Question

我正在研究android fragments。在我的应用中，我遇到了activity和fragment的问题。即我在button中创建了fragment1，并在activity1点击中调用button。我再次在activity1中创建了另一个button并调用activity2。现在从activity2我致电activity1和activity1，我试着致电fragment1。但它在id上显示错误（任何人都可以告诉我我们需要提供哪个ID）。我在谷歌研究如何从fragment拨打activity，但我没有找到任何解决方案。请帮我解决这个问题。提前谢谢。

我的代码：

Activity1.class

public void back(View v) {

 MyFragment1 fragmentS1 = new MyFragment1();
 getFragmentManager().beginTransaction().replace(android.R.id.frame_container, fragmentS1).commit();

}

Answer 1

试试这个..

从此android.R.id.frame_container

中删除android

如果您使用activity1 延伸 Activity使用getFragmentManager()，或者如果您使用activity1 延伸 { {1}}使用FragmentActivity。

如下所示

getSupportFragmentManager()

Answer 2

Fragment frag;
FragmentManager fm1 = MainActivity.this
    .getSupportFragmentManager();
FragmentTransaction ft1 = fm1.beginTransaction();
frag = new Animal_Activity();
ft1.replace(R.id.activity_main_content_fragment, frag);
ft1.commit();

Answer 3

将其写入您的活动，如下所示

Fragment fragment = new YourFragment();
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.replace(R.id.output1, fragment);
transaction.addToBackStack(null);
transaction.commit();

Answer 4

这样做： -

FragmentManager fragmentManager = getFragmentManager();
            FragmentTransaction fragmentTransaction = fragmentManager
                    .beginTransaction();
            MyFragment1 fragmentS1 = new MyFragment1();
            fragmentTransaction.replace(R.id.realtabcontent, mBarcodeScreen);
            fragmentTransaction.commit();

祝你好运!!

Answer 5

只需你可以这样打电话：

$("#form-id").submit(function(){

    your function;

});

如何从android中的活动调用片段？
