Question

我想进行相同的活动，例如MainActivity-＆gt; MainActivity而不是MainActivity-＆gt; SecondActivity

她是我的代码，但它不起作用，它会停止我的应用程序，如何解决它

    ]
  }
}

Answer 1

我想你想刷新我们的活动，试试这个

finish();
startActivity(getIntent());

或试试这个

Intent intent = getIntent();
    finish();
    startActivity(intent);

Answer 2

尝试

Intent intent = new Intent(FriendDetailsActivity.this, FriendDetailsActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);

Answer 3

您可以调用方法

  recreate();
