一旦应用程序停止从服务器恢复文本,说它现在已被删除,我需要它才能拥有它我需要设置按钮说它已断开连接,这就是我现在所拥有的(这是一个while循环我只是没有发布所有代码)
Thread.sleep(10);
counter++;
if (counter >= 100)
{
Log.d("ClientActivity","send S");
counter = 0;
out.println("S");
A2MCString = in.readLine();
Log.d("ClientActivity","got " + A2MCString);
if (A2MCString == null)
{
connected = false;
Log.d("ClientActivity","Closed1");
Connect.setText("Connect");
Log.d("ClientActivity","Closed2");
Connect.setBackgroundResource(R.drawable.contect_button);
Log.d("ClientActivity","Closed3");
DeBug.setText("Disconnected from " + serverIpAddress);
Log.d("ClientActivity","Closed4");
}
当我尝试设置连接到“连接”时,应用程序崩溃logCat错误是“android.view.ViewRoot $ CalledFromWrongThreadException”如果你可以帮助我那就太棒了!

使用runOnUiThread或处理程序从线程更改UI ..我认为这一行导致错误..
Connect.setBackgroundResource(R.drawable.contect_button);
将它放在你的线程中的runOnUiThread中,就像这样
runOnUiThread(new Runnable() {
public void run() {
Connect.setBackgroundResource(R.drawable.contect_button);
}
});
