修改方法：
将更新UI代码加入到activity的UI线程队列中
??? /*<Hap5.2 Message+ kf55773 2012-06-15 begin */
??? private void updateTypingIcon(final boolean aEnableTyping) {
??? ??? ComposeMessageActivity.this.runOnUiThread(new Runnable() {
??? ??? ??? public void run() {
??? ??? ??? ??? if (null == mTypingIcon) {
??? ??? ??? ??? ??? /* modified by Message+ kf36922 20120207 begin */
??? ??? ??? ??? ??? mTypingIcon = (GifView) findViewById(R.id.typing);
??? ??? ??? ??? ??? /* modified by Message+ kf36922 20120207 end */
??? ??? ??? ??? }
??? ??? ??? ??? if (aEnableTyping) {
??? ??? ??? ??? ??? mTypingIcon.setVisibility(View.VISIBLE);
