SupportAnnotation和AndroidAnnotations
截個圖,大概annotations 包中有40個註解,看名稱通常就知道是幹什麼的了, html
這個是 support-annotations-23.1.1 中的全部的註解, android
===================另一個開源的註解框架=================================git
這個開源的名稱是 androidannotations-api, 不是官方的,名字很像.
github
官方網站 : http://androidannotations.org/, 有個對比前,對比後, 效果很誘人,想試試.api
這裏是在Android Studiozhong的配置, 併發
http://blog.csdn.net/caiwenfeng_for_23/article/details/45801151app
有一些注意的就是, 對Activity的註解以後, 須要在Activity後面加上"_",清單中對Activity註冊也要加上"_"框架
而後就是被人吐槽的Rest Api ,應該只支持簡單的聯網處理, 複雜的用這個就不行了,dom
而後這裏還有一個出bug 的問題,ide

而後這兒有個一系列教程,2天了,終於找到一個系列了,這個至關詳細了:

而後,這個頁面包含了絕大部分註解的詳情:
http://www.csdn123.com/html/topnews201408/29/729.htm
粘貼過來:
@EActivity
@EActivity(R.layout.main)
public class MyActivity extends Activity {}
@fragment
@EFragment(R.layout.my_fragment_layout)
public class MyFragment extends Fragment {}
註冊：
<fragment android:id="@+id/myFragment" android:name="com.company.MyFragment_" android:layout_width="fill_parent" android:layout_height="fill_parent" />
建立：
MyFragment fragment = new MyFragment_();
@EBean
普通類：
@EBean
public class MyClass {}
注意：這個類必須僅僅只能有一個構造函數，參數最多有一個context。
Activity中使用：
@EActivity
public class MyActivity extends Activity {
@EBean
MyOtherClass myOtherClass;
}
也能夠用來聲明接口：
@EBean(MyImplementation.class) MyInterface myInterface;
@RootContext
在普通類中還能夠注入根環境:
@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;
}
@AfterInject
若是想在類建立時期作一些操做能夠：
@AfterInject
public void doSomethingAfterInjection() {
// notificationManager and dependency are set
}
scope
單例類須要以下聲明：
@EBean(scope = Scope.Singleton)
public class MySingleton {}
注意：在單例類裏面不能夠注入view和事件綁定，由於單例的生命週期比Activity和Service的要長，以避免發生內存溢出。
@EView
@EViewpublic class CustomButton extends Button {
@App
MyApplication application;
@StringRes
String someStringResource;
public CustomButton(Context context, AttributeSet attrs) {
super(context, attrs);
}}
註冊：
<com.androidannotations.view.CustomButton_ android:layout_width="match_parent" android:layout_height="wrap_content" />
建立：
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);
}
}
註冊：
<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
@EServicepublic class MyService extends Service {}
跳轉service：
MyService_.intent(getApplication()).start();
中止service：
MyService_.intent(getApplication()).stop();
@EReceiver
@EReceiverpublic class MyReceiver extends BroadcastReceiver {}
@Receiver
能夠替代聲明BroadcastReceiver
@EActivitypublic class MyActivity extends Activity {
@Receiver(actions = "org.androidannotations.ACTION_1")
protected void onAction1() {
}}
@EProvider
@EProviderpublic class MyContentProvider extends ContentProvider {}
@ViewById
@EActivitypublic class MyActivity extends Activity {
// Injects R.id.myEditText，變量名稱必須和佈局的id名稱一致
@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() {//必定要在這裏進行view的一些設置，不要在oncreate()中設置，由於oncreate()在執行時 view尚未注入 myTextView.setText("Date: " + new Date()); }[...]
@StringRes
@EActivitypublic class MyActivity extends Activity {
@StringRes(R.string.hello)
String myHelloString;//不能設置成私有變量
@StringRes
String hello;}
@ColorRes
@EActivitypublic class MyActivity extends Activity {
@ColorRes(R.color.backgroundColor)
int someColor;
@ColorRes
int backgroundColor;}
@AnimationRes
@EActivitypublic class MyActivity extends Activity {
@AnimationRes(R.anim.fadein)
XmlResourceParser xmlResAnim;
@AnimationRes
Animation fadein;}
@DimensionRes
@EActivitypublic class MyActivity extends Activity {
@DimensionRes(R.dimen.fontsize)
float fontSizeDimension;
@DimensionRes
float fontsize;}
@DImensionPixelOffsetRes
@EActivitypublic class MyActivity extends Activity {
@DimensionPixelOffsetRes(R.string.fontsize)
int fontSizeDimension;
@DimensionPixelOffsetRes
int fontsize;}
@DimensionPixelSizeRes
@EActivitypublic class MyActivity extends Activity {
@DimensionPixelSizeRes(R.string.fontsize)
int fontSizeDimension;
@DimensionPixelSizeRes
int fontsize;}
其餘的Res：
@BooleanRes@ColorStateListRes@DrawableRes@IntArrayRes@IntegerRes@LayoutRes@MovieRes@TextRes@TextArrayRes@StringArrayRes
@Extra
@EActivitypublic 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"，名字必須一致
@Extra
String myMessage;}
傳值：
MyActivity_.intent().myMessage("hello").start() ;
@SystemService
@EActivitypublic class MyActivity extends Activity {//
@SystemService
NotificationManager notificationManager;}
@HtmlRes
@EActivitypublic 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 {//必須用在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 {//等同於 Activity.onRetainNonConfigurationInstance()
@NonConfigurationInstance
Bitmap someBitmap;
@NonConfigurationInstance
@Bean
MyBackgroundTask myBackgroundTask;}
@HttpsClient
@HttpsClientHttpClient 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
@EFragmentpublic class MyFragment extends Fragment {//等同於 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() {
[...]}@Clickvoid anotherButton() {//若是不指定則函數名和id對應
[...]}@Clickvoid yetAnotherButton(View clickedView) {
[...]}
其餘點擊事件：
Clicks with
@ClickLong clicks with
@LongClickTouches with
@Touch
AdapterViewEvents
Item clicks with
@ItemClickLong item clicks with
@ItemLongClickItem selection with
@ItemSelect
有兩種方式調用：
1.
@EActivity(R.layout.my_list)public class MyListActivity extends Activity {
// ...
@ItemClick
public void myListItemClicked(MyItem clickedItem) {//MyItem是adapter的實體類，等同於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
//等同於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
接受開始和結束事件的監聽
@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
}

@BeforeTextChange(R.id.helloTextView)
void beforeTextChangedOnHelloTextView(TextView hello, CharSequence text, int start, int count, int after) {
// Something Here
}
@BeforeTextChange
void helloTextViewBeforeTextChanged(TextView hello) {

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
執行：
void myMethod() {
someBackgroundWork("hello", 42);}@Backgroundvoid 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) {
[...]}
非併發執行：
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);}
延遲：
@Background(delay=2000)void doInBackgroundAfterTwoSeconds() {}
@UiThread
UI線程：
void myMethod() {
doInUiThread("hello", 42);}@UiThreadvoid doInUiThread(String aParam, long anotherParam) {
[...]}
延遲：
@UiThread(delay=2000)void doInUiThreadAfterTwoSeconds() {}
優化UI線程：
@UiThread(propagation = Propagation.REUSE)void runInSameThreadIfOnUiThread() {}
進度值改變：
@EActivitypublic 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() {
}
以上的註釋用法基本包含了日常程序中的事件綁定，用AndroidAnnotations框架能夠專一於作邏輯開發，最主要是簡化代碼編寫，容易維護。
