public void onClick(View v) {
Toast.makeText(MainActivity.this,"You taped!",Toast.LENGTH_SHORT).show();
try {
startActivity(new Intent(MainActivity.this, FuelChoiceActivity.class));
}catch (Exception e){
System.out.println(e);
}
}
这是我的代码。我已将新的活动添加到我的manifest.xml中。 try/catch块没有返回任何示例。当我按下按钮时，执行并显示吐司，但页面不变。这个onClickListener在一个适配器方法'getView'中，所以它可以通过适配器生成的任何按钮来获得。我尝试了其他事件，他们工作！唯一没有的是去新的活动。意图不开始新的活动
这里是我的日志当我调试，并点击一个按钮：

感谢您的阅读和你的时间。我会欣赏想法。
您是否在FuelChoiceActivity的onCreate中获得了任何记录器 –
如果我们对FuelChoiceActivity有访问权限，我们可以更好地了解这个问题 – nandsito
FuelChoiceActivity只有基本的onCreate和东西。如果我将它作为主要工具启动它。唯一的区别是我的主要活动扩展了Activity，FuelChoiceActivity扩展了AppCompatActivity。第二个没有日志 –
