最满意答案

如果Activity在堆栈中，那么您可以使用它

Intent resultIntent = new Intent(ActivityB.this,ActivityC.class); resultIntent.setFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT) startActivity(resultIntent);

If you Activity is in stack then you can use this

Intent resultIntent = new Intent(ActivityB.this,ActivityC.class); resultIntent.setFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT) startActivity(resultIntent);
