AlertDialog.Builder.setView与AlertDialog.setView

Question

这些方法有什么区别吗？我想首先创建对话框，以便在视图中单击某些内容时将其引用以解除它。显然，如果我使用构建器设置视图并且尚未创建警报，那是不可能的。

Answer 1

根据AlertDialog.Builder source，它没有任何区别。

Answer 2

  

“我想首先创建对话框，以便我可以参考   当在视图中点击某些内容时将其关闭。“

在您向对象显示对话之前，用户无法单击以关闭对话框，这是在您创建实例之后。请参阅下面的生命周期示例：

    View someView = ...;
    View someOtherView= ...;

    AlertDialog.Builder builder = new AlertDialog.Builder(this);

    //sets the view, but doesn't show anything.     
    builder.setView(someView);  

    //now we have an instance of AlertDialog, still not shown
    AlertDialog dialog = builder.create();

    //now we showed it
    dialog.show();

    //...(wait some time)
    //now we changed its view after being shown
    dialog.setView(someOtherView);
