禁用按钮，直到所有edittext字段都不为空并且逻辑满足为止

// 获取所有的edittext字段
EditText editText1 = findViewById(R.id.editText1);
EditText editText2 = findViewById(R.id.editText2);
EditText editText3 = findViewById(R.id.editText3);

// 监听文本变化事件
TextWatcher textWatcher = new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        // 检查所有edittext字段是否为空
        boolean isAllFieldsFilled = !editText1.getText().toString().isEmpty()
                && !editText2.getText().toString().isEmpty()
                && !editText3.getText().toString().isEmpty();

        // 检查其他逻辑条件是否满足
        boolean isLogicSatisfied = // 检查逻辑条件，例如验证输入格式等

        // 设置按钮状态
        Button button = findViewById(R.id.button);
        button.setEnabled(isAllFieldsFilled && isLogicSatisfied);
    }

    @Override
    public void afterTextChanged(Editable s) {
    }
};

// 为每个edittext字段添加文本变化监听器
editText1.addTextChangedListener(textWatcher);
editText2.addTextChangedListener(textWatcher);
editText3.addTextChangedListener(textWatcher);
