Metodo 1:

Innanzitutto creare barra degli strumenti personalizzata

Link Library Tooltip

Visit

activity_login.xml

<?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:banner="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:fitsSystemWindows="true" 
android:background="@mipmap/background" 
tools:context="com.and.postanads.LoginActivity"> 

<android.support.design.widget.AppBarLayout 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    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="?attr/colorPrimary" 
     app:popupTheme="@style/AppTheme.PopupOverlay"> 

     <TextView 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:textAppearance="?android:attr/textAppearanceSmall" 
      android:text="SKIP" 
      android:textColor="#FFFFFF" 
      android:textStyle="bold" 
      android:fontFamily="sans-serif" 
      android:id="@+id/txt_skip" 
      android:layout_marginRight="15dp" 
      android:layout_gravity="right"/> 

    </android.support.v7.widget.Toolbar> 

</android.support.design.widget.AppBarLayout> 

LoginActivity.java

public class LoginActivity extends AppCompatActivity implements Tooltip.Callback { 


private Tooltip.ClosePolicy mClosePolicy = Tooltip.ClosePolicy.TOUCH_ANYWHERE_CONSUME; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_login); 
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 

    Tooltip.dbg = true; 

    TextView textView = (TextView)findViewById(R.id.txt_skip); 
    Tooltip.make(this, new Tooltip.Builder(101) 
       .anchor(textView, Tooltip.Gravity.BOTTOM) 
       .closePolicy(mClosePolicy, 5000) 
       .text("Tooltip on a TabLayout child...Tooltip on a TabLayout child...") 
       .withStyleId(R.style.ToolTipLayoutDefaultStyle_CustomFont) 
       .fadeDuration(200) 
       .fitToScreen(true) 
       .activateDelay(2000) 
       .withCallback(this) 
       .floatingAnimation(Tooltip.AnimationBuilder.DEFAULT) 
       .showDelay(400) 
       .build() 
     ).show(); 
    } 
} 

Sample

Metodo 2:

Uso menu_item

menu_login.xml

<?xml version="1.0" encoding="utf-8"?> 
<menu xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:app="http://schemas.android.com/apk/res-auto"> 
<item 
    android:id="@+id/menu_skip" 
    android:orderInCategory="100" 
    android:title="Skip" 
    app:showAsAction="always"/> 
</menu> 

LoginActivity.java

public class LoginActivity extends AppCompatActivity implements Tooltip.Callback { 
private Tooltip.ClosePolicy mClosePolicy = Tooltip.ClosePolicy.TOUCH_ANYWHERE_CONSUME; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_login); 
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 

    Tooltip.dbg = true; 
} 
@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    getMenuInflater().inflate(R.menu.menu_login, menu); 
    return true; 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    int id = item.getItemId(); 
    if (id == R.id.menu_skip) { 
     View view = findViewById(R.id.menu_skip); 
     Tooltip.make(this, new Tooltip.Builder(101) 
       .anchor(view, Tooltip.Gravity.BOTTOM) 
       .closePolicy(mClosePolicy, 5000) 
       .text("Tooltip on a TabLayout child...Tooltip on a TabLayout child...") 
       .fadeDuration(200) 
       .fitToScreen(true) 
       .activateDelay(2000) 
       .withCallback(this) 
       .floatingAnimation(Tooltip.AnimationBuilder.DEFAULT) 
       .showDelay(400) 
       .build() 
     ).show(); 
     return true; 
    } 
    return super.onOptionsItemSelected(item); 
} 
}
