在Android studio编程完成以下需求,并给出详细代码和文件名:要求实现一个猜词游戏。 1) 应用在词库选取一个单词(单词长度不得大于 5 个字符),向用户显示相应数量的 下划线和一个绞刑架。 2) 用户输入一个字母。如果该字母在单词中,则该字母所在的所有位置的下划线被替 换为字母。如果该字母不在单词中,则绞刑架上的小人添加一笔。 3) 如果用户在绞刑架的小人画完整前猜对所有字母,游戏成功。如果绞刑架的小人画 完整(一共七笔)时没有猜对所有字母,游戏失败。 4) 游戏结果通过对话框告知用户,并询问用户退出游戏还是进行新一轮游戏。

好的,这是一个完整的Android Studio项目,包含了你所需的所有代码和文件。
在项目中,我们将创建一个名为“Hangman”的应用程序,它将允许用户玩猜词游戏。以下是步骤:
1. 创建一个新的Android Studio项目,并将应用程序命名为“Hangman”。
2. 在MainActivity.java文件中,我们将定义所有的游戏逻辑和UI。
MainActivity.java代码如下:
```
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;
import androidx.appcompat.app.AppCompatActivity;
import java.util.Arrays;
import java.util.List;
import java.util.Random;
public class MainActivity extends AppCompatActivity {
private ImageView hangmanImage;
private TextView wordTextView;
private EditText letterEditText;
private Button submitButton;
private int wrongGuesses = 0;
private String wordToGuess;
private char[] currentWordState;
private boolean gameFinished = false;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
hangmanImage = findViewById(R.id.hangman_image);
wordTextView = findViewById(R.id.word_text_view);
letterEditText = findViewById(R.id.letter_edit_text);
submitButton = findViewById(R.id.submit_button);
submitButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (!gameFinished) {
String letter = letterEditText.getText().toString();
if (letter.length() == 1) {
checkLetter(letter.charAt(0));
letterEditText.setText("");
} else {
Toast.makeText(MainActivity.this, "Please enter a single letter", Toast.LENGTH_SHORT).show();
}
} else {
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("Game Over");
builder.setMessage("Do you want to play again?");
builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
resetGame();
}
});
builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
finish();
}
});
builder.show();
}
}
});
resetGame();
}
private void resetGame() {
List<String> words = Arrays.asList("hang", "mate", "code", "java", "test");
Random random = new Random();
wordToGuess = words.get(random.nextInt(words.size()));
currentWordState = new char[wordToGuess.length()];
Arrays.fill(currentWordState, '_');
wordTextView.setText(String.valueOf(currentWordState));
hangmanImage.setImageResource(R.drawable.hangman_0);
wrongGuesses = 0;
gameFinished = false;
}
private void checkLetter(char letter) {
boolean letterFound = false;
for (int i = 0; i < wordToGuess.length(); i++) {
if (wordToGuess.charAt(i) == letter) {
currentWordState[i] = letter;
letterFound = true;
}
}
if (!letterFound) {
wrongGuesses++;
int hangmanImageResource = getResources().getIdentifier("hangman_" + wrongGuesses, "drawable", getPackageName());
hangmanImage.setImageResource(hangmanImageResource);
}
wordTextView.setText(String.valueOf(currentWordState));
if (Arrays.equals(currentWordState, wordToGuess.toCharArray())) {
gameFinished = true;
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("Congratulations");
builder.setMessage("You won! Do you want to play again?");
builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
resetGame();
}
});
builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
finish();
}
});
builder.show();
} else if (wrongGuesses == 7) {
gameFinished = true;
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("Game Over");
builder.setMessage("You lost! Do you want to play again?");
builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
resetGame();
}
});
builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
finish();
}
});
builder.show();
}
}
}
```
3. 在res/layout文件夹中创建一个名为“activity_main.xml”的新布局文件,用于定义应用程序的UI元素。
activity_main.xml代码如下:
```
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="16dp"
tools:context=".MainActivity">
<TextView
android:id="@+id/word_text_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="24sp"
android:textStyle="bold"
android:layout_gravity="center_horizontal"
android:layout_marginBottom="16dp"/>
<ImageView
android:id="@+id/hangman_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/hangman_0"
android:layout_gravity="center_horizontal"
android:layout_marginBottom="16dp"/>
<EditText
android:id="@+id/letter_edit_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="text"
android:maxLength="1"
android:hint="Enter a letter"
android:layout_marginBottom="16dp"/>
<Button
android:id="@+id/submit_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Submit"
android:layout_gravity="center_horizontal"/>
</LinearLayout>
```
4. 在res/drawable文件夹中创建一个名为“hangman_0.png”的新图像文件,这将是游戏的初始绞刑架图像。然后,创建另外6个名为“hangman_1.png”到“hangman_6.png”的图像文件,这些图像将在用户猜错字母时显示。
现在,你可以运行应用程序并开始玩猜词游戏了!
