Question

我的活动中有几个按钮在第一次尝试时没有被点击，但是从第二次开始点击它们。似乎按钮会在第一次点击时获得焦点，并且从第二次开始实际按下按钮。这些按钮第一次没有被点击的原因是什么？我注意到这种行为只能通过我活动最底层的按钮显示。

activity_main.xml中

get

review_card.xml

const jsData = '[{"x":1,"y":1},{"x":2,"y":2}]';
const imData = JSON.parse(jsData)
console.log(imData)
const Rec = Immutable.Record( imData[0])
const rec = new Rec();

console.log(rec.get('x'));

我的MainActivity.class中的代码：

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        View view = findViewById(R.id.sub_layout);
        Button button = (Button) view.findViewById(R.id.button);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //Do your stuff
                Toast.makeText(MainActivity.this, "hi", Toast.LENGTH_SHORT).show();
            }
        });
    }
}

我的activity_main.xml中的代码

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="eflair.myapplication.MainActivity">

    <include
        android:id="@+id/sub_layout"
        layout="@layout/sub_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</android.support.constraint.ConstraintLayout>

我的sub_layout.xml中的代码

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <Button
        android:id="@+id/button"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@string/app_name" />
</LinearLayout>

此问题实际上是public class HomeActivity extends AppCompatActivity implements FragmentChangeListener{ ........ ....... ....... @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.your_layout); Fragment fragment = new Appointment_Fragment(); fragment.fragmentChangeListener = this; Bundle bundle = new Bundle(); fragment.setArguments(bundle); getActivity().getSupportFragmentManager().beginTransaction() .replace(R.id.mainfrag, fragment).commit(); //Always use getChildFragmentManager() for child fragment } @Override public void onFragmentChange(String fragmentName){ if(fragmentName.equals("Appointment_Fragment")){ //do what do you want }else if(fragmentName.equals("FragmentB")){ // do what do you want }else if(fragmentName.equals("FragmentC")){ //do what do you want } } }类中的bug一段时间了。我解决了这个问题，我对NestedScrollView类的源代码进行了一些调整，如下所示： -

NestedScrollView

这样做之后应该可以正常工作。

第一次尝试时没有点击按钮
