Android 最火的快速開發框架androidannotations配置詳解文章中有eclipse配置步驟,Android 最火快速開發框架AndroidAnnotations簡介文章中的簡單介紹,本篇注重講解AndroidAnnotations中注解方法的使用。
@EActivity
示例:
@EActivity(R.layout.main) public class MyActivity extends Activity { }@fragment
示例:
注冊:@EFragment(R.layout.my_fragment_layout) public class MyFragment extends Fragment { }
創建:
MyFragment fragment = new MyFragment_();
普通類:
@EBean public class MyClass { }
Activity中使用:
@EActivity public class MyActivity extends Activity { @Bean MyOtherClass myOtherClass; }
也可以用來聲明接口:
@Bean(MyImplementation.class) MyInterface myInterface;
在普通類中還可以注入根環境:
@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; }
如果想在類創建時期做一些操作可以:
@AfterInject public void doSomethingAfterInjection() { // notificationManager and dependency are set }
單例類需要如下聲明:
@EBean(scope = Scope.Singleton) public class MySingleton { }
注意:在單例類裡面不可以注入view和事件綁定,因為單例的生命周期比Activity和Service的要長,以免發生內存溢出。
@EView
@EView public class CustomButton extends Button { @App MyApplication application; @StringRes String someStringResource; public CustomButton(Context context, AttributeSet attrs) { super(context, attrs); } }
注冊:
創建:
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:
@EApplication
@EApplication public class MyApplication extends Application { }
@EActivity public class MyActivity extends Activity { @App MyApplication application; }
@EService public class MyService extends Service { }
MyService_.intent(getApplication()).start();
MyService_.intent(getApplication()).stop();
@EReceiver public class MyReceiver extends BroadcastReceiver { }
@EActivity public class MyActivity extends Activity { @Receiver(actions = "org.androidannotations.ACTION_1") protected void onAction1() { } }
@EProvider public class MyContentProvider extends ContentProvider { }
@EActivity public class MyActivity extends Activity { // Injects R.id.myEditText,變量名稱必須和布局的id名稱一致 @ViewById EditText myEditText; @ViewById(R.id.myTextView) TextView textView; }
@EActivity(R.layout.main) public class MyActivity extends Activity { @ViewById TextView myTextView; @AfterViews void updateTextWithDate() {//一定要在這裡進行view的一些設置,不要在oncreate()中設置,因為oncreate()在執行時 view還沒有注入myTextView.setText("Date: " + new Date()); }[...]
@EActivity public class MyActivity extends Activity { @StringRes(R.string.hello) String myHelloString;//不能設置成私有變量 @StringRes String hello; }
@EActivity public class MyActivity extends Activity { @ColorRes(R.color.backgroundColor) int someColor; @ColorRes int backgroundColor; }
@EActivity public class MyActivity extends Activity { @AnimationRes(R.anim.fadein) XmlResourceParser xmlResAnim; @AnimationRes Animation fadein; }
@EActivity public class MyActivity extends Activity { @DimensionRes(R.dimen.fontsize) float fontSizeDimension; @DimensionRes float fontsize; }
@EActivity public class MyActivity extends Activity { @DimensionPixelOffsetRes(R.string.fontsize) int fontSizeDimension; @DimensionPixelOffsetRes int fontsize; }
@EActivity public class MyActivity extends Activity { @DimensionPixelSizeRes(R.string.fontsize) int fontSizeDimension; @DimensionPixelSizeRes int fontsize; }
@BooleanRes
@ColorStateListRes
@DrawableRes
@IntArrayRes
@IntegerRes
@LayoutRes
@MovieRes
@TextRes
@TextArrayRes
@StringArrayRes
@EActivity public class MyActivity extends Activity { @Extra("myStringExtra") String myMessage; @Extra("myDateExtra") Date myDateExtraWithDefaultValue = new Date(); }
@EActivity public class MyActivity extends Activity { // The name of the extra will be "myMessage",名字必須一致 @Extra String myMessage; }
MyActivity_.intent().myMessage("hello").start() ;
@EActivity public class MyActivity extends Activity {// @SystemService NotificationManager notificationManager; }
@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; }
@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; }
public class MyActivity extends Activity {//等同於 Activity.onRetainNonConfigurationInstance() @NonConfigurationInstance Bitmap someBitmap; @NonConfigurationInstance @Bean MyBackgroundTask myBackgroundTask; }
@HttpsClient HttpClient httpsClient;
@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(); } }
@EFragment public 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(R.id.myButton) void myButtonWasClicked() { [...] } @Click void anotherButton() {//如果不指定則函數名和id對應 [...] } @Click void yetAnotherButton(View clickedView) { [...] }
@Click
@LongClick
@Touch
@ItemClick
@ItemLongClick
@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) { } }
@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) { } }
//等同於SeekBar.OnSeekBarChangeListener.onProgressChanged(SeekBar, int, boolean)

@EActivity @OptionsMenu({R.menu.my_menu1, R.menu.my_menu2}) public class MyActivity extends Activity { }
void myMethod() { someBackgroundWork("hello", 42); } @Background void someBackgroundWork(String aParam, long anotherParam) { [...] }
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); }
@Background(delay=2000) void doInBackgroundAfterTwoSeconds() { }
void myMethod() { doInUiThread("hello", 42); } @UiThread void doInUiThread(String aParam, long anotherParam) { [...] }
@UiThread(delay=2000) void doInUiThreadAfterTwoSeconds() { }
@UiThread(propagation = Propagation.REUSE) void runInSameThreadIfOnUiThread() { }
@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(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() { }
對於自定義view,可能是一個比較大的瓶頸期。筆者也是如此,就像毛主席說的,抓住主要矛盾,一切都不難。一些大神也聲稱過自定義view並不難。PS筆者比較實在,是真還沒到感
