我是新的Andr​​oid开发，寻找指定图像的src图像视图控件的方式。我看了几个例子，他们说了些什么 SRC =@可绘制\图像，但不明白这一点，我也想在Java $ C $指定图像的src在运行时C也想申请默认图像以XML。

I am new to android development, looking for the way to assign image src to image view control. I read few example and they says something src="@drawable\image" but didn't understand this, also I want to assign image src at runtime by java code also want to apply default image in XML.

感谢

如果你想显示在手机上的图像文件，你可以这样做：

If you want to display an image file on the phone, you can do this:

private ImageView mImageView;
mImageView = (ImageView) findViewById(R.id.imageViewId);
mImageView.setImageBitmap(BitmapFactory.decodeFile("pathToImageFile"));

如果你想从你绘制资源，显示图像，做到这一点：

If you want to display an image from your drawable resources, do this:

private ImageView mImageView;
mImageView = (ImageView) findViewById(R.id.imageViewId);
mImageView.setImageResource(R.drawable.imageFileId);

您会发现绘制文件夹中的项目 RES 文件夹（S）。你可以把你的图像文件存在。

You'll find the drawable folder(s) in the project res folder. You can put your image files there.
