出于某种原因，我的搜索活动正在运行，但thumbsup活动无法启动。它承认我说“三”然后我的应用程序崩溃。我需要在这里添加什么才能使其正常工作？
在添加此部分之前，应用程序运行良好：
if (textMatchList.get(0).contains("three")) {
// create an intent indicating we want
// to start the ThumbsUp activity.
// Important! Make sure your activity is
// in the AndroidManifest.xml file!
Intent i = new Intent(this, ThumbsUp.class);
// start the activity based on the Intent
startActivity(i);
logcat的：
