该项目实现的功能主要有
在首页显示一个按钮点击该按钮跳转到桃园页面在桃园页面点击桃子会弹窗显示摘到几个桃子同时被点击桃子消失总桃子数1点击退出桃园会返回首页首页桃子数会根据点击的桃子数动态增加
二、代码实现
1. 资源准备
将项目所需要的图片bg.png、monkey.png、btn_peach.png、peach_pic.png 导入程序的drawablehdpi文件夹中默认情况下程序中没有drawable-hdpi 文件夹需手动在res 文件夹中创建一个。
2. 布局文件设计
2.1 主Activity
在layout文件夹中编辑activity_main.xml
?xml version1.0 encodingutf-8?
LinearLayout xmlns:androidhttp://schemas.android.com/apk/res/androidandroid:layout_widthmatch_parentandroid:layout_heightmatch_parentandroid:orientationverticalTextViewandroid:layout_widthmatch_parentandroid:layout_height50dpandroid:background#008577android:gravitycenterandroid:text首页android:textColorandroid:color/whiteandroid:textSize20sp /RelativeLayoutandroid:layout_widthmatch_parentandroid:layout_heightmatch_parentandroid:backgrounddrawable/bgandroid:gravitycenter_verticalImageViewandroid:idid/iv_monkeyandroid:layout_widthwrap_contentandroid:layout_heightwrap_contentandroid:srcdrawable/monkey /Buttonandroid:idid/btn_peachandroid:layout_width80dpandroid:layout_height40dpandroid:layout_marginLeft30dpandroid:layout_marginTop250dpandroid:layout_toRightOfid/iv_monkeyandroid:backgrounddrawable/btn_peachandroid:gravitycenterandroid:text去桃园android:textColorandroid:color/blackandroid:textSize18sp /ImageViewandroid:idid/iv_peachandroid:layout_width45dpandroid:layout_height35dpandroid:layout_belowid/btn_peachandroid:layout_centerHorizontaltrueandroid:layout_marginTop20dpandroid:srcdrawable/peach_pic /TextViewandroid:idid/tv_countandroid:layout_widthwrap_contentandroid:layout_heightwrap_contentandroid:layout_belowid/btn_peachandroid:layout_marginTop25dpandroid:layout_marginLeft10dpandroid:layout_toRightOfid/iv_peachandroid:text摘到0 个android:textColorandroid:color/blackandroid:textSize20sp //RelativeLayout
/LinearLayout2.2 辅Activity
在layout文件夹中新增activity_peach.xml
?xml version1.0 encodingutf-8?

/resources3. 实现逻辑功能
3.0 全局配置文件
?xml version1.0 encodingutf-8?
manifest xmlns:androidhttp://schemas.android.com/apk/res/androidpackagecom.hzj.pickpeachapplicationandroid:allowBackuptrueandroid:iconmipmap/ic_launcherandroid:labelstring/app_nameandroid:roundIconmipmap/ic_launcher_roundandroid:supportsRtltrueandroid:themestyle/MyCustomThemeactivityandroid:name.MainActivityandroid:exportedtrueintent-filteraction android:nameandroid.intent.action.MAIN /category android:nameandroid.intent.category.LAUNCHER //intent-filter/activityactivityandroid:name.PeachActivityandroid:exportedtrue/activity/application/manifest3.1 首页功能 在MainActivity 中实现“去桃园”按钮的点击事件当点击按钮时程序跳转到桃园摘桃的界面。同时还需要接收桃园界面回传过来的桃子个数。 public class MainActivity extends AppCompatActivity {private Button btn_peach;private TextView tv_count;private int totalCount 0;Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);init();}private void init() {btn_peach findViewById(R.id.btn_peach);tv_count findViewById(R.id.tv_count);//为按钮设置点击事件监听器btn_peach.setOnClickListener(new View.OnClickListener() {Overridepublic void onClick(View view) {//设置意图对象实现界面跳转Intent intent new Intent(MainActivity.this, PeachActivity.class);startActivityForResult(intent, 1);
// startActivity(intent);}});}Overrideprotected void onActivityResult(int requestCode, int resultCode, Nullable Intent data) {super.onActivityResult(requestCode, resultCode, data);//判断请求码和返回码是否正确if (requestCode1 requestCode1) {//获取回传的数据int count data.getIntExtra(count, 0);;totalCount totalCount count;tv_count.setText(摘到 totalCount 个);}}
}3.2 桃园界面的摘桃效果 点击桃子实现摘桃效果同时全局桃子数动态变化点击退出桃园返回首页同时更新首页桃子数。 public class PeachActivity extends AppCompatActivity implements View.OnClickListener {private Button btn_one, btn_two, btn_three, btn_four, btn_five, btn_six, btn_exit;private int count 0;//桃子个数Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_peach);init();}private void init() {btn_one findViewById(R.id.btn_one);btn_two findViewById(R.id.btn_two);btn_three findViewById(R.id.btn_three);btn_four findViewById(R.id.btn_four);btn_five findViewById(R.id.btn_five);btn_six findViewById(R.id.btn_six);btn_exit findViewById(R.id.btn_exit);btn_one.setOnClickListener(this);btn_two.setOnClickListener(this);btn_three.setOnClickListener(this);btn_four.setOnClickListener(this);btn_five.setOnClickListener(this);btn_six.setOnClickListener(this);btn_exit.setOnClickListener(this);}Overridepublic void onClick(View view) {switch (view.getId()) {case R.id.btn_one: //第一个桃子的点击事件info(btn_one);break;case R.id.btn_two: //第二个桃子的点击事件info(btn_two);break;case R.id.btn_three: //第三个桃子的点击事件info(btn_three);break;case R.id.btn_four: //第四个桃子的点击事件info(btn_four);break;case R.id.btn_five: //第五个桃子的点击事件info(btn_five);break;case R.id.btn_six: //第六个桃子的点击事件info(btn_six);break;case R.id.btn_exit: //“退出桃园”按钮的点击事件returnData();break;default:throw new IllegalStateException(Unexpected value: view.getId());}}/*** 按钮的点击事件处理*/private void info(Button btn) {//桃子个数加1count;//被摘掉的桃子设置为隐藏不可见btn.setVisibility(View.INVISIBLE);Toast.makeText(PeachActivity.this, 摘到 count 个桃子,Toast.LENGTH_LONG).show();}/*** 将数据回传到上个界面*/private void returnData() {//设置意图对象将摘桃子的个数回传给首页界面Intent intent new Intent();intent.putExtra(count, count);//返回码标识setResult(1, intent);//销毁本界面PeachActivity.this.finish();}Overridepublic boolean onKeyDown(int keyCode, KeyEvent event) {//当点击设备返回键时调用数据回传方法返回首页界面if (keyCode KeyEvent.KEYCODE_BACK event.getRepeatCount() 0) {returnData();}return false;}
