解决方案

您似乎已经在onClick事件处理程序中更改了按钮文本。如果您正在使用某些方法调用来播放所需的声音，您也可以将其放入您的onClick处理程序方法中。例如：

public void onClick(View v) {
    String ButtonText=one.getText().toString();
    // method call that plays the sound
    if(ButtonText.equals("Stop")){
        one.setText("Play");
    } else {
        one.setText("Stop");
    }
}
