    private static String TAG = MainActivity.class.getSimpleName();

    private Toolbar mToolbar;
    private FragmentDrawer drawerFragment;
    private String chng;
    private Intent i;
    public SearchView searchView;
    public SearchManager searchManager;

    // Alert Dialog Manager
    AlertDialogManager alert = new AlertDialogManager();

    SessionManager session;

    private String id;
    private boolean b;
    private String rasa;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        session = new SessionManager(getApplicationContext());
        id = getIntent().getStringExtra("id");

       mToolbar = (Toolbar) findViewById(R.id.toolbar);

        setSupportActionBar(mToolbar);
       getSupportActionBar().setDisplayShowHomeEnabled(false);
        getSupportActionBar().setDisplayShowTitleEnabled(false);

        drawerFragment = (FragmentDrawer)
                getSupportFragmentManager().findFragmentById(R.id.fragment_navigation_drawer);
        drawerFragment.setUp(R.id.fragment_navigation_drawer, (DrawerLayout) findViewById(R.id.drawerLayout),mToolbar);
        drawerFragment.setDrawerListener(this);
        displayView(0);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

这是我的工具栏现在显示的方式

This how my toolbar shows right now

推荐答案

相反，您可以将图像设置为textview背景.在代码中使用android:background="@drawable/toolbartitle".和setTitle(").

instead you can set your image as textview background. use android:background="@drawable/toolbartitle". and setTitle("") in your code.

您最终的工具栏将如下所示

your final toolbar will look like

 <?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:local="http://schemas.android.com/apk/res-auto"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="?attr/actionBarSize"
    android:background="@drawable/toolbartitle"
    local:theme="@style/MyMaterialTheme.Base"
    local:popupTheme="@style/ThemeOverlay.AppCompat.Light" >


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