有时候,我们在线程里面需要弹框,然而在用Toast弹框后,会出一个Can't create handler inside thread that has not called Looper.prepare() 错误。。。。原因很简单就是因为安卓界面更新的操作需要在主线程操作.
实现的具体代码:
Thread thd = new Thread(new Runnable() {
public void run() {
try {
boolean isSussess = con(str);//上传照片到服务器端
Looper.prepare();
if (isSussess == true) {
Toast.makeText(getBaseContext(), "图片上传成功!",
Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getBaseContext(), "图片上传失败!",
Toast.LENGTH_LONG).show();
}
Looper.loop();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
thd.start()
