Code Fragment-Android在其他线程可以使用方法在UI线程执行UI相关

方法便是activity.runOnUiThread

activity.runOnUiThread(new Runnable() {    public void run() {        new AlertDialog.Builder(activity)            .setIcon(android.R.drawable.ic_dialog_alert)            .setTitle(R.string.error_state)            .setMessage(msg + "\n\n" + activity.getString(R.string.error_state_text))            .setPositiveButton(R.string.yes, new OnClickListener() {               public void onClick(DialogInterface dialog, int which) {                   dialog.dismiss();               }             })            .show();    }});
