Question

我想检查是否在imageview中选择了图像是否已经使用了

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    if(requestCode==REQUEST_PICK_IMAGE && resultCode==RESULT_OK){

        path = data.getStringExtra(Constants.path);

        isImageSet=true;

        File imgFile=new File(path);
        path =imgFile.getPath();

        Glide.clear(ivIdProof);

        bitmap = BitmapFactory.decodeFile(path);
        bitmap= ImageHandling.loadBitmapFromFile(this, path,400,400);
        ivIdProof.setImageBitmap(bitmap);

    }

    super.onActivityResult(requestCode, resultCode, data);


}

非常棒的验证码

 awesomeValidation.addValidation(this, R.id.etIdentity, "^[A-Za-z\\s]{1,}[\\.]{0,1}[A-Za-z\\s]{0,}$", R.string.error_id1);
 awesomeValidation.addValidation(this, R.id.etIdentityNumber, "^[A-Za-z0-9\\s]{1,}[\\.]{0,1}[A-Za-z0-9\\s]{0,}$", R.string.error_id2);

并检查

if(awesomeValidation.validate() && path!=null){
.....
}

awesomeValidation.validate()用于验证其他字段。如何使用awesome验证检查path!=null并显示错误消息

Answer 1

试试这个：

'file' => 'required|max:5128'; // max file size: 5M

Answer 2

您可以尝试以下操作：

rstrip()

现在来自您的代码：

    private boolean isImagePathValid(String path) {
    BitmapFactory.Options options = new BitmapFactory.Options();
    options.inJustDecodeBounds =true;
    Bitmap bitmap = BitmapFactory.decodeFile(path, options);
    if(options.outWidth !=-1&&options.outHeight !=-1)
    {
        return true;
    }
    else
    {
        return false;
    }
}

..... }

非常好的验证来验证imageview
