public class MainActivity extends AppCompatActivity implements View.OnClickListener{
    Button javauyu, javasavas, javayemek;
    TextView javaeylem, javaistatistik;
    Karakter k;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        k = new Karakter();
        javauyu = (Button)findViewById(R.id.bt_uyu);
        javasavas = (Button)findViewById(R.id.bt_savas);
        javayemek = (Button)findViewById(R.id.bt_yemek);
        javaeylem = (TextView)findViewById(R.id.tv_eylem);
        javaistatistik = (TextView)findViewById(R.id.tv_istatistik);
        javauyu.setOnClickListener(this);
        javayemek.setOnClickListener(this);
        javasavas.setOnClickListener(this);
        k.kilo = 50;
        k.action = 10;
        k.attackD = 80;
        javaistatistik.setText(k.toString());
    }

    @Override
    public void onClick(View v) {
        if (v.getId() == javauyu.getId())
        {
            javaeylem.setText(k.komutuyu());
        }
        else if (v.getId() == javasavas.getId())
        {
            javaeylem.setText(k.komutsavas());
        }
        else if (v.getId() == javayemek.getId())
        {
            javaeylem.setText(k.komutye());
        }
        javaistatistik.setText(k.toString());

Answer 1

This is your issue

android:padding="@string/pad"

padding and textsize need to get a dimension like 10dp, not a string
