ERROR:Only the original thread that created a view hierarchy can touch its views. Android更新UI

当出现:Only the original thread that created a view hierarchy can touch its views.时,意思是无法在子线程中更新UI,是由于子线程更新了主线程,抛出的错误又或者在别一个类中,引用了主线程的 invalidate()方法。
解决方法:如果在另一个类中,引用主线程的想刷新界面应该用: postInvalidate()方法,另一种方法是用handler方法,
还有一种是runOnUiThread方法。
前2种方法的使用实例参考博文http://blog.csdn.net/veryitman/article/details/6384641
runOnUiThread方法使用如下:private OnClickListener mListener2 = new View.OnClickListener() { public void onClick(View v) { getActivity().runOnUiThread(new Runnable() { @Override public void run() { // This code will always run on the UI thread, therefore is safe to modify UI elements. myTextBox.setText("my text"); } }); } };
