Java OnClick侦听器未按预期运行
我在Java OnClick侦听器未按预期运行,java,android,onclick,switch-statement,onclicklistener,Java,Android,Onclick,Switch Statement,Onclicklistener,我在TextView（mReadAgainButton）上设置了一个onClickListener，它应该从一开始就重新加载一组指令（最初通过onClickListener在名为mAssistUpdateButton的按钮上显示）但是，当单击TextViewmReadAgainButton时，似乎什么也没有发生 public void onClick(View v) { if (v == mAssistUpdateButton) { // Update
