Android studio 在android studio中填充float类型编辑文本的语音输入

我有一门课来计算体重指数。我想允许用户通过语音输入他/她的体重和身高。但是对于activityResult函数，我很困惑该如何做

public class BMIActivity extends AppCompatActivity {

//speech field
private static final int REQUEST_CODE_SPEECH_INPUT=1000;

//speech
TextView editText1;
TextView editText2;

//views for speech
FloatingActionButton mVoiceBtn;
TextView mVoiceInput;

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

    EditText weight,height;
    TextView txtRes,txtEnter;
    Button btnRes,btnReset;

    weight=findViewById(R.id.weight);
    height=findViewById(R.id.height);

    txtEnter= findViewById(R.id.txtEnter);
    txtRes= findViewById(R.id.txtRes);

    btnRes=findViewById(R.id.btnRes);
    btnReset=findViewById(R.id.btnReset);

    btnRes.setOnClickListener(new View.OnClickListener(){

        @Override
        public void onClick(View v) {
            String strweg=weight.getText().toString();
            String strhei=height.getText().toString();

            //hooks for shake detector
            editText1=(TextView) findViewById(R.id.weight);
            editText2=(TextView) findViewById(R.id.height);
            set_btn=findViewById(R.id.setBtn);

            //speech hooks
            mVoiceBtn = findViewById(R.id.voiceBtn);
            mVoiceInput = findViewById(R.id.voiceInput);

            if(strweg.equals("")){
                weight.setError("Please Enter Your Weight");
                weight.requestFocus();
                return;
            }
            if(strhei.equals("")){
                height.setError("Please Enter Your Height");
                height.requestFocus();
                return;
            }
            float wgt = Float.parseFloat(strweg);
            float hgt = Float.parseFloat(strhei)/100;

            float bmiValue = BMICalculate(wgt,hgt);

            txtEnter.setText(interpreteBMI(bmiValue));
            txtRes.setText("BMI = "+bmiValue);
        }
    });
    btnReset.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            height.setText("");
            weight.setText("");
            txtEnter.setText("");
            txtRes.setText("");
        }
    });

}

//在这里，我遇到了一个问题，通过单击麦克风按钮，允许用户首先通过语音输入重量，然后通过语音本身输入高度

  @Override
   protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    switch (requestCode) {
        case REQUEST_CODE_SPEECH_INPUT: {
            if (resultCode == RESULT_OK && null != data) {
                //get text array for voice intent
                ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
                mVoiceInput.setText(result.get(0));
                editText1.setText(result.get(0));

            }
            
            break;
        }
    }
}

public float BMICalculate(float weight, float height){
    return weight / (height*height);
}
public String interpreteBMI(float bmiValue){
    if(bmiValue<16){
        return "Severely underweight";
    }
    else if(bmiValue<18.5){
        return "Underweight";
    }
    else if(bmiValue<25){
        return "Normal";
    }
    else if(bmiValue<30){
        return "Overweight";
    }
    else{
        return "Obese";
    }
}
