当单击一个按钮时,我使用简单的线程来执行httpGet到服务器,但是我在执行后得到了这个.
Button b_back = (Button) findViewById(R.id.bback);
b_back.setOnClickListener(this);
Button b_sign_up = (Button) findViewById(R.id.signup_button);
b_sign_up.setOnClickListener(this);
@Override
public void onClick(View arg0)
{
// TODO Auto-generated method stub
switch (arg0.getId())
{
case R.id.bback:
Intent i = new Intent(this, MainSwitch.class);
finish();
startActivity(i);
break;
// More buttons go here (if any) ...
case R.id.signup_button:
if(username.getText().toString().equalsIgnoreCase("") ||
password.getText().toString().equalsIgnoreCase("") ||
email.getText().toString().equalsIgnoreCase(""))
{
AlertDialog.Builder dialog = new AlertDialog.Builder(this);
dialog.setMessage("Please fill in all the gaps!");
dialog.show();
}
else
{
//****** Call method that sends the information to server.
