Try this

    <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >

        <RelativeLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" >

            <TextView
                android:id="@+id/num_txt"
                android:layout_width="100dp"
                android:layout_height="100dp"
                android:layout_marginTop="0dp"
                android:background="@drawable/bg_red"
                android:gravity="center"
                android:text="My name is NON"
                android:textColor="#FFFFFF"
                android:textSize="10dp" />

        </RelativeLayout>

    </RelativeLayout>

Save in drawable bg_red.xml

    <?xml version="1.0" encoding="utf-8"?>
    <shape xmlns:android="http://schemas.android.com/apk/res/android" 
        android:shape="oval">
        <corners android:radius="10dip"/>
        <stroke android:color="#FF0000" android:width="5dip"/>
        <solid android:color="#FF0000"/>
    </shape>

Edited Code

    <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="wrap_content"
        android:layout_height="match_parent" >
         <TextView
             android:id="@+id/num_txt"
             android:layout_width="185dp"
             android:layout_height="185dp"

             android:layout_alignParentTop="true"
             android:layout_marginTop="163dp"
             android:background="@drawable/bg_red"
             android:gravity="center"
             android:text="My name is NON"
             android:textColor="#FFFFFF"
             android:layout_marginLeft="10dp"
             android:textSize="10dp" />

         <TextView
             android:id="@+id/TextView02"
             android:layout_width="90dp"
             android:layout_height="90dp"
             android:layout_alignParentRight="true"
             android:layout_alignTop="@+id/TextView01"
             android:layout_marginRight="90dp"
             android:layout_marginTop="122dp"
             android:background="@drawable/bg_red"
             android:gravity="center"
             android:text="My name is NON"
             android:textColor="#FFFFFF"
             android:textSize="10dp" />

         <TextView
             android:id="@+id/TextView01"
             android:layout_width="120dp"
             android:layout_height="120dp"
             android:layout_alignTop="@+id/num_txt"
             android:layout_toRightOf="@+id/num_txt"
             android:background="@drawable/bg_red"
             android:gravity="center"
             android:text="My name is NON"
             android:textColor="#FFFFFF"
             android:textSize="10dp" />

    </RelativeLayout>

ConstraintLayout use for badge count.

    <android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@android:color/transparent"
        android:gravity="center">

        <ImageView
            android:id="@+id/tab_icon"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:adjustViewBounds="true"
            android:background="@android:color/transparent"
            android:scaleType="centerInside"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintRight_toRightOf="parent"
            app:layout_constraintTop_toTopOf="parent"
            app:srcCompat="@drawable/ic_home"
            tools:layout_constraintBottom_creator="1"
            tools:layout_constraintLeft_creator="1"
            tools:layout_constraintRight_creator="1"
            tools:layout_constraintTop_creator="1" />

        <TextView
            android:id="@+id/tab_badge"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_marginBottom="10dp"
            android:background="@drawable/icon_badge"
            android:paddingBottom="1dp"
            android:paddingLeft="6dp"
            android:paddingRight="6dp"
            android:paddingTop="1dp"
            android:text="10"
            android:textAppearance="@style/TextAppearance.AppCompat.Small"
            android:textColor="@android:color/white"
            android:textSize="12dp"
            app:layout_constraintBottom_toBottomOf="@+id/tab_icon"
            tools:layout_constraintLeft_creator="1"
            android:layout_marginLeft="14dp"
            app:layout_constraintLeft_toLeftOf="@+id/tab_icon" />
    </android.support.constraint.ConstraintLayout>

Answer 2

Try this code to create dynamically circle with textview

RelativeLayout main_rel_layout = findViewById(R.id.main_rel_layout);
TextView textView = new TextView(this);
RelativeLayout relativeLayout = new RelativeLayout(this);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.CENTER_IN_PARENT);
textView.setText("Hello ");
textView.setTextSize(100);
textView.setLayoutParams(params);
textView.setGravity(Gravity.CENTER);

final FrameLayout frameLayout = new FrameLayout(this);
FloatingActionButton floatingActionButton = new FloatingActionButton(this);
floatingActionButton.setCustomSize(400);
frameLayout.addView(floatingActionButton);

relativeLayout.addView(frameLayout);
relativeLayout.addView(textView);
main_rel_layout.addView(relativeLayout);

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    final TextView tv = (TextView) findViewById(R.id.tv);
    Button btn = (Button) findViewById(R.id.btn);
    GradientDrawable gd = new GradientDrawable();
    gd.setShape(GradientDrawable.OVAL);
    gd.setColor(Color.TRANSPARENT);
    gd.setStroke(5, Color.BLUE);
    gd.setSize(getTextViewHeight(tv),getTextViewHeight(tv));

    tv.setBackground(gd);
    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            GradientDrawable gd = new GradientDrawable();
            gd.setShape(GradientDrawable.OVAL);
            gd.setColor(Color.TRANSPARENT);
            gd.setStroke(5, Color.BLUE);
            gd.setSize(tv.getHeight(),tv.getHeight());
            Log.d("DB121","Width "+tv.getHeight()+ "Height ="+tv.getHeight());
            tv.setBackground(gd);
        }
    });
}
public static int getTextViewHeight(TextView textView) {
    WindowManager wm =
            (WindowManager) textView.getContext().getSystemService(Context.WINDOW_SERVICE);
    Display display = wm.getDefaultDisplay();

    int deviceWidth;

    if(android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2){
        Point size = new Point();
        display.getSize(size);
        deviceWidth = size.x;
    } else {
        deviceWidth = display.getWidth();
    }

    int widthMeasureSpec = View.MeasureSpec.makeMeasureSpec(deviceWidth, View.MeasureSpec.AT_MOST);
    int heightMeasureSpec = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED);
    textView.measure(widthMeasureSpec, heightMeasureSpec);
    return textView.getMeasuredHeight();
}

</RelativeLayout>

you can set directly backroud or drawable to the textview. you can use drawablepadding ,etc.....

or you can use: android:drawableStart="@drawable/ic_cab_done_holo_dark"

Try this

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.util.AttributeSet;
import android.widget.TextView;

public class CircularTextView extends TextView
{
private float strokeWidth;
int strokeColor,solidColor;

public CircularTextView(Context context) {
    super(context);
}

public CircularTextView(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public CircularTextView(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
}


@Override
public void draw(Canvas canvas) {

    Paint circlePaint = new Paint();
    circlePaint.setColor(solidColor);
    circlePaint.setFlags(Paint.ANTI_ALIAS_FLAG);

    Paint strokePaint = new Paint();
    strokePaint.setColor(strokeColor);
    strokePaint.setFlags(Paint.ANTI_ALIAS_FLAG);

    int  h = this.getHeight();
    int  w = this.getWidth();

    int diameter = ((h > w) ? h : w);
    int radius = diameter/2;

    this.setHeight(diameter);
    this.setWidth(diameter);

    canvas.drawCircle(diameter / 2 , diameter / 2, radius, strokePaint);

    canvas.drawCircle(diameter / 2, diameter / 2, radius-strokeWidth, circlePaint);

    super.draw(canvas);
}

public void setStrokeWidth(int dp)
{
    float scale = getContext().getResources().getDisplayMetrics().density;
    strokeWidth = dp*scale;

}

public void setStrokeColor(String color)
{
    strokeColor = Color.parseColor(color);
}

public void setSolidColor(String color)
{
    solidColor = Color.parseColor(color);

}
}
