实现功能：总共分三个模式普通模式：数字0-100 困难模式：数字0-1000 地狱模式：数字0-10000 输入数字，会提示大还是小，猜对了，三种提示，还会有猜测数字显示

MainActivity.java代码如下：

public class MainActivity extends AppCompatActivity { private Button General,Diffculty,Hell; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); InitView(); Listener(); } private void InitView(){ General = findViewById(R.id.general); Diffculty = findViewById(R.id.difficulty); Hell = findViewById(R.id.hell); } private void Listener(){ OnClick onClick = new OnClick(); General.setOnClickListener(onClick); Diffculty.setOnClickListener(onClick); Hell.setOnClickListener(onClick); } private class OnClick implements View.OnClickListener{ @Override public void onClick(View v) { Intent intent = null; switch (v.getId()){ case R.id.general: intent = new Intent(MainActivity.this,General.class); break; case R.id.difficulty: intent = new Intent(MainActivity.this,Difficulty.class); break; case R.id.hell: intent = new Intent(MainActivity.this,Hell.class); break; } startActivity(intent); } } }

activity_main.xml:效果图如下： activity_main.xml:代码如下：

建立三个活动分别为General，Difficulty，Hell,由于代码相似，只展示普通模式的代码，其余俩只更改随机函数中的数值范围即可 General.java代码如下:

public class General extends AppCompatActivity { private EditText Number; private Button Submit; private TextView GuessNumberResult, GuessNumberTimes; private int intGuessNumber = 0; private int NumberOfGuesses = 0; private int RandomNumber = 0; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_general); Number = findViewById(R.id.Number); Submit = findViewById(R.id.submit); GuessNumberResult = findViewById(R.id.GuessNumberResult); GuessNumberTimes = findViewById(R.id.GuessNumberTimes); RandomNumber = (int) (Math.random()*(100-1+1)); Submit.setOnClickListener(new View.OnClickListener() { @Override public void onClick(final View v) { String StrGuessNumber = Number.getText().toString(); try{ intGuessNumber = Integer.parseInt(StrGuessNumber); }catch (NumberFormatException e) { e.printStackTrace(); } if (intGuessNumber < RandomNumber ) { NumberOfGuesses++; GuessNumberResult.setVisibility(View.VISIBLE); GuessNumberTimes.setVisibility(View.VISIBLE); GuessNumberResult.setText("猜的数字偏小"); GuessNumberTimes.setText("猜测次数："+NumberOfGuesses); } if (intGuessNumber > RandomNumber ) { NumberOfGuesses++; GuessNumberResult.setVisibility(View.VISIBLE); GuessNumberTimes.setVisibility(View.VISIBLE); GuessNumberResult.setText("猜的数字偏大"); GuessNumberTimes.setText("猜测次数："+NumberOfGuesses); } if (intGuessNumber == RandomNumber ) { NumberOfGuesses++; GuessNumberResult.setVisibility(View.VISIBLE); GuessNumberTimes.setVisibility(View.VISIBLE); GuessNumberResult.setText("恭喜你，猜对了"); GuessNumberTimes.setText("猜测次数："+NumberOfGuesses); } } }); } }

activity_general.xml代码如下：
