How to hide ToolBar when I scrolling content up?
you have to do many changes in your both layout. first use CoordinatorLayout in activity_main.XML like below(change theme as per your requirement).
<?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"
android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.AppBarLayout>
<include layout="@layout/content_main" />
</android.support.design.widget.CoordinatorLayout>
in content_main.XML use android.support.v4.widget.NestedScrollView instead of ScrollView.
also use app:layout_behavior="@string/appbar_scrolling_view_behavior" inside android.support.v4.widget.NestedScrollView like below.
<android.support.v4.widget.NestedScrollView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="@+id/textone"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="hello world jheds sdjhs jds sjbs skjs ksjs kksjs ksj sdd dskd js sk "
android:textSize="25dp"
android:textStyle="bold" />
/// Add your other code here
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
How to make toolbar hide on scroll android studio
The Toolbar needs to be the child of an AppBarLayout for it to be able to hide on scroll. I believe the AppBarLayout must also be contained within a CoordinatorLayout as well.
The answer to this question from a while back has a nice working example: CoordinatorLayout doesn't hide the actionbar
Auto hide or show tool bar when scroll up android
I found the solution:
just make your toolbar and imageView in Layout with app:layout_scrollFlags="scroll|enterAlways"
like this
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_scrollFlags="scroll|enterAlways">
//ImageView
//Toolbar
</RelativeLayout>

What do I need to do to make my toolbar hide when I scroll?
The Feature you are requesting is called Collapsingtoolbarlayout And you can refer this
android:layout_height="200dp"
android:scaleType="centerCrop"
android:src="@drawable/photo"
app:layout_collapseMode="parallax"
app:layout_collapseParallaxMultiplier="0.7" />
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<include layout="@layout/content_scrolling" />
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="@dimen/fab_margin"
app:layout_anchor="@id/app_bar"
app:layout_anchorGravity="bottom|end"
app:srcCompat="@android:drawable/ic_dialog_info" />
after this you have to set menu items
<menu 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"
tools:context="com.journaldev.collapsingtoolbarlayout.ScrollingActivity">
<item
android:id="@+id/action_settings"
android:orderInCategory="100"
android:title="@string/action_settings"
app:showAsAction="never" />
<item
android:id="@+id/action_info"
android:orderInCategory="200"
android:title="info"
app:showAsAction="ifRoom"
android:icon="@android:drawable/ic_dialog_info"/>
And in java code do this
public class ScrollingActivity extends AppCompatActivity {
private Menu menu;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_scrolling);
final Toolbar mToolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(mToolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
AppBarLayout mAppBarLayout = (AppBarLayout) findViewById(R.id.app_bar);
mAppBarLayout.addOnOffsetChangedListener(new AppBarLayout.OnOffsetChangedListener() {
boolean isShow = false;
int scrollRange = -1;
@Override
public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
if (scrollRange == -1) {
scrollRange = appBarLayout.getTotalScrollRange();
}
if (scrollRange + verticalOffset == 0) {
isShow = true;
showOption(R.id.action_info);
} else if (isShow) {
isShow = false;
hideOption(R.id.action_info);
}
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
this.menu = menu;
getMenuInflater().inflate(R.menu.menu_scrolling, menu);
hideOption(R.id.action_info);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
} else if (id == R.id.action_info) {
return true;
}
return super.onOptionsItemSelected(item);
}
private void hideOption(int id) {
MenuItem item = menu.findItem(id);
item.setVisible(false);
}
private void showOption(int id) {
MenuItem item = menu.findItem(id);
item.setVisible(true);
}
}
