Question

我在我的应用程序中使用了ScrollView。它包含一个LinearLayout作为子项，其他一些视图喜欢 TextViews，Buttons等...作为子视图。现在我想将scrollview的内容发布为FaceBook wall上的图像。我找不到合适的帖子。

   **My question is how to post ScrollView/Layout content on facebook wall?...**

先谢谢

Answer 1

使用此功能将您的视图转换为位图图像

public Bitmap getBitmapFromView(View view) {
    Bitmap returnedBitmap = Bitmap.createBitmap(480, 640,Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(returnedBitmap);
    Drawable bgDrawable =view.getBackground();
    if (bgDrawable!=null) 
        bgDrawable.draw(canvas);
    else 
        canvas.drawColor(Color.WHITE);
    view.draw(canvas);
    return returnedBitmap;
}

然后在Facebook墙上发布位图图像

希望能帮到你..

我将上面的代码更改为

public Bitmap getBitmapFromView(View view) {

    Bitmap returnedBitmap = Bitmap.createBitmap(view.getMeasuredWidth(),
                  view.getMeasuredHeight() , Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(returnedBitmap);
    Drawable bgDrawable = view.getBackground();
    if (bgDrawable != null)
        bgDrawable.draw(canvas);
    else
        canvas.drawColor(Color.WHITE);
    view.draw(canvas);
            return returnedBitmap;
}

它工作正常，并获得所有内容的位图。
