答案 0 :(得分:0)
您的代码包含以下内容:
Intent calculatorIntent = new Intent(v.getContext(), calculator.class);
第二个参数应该是活动类名称。您似乎也将计算器实例名称与您正在启动的calculator.class混淆。
我建议如下:
Intent calculatorIntent = new Intent(getBaseContext(), CalculatorActivity.class);
另外为了帮助您,请同时提供LogCat输出。
答案 1 :(得分:0)
你不应该使用
startActivityForResult(calculatorIntent, 0);
而不是以上使用
startActivity(calculatorIntent);
startActivityForResult(calculatorIntent,0); 用于获得您正在开始的活动的结果。如果你只想切换活动,startActivity就足够了。虽然您应该发布logcat以获得更好的答案。
