Android 最火的高速开发框架androidannotations配置具体解释文章中有eclipse配置步骤，Android 最火高速开发框架AndroidAnnotations简介文章中的简介，本篇注重解说AndroidAnnotations中注解方法的使用。
@EActivity
演示样例：
@EActivity(R.layout.main)
public class MyActivity extends Activity {
}
演示样例：
注冊：@EFragment(R.layout.my_fragment_layout) public class MyFragment extends Fragment { }
<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 { }
Activity中使用：
@EActivity public class MyActivity extends Activity { @Bean MyOtherClass myOtherClass; }
也能够用来声明接口：
@Bean(MyImplementation.class) MyInterface myInterface;
在普通类中还能够注入根环境:
@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; }
假设想在类创建时期做一些操作能够：
@AfterInject public void doSomethingAfterInjection() { // notificationManager and dependency are set }
单例类须要例如以下声明：
@EBean(scope = Scope.Singleton) public class MySingleton { }
注意：在单例类里面不能够注入view和事件绑定，由于单例的生命周期比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); } }
注冊：
<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); } }
注冊：
<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
能够替代声明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，由于oncreate()在运行时 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; }
其它的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;
演示样例：
@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() {//假设不指定则函数名和id相应 [...] } @Click void yetAnotherButton(View clickedView) { [...] }
其它点击事件：
- Clicks with
@Click - Long clicks with
@LongClick - Touches with
@Touch
AdapterViewEvents
- Item clicks with
@ItemClick - Long item clicks with
@ItemLongClick - Item selection with
@ItemSelect
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 和 @SeekBarTouchStop
接受開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
运行：
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) { [...] }
非并发运行：
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() { }
以上的凝视使用方法基本包括了寻常程序中的事件绑定，用AndroidAnnotations框架能够专注于做逻辑开发，最主要是简化代码编写，easy维护。
