Answer 1

Try this

@Override
    public void onCreate(Bundle SavedInstanceState) {
        super.onCreate(SavedInstanceState);
        setContentView(R.layout.activity_main);
         button1 = (Button)findViewById(R.id.button1);
         button2 = (Button)findViewById(R.id.button2);
        //Listeneři
        button1.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                button1.setText("Správně.");
            }
        });

        button2.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
            button2.setText("COŽE!?");
