Question

我想获取imageview realPath并编写textview。我可以在库中获取RealPath，但不能在相机中获取

这是我的代码

此代码采用库管理路径

private void takeLibrary(int sdk, String uriPath,String realPath){

    this.txtSDK.setText("Build.VERSION.SDK_INT: "+sdk);
    this.txtUriPath.setText("URI Path: "+uriPath);
    this.txtRealPath.setText(realPath);

    Uri uriFromPath = Uri.fromFile(new File(realPath));


    Bitmap bitmap = null;
    try {
        bitmap = BitmapFactory.decodeStream(getContentResolver().openInputStream(uriFromPath));

    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
    imageView.setImageBitmap(bitmap);

}

还有这台相机

private void onCaptureImageResult(Intent data) {


   // ????????????
}

?? 我应该写什么请帮助谢谢

`write this piece of code in OnActivityResult()


 1. `if (requestCode == CAMERA) {
                if (data.getExtras().get("data") != null) {
                    bitmap = (Bitmap) data.getExtras().get("data");

                    uri = getImageUri(this, bitmap);

                }
            }



   2. Add this function in the class.
      public Uri getImageUri(Context inContext, Bitmap inImage) {
        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
        String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);// this will give you the path of the image
        return Uri.parse(path);
    }
