How to make TextView shape circle and set different background color based on condition

Question

I have a TextView, what I want is to make the TextView shape circle and then set different background colors based on different conditions I have used. I am able to set Background color based on different conditions but not able to make the TextView shape circle. So how that can be done. Please help me to solve this out.

Code I have used:

TextView txt_stage_display = (TextView)findViewById(R.id.txt_stage_display);

if(m_enStage[position] == enSTAGE_START)
{
    txt_stage_display.setBackgroundColor(Color.parseColor("#D48393"));
}
else if(m_enStage[position] == enSTAGE_FLOW)
{
    txt_stage_display.setBackgroundColor(Color.parseColor("#D48393"));
}
    else if(m_enStage[position] == enSTAGE_SAFE)
{
    txt_stage_display.setBackgroundColor(Color.parseColor("#66B0CC"));
}
else if(m_enStage[position] == enSTAGE_UNSAFE)
{
    txt_stage_display.setBackgroundColor(Color.parseColor("#D8C627"));
}
else if(m_enStage[position] == enSTAGE_FERTILE)
{
    txt_stage_display.setBackgroundColor(Color.parseColor("#67A05E"));
}
else
{
    txt_stage_display.setBackgroundColor(Color.parseColor("#808080"));
}

If you have a relatively small amout of colors, you can create a drawable file for each color, for example create a file bg_red.xml:

<?xml version="1.0" encoding="utf-8"?>
<item xmlns:android="http://schemas.android.com/apk/res/android">
  <shape>
      <solid android:color="#f00" />
      <corners
          android:topLeftRadius="30dp"
          android:topRightRadius="30dp"
          android:bottomLeftRadius="30dp"
          android:bottomRightRadius="30dp"
          />
  </shape>
</item>

Then assign define the TextView:

<TextView 
    android:id="@+id/tv"
    android:layout_height="60dp"
    android:layout_width="60dp" 
    android:text="X" 
    android:textColor="#fff"
    android:textSize="20sp"
    android:background="@drawable/bg_red"
    android:gravity="center_vertical|center_horizontal" 
    />

Note that the width is twice the radius of the background corner radius.

To change the color from code:

TextView v = (TextView) findViewById(R.id.my_text_view);
v.setBackgroundResource(R.drawable.bg_blue);
