Android 将位图文件(杯状图像)转换为路径文件
photo参数是位图,我检查了它,它显示了cuptured图像 如何将位图转换为路径,以便能够作为附件发送到邮件 代码如下:Android 将位图文件(杯状图像)转换为路径文件,android,image,email,Android,Image,Email,photo参数是位图,我检查了它,它显示了cuptured图像 如何将位图转换为路径,以便能够作为附件发送到邮件 代码如下: protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.opencvhc); ImgPhoto = (ImageView) findViewById(R.id.ImgPhoto)
