如何将位图转换为 Uri? [英] How can I transform a Bitmap into a Uri?

问题描述

我正在尝试使用 Android 中的 SHARE INTENT 与 Facebook、Twitter 等分享图片.

I'm trying to share images with Facebook, twitter, etc using SHARE INTENT from Android.

我找到了将图像发送到共享意图的代码，但此代码需要位图的 URI:fullSizeImageUri

I found code to send a image to the share intent, but this code needs the URI of the bitmap: fullSizeImageUri

这是完整的代码:

private void startShareMediaActivity(Bitmap image) {
    boolean isVideo=false;
    String mimeType="bmp";
    Uri fullSizeImageUri=null;
    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_SEND);
    intent.setType(mimeType);
    intent.putExtra(Intent.EXTRA_STREAM, fullSizeImageUri);
    try {
        startActivity(Intent.createChooser(intent, (isVideo ? "video" : "image")));
    } catch (android.content.ActivityNotFoundException ex) { }
}
