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 { }
@fragment
演示样例：
@EFragment(R.layout.my_fragment_layout)
public class MyFragment extends Fragment {
}
注冊：
<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：这个类必须只只能有一个构造函数，參数最多有一个context。
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 {
}
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
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 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。
