Android实现截屏和截长图功能的各种方法

微信好友或者朋友圈的分享，可以是普通的截图分享，也可以是截取长图的分享，甚至还会有需求让你拼上生成的二维码和logo图片，下面我们直接来看看这些方法的使用：

先说一下拼接三张不同的图片后有黑色背景的解决方案(在下面的6拼接合成图片的方法里加上就可以了)：

//设置画布背景色为白色，即自定义控件显示的背景色为白色：
        canvas.drawRGB(255,255,255);

1.普通的截屏方法

/**
     * 截屏
     *
     * @param activity
     * @return
     */
    public static Bitmap activityShot(Activity activity) {
       /*获取windows中最顶层的view*/
        View view = activity.getWindow().getDecorView();
        //允许当前窗口保存缓存信息
        view.setDrawingCacheEnabled(true);
        view.buildDrawingCache();
        //获取状态栏高度
        Rect rect = new Rect();
        view.getWindowVisibleDisplayFrame(rect);
        int statusBarHeight = rect.top;
        WindowManager windowManager = activity.getWindowManager();
        //获取屏幕宽和高
        DisplayMetrics outMetrics = new DisplayMetrics();
        windowManager.getDefaultDisplay().getMetrics(outMetrics);
        int width = outMetrics.widthPixels;
        int height = outMetrics.heightPixels;
        //去掉状态栏
        Bitmap bitmap = Bitmap.createBitmap(view.getDrawingCache(), 0, statusBarHeight, width, height - statusBarHeight);
        //销毁缓存信息
        view.destroyDrawingCache();
        view.setDrawingCacheEnabled(false);
        return bitmap;
    }

2.截取scrollView的屏幕方法

/**
     * 截取scrollview的屏幕
     * @param scrollView
     * @return
     */
    public static Bitmap getBitmapByView(ScrollView scrollView) {
        int h = 0;
        Bitmap bitmap = null;
        // 获取listView实际高度
        for (int i = 0; i < scrollView.getChildCount(); i++) {
            h += scrollView.getChildAt(i).getHeight();
            scrollView.getChildAt(i).setBackgroundResource(R.drawable.white_drawable);
        }

        // 创建对应大小的bitmap
        bitmap = Bitmap.createBitmap(scrollView.getWidth(), h,
                Bitmap.Config.ARGB_8888);
        final Canvas canvas = new Canvas(bitmap);
        scrollView.draw(canvas);
        // 测试输出
        FileOutputStream out = null;
        try {
            out = new FileOutputStream("/sdcard/screen_test.png");
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
        try {
            if (null != out) {
                bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
                out.flush();
                out.close();
            }
        } catch (IOException e) {
            // TODO: handle exception
        }
        return bitmap;
    }

3.截取ListvListView的屏幕方法

/**
     *  截图listview
     * **/
    public static Bitmap getbBitmap(ListView listView) {
        int h = 0;
        Bitmap bitmap = null;
        // 获取listView实际高度
        for (int i = 0; i < listView.getChildCount(); i++) {
            h += listView.getChildAt(i).getHeight();
        }

        // 创建对应大小的bitmap
        bitmap = Bitmap.createBitmap(listView.getWidth(), h,
                Bitmap.Config.ARGB_8888);
        final Canvas canvas = new Canvas(bitmap);
        listView.draw(canvas);
        // 测试输出
        FileOutputStream out = null;
        try {
            out = new FileOutputStream("/sdcard/screen_test.png");
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
        try {
            if (null != out) {
                bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
                out.flush();
                out.close();
            }
        } catch (IOException e) {
            // TODO: handle exception
        }
        return bitmap;
    }

4.截取线性布局或相对布局屏幕的方法

/**
     * 截取RelativeLayout
     **/
    public static Bitmap getRelativeLayoutBitmap(RelativeLayout relativeLayout) {
        int h = 0;
        Bitmap bitmap;
        for (int i = 0; i < relativeLayout.getChildCount(); i++) {
            h += relativeLayout.getChildAt(i).getHeight();
        }
        // 创建对应大小的bitmap
        bitmap = Bitmap.createBitmap(relativeLayout.getWidth(), h,
                Bitmap.Config.ARGB_8888);
        final Canvas canvas = new Canvas(bitmap);
        relativeLayout.draw(canvas);
        return bitmap;
    }
    /**
     * 截取LinearLayout
     **/
    public static Bitmap getLinearLayoutBitmap(LinearLayout linearLayout) {
        int h = 0;
        Bitmap bitmap;
        for (int i = 0; i < linearLayout.getChildCount(); i++) {
            h += linearLayout.getChildAt(i).getHeight();
        }
        // 创建对应大小的bitmap
        bitmap = Bitmap.createBitmap(linearLayout.getWidth(), h,
                Bitmap.Config.ARGB_8888);
        final Canvas canvas = new Canvas(bitmap);
        linearLayout.draw(canvas);
        return bitmap;
    }

5.截取除了导航栏之外的整个屏幕

/**
     * 截取除了导航栏之外的整个屏幕
     */
    public static Bitmap screenShotWholeScreen(Activity activity) {
        View dView = activity.getWindow().getDecorView();
        dView.setDrawingCacheEnabled(true);
        dView.buildDrawingCache();
        Bitmap bitmap = Bitmap.createBitmap(dView.getDrawingCache());
        return bitmap;
    }

6.拼接合成图片的方法

 //合成三张图片
    private static Bitmap mergeBitmap(Bitmap firstBitmap, Bitmap secondBitmap, Bitmap threeBitmap) {
        Bitmap bitmap = Bitmap.createBitmap(firstBitmap.getWidth(), firstBitmap.getHeight() + secondBitmap.getHeight() + threeBitmap.getHeight(), firstBitmap.getConfig());
        Canvas canvas = new Canvas(bitmap);
        canvas.drawBitmap(firstBitmap, new Matrix(), null);
        canvas.drawBitmap(secondBitmap, 0, firstBitmap.getHeight(), null);
        canvas.drawBitmap(threeBitmap, secondBitmap.getWidth(), firstBitmap.getHeight(), null);
        return bitmap;
    }
    //合成两张图片
    public static Bitmap mergeBitmap(Bitmap firstBitmap, Bitmap secondBitmap) {
        Bitmap bitmap = Bitmap.createBitmap(firstBitmap.getWidth(), firstBitmap.getHeight(),firstBitmap.getConfig());
        Canvas canvas = new Canvas(bitmap);
        canvas.drawBitmap(firstBitmap, new Matrix(), null);
        canvas.drawBitmap(secondBitmap, 0, 0, null);
        return bitmap;
    }

7.具体的调用和拼接合成图片：

     Bitmap bitmap = StringUtil.activityShot(JCZQTDetailActivity.this);
                Bitmap bitmap = StringUtil.getBitmapByView(scrollView_jc_type);//截取长图
//                Bitmap bitmap = StringUtil.getRelativeLayoutBitmap(rl_jc_all);
//                Bitmap bitmap1 = StringUtil.screenShotWholeScreen(JCZQTDetailActivity.this);
//                Bitmap bitmap2 = ShareUtil.mergeBitmap(bitmap, bitmap1);ShareUtil.weiChatPic(Constants.wx_api, 7, MakeReceiptDetailsActivity.this, bitmap2);

8.微信分享图片方法和链接生成二维码图片方法：

    public static void weiChatPic(IWXAPI api, int flag, Context context, Bitmap bitmap) {
        if (api.isWXAppInstalled()) {//判断微信是否安装
            //Bitmap mWXShareBitmap = BitmapFactory.decodeResource(context.getResources(), R.drawable.logo_icon);//将截屏得到的bitmap赋值
            GlobalLog.e("sgf", "-------GlobalEntity.USER.getUrl()-------" + GlobalConfig.getURL(context));
            if ("".equals(GlobalConfig.getURL(context)) || "null".equals(GlobalConfig.getURL(context))) {
                Intent intent = new Intent(context, LoginActivity.class);
                context.startActivity(intent);
                return;
            }
            loadRQInfo(GlobalConfig.getURL(context));
            Bitmap b = BitmapFactory.decodeResource(context.getResources(), R.drawable.sharewinlogo);
            GlobalLog.e("sgf", "-------bitmap-------" + bitmap);
            GlobalLog.e("sgf", "-------bitmaps-------" + bitmaps);
            GlobalLog.e("sgf", "-------b-------" + b);
            Bitmap bitmap1 = mergeBitmap(bitmap, bitmaps, b);

            WXImageObject imgObject = new WXImageObject(bitmap1);
            //imgObject.imagePath
            WXMediaMessage mediaMessage = new WXMediaMessage();
            mediaMessage.mediaObject = imgObject;

            //设置缩略图
            Bitmap thumbBmp = Bitmap.createScaledBitmap(bitmap1, bitmap1.getWidth() / 10, bitmap1.getHeight() / 10, true);
            mediaMessage.thumbData = bmpToByteArray(thumbBmp, true);
            SendMessageToWX.Req req = new SendMessageToWX.Req();
            req.transaction = buildTransaction("img");//分享类型是图片
            req.message = mediaMessage;
            //表示发送给朋友圈  WXSceneTimeline  表示发送给朋友  WXSceneSession
            req.scene = flag == 7 ? SendMessageToWX.Req.WXSceneSession : SendMessageToWX.Req.WXSceneTimeline;
            api.sendReq(req);
            GlobalLog.e("sgf", "-------end-------");

        } else {
            Toast.makeText(context, "您没有安装微信客户端", Toast.LENGTH_SHORT).show();
        }

 /**
     * 生成万二维码
     *
     * @param soldUrl
     */
    private static void loadRQInfo(String soldUrl) {
        //回收bitmaps
        if (null != bitmaps && !bitmaps.isRecycled()) {
            bitmaps.recycle();
            bitmaps = null;
        }
        try {
            bitmaps = StringUtil.makeQRImage(soldUrl, 480, 350);
        } catch (WriterException e) {
            e.printStackTrace();
        }
    }
