与えられたアップデートで、あなたのコードを置き換えの画像です：私はここで、ここでのJavaコードお願いします

public class MainActivity extends AppCompatActivity implements View.OnClickListener { 
    private Button btnred,btngreen,btnblue,btnpluse,btnsave; 
    private LinearLayout mlinearLayout; 
    private TextView tv; 
    int point = 0; 
    public SharedPreferences sp,prefs; 
    private int progress; 


    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     SharedPreferences prefs = getSharedPreferences("save", MODE_PRIVATE); 
     String textValue= prefs.getString("textValue", "0"); 

     mlinearLayout=(LinearLayout)findViewById(R.id.activity_main); 
     SharedPreferences sp = getSharedPreferences("saveColour", MODE_PRIVATE); 
     int colourValue = sp.getInt("colourValue", Color.WHITE); 
     mlinearLayout.setBackgroundColor(colourValue); 

     btnred = (Button) findViewById(R.id.cred); 
     btnblue = (Button) findViewById(R.id.cblue); 
     btngreen = (Button) findViewById(R.id.cgreen); 
     btnpluse = (Button)findViewById(R.id.btnadd); 
     btnsave = (Button)findViewById(R.id.save); 
     tv=(TextView)findViewById(R.id.tv) ; 
     tv.setText(textValue); 
     btnred.setOnClickListener(this); 
     btnsave.setOnClickListener(this); 
     btnpluse.setOnClickListener(this); 
     btnblue.setOnClickListener(this); 
     btngreen.setOnClickListener(this); 


     } 



    @Override 
    public void onClick(View v) { 
     if (btnred == v){ 
      mlinearLayout.setBackgroundColor(Color.RED); 
      SharedPreferences.Editor editor = getSharedPreferences("saveColour", MODE_PRIVATE).edit(); 
      editor.putInt("colourValue", Color.RED); 
      editor.commit(); 

     } 
     else if (btngreen == v){ 
      mlinearLayout.setBackgroundColor(Color.GREEN); 
      SharedPreferences.Editor editor = getSharedPreferences("saveColour", MODE_PRIVATE).edit(); 
      editor.putInt("colourValue", Color.GREEN); 
      editor.commit(); 
     } 
     else if (btnblue == v){ 
      mlinearLayout.setBackgroundColor(Color.BLUE); 
      SharedPreferences.Editor editor = getSharedPreferences("saveColour", MODE_PRIVATE).edit(); 
      editor.putInt("colourValue", Color.BLUE); 
      editor.commit(); 


     } 
     else if (btnpluse== v){ 
      point++; 
      tv.setText("" + point); 

     } 
     else if (btnsave == v){ 
      Toast.makeText(this,"btn clickd",Toast.LENGTH_LONG).show(); 
      SharedPreferences.Editor editor = getSharedPreferences("save", MODE_PRIVATE).edit(); 
      editor.putString("textValue", tv.getText().toString()); 
      editor.commit(); 
     } 
    } 
}
