    @EActivity

     示例:

    @EActivity(R.layout.main) public class MyActivity extends Activity { } @fragment

    示例:

    @EFragment(R.layout.my_fragment_layout) public class MyFragment extends Fragment { } 注册:

    <fragment android:id="@+id/myFragment" android:name="com.company.MyFragment_" android:layout_width="fill_parent" android:layout_height="fill_parent" />

    创建:

    MyFragment fragment = new MyFragment_();

    普通类:

    @EBean public class MyClass { }

    注意:这个类必须仅仅只能有一个构造函数,参数最多有一个context。

    Activity中使用:

    @EActivity public class MyActivity extends Activity { @Bean MyOtherClass myOtherClass; }

    也可以用来声明接口:

    @Bean(MyImplementation.class) MyInterface myInterface;

    在普通类中还可以注入根环境:

    @EBean public class MyClass { @RootContext Context context; // Only injected if the root context is an activity @RootContext Activity activity; // Only injected if the root context is a service @RootContext Service service; // Only injected if the root context is an instance of MyActivity @RootContext MyActivity myActivity; }

    如果想在类创建时期做一些操作可以:

    @AfterInject public void doSomethingAfterInjection() { // notificationManager and dependency are set }

    单例类需要如下声明:

    @EBean(scope = Scope.Singleton) public class MySingleton { }

    注意:在单例类里面不可以注入view和事件绑定,因为单例的生命周期比Activity和Service的要长,以免发生内存溢出。

    @EView

    @EView public class CustomButton extends Button { @App MyApplication application; @StringRes String someStringResource; public CustomButton(Context context, AttributeSet attrs) { super(context, attrs); } }

    注册:

    <com.androidannotations.view.CustomButton_ android:layout_width="match_parent" android:layout_height="wrap_content" />

    创建:

    CustomButton button = CustomButton_.build(context);

    @EViewGroup

    @EViewGroup(R.layout.title_with_subtitle) public class TitleWithSubtitle extends RelativeLayout { @ViewById protected TextView title, subtitle; public TitleWithSubtitle(Context context, AttributeSet attrs) { super(context, attrs); } public void setTexts(String titleText, String subTitleText) { title.setText(titleText); subtitle.setText(subTitleText); } }

    注册:

    <com.androidannotations.viewgroup.TitleWithSubtitle_ android:id="@+id/firstTitle" android:layout_width="match_parent" android:layout_height="wrap_content" />

    @EApplication

    @EApplication public class MyApplication extends Application { }

    Activity中使用: @EActivity public class MyActivity extends Activity { @App MyApplication application; } @EService @EService public class MyService extends Service { } 跳转service: MyService_.intent(getApplication()).start(); 停止service: MyService_.intent(getApplication()).stop(); @EReceiver @EReceiver public class MyReceiver extends BroadcastReceiver { } @Receiver 可以替代声明BroadcastReceiver @EActivity public class MyActivity extends Activity { @Receiver(actions = "org.androidannotations.ACTION_1") protected void onAction1() { } } @EProvider @EProvider public class MyContentProvider extends ContentProvider { } @ViewById @EActivity public class MyActivity extends Activity { // Injects R.id.myEditText,变量名称必须和布局的id名称一致 @ViewById EditText myEditText; @ViewById(R.id.myTextView) TextView textView; } @AfterViews @EActivity(R.layout.main) public class MyActivity extends Activity { @ViewById TextView myTextView; @AfterViews void updateTextWithDate() {//一定要在这里进行view的一些设置,不要在oncreate()中设置,因为oncreate()在执行时 view还没有注入 myTextView.setText("Date: " + new Date()); }[...] @StringRes @EActivity public class MyActivity extends Activity { @StringRes(R.string.hello) String myHelloString;//不能设置成私有变量 @StringRes String hello; } @ColorRes @EActivity public class MyActivity extends Activity { @ColorRes(R.color.backgroundColor) int someColor; @ColorRes int backgroundColor; } @AnimationRes @EActivity public class MyActivity extends Activity { @AnimationRes(R.anim.fadein) XmlResourceParser xmlResAnim; @AnimationRes Animation fadein; } @DimensionRes @EActivity public class MyActivity extends Activity { @DimensionRes(R.dimen.fontsize) float fontSizeDimension; @DimensionRes float fontsize; } @DImensionPixelOffsetRes @EActivity public class MyActivity extends Activity { @DimensionPixelOffsetRes(R.string.fontsize) int fontSizeDimension; @DimensionPixelOffsetRes int fontsize; } @DimensionPixelSizeRes @EActivity public class MyActivity extends Activity { @DimensionPixelSizeRes(R.string.fontsize) int fontSizeDimension; @DimensionPixelSizeRes int fontsize; } 其他的Res: @BooleanRes@ColorStateListRes@DrawableRes@IntArrayRes@IntegerRes@LayoutRes@MovieRes@TextRes@TextArrayRes@StringArrayRes @Extra @EActivity public class MyActivity extends Activity { @Extra("myStringExtra") String myMessage; @Extra("myDateExtra") Date myDateExtraWithDefaultValue = new Date(); } 或者: @EActivity public class MyActivity extends Activity { // The name of the extra will be "myMessage",名字必须一致 @Extra String myMessage; } 传值: MyActivity_.intent().myMessage("hello").start() ; @SystemService @EActivity public class MyActivity extends Activity {// @SystemService NotificationManager notificationManager; } @HtmlRes @EActivity public class MyActivity extends Activity { // Injects R.string.hello_html @HtmlRes(R.string.hello_html) Spanned myHelloString; // Also injects R.string.hello_html @HtmlRes CharSequence helloHtml; } @FromHtml @EActivity public class MyActivity extends Activity {//必须用在TextView @ViewById(R.id.my_text_view) @FromHtml(R.string.hello_html) TextView textView; // Injects R.string.hello_html into the R.id.hello_html view @ViewById @FromHtml TextView helloHtml; } @NonConfigurationInstance public class MyActivity extends Activity {//等同于 Activity.onRetainNonConfigurationInstance() @NonConfigurationInstance Bitmap someBitmap; @NonConfigurationInstance @Bean MyBackgroundTask myBackgroundTask; } @HttpsClient @HttpsClient HttpClient httpsClient; 示例: @EActivity public class MyActivity extends Activity { @HttpsClient(trustStore=R.raw.cacerts, trustStorePwd="changeit", hostnameVerif=true) HttpClient httpsClient; @AfterInject @Background public void securedRequest() { try { HttpGet httpget = new HttpGet("https://www.verisign.com/"); HttpResponse response = httpsClient.execute(httpget); doSomethingWithResponse(response); } catch (Exception e) { e.printStackTrace(); } } @UiThread public void doSomethingWithResponse(HttpResponse resp) { Toast.makeText(this, "HTTP status " + resp.getStatusLine().getStatusCode(), Toast.LENGTH_LONG).show(); } } @FragmentArg @EFragment public class MyFragment extends Fragment {//等同于 Fragment Argument @FragmentArg("myStringArgument") String myMessage; @FragmentArg String anotherStringArgument; @FragmentArg("myDateExtra") Date myDateArgumentWithDefaultValue = new Date(); } MyFragment myFragment = MyFragment_.builder() .myMessage("Hello") .anotherStringArgument("World") .build(); @Click @Click(R.id.myButton) void myButtonWasClicked() { [...] } @Click void anotherButton() {//如果不指定则函数名和id对应 [...] } @Click void yetAnotherButton(View clickedView) { [...] } 其他点击事件: Clicks with @ClickLong clicks with @LongClickTouches with @Touch

    AdapterViewEvents 

    Item clicks with @ItemClickLong item clicks with @ItemLongClickItem selection with @ItemSelect 有两种方式调用: 1. @EActivity(R.layout.my_list) public class MyListActivity extends Activity { // ... @ItemClick public void myListItemClicked(MyItem clickedItem) {//MyItem是adapter的实体类,等同于adapter.getItem(position) } @ItemLongClick public void myListItemLongClicked(MyItem clickedItem) { } @ItemSelect public void myListItemSelected(boolean selected, MyItem selectedItem) { } } 2. @EActivity(R.layout.my_list) public class MyListActivity extends Activity { // ... @ItemClick public void myListItemClicked(int position) {//位置id } @ItemLongClick public void myListItemLongClicked(int position) { } @ItemSelect public void myListItemSelected(boolean selected, int position) { } } @SeekBarProgressChange //等同于SeekBar.OnSeekBarChangeListener.onProgressChanged(SeekBar, int, boolean) @SeekBarProgressChange(R.id.seekBar) void onProgressChangeOnSeekBar(SeekBar seekBar, int progress, boolean fromUser) { // Something Here } @SeekBarProgressChange(R.id.seekBar) void onProgressChangeOnSeekBar(SeekBar seekBar, int progress) { // Something Here } @SeekBarProgressChange({R.id.seekBar1, R.id.seekBar2}) void onProgressChangeOnSeekBar(SeekBar seekBar) { // Something Here } @SeekBarProgressChange({R.id.seekBar1, R.id.seekBar2}) void onProgressChangeOnSeekBar() { // Something Here }@SeekBarTouchStart and @SeekBarTouchStop @SeekBarTouchStart 和 @SeekBarTouchStop 接受开始和结束事件的监听 @TextChange @TextChange(R.id.helloTextView) void onTextChangesOnHelloTextView(CharSequence text, TextView hello, int before, int start, int count) { // Something Here } @TextChange void helloTextViewTextChanged(TextView hello) { // Something Here } @TextChange({R.id.editText, R.id.helloTextView}) void onTextChangesOnSomeTextViews(TextView tv, CharSequence text) { // Something Here } @TextChange(R.id.helloTextView) void onTextChangesOnHelloTextView() { // Something Here } @BeforeTextChange @BeforeTextChange(R.id.helloTextView) void beforeTextChangedOnHelloTextView(TextView hello, CharSequence text, int start, int count, int after) { // Something Here } @BeforeTextChange void helloTextViewBeforeTextChanged(TextView hello) { // Something Here } @BeforeTextChange({R.id.editText, R.id.helloTextView}) void beforeTextChangedOnSomeTextViews(TextView tv, CharSequence text) { // Something Here } @BeforeTextChange(R.id.helloTextView) void beforeTextChangedOnHelloTextView() { // Something Here } @AfterTextChange @AfterTextChange(R.id.helloTextView) void afterTextChangedOnHelloTextView(Editable text, TextView hello) { // Something Here } @AfterTextChange void helloTextViewAfterTextChanged(TextView hello) { // Something Here } @AfterTextChange({R.id.editText, R.id.helloTextView}) void afterTextChangedOnSomeTextViews(TextView tv, Editable text) { // Something Here } @AfterTextChange(R.id.helloTextView) void afterTextChangedOnHelloTextView() { // Something Here } @OptionsMenu和OptionsItem @EActivity @OptionsMenu(R.menu.my_menu) public class MyActivity extends Activity { @OptionMenuItem MenuItem menuSearch; @OptionsItem(R.id.menuShare) void myMethod() { // You can specify the ID in the annotation, or use the naming convention } @OptionsItem void homeSelected() { // home was selected in the action bar // The "Selected" keyword is optional } @OptionsItem boolean menuSearch() { menuSearch.setVisible(false); // menuSearch was selected // the return type may be void or boolean (false to allow normal menu processing to proceed, true to consume it here) return true; } @OptionsItem({ R.id.menu_search, R.id.menu_delete }) void multipleMenuItems() { // You can specify multiple menu item IDs in @OptionsItem } @OptionsItem void menu_add(MenuItem item) { // You can add a MenuItem parameter to access it } } 或者: @EActivity @OptionsMenu({R.menu.my_menu1, R.menu.my_menu2}) public class MyActivity extends Activity { } @Background 执行: void myMethod() { someBackgroundWork("hello", 42); } @Background void someBackgroundWork(String aParam, long anotherParam) { [...] } 取消: void myMethod() { someCancellableBackground("hello", 42); [...] boolean mayInterruptIfRunning = true; BackgroundExecutor.cancelAll("cancellable_task", mayInterruptIfRunning); } @Background(id="cancellable_task") void someCancellableBackground(String aParam, long anotherParam) { [...] } 非并发执行: void myMethod() { for (int i = 0; i < 10; i++) someSequentialBackgroundMethod(i); } @Background(serial = "test") void someSequentialBackgroundMethod(int i) { SystemClock.sleep(new Random().nextInt(2000)+1000); Log.d("AA", "value : " + i); } 延迟: @Background(delay=2000) void doInBackgroundAfterTwoSeconds() { } @UiThread UI线程: void myMethod() { doInUiThread("hello", 42); } @UiThread void doInUiThread(String aParam, long anotherParam) { [...] } 延迟: @UiThread(delay=2000) void doInUiThreadAfterTwoSeconds() { } 优化UI线程: @UiThread(propagation = Propagation.REUSE) void runInSameThreadIfOnUiThread() { } 进度值改变: @EActivity public class MyActivity extends Activity { @Background void doSomeStuffInBackground() { publishProgress(0); // Do some stuff publishProgress(10); // Do some stuff publishProgress(100); } @UiThread void publishProgress(int progress) { // Update progress views } } @OnActivityResult @OnActivityResult(REQUEST_CODE) void onResult(int resultCode, Intent data) { } @OnActivityResult(REQUEST_CODE) void onResult(int resultCode) { } @OnActivityResult(ANOTHER_REQUEST_CODE) void onResult(Intent data) { } @OnActivityResult(ANOTHER_REQUEST_CODE) void onResult() { } 以上的注释用法基本包含了平常程序中的事件绑定,用AndroidAnnotations框架可以专注于做逻辑开发,最主要是简化代码编写,容易维护。 如有问题可以参考官方文档https://github.com/excilys/androidannotations/wiki/Cookbook, 转载出处:http://www.csdn123.com/html/topnews201408/29/729.htm
