在Android Studio中点击不同的按钮时，如何在同一个textView中按顺序显示指定的按钮文本？

<TextView
    android:id="@+id/textView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="16sp"
    android:textColor="#000000" />

Button button1 = findViewById(R.id.button1);
Button button2 = findViewById(R.id.button2);
Button button3 = findViewById(R.id.button3);
final TextView textView = findViewById(R.id.textView);

button1.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        String buttonText = button1.getText().toString();
        String currentText = textView.getText().toString();
        textView.setText(currentText + buttonText);
    }
});

button2.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        String buttonText = button2.getText().toString();
        String currentText = textView.getText().toString();
        textView.setText(currentText + buttonText);
    }
});

button3.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        String buttonText = button3.getText().toString();
        String currentText = textView.getText().toString();
        textView.setText(currentText + buttonText);
    }
});
