猜拳小游戏采用比较笨的方法编写比较电脑跟玩家出的拳。

在其中添加了Menu组件。

具体代码如下：

Mainactivity类代码：

public class MainActivity extends Activity {private Button clickButton;private RadioGroup sexGroup;private RadioButton op1;private RadioButton op2;private RadioButton op3;String chu;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);initComponnents();clickButton.setOnClickListener(new ClickHandler());sexGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {@Overridepublic void onCheckedChanged(RadioGroup group, int checkedId) {if (checkedId == op1.getId()) {chu = "石头";}else if (checkedId == op2.getId()) {chu = "剪刀";} else if (checkedId == op3.getId()) {chu = "布";}}});}private void initComponnents() {sexGroup = (RadioGroup) findViewById(R.id.op);clickButton = (Button) this.findViewById(R.id.Button);op1 = (RadioButton) findViewById(R.id.shitou);op2 = (RadioButton) findViewById(R.id.jiandao);op3 = (RadioButton) findViewById(R.id.bu);}private class ClickHandler implements OnClickListener {@Overridepublic void onClick(View v) {Intent intent = new Intent();intent.setClass(MainActivity.this, showActivity.class);intent.putExtra("chu", chu);System.out.println(chu);startActivity(intent);finish();}}public boolean onCreateOptionsMenu(Menu menu) {getMenuInflater().inflate(R.menu.main, menu);return true;}public boolean onOptionsItemSelected(MenuItem item) {int item_id = item.getItemId();switch (item_id) {case R.id.about:AlertDialog.Builder builder = new AlertDialog.Builder(this);builder.setTitle(R.string.ok).setMessage("猜拳小游戏\n作者:xxx").setPositiveButton("确定", null).create().show();break;case R.id.exit:finish();break;}return true;}}

showActivity代码如下：

public class showActivity extends Activity {private TextView op1;private TextView op2;private TextView result;protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main2);initComponnents();// 电脑随机产生0.1.2并赋值为aString[] readomWord = { "0", "1", "2" };int readomWordIndex = (int) (Math.random() * 3);String a = readomWord[readomWordIndex];System.out.println(a);// 显示电脑出的,0表示石头，1表示剪刀，2表示布。if (a.equals("0")) {op1.setText("石头");}if (a.equals("1")) {op1.setText("剪刀");}if (a.equals("2")) {op1.setText("布");}Intent intent=new Intent();intent=this.getIntent();String n=intent.getStringExtra("chu");//显示玩家出的拳：if (n.equals("石头")) {op2.setText("石头");}if (n.equals("剪刀")) {op2.setText("剪刀");}if (n.equals("布")) {op2.setText("布");}//判断输赢if(a.equals("0")&&n.equals("剪刀")){result.setText("电脑获胜！");}else if(a.equals("1")&&n.equals("布")){result.setText("电脑获胜！");}else if(a.equals("2")&&n.equals("石头")){result.setText("电脑获胜！");}else if(a.equals("1")&&n.equals("石头")){result.setText("玩家获胜！");}else if(a.equals("0")&&n.equals("布")){result.setText("玩家获胜！");}else if(a.equals("2")&&n.equals("剪刀")){result.setText("玩家获胜！");}else {result.setText("平局");}}private void initComponnents() {op1 = (TextView) findViewById(R.id.op1);op2 = (TextView) findViewById(R.id.op2);result = (TextView) findViewById(R.id.result);}public boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.main1, menu);return true;}public boolean onOptionsItemSelected(MenuItem item) {int item_id = item.getItemId();switch (item_id) {case R.id.about:AlertDialog.Builder builder = new AlertDialog.Builder(this);builder.setTitle(R.string.ok).setMessage("猜拳小游戏\n作者:xxx").setPositiveButton("确定", null).create().show();break;case R.id.exit:Intent intent =new Intent();intent.setClass(this, MainActivity.class);startActivity(intent);finish();break;}return true;}}

关于Menu类：

public class Activity02 extends Activity {public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);}public boolean onCreateOptionsMenu(Menu menu){menu.add(0,0,0,R.string.ok);menu.add(0,1,1,R.string.back);return true;}public boolean onOptionsItemSelected(MenuItem item){int item_id=item.getItemId();switch(item_id){case 0:case 1:Intent intent =new Intent();intent.setClass(Activity02.this,MainActivity.class);startActivity(intent);finish();break;}return true;}}

布局文件：

activity_main：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context=".MainActivity" >    <TextView        android:id="@+id/textView1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="@string/hello_world" />    <RadioGroup        android:id="@+id/op"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_marginTop="16dp"        android:orientation="horizontal" >        <RadioButton            android:id="@+id/shitou"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_gravity="center_horizontal"            android:layout_marginTop="16dp"            android:text="@string/shitou" />        <RadioButton            android:id="@+id/bu"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_marginRight="16dp"            android:text="@string/bu" />        <RadioButton            android:id="@+id/jiandao"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_gravity="center_horizontal"            android:text="@string/jiandao" />    </RadioGroup>    <Button        android:id="@+id/Button"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="@string/chuquan" /></LinearLayout>

activity_main2:
