我遇到了与textbar相关的问题，并且收到了以下消息。由于以下原因，我所处理的是：1）尝试将用户记录的搜索栏值信息存储到解析中以便以后能够检索它。存储EditText（如姓名，年龄，标题和radiobox，如性别）可以正常工作，但是当我包含应用程序无法运行的搜索时。
我尝试过清理项目，并使用“正确的前缀”重写ID，例如sb用于搜索栏，而tv用于textview。
以下是logcat消息：

答案 0 :(得分：3)
您的XML已将tvseekBarDistanceValue定义为TextView，而不是SeekBar。由于您正在尝试将TextView更改为SeekBar（这是不可能的），因此您收到此错误。
根据您的XML，我认为您要替换
seekBarDistance = (SeekBar) findViewById(R.id.tvseekBarDistanceValue);
与
seekBarDistance = (SeekBar) findViewById(R.id.sbseekBarDistance);
