        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

This how my toolbar shows right now

回答1:

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

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>

回答2:

  <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="@color/color_blue"
            app:popupTheme="@style/AppTheme.PopupOverlay">

            <ImageView
                android:id="@+id/tv_header_title"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center"
                android:src="@mipmap/header_title" />
        </android.support.v7.widget.Toolbar>

You can set Event of button also by this method...

 public static void showToolBar(Toolbar toolbar,
                                   final AppCompatActivity activity) {
        activity.setSupportActionBar(toolbar);
        activity.getSupportActionBar().setDisplayShowTitleEnabled(false);
        @SuppressWarnings("deprecation")
        Drawable drawable = activity.getResources().getDrawable(
                R.mipmap.back_icon);
        drawable.setColorFilter(
                activity.getResources().getColor(R.color.color_white),
                android.graphics.PorterDuff.Mode.SRC_ATOP);
        activity.getSupportActionBar().setHomeAsUpIndicator(drawable);
        toolbar.setBackgroundColor(activity.getResources().getColor(
                R.color.color_blue));
        activity.getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        toolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                activity.finish();
            }
        });
    }

回答3:

Use the logo display on the action bar.

    getSupportActionBar().setLogo(R.drawable.logo);
    getSupportActionBar().setDisplayUseLogoEnabled(true);

回答4:

You missed to show the source

android:src="@drawable/yourImage"

if not working try adding some genuine width and height instead of wrap content

android:layout_width="50dp"
android:layout_height="50dp"  

回答5:

You should set the image src attribute rather than setting the imageview background drawable.

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/toolbartitle"
    />
