Rounded corner for textview in android

I have a textview and want its corner to be in round shape. I already know it can be done using android:background="@drawable/somefile". In my case, this tag is already included so cannot use again. e.g android:background="@drawable/mydialogbox" is already there to create image in background

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:layout_gravity="top"
    android:background="@drawable/mydialogbox"
    android:orientation="horizontal" >

    <TextView
        android:id="@+id/textview_name"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true" />

    </LinearLayout>
    
</RelativeLayout>

so when I want textview(textview_name) also with round corner, how this can be achieved.

1. Create rounded_corner.xml in the drawable folder and add the following content,

   <?xml version="1.0" encoding="utf-8"?>
   <shape xmlns:android="http://schemas.android.com/apk/res/android" >         
      <stroke
          android:width="1dp"
          android:color="@color/common_border_color" />
                
      <solid android:color="#ffffff" />
        
      <padding
           android:left="1dp"
           android:right="1dp"
           android:bottom="1dp"
           android:top="1dp" />
        
      <corners android:radius="5dp" />
   </shape>
   

2. Set this drawable in the TextView background property like so:

   android:background="@drawable/rounded_corner"
   

I hope this is useful for you.

Beside radius, there are some property to round corner like topRightRadius, topLeftRadius, bottomRightRadius, bottomLeftRadius

Example TextView with red border with corner and gray background

bg_rounded.xml (in the drawables folder)

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <stroke
        android:width="10dp"
        android:color="#f00" />

    <solid android:color="#aaa" />

    <corners
        android:radius="5dp"
        android:topRightRadius="100dp" />
</shape>

TextView

<TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/bg_rounded"
    android:text="Text"
    android:padding="20dp"
    android:layout_margin="10dp"
    />

Result

With the Material Components Library you can use the MaterialShapeDrawable.

With a TextView:

    <TextView
        android:id="@+id/textview"
        ../>

You can programmatically apply a MaterialShapeDrawable:

float radius = getResources().getDimension(R.dimen.corner_radius);

TextView textView = findViewById(R.id.textview);
ShapeAppearanceModel shapeAppearanceModel = new ShapeAppearanceModel()
        .toBuilder()
        .setAllCorners(CornerFamily.ROUNDED,radius)
        .build();

MaterialShapeDrawable shapeDrawable = new MaterialShapeDrawable(shapeAppearanceModel);
ViewCompat.setBackground(textView,shapeDrawable);

If you want to change the background color and the border just apply:

shapeDrawable.setFillColor(ContextCompat.getColorStateList(this,R.color.....));
shapeDrawable.setStroke(2.0f, ContextCompat.getColor(this,R.color....));

Since your top level view already has android:background property set, you can use a <layer-list> (link) to create a new XML drawable that combines both your old background and your new rounded corners background.

Each <item> element in the list is drawn over the next, so the last item in the list is the one that ends up on top.

<?xml version="1.0" encoding="utf-8"?>
<layer-list
    xmlns:android="http://schemas.android.com/apk/res/android" >
    <item>
        <bitmap android:src="@drawable/mydialogbox" />
    </item>
    <item>
        <shape>
            <stroke
                android:width="1dp"
                android:color="@color/common_border_color" />

            <solid android:color="#ffffff" />

            <padding
                    android:left="1dp"
                    android:right="1dp"
                    android:top="1dp" />

            <corners android:radius="5dp" />
        </shape>
    </item>
</layer-list>

There is Two steps

1. Create this file in your drawable folder :- rounded_corner.xml

   http://schemas.android.com/apk/res/android" android:shape="rectangle"> // set radius of corner // set color and width of border // inner bgcolor

2. Set this file into your TextView as background property.

   android:background="@drawable/rounded_corner"

You can use this drawable in Button or Edittext also

You can use the provided rectangle shape (without a gradient, unless you want one) as follows:

In drawable/rounded_rectangle.xml:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners android:radius="5dp" />
    <stroke android:width="1dp" android:color="#ff0000" />
    <solid android:color="#00ff00" />
</shape>

Then in your text view:

android:background="@drawable/rounded_rectangle"

Of course, you will want to customize the dimensions and colors.

create an xml gradient.xml file under drawable folder

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle"  >
            <corners android:radius="50dip" />
            <stroke android:width="1dip" android:color="#667162" />
            <gradient android:angle="-90" android:startColor="#ffffff" android:endColor="#ffffff" />
        </shape>
    </item>
</selector>

then add this to your TextView

android:background="@drawable/gradient"

1. Right Click on Drawable Folder and Create new File
2. Name the file according to you and add the extension as .xml.
3. Add the following code in the file

  <?xml version="1.0" encoding="utf-8"?>
  <shape xmlns:android="http://schemas.android.com/apk/res/android"
      android:shape="rectangle">
      <corners android:radius="5dp" />
      <stroke android:width="1dp"  />
      <solid android:color="#1e90ff" />
  </shape>

4. Add the line where you want the rounded edge android:background="@drawable/corner"

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:id="@android:id/background">
        <shape>
            <corners android:radius="5dp" />
            <solid android:color="#ffffff"/>

        </shape>
    </item>
</layer-list>

You can use SVG for rounding corners and load into an ImageView and use ConstraintLayout to bring ImageView on TextView

I used it for rounded ImageView and rounded TextView

Put your TextView inside MaterialCardView:

    <com.google.android.material.card.MaterialCardView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:cardCornerRadius="25dp"
        >
        <com.google.android.material.textview.MaterialTextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/emergency_sms_template"
            android:padding="6dp"
            android:textSize="11sp"
            />
    </com.google.android.material.card.MaterialCardView>

> Simply using an rounded corner image as the background of that view

> And don't forget to have your custom image in drawable folder

android:background="@drawable/my_custom_image"
