I've been looking for an answer and I've tried many possible solutions, but nothing seems to work..
I'm trying to setup a Material Action Bar following this tutorial.
Here's my code:
tool_bar.xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/ColorPrimary"
android:elevation="4dp">
</android.support.v7.widget.Toolbar>
activity.xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFFFFF">
<!-- The main content view -->
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include
android:id="@+id/app_bar"
layout="@layout/tool_bar" />
</RelativeLayout>
<!-- Navigation Drawer -->
<ListView
android:id="@+id/left_drawer"
android:layout_width="220dp"
android:layout_height="match_parent"
android:layout_gravity="left"
android:background="#1C1C1C"
android:divider="@android:color/darker_gray"
android:dividerHeight="1dp" />
</android.support.v4.widget.DrawerLayout>
And finally my activity.java:
import android.app.ActionBar;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toolbar;
public class rutaActivity extends ActionBarActivity {
private Toolbar toolbar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ruta);
getSupportActionBar().hide();//Ocultar ActivityBar anterior
toolbar = (Toolbar) findViewById(R.id.app_bar);
setSupportActionBar(toolbar); //HERE'S THE PROBLEM !!!!
Error:
setSupporActionBar (android.support.v7.widget.Toolbar) in ActionBarActivity cannot be applied to (android.widget.Toolbar)
How can I fix this?
In your Activity.java
import android.support.v7.widget.Toolbar
instead of android.widget.Toolbar
:
import android.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.support.v7.widget.Toolbar;
public class rutaActivity extends AppCompactActivity {
private Toolbar toolbar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ruta);
getSupportActionBar().hide();//Ocultar ActivityBar anterior
toolbar = (Toolbar) findViewById(R.id.app_bar);
setSupportActionBar(toolbar); //NO PROBLEM !!!!
Update:
If you are using androidx, replace
import android.support.v7.widget.Toolbar;
import android.support.v7.app.AppCompatActivity;
with newer imports
import androidx.appcompat.widget.Toolbar;
import androidx.appcompat.app.AppCompatActivity;
