OpenCV : build with Glade on Android Studio

codejie — Tue, 14 Apr 2015 15:54:00 GMT

FROM : http://stackoverflow.com/questions/17767557/how-to-use-opencv-in-android-studio-using-gradle-build-tool

Android Studio 0.8.2+ and above, could easily import modules. Thanks to TGMCains answer, is simplified, by using Android Studio itself to import OpenCV as a module.

Download latest OpenCV sdk for Android from OpenCV.org and decompress the zip file.
Import OpenCV to Android Studio, From File -> Import Module, choose sdk/java folder in the unzipped opencv archive.
Update build.gradle under imported OpenCV module to update 4 fields to match your project build.gradle a) compileSdkVersion b) buildToolsVersion c) minSdkVersion and 4) targetSdkVersion.
Add module dependency by Application -> Module Settings, and select the Dependenciestab. Click + icon at bottom, choose Module Dependency and select the imported OpenCV module.
Copy libs folder under sdk/native to Android Studio under app/src/main.
In Android Studio, rename the copied libs directory to jniLibs and we are done.

Step (6) is since Android studio expects native libs in app/src/main/jniLibs instead of older libs folder. For those new to Android OpenCV, don't miss below steps

include static{ System.loadLibrary("opencv_java"); }
For step(5), if you ignore any platform libs like x86, make sure your device/emulator is not on that platform.

OpenCV written is in C/C++. Java wrappers are

Android OpenCV SDK - OpenCV.org maintained Android Java wrapper. I suggest this one.
OpenCV Java - OpenCV.org maintained auto generated desktop Java wrapper.
JavaCV - Popular Java wrapper maintained by independent developer(s). Not Android specific. This library might get out of sync with OpenCV newer versions.

Android DEV : Show a window on Baidu Map

codejie — Wed, 18 Jun 2014 12:22:00 GMT

周末同学说想弄个��Z��Baidu地图的应�? 于是��开始研�I�这个SDK�? 其中应用有个需�? 需要点��d��图上的标记时, 昄��一�l�按�? 于是按照常规的作法失业了(ji��n)InfoWindow, 如下.

    //panel is a view, some buttons in it.
    final InfoWindow iw = new InfoWindow(panel, marker.getPosition(), null);
    //getMap() return BaiduMap
    activity.getMap().showInfoWindow(iw);

倒是不难, 但处理点��M��件时发现有问题了(ji��n). �Ҏ(gu��)��文��, 此时昄��出来的InfoWindow实际是View的Bitmap囄��, 也就意味着�Ҏ(gu��)��没法区分View上的Buttons�? 更别说能处理Button的点��M��件了(ji��n). 怪不�? 文��中对于整个InfoWindow只有一个ClickListener, �q�不含有View信息.

�q�样只能"曲线救国"�? InfoWindow不能�? 那就直接在MapView中弹��Z��PopupWindow�? (��手敲打��试代码, ��p��录用)

    final View panel = UserPanel.make(activity);
    Point p = activity.getMap().getProjection().toScreenLocation(marker.getPosition());

    final PopupWindow pw = new PopupWindow(panel);
    pw.setWidth(ViewGroup.LayoutParams.WRAP_CONTENT);
    pw.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);
    pw.setFocusable(true);
    pw.setOutsideTouchable(true);
    //getMapView() return MapView, not BaiduMap any more
    pw.showAtLocation(activity.getMapView(), Gravity.LEFT | Gravity.BOTTOM,p.x, p.y );

    final Button btn = (Button) panel.findViewById(R.id.button2);
    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            pw.dismiss();
        }
    });

搞定,人长个脑袋��L��有用�?..

��试中发��C��问题, 如果地图发生攄��, Window弹出的位�|�会(x��)不准��? 很是奇�? 按理MapView发生变化�? 其Projection应该能够实时跟随变化�? �q�个问题回头需要再看看.

<---- 回过头的分割�U?---->
位置不准��的问题是由于View和Screen坐标�p�M��? 以及(qi��ng)MapView自��nsize共同影响�? 错怪了(ji��n)Projection�?.

Android DEV : setOnClickListener() vs. android:onClick

codejie — Fri, 06 Jun 2014 13:40:00 GMT

晚上查看一�D�资源xml文�g�? 发现View竟然有个'android:onClick'属�?..�q�太'震惊'�?..

刚开始敲Android�? ��想�q�这个问�?-- android把资源文件用的如此灵�z? 为啥View控�g不能在资源文件中直接定义各类事�g回调函数�? 后来敲多�? 发现如果直接在资源文件中定义事�g处理属�? �q�会(x��)限制资源文�g的��? 像是同一份资源文件如果被两个不同的Activity使用, 那就必须各自写一个事件回调处理函�? 如果没有, 一旦事件被触发, 那就是异常啊; 另外, 如果资源文�g被一个Fragment使用, 且在Fragment实现�?ji��n)事件处理函�? 那当Fragment加入到Activity�? 怕系�l�就找不到这个函��C��(ji��n). 因此, 觉得没有'android:onClick'�q�样的属性该是正常的, 后面也就没再惌��q�个�? 每次都很老实的��用View.setOnClickListener()�?..

�? 现在�q�个属性竟然真是存�? 而且一直都�? �q�太让我'崩溃'�?..那感觉就像走在大街上, �H�然看到有�h在遛 --- 恐龙一�?..

于是, 赶紧写了(ji��n)代码��试�?ji��n)下~

	public void onButtonClick(View view) {
		Log.d(Tag, "onButtonClick()");		
	}

果然好用...但突然想�? 如果�q�个跟View.setOnClickListener()共存�? 调用�q�程该是如何�?

		Button btn = (Button) this.findViewById(R.id.button1);
		btn.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				Log.d(Tag, "onClickListener - onClick()");
			}
			
		});

��试�l�果�?OnClilckListener()中的onClick()�?x��)被调�? 而android:onClick定义的onButtonClick()完全被忽略了(ji��n).

��如前面提到�? �q�种属性设�|�的方式有些�~�陷, �q�是使用setOnClickListener()比较可控靠谱, 当然如果在布局文�g使用比较固定的情况下, �q�种属性定义方式确实可以少敲很多代�?

��Z��试�l�果, �H�然'抖机�?地想��C��D�代码来 -- 如果在onButtonClick()中调用setOnClickListener()�?x��)怎样�?

	public void onButtonClick(View view) {
		Log.d(Tag, "onButtonClick()");
		
		Button btn = (Button) this.findViewById(R.id.button1);
		btn.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				Log.d(Tag, "onClickListener - onClick()");
			}
			
		});		
	}

�q�样�W�一�ơ点�?y��n)L��, 执行onButtonCllick(), �q�将View的点��M��件处理通过setOnClickListener()传到OnClickListener()�? 当再�ơ被点击�? ��׃��(x��)执行onClick()�? �q�就可以实现一�U�需�?-- 点一�ơ没�? 再点��崩�?..�Ҏ(gu��)��不用加什么判断变量和语句�? 嘿嘿, �?机智'�?..

SnakeGo : Scaling Screen on Stage II

codejie — Wed, 21 May 2014 15:59:00 GMT

昨晚把BaseScreen��敲好了(ji��n), 也找��C��(ji��n)屏幕攄��的最优和最��方式. 不多�? 看代�?

	public BaseScreen(final SnakeGo game) {
		super(new ScalingViewport(Scaling.fit, CommonConsts.Screen.WIDTH, CommonConsts.Screen.HEIGHT, new OrthographicCamera()), new SpriteBatch());		

		this.game = game;
		
		Gdx.input.setInputProcessor(this);
	}

BaseScreen直接�l�承与Stage是个好方�? 很方便��用Stage所提供的各�U�渲�?输入相关的函�? 但这样如果考虑MVC风格的话, M和C��g��׃��该在Screen存在, 但却又没地方攄��...当然�q�样可能有些死脑�{�了(ji��n). (我在Snake对象中分��M��(ji��n)M和C).

在构造函��C��, 使用Scaling的fit方式来初始Stage, 可以保证屏幕'居中攄��', �q�在resize()�? 更新��寸卛_��.

	@Override
	public void resize(int width, int height) {
		this.getViewport().update(width, height, true);
	}

�q�方法有些简单的让�h不敢�怿�...

<---- LIBGDX��众的分割线 ---->

�q�两天留意些Game相关的招聘信�? 发现Libgdx真是��众�? 一个都没有, ��N��真的像朋友说�?-- "也就你自��q��玩吧...". LIBGDX相对比较'�?, 用�v来虽说有�?复杂', 但对于研�I�个'架构'什么的, 真的很不错的....�? ��N��我也转向cocos2d-x�?

SnakeGo : Scaling Screen on Stage

codejie — Mon, 19 May 2014 15:11:00 GMT

刚才使用LIBGDX的Stage�? 发现1.0.1�?.99的一个变�?-- Stage内置Camera和Viewport(好用的ScalingViewport�c?. 如此�q�样, 那放�~�屏�q�更方便�?..

	@Override
	public void resize(int width, int height) {
		
		Vector2 size = Scaling.fit.apply(CommonConsts.Screen.WIDTH, CommonConsts.Screen.HEIGHT, width, height);	
		this.getViewport().update((int)size.x, (int)size.y, true);

//		Vector2 screenScaling = new Vector2((size.x / CommonConsts.Screen.WIDTH), (size.y / CommonConsts.Screen.HEIGHT));
//		this.getRoot().setScale(screenScaling.x, screenScaling.y);
	}

Stage内置的Camera和Viewport�?原点'攑֜�左下�? 而不是常使用�?居中', 另外�q�个�q�有个问�? 当屏�q�羃放时, Viewport也不是一般习(f��n)�?居中'昄��, 也是是靠左下. 我简单查看了(ji��n)下相应的Viewport�c? 没有发现如何讄��q�个偏移�? 只是SnakeGo'竖屏'模式在N4上正�?铺满', �q�个问题再说�? 如果需�? 能预估最�ȝ��(ch��)的就是重载ScalingViewport�c�M��(ji��n).

代码�? 后面注释掉的两句是用于等比例攄��囑�Ş�? �q�没认真��过, ��g��不需要也可以�? 需要再看看Viewport�c?.

SnakeGo : Scaling Screen and Moving Camera

codejie — Sun, 18 May 2014 11:24:00 GMT

敲了(ji��n)几晚SnakeGo, 原型出来�? 大家来看看不...

不错, �q�货��是---贪吃�?..哈哈...别�? �q�还是原�? 好玩的在后面�?..(以我敲字速度, 大约再等不到六个月应该可以完成了(ji��n)...)

今天�q�里记录下��用LIBGDX�q�程中碰到的两个问题:

1. 调整屏幕比例;

2. �U�d��观察镜头;

一, 调整屏幕比例

LIBGDX是跨�q�_��? 一大好处就是直接在PC上测�? 那是非常的方�? 但这有两个问题需要考虑, 一, 手机�?280x768, 但我PC只有1280x1024�? 而且真要开个跟手机一样大��的一样大��的屏幕, 那还怎么看log输出�? 二就是不同的手机有着不同的分辨率, 长宽比也不一�? 那怎么保证囑�Ş不变形呢?

�q�个问题不难解决, 只需要在屏幕��寸发生变化�? 即resize()(�W�一�ơ启动也�?x��)调用此函�?�? 重新调整镜头(Camera)的参数即�? 如下代码:

	@Override
	public void resize(int width, int height) {
		Vector2 size = Scaling.fit.apply(WIDTH, HEIGHT, width, height);
		
		camera = new OrthographicCamera(size.x, size.y);
		camera.update();

		batch.setProjectionMatrix(camera.combined);
	    
              int viewportX = (int)(width - size.x) / 2;
	       int viewportY = (int)(height - size.y) / 2;
	       int viewportWidth = (int)size.x;
	       int viewportHeight = (int)size.y;
	    
		Gdx.gl.glViewport(viewportX, viewportY, viewportWidth, viewportHeight);

		super.resize(width, height);
	}

�q�里采用的是重新创徏camera实例的方�? 另外用改变已有camera实例的参数方式也是一��L(f��ng)��. 很简�? 而且�q�样一�ơ就解决�?ji��n)上面两个问�?-- PC��Z��使用��M��寸的窗�? 都可以获得跟讄��{�比例的�H�口, 手机上亦是如�? �?a href="http://www.shnenglu.com/codejie/category/20828.html">I;P��是采用的这�U�方式来保持其在��L��手机上都�?280:768的比�?

�q�种�Ҏ(gu��)��只是改变�?视图'的大��? 但�ƈ不会(x��)改变其中的图形的大小, �q�样��Z��(ji��n)保持囑�Ş昄��比例, 需要在输出囑�Ş时做相应的比例放�~? 可以在resize()获得�q�个比例, 染在囑�Ş输出时��用这个比�?

              screenScaling = new Vector2((size.x / WIDTH), (size.y / HEIGHT));

              ...
              ...
              batch.draw(img, (- WIDTH / 2) * screenScaling.x, (- HEIGHT / 2) * screenScaling.y, WIDTH * screenScaling.x, HEIGHT * screenScaling.y);

�? �U�d��观察镜头

在SnakeGo�? ��Z��(ji��n)不让Snake'跑出'屏幕, 需要镜头camera跟Snake本��n保持'同步'�U�d��, �q�样看�v来Snake保持在屏�q�的中间, 但其它Object是移动的. �Ҏ(gu��)��'相对�q�行'原理, 使整个看��h��像是Snake在Object中穿�? 所�? �U�d��camaera是必��ȝ��, 代码也简�? 如下:

              ...
		final OrthographicCamera camera = game.getCamera();
		camera.translate(0.0f, 32.0f, 0.0f);
		camera.update();
		game.getSpriteBatch().setProjectionMatrix(camera.combined);
              ...
