我想从我的URL中获取图像并将其添加到进一步添加到广播组的单选按钮。但是,我找不到像setText这样的metod来设置单选按钮的文本。我希望以类似的方式将图像添加到我的单选按钮。是否有任何提示/方法可以为我做同样的事情?任何提示/代码示例都对我有用,
RadioGroup rg = new RadioGroup (this);
rg = (RadioGroup) findViewById(R.id.radioGroup1);
RadioButton rb[]= new RadioButton[children.size()];
for (int i = 0; i < var.size(); i++)
{
Element movieAtt = (Element)doc.getRootElement().getChild("movies").getChildren("movie").get(i);
MovieName[i]=movieAtt.getAttributeValue( "Title" );
MovieCover[i]=movieAtt.getAttributeValue( "cover" );
ShowTime[i]=movieAtt.getAttributeValue( "showtime" );
rb[i] = new RadioButton(this);
rb[i].setText(movieAtt.getAttributeValue("Title"));
rg.addView(rb[i]);
//Calling this func to get Images
//LoadImageFromWebOperations(movieAtt.getAttributeValue( "cover" ));
//rb[i].buildDrawingCache(LoadImageFromWebOperations(movieAtt.getAttributeValue( "cover" )));
public static Drawable LoadImageFromWebOperations(String url)
{
try
{
InputStream is = (InputStream) new URL(url).getContent();
Drawable d = Drawable.createFromStream(is, "src name");
return d;
}
catch (Exception e)
{
return null;
}
}
答案 0 :(得分:1)
图像或文字有问题吗?至于图像,我相信这应该有效:
Drawable d = LoadImageFromWebOperations(movieAtt.getAttributeValue("cover"));
rb[i].setButtonDrawable(d);
确保将重力设置为Gravity.CENTER
,否则您的图像将不会以单选按钮为中心。
您应该在RadioButton reference中找到有关该文本的信息。
