我的应用程序中有一个ImageView,我希望它在点击时打开某个网站。我很确定我做的一切都很正确,但它仍然行不通。单击ImageView后,应用程序崩溃。
ImageView banner = (ImageView)findViewById(R.id.banner);
banner.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent openUrl = new Intent();
openUrl.setAction(Intent.ACTION_VIEW);
openUrl.addCategory(Intent.CATEGORY_BROWSABLE);
openUrl.setData(Uri.parse("www.google.com"));
startActivity(openUrl);
}
});

编辑:
String url = "www.google.com";
if (!url.startsWith("http://") && !url.startsWith("https://"))
{
url = "http://" + url;
}
else
{
Intent openUrl = new Intent();
openUrl.setAction(Intent.ACTION_VIEW);
openUrl.addCategory(Intent.CATEGORY_BROWSABLE);
openUrl.setData(Uri.parse(url));
startActivity(openUrl);
}

您想在浏览器窗口中打开网站吗?如果是,请删除CATEGORY。我很确定这只适用于WebViews。
