Android Relative layout: Basically android have 5 types of layouts, we will discuss them one by
one with examples-
1) LinearLayout
Here I am Introducing to Relative Layout:
As its name is Relative means each views are related to each other.
Like a button is below of first button or right of second button. That called
relation between views.
<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:orientation="vertical"
tools:context=".MainActivity" >
<Button
android:id="@+id/buttone1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:padding="5dp"
android:text="Button1" />
<Button
android:id="@+id/buttone2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/buttone1"
android:layout_marginTop="15dp"
android:padding="5dp"
android:text="Button2" />
<Button
android:id="@+id/buttone3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/buttone1"
android:layout_marginLeft="15dp"
android:layout_marginTop="15dp"
android:layout_toRightOf="@+id/buttone2"
android:padding="5dp"
android:text="Button3" />
<Button
android:id="@+id/buttone4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_below="@+id/buttone2"
android:layout_marginRight="10dp"
android:layout_marginTop="25dp"
android:padding="5dp"
android:text="Button4" />
<Button
android:id="@+id/buttone5"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/buttone4"
android:layout_marginLeft="15dp"
android:layout_marginTop="50dp"
android:padding="5dp"
android:text="Button5" />
<Button
android:id="@+id/buttone6"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:text="Button6" />
<Button
android:id="@+id/buttone7"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:padding="5dp"
android:text="Button7" />
</RelativeLayout>
And
use this MainActivity class to display your views-
package
com.androidhub4you.relativelayout;
import
android.app.Activity;
import android.os.Bundle;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
Your
comments and feedback are awaited!
Thank You!
