How to display specified text of buttons in the same textView in sequence when different buttons are clicked in Android Studio? - android-studio

Question

I am having a problem in Android Studio. I have got two different buttons and a textView. The effect that I want is as follows:
CASE 1: When bt1 is clicked, "A" is displayed in textView. When the bt2 is clicked, "G" is added in textView so the textView displays "AG".
CASE 2: When bt1 is clicked, "A" is displayed in textView. When bt1 is clicked again, it disappears and the textView is empty.
CASE 3: When CASE 1 is done, as bt1 is clicked, "A" is removed so that textView displays"G".
Your help in altering my code is much appreciated. Thanks in advance!!
Main Activity code:
public class keyboard extends AppCompatActivity {
Button btn1,btn2,btn3;
TextView text;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_keyboard);
text=(TextView)findViewById(R.id.txt);
btn1=(Button)findViewById(R.id.bt1);
btn2=(Button)findViewById(R.id.bt2);
btn1.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v){
text.setText("A");
text.setVisibility(text.getVisibility() == View.VISIBLE ? View.GONE : View.VISIBLE);
}
});
btn2.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v){
text.setText(text.getText() + "G");
text.setVisibility(text.getVisibility() == View.VISIBLE ? View.GONE : View.VISIBLE);
}
});}}

Here you go..
public class Keyboard extends AppCompatActivity {
Button btn1, btn2;
TextView text;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_keyboard);
text = findViewById(R.id.txt);
btn1 = findViewById(R.id.bt1);
btn2 = findViewById(R.id.bt2);
btn1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
text.setVisibility(View.VISIBLE);
if (text.getText().equals("A")) {
text.setText("");
text.setVisibility(View.GONE);
} else if (text.getText().equals("AG")) {
text.setText("G");
} else {
text.setText("A");
}
}
});
btn2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
text.setText(String.format("%sG", text.getText()));
}
});
}
}
