android-Why custom actionbar doesn't fill the width

Question

this is my custom layout xml :

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#000"
    android:adjustViewBounds="true" 
    android:orientation="horizontal" >

    <ImageView
        android:id="@+id/weather"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/weather" />

    <ImageView
        android:id="@+id/like"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="5dp"
        android:src="@drawable/like" />

    <ImageView
        android:id="@+id/gps2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="5dp"
        android:src="@drawable/gps2" />

    <ImageView
        android:id="@+id/gps1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="5dp"
        android:src="@drawable/gps1" />

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:gravity="center_vertical|right"
        android:textSize="14sp"
        android:layout_weight="1"
        android:textColor="#fff"
        android:text="TextView" />

</LinearLayout>

this is my actionbar java code:

    ActionBar actionBar = getSupportActionBar();
        LayoutInflater layoutInflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View mCustomView = layoutInflater.inflate(R.layout.actionbar, null);
actionBar.setCustomView(mCustomView);
        actionBar.setDisplayShowCustomEnabled(true);
        getSupportActionBar().setDisplayShowCustomEnabled(true);
         actionBar.setDisplayShowTitleEnabled(false);
         actionBar.setDisplayHomeAsUpEnabled(true);
         actionBar.setDisplayUseLogoEnabled(false);
         actionBar.setDisplayShowHomeEnabled(false);
         actionBar.setHomeButtonEnabled(true);
         actionBar.setIcon(null);

this is the activity theme in manifest:

android:theme="@style/Theme.AppCompat.Light" 

This is the result :

as you can see , the black layout doesn't fill the width , I don't know why. How can I make custom actionbar to fill the screen width ?

Answer 1

In your actionbar java code, replace

actionBar.setCustomView(mCustomView);

with

actionBar.setCustomView(mCustomView, new Toolbar.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));

Hope this help you.!
