如何获得线性布局的子对象的位置？

Question

This is my xml :

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:gravity="top"
    android:rotation="180">

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:layout_gravity="center"
        android:id="@+id/cols">

        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            android:id="@+id/col1">
            <Button .../>
            <Button .../>
            <Button .../>
            <Button .../>
            <Button .../>
            <Button .../>
        </LinearLayout>

        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            android:id="@+id/col2">
            <Button .../>
            <Button .../>
            <Button .../>
            <Button .../>
            <Button .../>
            <Button .../>
        </LinearLayout>

    </LinearLayout>
</LinearLayout>

Try this logic:

In your activity, do this:

LinearLayout layout = findViewById(R.id.col1);

then, in every buttons's onClick :

for(int i=0; i<layout.getChildCount(); i++) {
    if(layout.getChildAt(i).equals(thisButton))//Replace thisButton with the variable name
    {
        //do something
        // i  represents the button's position in its immediate parent.
        break;
    }
}            

The same logic can also apply for the LinearLayout col2
