Android - 常见问题XML android:adjustViewBounds 让ImageView根据图片的实际

XML

<androidx.appcompat.widget.AppCompatImageView
    android:id="@+id/iv_title_vip"
    android:layout_marginStart="12dp"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    android:scaleType="fitStart"
    android:adjustViewBounds="true"
    android:layout_width="wrap_content"
    android:layout_height="20dp"/>

android:adjustViewBounds 让ImageView根据图片的实际宽高比自动调整边界

方法block回调，参数透传

fun checkShowEmoteGuide(callback: (() -> Unit)?= null) {

  callback?.invoke()
  
}

fun videoFeedConfig(val scene: String?, val canSlide: Boolean? = false) {

}

接收 new

emoteView.checkShowEmoteGuide(new Function0<Unit>() {
    @Override
    public Unit invoke() {
        isShowEmote = true;
        return null;
    }
});

本地存储

getUserSp 用户纬度

UserHelper.getGlobleSp 设备纬度

UserHelper.getGlobleSp().putBoolean(PreferencesConst.POST_INFO_COMMENT_GUIDE, true);

boolean isShowComment = UserHelper.getGlobleSp().getBoolean(PreferencesConst.POST_INFO_COMMENT_GUIDE, false);

动画

java

contentView.animate()
        .alpha(0f)
        .setDuration(300)
        .withEndAction(new Runnable() {
            @Override
            public void run() {
                if (guidePopupWindow != null) {
                    guidePopupWindow.safeDismiss();
                    guidePopupWindow = null;
                }
            }
        })
        .start();

contentView.alpha = 0f
contentView.animate()
    .alpha(1f)
    .setDuration(300)
    .start()

runnable 任务

private Runnable showGuidePopupRunnable() {
    return new Runnable() {
        @Override
        public void run() {
            mBottomView.removeCallbacks(null);
            if (isShowEmote == false && guidePopupWindow != null && commentContentOnTheScreen(1)) {
                guidePopupWindow.showAsDropDown(mBottomView, DpAndPxUtils.dip2px(-16), DpAndPxUtils.dip2px(-100));
                isShowComment = true;
                UserHelper.getGlobleSp().putBoolean(PreferencesConst.POST_INFO_COMMENT_GUIDE, true);
                contentView.setAlpha(0f);
                contentView.animate()
                        .alpha(1f)
                        .setDuration(300)
                        .start();

                mBottomView.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        dismissGuidePopup();
                    }
                }, 3000);
            }
        }
    };
}

延迟展示

mBottomView.postDelayed(showGuidePopupRunnable(), 3000);

操作取消

mBottomView.removeCallbacks(null);

弱引用

// 改用静态内部类 + 弱引用解决
private static class SafeRunnable implements Runnable {
    private final WeakReference<Activity> activityRef;
    private final WeakReference<View> anchorViewRef;
    private final OnShowGuideTipListener listener;

    SafeRunnable(Activity activity, View view, OnShowGuideTipListener l) {
        this.activityRef = new WeakReference<>(activity);
        this.anchorViewRef = new WeakReference<>(view);
        this.listener = l;
    }

    @Override
    public void run() {
        Activity activity = activityRef.get();
        View view = anchorViewRef.get();
        if (activity == null || view == null) return;
        
        dismissGuideTipBox();
        if (listener != null) {
            listener.showGuideTip();
        }
    }
}

imageloader 图片加载

private void loadImg(String imgUrl, ImageView imageView, boolean autoSize, int width, int height) {
    if (!TextUtils.isEmpty(imgUrl)) {
        IImageLoader imageLoader = ImageLoader.get(context).load(imgUrl)
                .autoSize(autoSize);
        if (width > 0) {
           imageLoader = imageLoader.urlWidth(width);
        }
        if (height > 0) {
            imageLoader = imageLoader.urlHeight(height);
        }
        if (width > 0 && height > 0 && !autoSize) {
            imageLoader = imageLoader.size(width, height);
        }
        imageLoader.target(new LoadCompleteCallback<Bitmap>() {
                    @Override
                    public void onLoadComplete(Bitmap resource) {
                        if (resource != null) {
                            imageView.setImageBitmap(resource);
                        }
                    }

                    @Override
                    public void onLoadFailed(Exception info) {

                    }
                }).request();
    }
}

IDE报错

Couldn't resolve the package 'shimmer' in 'package:shimmer/shimmer.dart'.

local.properties

本地 #application.debug.flutterAAR=false

ndk {
    abiFilters "armeabi-v7a"
    packagingOptions {
        doNotStrip "*/armeabi-v7a/*.so"
    }
}

安卓硬改32位系统在64位上运行

跳转到flutter页面

HashMap<String, Object> maps = new HashMap<>();

maps.put("blogId", blogId);

maps.put("otherBlogId", otherBlogId);

maps.put("otherBlogName", otherBlogName);

maps.put("dnd", dndInt);

maps.put("menuShowStatus", isMenuStyleInt);

FlutterNativeManager.route(((Activity) mcontext), RouteConfig.SingleChatDetailPage, maps);
