我想知道LayoutParams它将如何运作LayoutInflator.有什么区别:

LinearLayout childLayout=(LinearLayout)inflater.inflate(R.layout.childitemlayout, null); //FIRST WAY
LinearLayout childLayout=(LinearLayout)inflater.inflate(R.layout.childitemlayout, container,false); //SECOND WAY

因为,这两种方法都给我不同的结果.实际上第二次充气方法给了我两个子布局改变的正确结果,但是第一种方法会给我不同的结果.

这是我的代码:

MainActivity.Java

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        LinearLayout mainLayout=(LinearLayout)findViewById(R.id.mainLayout);
        LayoutInflater inflater=LayoutInflater.from(getApplicationContext());
        for(int i=0;i<10;i++){
            LinearLayout childLayout=(LinearLayout)inflater.inflate(R.layout.childitemlayout, null); //First WAY
//          LinearLayout childLayout=(LinearLayout)inflater.inflate(R.layout.childitemlayout, mainLayout,false);  //SECOND WAY
            mainLayout.addView(childLayout);
        }
    }


main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/mainLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >

</LinearLayout>


childitemlayout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="80dp"
    android:layout_height="80dp"
    android:orientation="vertical" 
    android:background="#525f67">

    <TextView android:id="@+id/btn"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:text="Button"
            android:gravity="center"
            />


</LinearLayout>  <!-- Both ways gives …
