在Android的ActionBar中显示图标和标题

Question

I want to display both icon and title in the action bar of an Activity. Here is the screenshot of my app now:

Now I need the app logo be displayed to the left of MyApp text in the action bar. I have already tried the following code to set the logo but nothing happened:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getSupportActionBar().setLogo(R.drawable.ic_launcher_web);
        getSupportActionBar().setDisplayUseLogoEnabled(true);
        setContentView(R.layout.activity_main);

    }

Answer 1

I just tried with your code, and this works.

    getSupportActionBar().setDisplayShowHomeEnabled(true);
    getSupportActionBar().setIcon(R.mipmap.ic_launcher);

Make sure your parent theme is set to Theme.AppCompat.Light.NoActionBar .

<!-- 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>

You can make a new layout for Action bar and you could implement in main activity
Create new Layout

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:minHeight="60dp"
android:id="@+id/topHeaderNav"
android:background="@color/primary"
android:layout_height="60dp"
tools:showIn="@layout/activity_main">

<ImageView
    android:layout_width="50dp"
    android:maxHeight="75dp"
    android:maxWidth="75dp"
    android:id="@+id/imgTop"
    android:layout_centerVertical="true"
    android:src="@drawable/mag"
    android:layout_height="wrap_content" />

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/topTitleText"
    android:layout_toRightOf="@id/imgTop"
    android:layout_centerVertical="true"
    android:layout_marginLeft="10dp"
    android:textSize="20sp"
    android:text="Magnetic Orange"
    android:textColor="#FFFFFF"
     />

and implement it in Main Layout

 `<include layout="@layout/navbar"
    android:id="@+id/topHeaderNavMainActivity"
    />`

I think it will help you

Answer 3

getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(true);

Answer 4

Fist of all be sure you have used style with NoActionBar

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
</style>

Set up your toolbar in onCreate() and be sure it's V7

Toolbar toolbar = (android.support.v7.widget.Toolbar) findViewById(R.id.toolbar);
toolbar.setLogo(R.drawable.ic_launcher);
setSupportActionBar(toolbar);

Your toolbar in xml looks like

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="60dp"/>

And use those methods you have previously tried. This will work.

Answer 5

if your require to customize a action bar then use costume layout in action bar, following was the code which explain how customize the action bar,

In your activity put this code onCreate method

getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM | ActionBar.DISPLAY_SHOW_HOME);
        LayoutInflater inflator = LayoutInflater.from(this);
        View v = inflator.inflate(R.layout.actionbar_layout, null); //hear set your costume layout
        getSupportActionBar().setCustomView(v);
        getSupportActionBar().setDisplayShowCustomEnabled(true);
        getSupportActionBar().setBackgroundDrawable(new ColorDrawable(Color.parseColor("#8731a0")));

it is the code which activiy inherit AppCompatActivity or if you are inheriting activity then replace getSupportActionBar() with getActionBar() and use.

     private ViewGroup actionBarLayout;

      protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_home_screen);
            context = this;

            actionBarLayout = (ViewGroup) getLayoutInflater().inflate(R.layout.custom_actionbar, null);

            actionBarLayout.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));

            // Set up your ActionBar

    /* final ActionBar actionBar = getActionBar();*/

            getSupportActionBar().setDisplayShowHomeEnabled(false);
            getSupportActionBar().setDisplayShowTitleEnabled(false);
            getSupportActionBar().setDisplayShowCustomEnabled(true);
            getSupportActionBar().setCustomView(actionBarLayout);
            getSupportActionBar().setBackgroundDrawable(new ColorDrawable(getResources().getColor(R.color.green)));

            init();
            event();
        }

and used following style.

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

    </style>

Answer 7

Try Custom ActionBar.

custom_actionbar.xml

Layout XML

<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize" 
    android:clickable="true"
    android:background="#ffffff">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="horizontal"
        android:layout_alignParentBottom="true"
        android:weightSum="1">

        <ImageView
            android:layout_width="50dp"
            android:layout_height="match_parent"
            android:layout_marginLeft="15sp"
            android:background="@drawable/emaact"
            android:layout_alignParentBottom="true"
            android:layout_margin="10dp"
            android:id="@+id/imageView"/>

        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:orientation="vertical"
            android:layout_gravity="right">

            <TextView
                android:layout_width="75dp"
                android:layout_height="match_parent"
                android:textAppearance="?android:attr/textAppearanceMedium"
                android:text="Project"
                android:layout_gravity="center_vertical"
                android:textSize="20sp"
                android:id="@+id/textView" android:gravity="center_vertical"
                android:textStyle="bold"/>

        </LinearLayout>

        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_weight="0.99"
            android:weightSum="1">

            <TextView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:id="@+id/txttitle"
                android:text="title"
                android:textStyle="normal"
                android:textSize="20sp"
                android:gravity="center"
                android:layout_weight="1.06"/>

        </LinearLayout>

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/menuline"
            android:layout_margin="10dp"
            android:id="@+id/slidingmenu"
            android:layout_gravity="center_vertical"/>

    </LinearLayout>
</RelativeLayout>

In Your MainActivity, Use This code.

MainActivity.java

public void customBar(){
    ActionBar actionBar = getSupportActionBar();
    actionBar.setDisplayShowHomeEnabled(false);
    actionBar.setDisplayShowTitleEnabled(false);

    LayoutInflater inflater = LayoutInflater.from(this);
    View customView = inflater.inflate(R.layout.custom_actionbar, null);

    TextView text =(TextView) customView.findViewById(R.id.txttitle);
    text.setText("Home");
    ImageView menus =(ImageView) customView.findViewById(R.id.slidingmenu);

    actionBar.setCustomView(customView);
    actionBar.setDisplayShowCustomEnabled(true);
}

Your Action Bar looks like... Custom ActionBar
