Android Material design error
Hello, I am learning to create a Material design using this tutorial. https://www.youtube.com/watch?v=pMO8EVkhJO8&list=PLonJJ3BVjZW6CtAMbJz1XD8ELUs1KXaTD&index=3
In my design, all sides of the appbar have padding. Can anyone help me remove this padding and make the app look like a real app bar.
app_bar
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="wrap_content"
android:background="#DDDD">
</android.support.v7.widget.Toolbar>
Primary activity
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=". MainActivity">
<include android:id="@+id/app_bar" layout="@layout/app_bar"/>
<TextView
android:layout_below="@+id/app_bar"
android:text="@string/hello_world" android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
maniActivity.java
private Toolbar toolbar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.app_bar);
setSupportActionBar(toolbar);
}
Solution
In your relative layout, you placed padding. You need to delete them.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=". MainActivity">
<include android:id="@+id/app_bar" layout="@layout/app_bar"/>
<TextView
android:layout_below="@+id/app_bar"
android:text="@string/hello_world"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
Check this. There will be no padding on the toolbar right now. If you want to populate other children, make a parent layout using LinearLayout
and vertical
orientation
, and add two toolbars
and relativelayouts
to it.
