//异步处理的代码
@SuppressLint("HandlerLeak")
private Handler handler = new Handler() {
public void handleMessage(Message msge) {
switch (msge.what) {
case ISLOGIN:
// 在这里可以进行UI操作
Toast.makeText(LoginActivity.this, "account or password is invalid",
Toast.LENGTH_SHORT).show();

}
}
};
注意:重新开启一个线程处理HttpClient请求,不要在UI线程处理,注意编码方式,如果出现乱码,数据库插入操作失败,将返回null值。
