Toolbar

一、取消actionbar

style

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

activity_main

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent" android:layout_height="match_parent">
    <FrameLayout
        android:layout_width="match_parent" android:layout_height="match_parent">
    <android.support.v7.widget.Toolbar
        android:id="@+id/toobar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
        >
    </android.support.v7.widget.Toolbar>
    </FrameLayout>
<TextView
    android:text="hah"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:background="@android:color/holo_blue_dark"
    />


    </android.support.v4.widget.DrawerLayout>

3、菜单

<?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/setting"
        android:icon="@drawable/ic_settings"
        app:showAsAction="never"
        android:title="设置"
        ></item>
</menu>

效果

优化：

public class MainActivity extends AppCompatActivity {

    private DrawerLayout drawerLayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar= (Toolbar) findViewById(R.id.toobar);
        setSupportActionBar(toolbar);
        drawerLayout = (DrawerLayout) findViewById(R.id.DrawerLayout);
       ActionBar actionBar= getSupportActionBar();
        if (actionBar!=null){
            actionBar.setDisplayHomeAsUpEnabled(true);
            actionBar.setHomeAsUpIndicator(R.drawable.ic_menu);
        }
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
       getMenuInflater().inflate(R.menu.toolbar,menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch(item.getItemId()){
            case R.id.home:
                drawerLayout.openDrawer(GravityCompat.START);
                break;
            case R.id.setting:

                break;
        }
        return true;
    }
}
