Android懒人框架Android annotation

不知不觉有一个多月没更新了。唉，辞职了，最近一直在找工作没办法。蓝瘦。香菇。

annotation的配置

project的build.gradle

buildscript {    repositories {        jcenter()    }    dependencies {        classpath 'com.android.tools.build:gradle:1.5.0'        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'    }}allprojects {    repositories {        jcenter()    }}task clean(type: Delete) {    delete rootProject.buildDir}

moudle的build.gradle配置

apply plugin: 'com.android.application'apply plugin: 'android-apt'def AAVersion = '4.0+'repositories {    jcenter()    flatDir {        dirs 'libs'    }}android {    compileSdkVersion 19    buildToolsVersion "23.0.2"    defaultConfig {        applicationId "source.code.watch.film"        minSdkVersion 14        targetSdkVersion 14        versionCode 1        versionName "1.0"    }    buildTypes {        release {            minifyEnabled false            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'        }    }    signingConfigs {        debug {            storeFile file("E:\\psd\\debug.keystore")        }    }}dependencies {    compile fileTree(include: ['*.jar'], dir: 'libs')    apt "org.androidannotations:androidannotations:$AAVersion"    compile "org.androidannotations:androidannotations-api:$AAVersion"}apt {    arguments {        androidManifestFile variant.outputs[0].processResources.manifestFile        resourcePackageName 'source.code.watch.film'    }}

今天和大家介绍下Android的懒人框架：annotation。

@EActivity

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

@EFragment

@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" />

MyFragment fragment = new MyFragment_();

@EBean

public class MyClass {}- 这个类必须仅仅只能有一个构造函数，参数最多有一个context

@EActivity(R.layout.main)public class MyActivity extends Activity {  @Bean  MyClass myClass;}

@EActivity(R.layout.main)public class MyActivity extends Activity {  @Bean(MyClass.class)  MyClassInterface myClassInterface;}

@EBeanpublic class MyClass {  @RootContext  Context context;  @RootContext  Activity activity;  @RootContext  Service service;  @RootContext  MyActivity myActivity;}

@EActivity(R.layout.main)public class MyActivity extends Activity {  @AfterInject  public void doSomethingAfterInjection() {  }}- 如果想在类创建时期做一些操作可以这么做

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

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

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

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);  }}

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

@EAplication

@EApplicationpublic class MyApplication extends Application {}

@EActivity(R.layout.main)public class MyActivity extends Activity {  @App  MyApplication application;}

EService

@EServicepublic class MyService extends Service {}

MyService_.intent(getApplication()).start();

MyService_.intent(getApplication()).stop();

@EReceiver

@EReceiverpublic class MyReceiver extends BroadcastReceiver {}

@EActivity(R.layout.main)public class MyActivity extends Activity {  @Receiver(actions = "org.androidannotations.ACTION_1")  protected void onAction1() {  }}

@EProvider

@EProviderpublic class MyContentProvider extends ContentProvider {}

@EViewById

@EActivity(R.layout.main)public class MyActivity extends Activity {  @ViewById  EditText myEditText;  @ViewById(R.id.myTextView)  TextView textView;}- 没有括号里定义的变量名称必须和布局的id名称一致

@EAfterViews

@EActivity(R.layout.main)public class MyActivity extends Activity {   @ViewById   TextView myTextView;   @AfterViews   void updateTextWithDate() {      myTextView.setText("Date: " + new Date());   }} 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

@StringRes

@EActivity(R.layout.main)public class MyActivity extends Activity {   @StringRes(R.string.hello)   String myHelloString;   @StringRes   String hello;}- 不能将变量设置成私有变量

@ColorRes

@EActivity(R.layout.main)public class MyActivity extends Activity {  @ColorRes(R.color.backgroundColor)  int someColor;  @ColorRes  int backgroundColor;}

@AnimationRes

@EActivity(R.layout.main)public class MyActivity extends Activity {   @AnimationRes(R.anim.fadein)   XmlResourceParser xmlResAnim;   @AnimationRes   Animation fadein;}

@DimensionRes

@EActivity(R.layout.main)public class MyActivity extends Activity {  @DimensionRes(R.dimen.fontsize)  float fontSizeDimension;  @DimensionRes  float fontsize;}

@DimensionPixelOffsetRes

@EActivity(R.layout.main)public class MyActivity extends Activity {  @DimensionPixelOffsetRes(R.string.fontsize)  int fontSizeDimension;  @DimensionPixelOffsetRes  int fontsize;}

@DimensionPixelSizeRes

@EActivity(R.layout.main)public class MyActivity extends Activity {  @DimensionPixelSizeRes(R.string.fontsize)  int fontSizeDimension;  @DimensionPixelSizeRes  int fontsize;}

@Extra

@EActivity(R.layout.main)public class MyActivity extends Activity {  @Extra("myStringExtra")  String myMessage;  @Extra("myDateExtra")  Date myDateExtraWithDefaultValue = new Date();}

@EActivity(R.layout.main)public class MyActivity extends Activity {  @Extra  String myMessage;}- The name of the extra will be "myMessage"，名字必须一致

MyActivity_.intent().myMessage("hello").start() ;

MyActivity_.intent().myMessage("hello").startForResult() ;

@SystemService

@EActivity(R.layout.main)public class MyActivity extends Activity {  @SystemService  NotificationManager notificationManager;}

@HtmlRes

@EActivity(R.layout.main)public class MyActivity extends Activity {  @HtmlRes(R.string.hello_html)  Spanned myHelloString;  @HtmlRes  CharSequence helloHtml;}

@FromHtml

@EActivity(R.layout.main)public class MyActivity extends Activity {  @ViewById(R.id.my_text_view)  @FromHtml(R.string.hello_html)  TextView textView;  @ViewById  @FromHtml  TextView hello_html;}- 必须用在TextView

@NonConfigurationInstance

@EActivity(R.layout.main)public class MyActivity extends Activity {  @NonConfigurationInstance  Bitmap someBitmap;  @NonConfigurationInstance  @Bean  MyBackgroundTask myBackgroundTask;}- 等同于Activity.onRetainNonConfigurationInstance()

@Click

@Click(R.id.myButton)void myButtonWasClicked() {}@Clickvoid anotherButton() {}@Clickvoid yetAnotherButton(View clickedView) {}- LongClick和这个类似

@SeekBarProgressChange

@SeekBarProgressChange(R.id.seekBar) void onProgressChangeOnSeekBar(SeekBar seekBar, int progress, boolean fromUser) { } @SeekBarProgressChange(R.id.seekBar) void onProgressChangeOnSeekBar(SeekBar seekBar, int progress) { } @SeekBarProgressChange({R.id.seekBar1, R.id.seekBar2}) void onProgressChangeOnSeekBar(SeekBar seekBar) { } @SeekBarProgressChange({R.id.seekBar1, R.id.seekBar2}) void onProgressChangeOnSeekBar() { }- @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) { } @TextChange void helloTextViewTextChanged(TextView hello) { } @TextChange({R.id.editText, R.id.helloTextView}) void onTextChangesOnSomeTextViews(TextView tv, CharSequence text) { } @TextChange(R.id.helloTextView) void onTextChangesOnHelloTextView() { }

@BeforeTextChange

@BeforeTextChange(R.id.helloTextView) void beforeTextChangedOnHelloTextView(TextView hello, CharSequence text, int start, int count, int after) { } @BeforeTextChange void helloTextViewBeforeTextChanged(TextView hello) { } @BeforeTextChange({R.id.editText, R.id.helloTextView}) void beforeTextChangedOnSomeTextViews(TextView tv, CharSequence text) { } @BeforeTextChange(R.id.helloTextView) void beforeTextChangedOnHelloTextView() { }

@AfterTextChange

@AfterTextChange(R.id.helloTextView) void afterTextChangedOnHelloTextView(Editable text, TextView hello) { } @AfterTextChange void helloTextViewAfterTextChanged(TextView hello) { } @AfterTextChange({R.id.editText, R.id.helloTextView}) void afterTextChangedOnSomeTextViews(TextView tv, Editable text) { } @AfterTextChange(R.id.helloTextView) void afterTextChangedOnHelloTextView() { }

@Background

void myMethod() {    someBackgroundWork("hello", 42);}@Backgroundvoid someBackgroundWork(String aParam, long anotherParam) {}- 后台运行

void myMethod() {    someCancellableBackground("hello", 42);    boolean mayInterruptIfRunning = true;    BackgroundExecutor.cancelAll("cancellable_task", mayInterruptIfRunning);}@Background(id="cancellable_task")void someCancellableBackground(String aParam, long anotherParam) {}

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);}- 非并发执行

@Background(delay=2000)void doInBackgroundAfterTwoSeconds() {}- 延迟执行

@UIThread

void myMethod() {    doInUiThread("hello", 42);}@UiThreadvoid doInUiThread(String aParam, long anotherParam) {}- UI线程

@UiThread(delay=2000)void doInUiThreadAfterTwoSeconds() {}- 延迟

@UiThread(propagation = Propagation.REUSE)void runInSameThreadIfOnUiThread() {}- 优化UI线程

@EActivity(R.layout.main)public class MyActivity extends Activity {  @Background  void doSomeStuffInBackground() {    publishProgress(0);    publishProgress(10);    publishProgress(100);  }  @UiThread  void publishProgress(int progress) {  }}- 后台向UI线程传值

@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() {}

好了。关于annotation的介就是这么多。欢迎进群交流。还有，求工作啊！！！！
