I want to create DetailActivity for My app . I want To achieve layout some thing like This .
Look at to the green rectangle .it is contain Toolbar and Tablayout .
When we scroll down and when toolbar Touch the Tablayout . They pinned to the top of the screen.
I Think this Layout use the Scroll and ... and use The Toolbar and Tablayout in The Activity .
This is my code where I try to achieve That.but nothing ...
DeatailActivity.java
import android.content.Intent;
import android.support.design.widget.TabLayout;
import android.support.v4.app.FragmentManager;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import ir.dink.sevom.R;
import ir.dink.sevom.adapters.*;
public class DetailActivity extends AppCompatActivity {
private ViewPager detailActivityViewPager;
private TabLayout detailActivityTabLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_detail);
initToolbar();
initTablayout();
}
//============================ Init Toolbar ===================================//
private void initToolbar() {
Toolbar mainToolbar = (Toolbar)findViewById(R.id.toolbar_detail_activity);
setSupportActionBar(mainToolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
//========================== OnCreate Option Menu =====================================//
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
//=============================== onOption Item Selected ================================//
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()){
case R.id.search_action_toolbar:
// startActivity(new Intent(MainActivity.this ,DetailActivity.class ));
return true;
default:
return super.onOptionsItemSelected(item);
}
}
private void initTablayout() {
detailActivityViewPager = (ViewPager) findViewById(R.id.view_pager_detail_activity);
detailActivityTabLayout = (TabLayout) findViewById(R.id.tab_layout_detail_activity);
FragmentManager manager = getSupportFragmentManager();
DetailActivityPagerAdapter detailadapter = new DetailActivityPagerAdapter(manager);
detailActivityViewPager.setAdapter(detailadapter);
detailActivityViewPager.setCurrentItem(detailActivityViewPager.getAdapter().getCount() - 1);
detailActivityTabLayout.setupWithViewPager(detailActivityViewPager);
detailActivityViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(detailActivityTabLayout));
}
}

}
return super.onOptionsItemSelected(item);
}
}
Is there any idea ?. I have got the bottom navigation as follows : here
Changing padding at the Bottom to small a value like:
android:paddingBottom="2dp"
Also your BottomNavigationView appears to be a square of 168dp size. Is this intentionally? Change the height it or view its layout bounds. It may be very big by itself like a square.
This question already has answers here:
The application icon does not show on action bar

Closed 5 years ago.
In my Android application, I'm trying to use setlogo(), ActionBar and android:icon but they don't work as expected: Output shows absolutely no icon and I'm really confusing about it. I need your help.
My code:
import android.content.Intent;
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends AppCompatActivity {
RecyclerView recyclerView;
Toolbar toolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setIcon(R.mipmap.ic_launcher_round);
//recyclerview
recyclerView= (RecyclerView) findViewById(R.id.recycle_main);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setHasFixedSize(true);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_mainactivity,menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()){
case R.id.menu_add_contects:
startActivity(new Intent(MainActivity.this,AddContects.class));
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}
To set an icon in your ActionBar you need to call
setHomeAsUpIndicator() instead of setIcon()
Like this:
final ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setHomeAsUpIndicator(R.drawable.ic_arrow_back);
actionBar.setDisplayHomeAsUpEnabled(true);
}
You can set any image in toolbar using the following code.
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" >
<RelativeLayout
android:layoutDirection="ltr"
android:gravity="center_vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/camera"
android:src="#drawable/camera"
android:layout_toStartOf="#+id/search"
android:paddingStart="#dimen/margin_10"
android:paddingEnd="#dimen/margin_10"
android:layout_width="wrap_content"
android:layout_height="match_parent" />
<ImageView
android:id="#+id/search"
android:layout_alignParentEnd="true"
android:src="#drawable/search"
android:paddingStart="#dimen/margin_10"
android:paddingEnd="#dimen/margin_10"
android:layout_marginEnd="#dimen/margin_6"
android:layout_width="wrap_content"
android:layout_height="match_parent" />
</RelativeLayout>
</android.support.v7.widget.Toolbar>
I have an issue that I can't seem to solve.
I have an activity with a list fragment (landscape and portrait) and an addItem fragment.
There is a FloatingActionButton on the Activity, but I can't seem to figure out how to set up its onClickListener.
The getViewById always returns null so the setOnClickListener has no object to call from. Why is this and how do I fix it?
Am I doing multiple fragments wrong and this is my problem?
Note: I left out the landscape fragment/layout for brevity's sake. It's the same as the portrait with a different id.

Please change this portion of the code in the MainActivity
FROM
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
setContentView(R.layout.fragment_list);
TO
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
Mistakes::
--Passing wrong xml instance::
--Trying to fetch the toolbar before the xml was actually set..
Please tell if more assistance needed
setContentView(R.layout.fragment_list);
This sets the layout used for your activity which does not have a FAB. Change this line to
setContentView(R.layout.activity_main);
In general, whenever findViewById() returns null, you need to be sure that the correct XML is loaded and that it contains the id you are trying to find.
I want something like the swiping pages in the Google Play Store.

Tried multiple things found on the internet, changing xml etc doesn't do the trick.
In xml you have to put below Toolbar code for the action bar:
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/colorPrimary"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
</android.support.v7.widget.Toolbar>
In java file:
a. extend class with AppCompatActivity
b. you have to put the below code for set the title:
Toolbar mActionBarToolbar = (Toolbar) findViewById(R.id.toolbar);
mActionBarToolbar.setTitle("Pluff");
setSupportActionBar(mActionBarToolbar);
In manifest file you have to set theme for the activity, see below:
<activity
android:name=".MainActivityPage"
android:label="#string/app_name"
android:theme="#style/Theme.AppCompat.Light.NoActionBar"
>
</activity>
I have an activity that has a support action bar, below that a sliding tab layout, below that a listview of images for the corresponding tab. I just want to hide the support action bar not the sliding tab strip and I am not able to hide it.

</android.support.v7.widget.Toolbar>
Edit: Here is my layout for fragment that is shown in the tabs.
<FrameLayout 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:background="#231F20"
tools:context="com.pipipzz.simpleapp.ArchitectureFragment">
<ListView
android:id="#+id/listView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:divider="#null"
android:dividerHeight="0dp"
android:scrollingCache="true"
android:smoothScrollbar="true" />
</FrameLayout>
Any help would be highly appreciated.
Please have a look at this library Android-ObservableScrollView
It has a lot of examples and it will be much easier to use it in your case.
There are several examples of using it with Toolbar, that you are currently using in your code.
It would be better if you prodived all source code to run it, maybe you have issue somewhere else.
First about your code. Don't use findViewById whenever you want, it is really heavy method. So when you are doing this each time onScrollViewChanged it makes your app laggy.
Find your scroll view only once in onCreate method
mMainScrollView = findViewById(R.id.parent);
mMainScrollView.getViewTreeObserver().addOnScrollChangedListener(new OnScrollChangedListener() {#Override
public void onScrollChanged() {
int scrollY = rootScrollView.getScrollY(); //for verticalScrollView
// Hide or show toolbar here
}
});
Why not directly to call hide on toolbar without getting support
action bar ? Try do to it directly on toolbar.
If you call hide
method directly on ActionBar/Toolbar does it work ?
Try to do something like this
To hide toolbar
toolbar.animate().translationY(-toolbar.getBottom()).setInterpolator(new AccelerateInterpolator()).start();
And show it again
toolbar.animate().translationY(0).setInterpolator(new DecelerateInterpolator()).start();
