一,继承SimpleViewManager<View> 实现如下方法,自定义方法@ReactProp(name=”。。。。“)如下所示
** * 图片加载控件 * Created by ybj on 2016/2/24. */ public class ReactImageManager extends SimpleViewManager<ReactImageView> { public static final String REACT_CLASS = "RCTTBImage"; @Override public String getName() { return REACT_CLASS; } @Override protected ReactImageView createViewInstance(ThemedReactContext reactContext) { // ReactImageView imageView= new ReactImageView(reactContext); ReactImageView imageView = new ReactImageView(reactContext,Fresco.newDraweeControllerBuilder(),null); imageView.setScaleType(ImageView.ScaleType.FIT_XY); return imageView; } /* @ReactProp(name = PROP_TEST_ID) @Override public void setTestId(ImageView view,int testId) { super.setTestId(view,testId); } */ //图片url设置 @ReactProp(name = "urlPath") public void setUrlPath(ReactImageView view,@Nullable String url) { Log.d("TAG_YBJ","setUrl" + url); if (url.toLowerCase().endsWith(".gif")) { /* DraweeController controller = Fresco.newDraweeControllerBuilder().setUri(url) .setAutoPlayAnimations(true).build(); this.setController(controller);*/ } else { /*this.setImageURI(Uri.parse(url));*/ } view.setSource(url); // Image13lLoader.getInstance().loadImage(url,view); } //边角度数设置 @ReactProp(name = "borderRadius",defaultFloat = 0f) public void setBorderRadius(ReactImageView view,float borderRadius) { view.setBorderRadius(borderRadius); } //缩放类型 @ReactProp(name = ViewProps.RESIZE_MODE) public void setResizeMode(ReactImageView view,@Nullable String resizeMode) { view.setScaleType(ImageResizeMode.toScaleType(resizeMode)); } }
二,实现 ReactPackage
/** * 图片加载 需要加载图片需要注册this * Created by ybj on 2016/2/24. */ public class ReactImagePackage implements ReactPackage { @Override public List<NativeModule> createNativeModules(ReactApplicationContext reactContext) { return Collections.emptyList(); } @Override public List<Class<? extends JavaScriptModule>> createJSModules() { return Collections.emptyList(); } @Override public List<ViewManager> createViewManagers(ReactApplicationContext reactContext) { return Arrays.<ViewManager>asList( new ReactImageManager()); } }三,添加package.setApplication(((Activity) mContext).getApplication()) .setJSBundleFile(bundleFile) // .setJSMainModuleName("test") .setNativeModuleCallExceptionHandler(new NativeModuleCallExceptionHandler() { @Override public void handleException(Exception e) { } }) /* .setBundleAssetName("webviewindex.bundle") .setJSMainModuleName("webviewindex")*/ .addPackage(new TBRnPackage()) .addPackage(new ReactImagePackage()) .setUseDeveloperSupport(false) .setInitialLifecycleState(LifecycleState.RESUMED) .build(); mReactRootView.startReactApplication(mReactInstanceManager,"BZMHomeOperationActivity",null); myreact.addView(mReactRootView);
