Answer 1

you can save and check your high score by using sharedpreferences. Like this:

these lines Under set_ContentView at the start:

String PREFS_GAME ="your package name";
SharedPreferences sp = getSharedPreferences(PREFS_GAME,Context.MODE_PRIVATE);
final Integer oldrec  = sp.getInt("record",0);

then write this code in setOnclicklistenre:

if (newrec>oldrec){
                sp.edit().putInt("record",new rec).commit();
                Toast.makeText(MainActivity.this,"your new record is :"+newrec, Toast.LENGTH_SHORT).show();
                }

Answer 2

i recomend:

public class MainActivity extends AppCompatActivity {

private int clicks = 0;
private TextView mTextView;
Button bt_restart;
int high;
public static final String MyPREFERENCES = "MyPrefs" ;
public static final String HIGHSCORE = "high" ;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    SharedPreferences prefs = getSharedPreferences(MyPREFERENCES, MODE_PRIVATE); 
    high = prefs.getInt(HIGHSCORE, 0); 
    bt_restart = (Button)findViewById(R.id.restart);
    bt_restart.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent restartIntent = getBaseContext().getPackageManager()
                    .getLaunchIntentForPackage(getBaseContext().getPackageName());
            restartIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            startActivity(restartIntent);
        }
    });

    mTextView = (TextView) findViewById(R.id.total_textview);
    mTextView.setVisibility(View.VISIBLE);

    Button button = (Button) findViewById(R.id.count_button);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(final View v) {
            final Button b = (Button)v;
            if (clicks == 0){
                // Means its the first time that a user click the button
                // Start a thread that is going to disable the button after 5 seconds from first click
                new CountDownTimer(15000, 1000) {
                    public void onTick(long millisUntilFinished) {
                        b.setText(millisUntilFinished / 1000 + " Seconds");
                    }

                    public void onFinish() {
                        b.setText("Time up");
                        b.setEnabled(false);
                        // Showing user clicks after button is disabled
                        showClicks();
                    }
                }.start();
            }
            // Here we are just counting  . . . . including the first click
            countClicks();
        }
    });

}


private void countClicks(){
    ++clicks;
    mTextView.setText(Integer.toString(clicks));

    // You can update your text view here
}
private void showClicks(){
    mTextView.setText(String.valueOf(clicks)+"Clicks");
    mTextView.setVisibility(View.VISIBLE);
    if(clicks > high){
        SharedPreferences.Editor editor = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE).edit();
        editor.putInt(HIGHSCORE, clicks);
        editor.commit();
        high = prefs.getInt(HIGHSCORE, 0); 
    }    
}

then if you you want to show the highscore use a textview and in the setText use String.valueOf(high), i don't know if the textview would change when change the variable high maybe you must the textview.setText everyTima you edit the variable high (code based on that link: Android Shared preferences example)
