前段時間在做友盟分享 要求分享指定view  並儲存 下面是我常用的幾個方法  給大家分享一下：

      1.第一個方法： 

 /**
 * 根據指定的view截圖 並儲存
 * @param v 要截圖的view
 * @return Bitmap
 */
public void getViewBitmap(View v) {
    if (null == v) {
        return;
    }
    v.setDrawingCacheEnabled(true);
    v.buildDrawingCache();
    if (Build.VERSION.SDK_INT >= 11) {
        v.measure(View.MeasureSpec.makeMeasureSpec(v.getWidth(), View.MeasureSpec.EXACTLY),
                View.MeasureSpec.makeMeasureSpec(v.getHeight(), View.MeasureSpec.EXACTLY));
        v.layout((int) v.getX(), (int) v.getY(), (int) v.getX() + v.getMeasuredWidth(), (int) v.getY() + v.getMeasuredHeight());
    } else {
        v.measure(View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED),
                View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
        v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());
    }

    Bitmap bitmap = Bitmap.createBitmap(v.getDrawingCache(), 0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());
    v.setDrawingCacheEnabled(false);
    v.destroyDrawingCache();
    //儲存到相簿
    MediaStore.Images.Media.insertImage(getContentResolver(), bitmap, "***" + System.currentTimeMillis(), "分享圖片");
    //廣播通知重新整理相簿
    sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,
            Uri.fromFile(new File("/sdcard/Boohee/image.jpg"))));
    ToastManager.toast("儲存成功");
}
 

2.第二個方法：

/**
 * 將view轉化為bitmap
 */
public static Bitmap view2Bitmap(final View view) {
    if (view == null) return null;
    Bitmap ret = Bitmap.createBitmap(view.getWidth(),
            view.getHeight(),
            Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(ret);
    Drawable bgDrawable = view.getBackground();
    if (bgDrawable != null) {
        bgDrawable.draw(canvas);
    } else {
        canvas.drawColor(Color.WHITE);
    }
    view.draw(canvas);
    return ret;
}
 

3.友盟分享方法：

/**
 * 分享圖片
 */
public static void WxBitmapShare(Context context, Bitmap bitmap, SHARE_MEDIA platform) {
    if (!WeiXinInstallUtils.isWeixinAvailable(context)) {
        ToastManager.toast("請先安裝微信");
        return;
    }
    UMImage image = new UMImage(context, bitmap);
    new ShareAction((Activity) context)
            .withText("哈哈")
            .setPlatform(platform)
            .withMedia(image)
            .setCallback(new UMShareListener() {
                @Override
                public void onStart(SHARE_MEDIA share_media) {

                }

                @Override
                public void onResult(SHARE_MEDIA share_media) {
                    ToastManager.toast("分享成功");
                }

                @Override
                public void onError(SHARE_MEDIA share_media, Throwable throwable) {
                    if (throwable != null) {
                        Log.d("throw", "throw:" + throwable.getMessage());
                    }
                    ToastManager.toast("分享失敗");
                }

                @Override
                public void onCancel(SHARE_MEDIA share_media) {
                    ToastManager.toast("分享取消");
                }
            }).share();
}
 

下面是具體使用：

Bitmap mWXShareBitmap = view2Bitmap(iv_bg);
ShareUtils.WxBitmapShare(context, mWXShareBitmap, 分享平臺);
