当其他edittext被聚焦时，如何计算edittext上的值？

import android.os.Bundle;
import android.text.Editable;
import android.text.TextWatcher;
import android.view.View;
import android.widget.EditText;
import android.widget.Toast;
import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    private EditText editText1;
    private EditText editText2;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        editText1 = findViewById(R.id.editText1);
        editText2 = findViewById(R.id.editText2);

        // 设置焦点变化监听器
        editText1.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (!hasFocus) {
                    calculateValue(editText1);
                }
            }
        });

        editText2.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (!hasFocus) {
                    calculateValue(editText2);
                }
            }
        });
    }

    private void calculateValue(EditText editText) {
        String value = editText.getText().toString();
        try {
            // 假设我们要计算输入值的平方
            double inputValue = Double.parseDouble(value);
            double result = inputValue * inputValue;
            Toast.makeText(this, "计算结果: " + result, Toast.LENGTH_SHORT).show();
        } catch (NumberFormatException e) {
            Toast.makeText(this, "请输入有效的数字", Toast.LENGTH_SHORT).show();
        }
    }
}
