How to draw rounded rectangle in Android UI?

Question

I need to draw a rounded rectangle in the Android UI. Having the same rounded rectangle for TextView and EditText would also be helpful.

Answer 1

In monodroid, you can do like this for rounded rectangle, and then keeping this as a parent class, editbox and other layout features can be added.

 class CustomeView : TextView
    {
       public CustomeView (Context context, IAttributeSet ) : base (context, attrs)  
        {  
        }
       public CustomeView(Context context, IAttributeSet attrs, int defStyle) : base(context, attrs, defStyle)  
        {  
        }
       protected override void OnDraw(Android.Graphics.Canvas canvas)
       {
           base.OnDraw(canvas);
           Paint p = new Paint();
           p.Color = Color.White;
           canvas.DrawColor(Color.DarkOrange);

           Rect rect = new Rect(0,0,3,3);

           RectF rectF = new RectF(rect);


           canvas.DrawRoundRect( rectF, 1,1, p);



       }  
    }
}

Answer 2

Right_click on the drawable and create new layout xml file in the name of for example button_background.xml. then copy and paste the following code. You can change it according your need.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners
android:radius="14dp" />
<solid android:color="@color/colorButton" />
<padding
android:bottom="0dp"
android:left="0dp"
android:right="0dp"
android:top="0dp" />
<size
android:width="120dp"
android:height="40dp" />
</shape>

Now you can use it.

<Button
android:background="@drawable/button_background"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
