Question

我有一个应用程序，我试图从链接中检索图像，我通过谷歌集成。但是，每当我尝试将图片放入位图时，它总会给我一个错误。代码和错误如下：

代码：

if (google_user_gallery_pic.isEmpty() == true)
{
    if (google_user_pic.isEmpty() == false)
    {
        onPost = null;
        onPost2 = null;
        onPost = getBitmapFromURL(google_user_pic);
        onPost2 = onPost2.createScaledBitmap(onPost, 100, 100, false);
    }

    else
    {
        onPost = null;
        onPost2 = null;
        onPost = BitmapFactory.decodeFile(google_user_gallery_pic);
        if (onPost == null)
        {
            onPost2 = BitmapFactory.decodeResource(getResources(), R.drawable.the_smallperson);
        }

        else
        {
            onPost2 = onPost2.createScaledBitmap(onPost, 100, 100, false);
        }
    }
}

else
{
    onPost = null;
    onPost2 = null;
    onPost = BitmapFactory.decodeFile(google_user_gallery_pic);
    if (onPost == null)
    {
        onPost2 = BitmapFactory.decodeResource(getResources(), R.drawable.the_smallperson);
        //onPost2 = onPost2.createScaledBitmap(onPost, 100, 100, false);
    }

    else
    {
        onPost2 = onPost2.createScaledBitmap(onPost, 100, 100, false);
    }
}

错误：

E/BitmapFactory: Unable to decode stream: java.io.FileNotFoundException: https:/lh3.googleusercontent.com/-HW5Tk9h1V2I/AAAAAAAAAAI/AAAAAAAADA8/7UbMeHbyFLM/photo.jpg: open failed: ENOENT (No such file or directory)

尝试将if和else条件反转为以下内容：

if (google_user_gallery_pic.isEmpty() == false)
{
    if (google_user_pic.isEmpty() == false)
    {
        onPost = null;
        onPost2 = null;
        onPost = getBitmapFromURL(google_user_pic);
        onPost2 = onPost2.createScaledBitmap(onPost, 100, 100, false);
    }

    else
    {
        onPost = null;
        onPost2 = null;
        onPost = BitmapFactory.decodeFile(google_user_gallery_pic);
        if (onPost == null)
        {
            onPost2 = BitmapFactory.decodeResource(getResources(), R.drawable.the_smallperson);
        }

        else
        {
            onPost2 = onPost2.createScaledBitmap(onPost, 100, 100, false);
        }
    }
}

else
{
    onPost = null;
    onPost2 = null;
    onPost = BitmapFactory.decodeFile(google_user_gallery_pic);
    if (onPost == null)
    {
        onPost2 = BitmapFactory.decodeResource(getResources(), R.drawable.the_smallperson);
        //onPost2 = onPost2.createScaledBitmap(onPost, 100, 100, false);
    }

    else
    {
        onPost2 = onPost2.createScaledBitmap(onPost, 100, 100, false);
    }
}

因为给定了权限和其他任何内容而不是此代码段，除此之外没有任何其他错误

尝试使用picasso从URL加载图像位图。

 private Target mTarget;   //declare variable

void loadImage(Context context, String url) {

    final ImageView imageView = (ImageView) findViewById(R.id.image);

    mTarget = new Target() {
        @Override
        public void onBitmapLoaded (final Bitmap bitmap, Picasso.LoadedFrom from){
            //Do something on the bitmap
            imageView.setImageBitmap(bitmap); //set the bitmap
        }

        @Override
        public void onBitmapFailed(Drawable errorDrawable) {

        }

        @Override
        public void onPrepareLoad(Drawable placeHolderDrawable) {

        }
    };

    Picasso.with(context)
            .load(url)
            .into(mTarget);
            ..error(R.drawable.the_smallperson) // will be displayed if the image cannot be loaded
}

在gradle中添加：

compile 'com.squareup.picasso:picasso:2.5.2'
