some app:layout_behavior to it.

Collapsible Toolbar - Make Fragment Footer Always Visible in Android

I am making an app that has a ProfilePage with three fragments - About | Posts | Gallery, and I am using a collapsible toolbar with user's image. My second and third fragment will have a footer that should always be visible, but this is what I get:
When my image is expanded the footer disappears. What I want is for my two fragments to have these footers always visible and not depending on toolbar being collapsed or not. My gallery footer should be similar to post footer.

Add following code in your Tab activity:
TabLayout tabLayout;
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);//add your viewpager to TabLayout
tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
LinearLayout l=(LinearLayout) findViewById(R.id.tab123);
final EditText text=(EditText) findViewById(R.id.inputMsg);
Button send=(Button) findViewById(R.id.btnSend);
if (tab.getPosition() == 0) {
l.setVisibility(View.GONE);
System.out.println("About tab");
} else if (tab.getPosition() == 1) {
l.setVisibility(View.VISIBLE);
System.out.println("Posts tab");
send.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String msg = null;
msg = text.getText().toString(); //get input
// Perform your desired task.
}
});
} else if (tab.getPosition() == 2) {
l.setVisibility(View.VISIBLE);
System.out.println("Gallery tab");
send.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String msg = null;
msg = text.getText().toString(); //get input

}
});
}
}
#Override

}
});

Using a coordinatorlayout to collapse a full screen imageview and replace it with viewpager with headers

I started playing around with coordinatoralyout and I'm trying to achieve the behavior on the attached image, I want a background image to be on full screen size and upon a scroll I want some textviews to dissapear and some to stick as parts of a viewpager (rather then a toolbarlayout) any guidance on how can I achieve this?

You can use layout_behavior to handle the strings which you want to be disappear upon scroll. Customise your view behaviour using CoordinatorLayout.Behavior
ViewBehavior.java
public class ViewBehavior extends CoordinatorLayout.Behavior<RelativeLayout> {
private Context mContext;
public ViewBehavior(Context context, AttributeSet attrs) {
mContext = context;
}
#Override
public boolean layoutDependsOn(CoordinatorLayout parent, RelativeLayout child, View dependency) {
return dependency instanceof AppBarLayout;
}
#Override
public boolean onDependentViewChanged(CoordinatorLayout parent, RelativeLayout child, View dependency) {
child.measure(View.MeasureSpec.makeMeasureSpec(parent.getWidth(), View.MeasureSpec.EXACTLY), View.MeasureSpec.makeMeasureSpec(parent.getHeight(), View.MeasureSpec.AT_MOST));
int maxScroll = ((AppBarLayout) dependency).getTotalScrollRange();
float percentage = Math.abs(dependency.getY()) / (float) maxScroll;
float childPosition = dependency.getHeight()
+ dependency.getY()
- child.getMeasuredHeight()
- (getToolbarHeight() - child.getMeasuredHeight()) * percentage / 2;
CoordinatorLayout.LayoutParams lp = (CoordinatorLayout.LayoutParams) child.getLayoutParams();
child.setLayoutParams(lp);
child.setY(childPosition);
return true;
}
public int getToolbarHeight() {
int result = 0;
TypedValue tv = new TypedValue();
if (mContext.getTheme().resolveAttribute(android.R.attr.actionBarSize, tv, true)) {
result = TypedValue.complexToDimensionPixelSize(tv.data, mContext.getResources().getDisplayMetrics());
}
return result;
}
}
In layout xml, set your custom view behaviour as a app:layout_behavior in the view you want to handle.

Finally, use the layout and create ViewPager and Tabs in your Activity class.
MainActivity.java
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
((CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar)).setTitle(" ");
ViewPager viewPager = (ViewPager) findViewById(R.id.viewpager);
viewPager.setAdapter(new MyPagerAdapter(getSupportFragmentManager()));
PagerSlidingTabStrip tabsStrip = (PagerSlidingTabStrip) findViewById(R.id.tabs);
tabsStrip.setViewPager(viewPager);
}
public class MyPagerAdapter extends FragmentPagerAdapter {
final int PAGE_COUNT = 2;
private String tabTitles[] = new String[] { "Tab1", "Tab2" };
public MyPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public int getCount() {
return PAGE_COUNT;
}
#Override
public Fragment getItem(int position) {
return TestFragment.newInstance(position + 1);
}
#Override
public CharSequence getPageTitle(int position) {
return tabTitles[position];
}
}
}
Add following extra dependency in build.gradle along with appcompat and support library.
com.android.support:design:23.2.1
com.astuetz:pagerslidingtabstrip:1.0.1 (for ViewPager tabs)

As I am not sure if you want a particular or a general solution, I am going to give you my solution for your particular question. The key is to work with scrollFlags and collapseMode. If you really want to hide the tabs when the appBar is expanded, you can play with visibility.

How to handle scroll in NestedScrollView

What I want to do is to handle the scroll NestedScrollView.
But when I "setOnScrollChangedListener" to it, and then I scroll the view, nothing happens, the method "setOnScrollChangedListener" even isn't be called...
Who could tell me why? And when will the method "setOnScrollChangedListener" be called?

In MainActivity, I want to listen to the scroll. I did like this:
public class MainActivity extends AppCompatActivity {
private NestedScrollView nestedScrollView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
nestedScrollView = (NestedScrollView) findViewById(R.id.scroll);
nestedScrollView.setOnScrollChangeListener(new NestedScrollView.OnScrollChangeListener() {
#Override
public void onScrollChange(NestedScrollView v, int scrollX, int scrollY, int oldScrollX, int oldScrollY) {
System.out.println("I am scrolling the view...");
}
});
}
}

I tried the same code without
app:layout_behavior="#string/appbar_scrolling_view_behavior"
in the NestedScrollView and it worked for me. Give it a try
