Android Studio中Java的if语句未生效问题求助

从TextView获取文本转换为数值后，第一个判断步数的if语句正常生效，但第二个判断卡路里与目标值大小的if语句完全没有反应。尝试将所有数值转为Integer类型后问题依旧，代码运行无报错。

初始化部分 #

public void getCurrentData() {
    TextView user = (TextView) getView().findViewById(R.id.global_text_username);
    String username = getActivity().getIntent().getStringExtra("email");
    String userId = username.substring(0, 5);
    user.setText(username);

    Drawable unreach = getResources().getDrawable(R.drawable.baseline_remove_circle_24, null);

    TextView user_current_cals = (TextView) getView().findViewById(R.id.home_text_calcode);
    TextView user_current_steps = (TextView) getView().findViewById(R.id.home_text_stepcode);
    TextView user_current_target = (TextView) getView().findViewById(R.id.home_text_targetcode);

    ImageView current_cals = (ImageView) getView().findViewById(R.id.home_img_calstatus);
    ImageView current_target = (ImageView) getView().findViewById(R.id.home_img_targetstatus);
    ImageView current_steps = (ImageView) getView().findViewById(R.id.home_img_stepstatus);

数值判断部分 #

String ucc = user_current_cals.getText().toString();
    double check_current_cals = Double.parseDouble(ucc);

    String uct = user_current_target.getText().toString();
    double check_current_target = Double.parseDouble(uct);

    String ucs = user_current_steps.getText().toString();
    int check_current_steps = Integer.parseInt(ucs);

    if (check_current_steps < 1000) {
        current_steps.setColorFilter(Color.argb(255, 244, 57, 57));
        current_steps.setImageDrawable(unreach);
    }

    if (check_current_cals < check_current_target) {
        current_cals.setColorFilter(Color.argb(255, 244, 57, 57));
        current_target.setColorFilter(Color.argb(255, 244, 57, 57));
        current_cals.setImageDrawable(unreach);
        current_target.setImageDrawable(unreach);
    }
}

排查方向 #

• 确认TextView的真实文本内容：转换数值前，输出ucc和uct的完整内容，检查是否包含空格、逗号、单位（如"kcal"）等非数字字符，这些会导致转换后的数值和视觉显示不符。
• 输出转换后的实际数值：在if语句前添加日志，查看check_current_cals和check_current_target的具体数值，确认两者的大小关系是否真的满足check_current_cals < check_current_target。示例代码：

  Log.d("CalCheck", "当前卡路里：" + check_current_cals + " | 目标卡路里：" + check_current_target);
  

• 检查后续代码的覆盖操作：确认是否有其他代码（如异步回调、生命周期方法）在这个if语句之后，修改了current_cals或current_target的Drawable/颜色滤镜，导致设置被覆盖。
• 验证ImageView的可修改性：将第二个if内的代码单独放到按钮点击事件中执行，确认ImageView是否能正常显示修改后的状态，排除控件或Drawable本身的问题。
• 添加数值转换的异常捕获：用try-catch包裹数值转换代码，避免TextView文本为空或非法时，转换失败导致数值异常（比如默认0），影响判断逻辑。示例：

  double check_current_cals = 0;
  try {
      String ucc = user_current_cals.getText().toString().trim();
      check_current_cals = Double.parseDouble(ucc);
  } catch (NumberFormatException e) {
      Log.e("CalError", "卡路里转换失败：" + e.getMessage());
  }
  
  double check_current_target = 0;
  try {
      String uct = user_current_target.getText().toString().trim();
      check_current_target = Double.parseDouble(uct);
  } catch (NumberFormatException e) {
      Log.e("TargetError", "目标值转换失败：" + e.getMessage());
  }
