我在content_main.xml中有Imagebotton,代码为:
var buf = '';
req.on('data', function(data) {
// Here `data.toString()` is called implicitly because you a
// non-string object has to be converted somehow in order to be
// added to `buf`. When this implicit conversion happens, the result
// will be the concatenation of `buf` + `data` converted to a UTF-8
// string because that is the default encoding argument for
// `buffer.toString()`
buf += data;
// You can even check that it's a buffer with:
console.log(Buffer.isBuffer(data));
});
并显示:
但我希望imageBotton没有框效果,例如:
而且,我将使这个imageBotton转到下一个布局
我该怎么办?

您的图片似乎比提供的尺寸大。如果使用wrap_content,则可以看到整个图像,而不是固定的高度和宽度。像这样:
public class Node1 {
String lname;
String fname;
int age;
Node1 lChild;
Node1 rChild;
public Node1( String l, String f, int a)
{
this.lname = l;
this.fname = f;
this.age = a;
lChild = null;
rChild = null;
}
public String toString()
{
return(" the age for "+fname+" "+ lname +" is "+ age);
}
}
如果您希望图像没有框效果,可以尝试添加透明背景的图像。
