我有一个带按钮的活动。在ACTION_DOWN上，我按下此按钮开始录制并继续录制。在ACTION_UP我必须停止录音。录制线程是独立的。活动上有一个文本视图，显示录制时间。 时间的默认值是“00：00：00：000” 从录制线程我调用活动类的updateTime方法：
public void updateTime(final String time) {
Log.d("***UPDATE TIME Thread", "Current time:" + time);
runOnUiThread(new Runnable() {
public void run() {
timerTextView.setText(time);
Log.d("UPDATE TIME Thread", "Current time:"+time);
}
});
}
当我第一次调用此活动时，它可以正常工作并正确更新时间值。但是，如果我从前一个屏幕选择相同的选项以开始第二次记录，则时间文本视图的值保持与“00：00：00：000”相同，其中显示正确值的第二个Log.d代码行。这是LogCat
