实现的功能包括：数字输入、加减乘除运算、清空、计算结果等。值得注意的是，由于本代码没有考虑到浮点数运算，因此不能处理小数的计算。同时，也没有为界面添加其他的功能和效果。如需更加全面的实现，还需要进行进一步的改进。

### 回答3：
Android Studio 计算器界面是使用 Java 编写的。在这个项目中，你需要使用 Java 编写一个能够实现基本加减乘除运算的计算器界面。以下是一个简单的示例代码：

MainActivity.java

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

private EditText mCalculationResultEditText;
private String mCalculationResult;
private Button mButtonZero, mButtonOne, mButtonTwo, mButtonThree, mButtonFour, mButtonFive, mButtonSix, mButtonSeven, mButtonEight, mButtonNine, mButtonAdd, mButtonSubtract, mButtonMultiply, mButtonDivide, mButtonDecimal, mButtonEquals, mButtonClear;

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

mCalculationResultEditText = (EditText) findViewById(R.id.result_edit_text);

mButtonZero = (Button) findViewById(R.id.button_zero);
mButtonOne = (Button) findViewById(R.id.button_one);
mButtonTwo = (Button) findViewById(R.id.button_two);
mButtonThree = (Button) findViewById(R.id.button_three);
mButtonFour = (Button) findViewById(R.id.button_four);
mButtonFive = (Button) findViewById(R.id.button_five);
mButtonSix = (Button) findViewById(R.id.button_six);
mButtonSeven = (Button) findViewById(R.id.button_seven);
mButtonEight = (Button) findViewById(R.id.button_eight);
mButtonNine = (Button) findViewById(R.id.button_nine);
mButtonAdd = (Button) findViewById(R.id.button_add);
mButtonSubtract = (Button) findViewById(R.id.button_subtract);
mButtonMultiply = (Button) findViewById(R.id.button_multiply);
mButtonDivide = (Button) findViewById(R.id.button_divide);
mButtonDecimal = (Button) findViewById(R.id.button_decimal);
mButtonEquals = (Button) findViewById(R.id.button_equals);
mButtonClear = (Button) findViewById(R.id.button_clear);

mButtonZero.setOnClickListener(this);
mButtonOne.setOnClickListener(this);
mButtonTwo.setOnClickListener(this);
mButtonThree.setOnClickListener(this);
mButtonFour.setOnClickListener(this);
mButtonFive.setOnClickListener(this);
mButtonSix.setOnClickListener(this);
mButtonSeven.setOnClickListener(this);
mButtonEight.setOnClickListener(this);
mButtonNine.setOnClickListener(this);
mButtonAdd.setOnClickListener(this);
mButtonSubtract.setOnClickListener(this);
mButtonMultiply.setOnClickListener(this);
mButtonDivide.setOnClickListener(this);
mButtonDecimal.setOnClickListener(this);
mButtonEquals.setOnClickListener(this);
mButtonClear.setOnClickListener(this);
}

@Override
public void onClick(View v) {

switch (v.getId()) {

case R.id.button_zero:
mCalculationResultEditText.append("0");
break;
case R.id.button_one:
mCalculationResultEditText.append("1");
break;
case R.id.button_two:
mCalculationResultEditText.append("2");
break;
case R.id.button_three:
mCalculationResultEditText.append("3");
break;
case R.id.button_four:
mCalculationResultEditText.append("4");
break;
case R.id.button_five:
mCalculationResultEditText.append("5");
break;
case R.id.button_six:
mCalculationResultEditText.append("6");
break;
case R.id.button_seven:
mCalculationResultEditText.append("7");
break;
case R.id.button_eight:
mCalculationResultEditText.append("8");
break;
case R.id.button_nine:
mCalculationResultEditText.append("9");
break;
case R.id.button_add:
mCalculationResultEditText.append("+");
break;
case R.id.button_subtract:
mCalculationResultEditText.append("-");
break;
case R.id.button_multiply:
mCalculationResultEditText.append("*");
break;
case R.id.button_divide:
mCalculationResultEditText.append("/");
break;
case R.id.button_decimal:
mCalculationResultEditText.append(".");
break;
case R.id.button_equals:
mCalculationResult = mCalculationResultEditText.getText().toString();
double result = calculateResult(mCalculationResult);
mCalculationResultEditText.setText(String.valueOf(result));
break;
case R.id.button_clear:
mCalculationResultEditText.setText("");
break;
}
}

private double calculateResult(String calculationString) {
double result = 0.0;
try {
ScriptEngineManager mgr = new ScriptEngineManager();
ScriptEngine engine = mgr.getEngineByName("js");
result = (double)engine.eval(calculationString);
} catch (ScriptException e) {
e.printStackTrace();
}
return result;
}
}

以上代码实现了一个简单的计算器，按钮响应事件使用了 OnClickListener 接口。其中 ScriptEngineManager 和 ScriptEngine 可以方便地实现计算功能。当用户点击等号时，获取 EditText 中的文本并计算结果，将计算结果显示在 EditText 中。当用户点击 Clear 按钮时，清除 EditText 中的文本。
