我怎样才能做到这一点？

How can I do that?

按钮点击：

mycontext.finish();

和则：再次启动

推荐答案

您可以尝试两种这样的：

You could try either this:

MyActivity.finish()
Intent intent = new Intent(MyActivity.this, MyActivity.class);
startActivity(intent);

或者，如果不工作，你可以这样做：

Or if that doesn't work, you could do this:

private boolean isRestarting = false;
...
// When button is pressed
isRestarting = true;
myactivity.finish();
...
// in the onDestroy() method
if(isFinishing() && isRestarting){
    Intent intent = new Intent(MyActivity.this, MyActivity.class);
    startActivity(intent);
}
