2.1 Main Activity Java File.

1. MainActivity.java

   package com.dev2qa.textviewcolor;
   
   import android.graphics.Color;
   import android.support.v7.app.AppCompatActivity;
   import android.os.Bundle;
   import android.view.View;
   import android.widget.Button;
   import android.widget.TextView;
   
   import org.w3c.dom.Text;
   
   public class MainActivity extends AppCompatActivity {
   
       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);
   
           setTitle("dev2qa.com - Android Set TextView Foreground Background Color Example.");
   
           // Get the textview object.
           final TextView textView = (TextView)findViewById(R.id.text_view);
   
           // Get set text view foreground color button and make button text as normal.
           Button setForeGroundColorButton = (Button)findViewById(R.id.button_set_foreground_color);
           setForeGroundColorButton.setAllCaps(false);
           setForeGroundColorButton.setOnClickListener(new View.OnClickListener() {
               @Override
               public void onClick(View view) {
                     textView.setTextColor(Color.BLUE);
               }
           });
   
           // Get set text view background color button.
           Button setBackGroundColorButton = (Button)findViewById(R.id.button_set_background_color);
           setBackGroundColorButton.setAllCaps(false);
           setBackGroundColorButton.setOnClickListener(new View.OnClickListener() {
               @Override
               public void onClick(View view) {
                   textView.setBackgroundColor(Color.YELLOW);
               }
           });
       }
   }
