java - 如何以编程方式复制添加 subview 的View布局？

我的MainActivity是通过水平方向设置的，它包括2个Framelayout。

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    android:weightSum="1"
    tools:context="com.example.helloandroid.MainActivity" >

    <FrameLayout
        android:id="@+id/framelayout1"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_weight="0.5" >
    </FrameLayout>

    <FrameLayout
        android:id="@+id/framelayout2"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_weight="0.5" >
    </FrameLayout>

</LinearLayout>

从MainActivity.java中，frameLayout1以编程方式添加一些按钮，这些按钮通过以下代码设置为随机位置：

private void addNumbers(){ // Numbers is set with random position

    for (int i = 1; i < 3; i++) {
        Button btn = new Button(this);
        btn.setText("" + i);
        btn.setId(i);

        FrameLayout.LayoutParams lp = new FrameLayout.LayoutParams(50, 50);
        int leftMargin = new Random().nextInt(widthScreen/2 - btnSize );
        int topMargin = new Random().nextInt(heightScreen - btnSize);
        lp.leftMargin = leftMargin;
        lp.topMargin = topMargin;

        btn.setLayoutParams(lp);
        framelayout1.addView(btn);
        //framelayout2.addView(btn);

    }
}

我想使framelayout2具有与framelayout1相同的布局，如下图所示


那么，如何将framelayout1的布局复制到framelayout2？
以及如何识别按钮的onclick事件在framelayout1或framelayout2上？

最佳答案

尝试遵循以下示例代码，

private void addNumbers(){ // Numbers is set with random position
    for (int i = 1; i < 3; i++) {
        Button btn1 = new Button(this);
        Button btn2 = new Button(this);
        btn1.setOnClickListener(listener1);
        btn2.setOnClickListener(listener2); // here using different listener
        btn1.setText("" + i);
        btn2.setText("" + i); //same text

        FrameLayout.LayoutParams lp = new FrameLayout.LayoutParams(50, 50);
        int leftMargin = new Random().nextInt(widthScreen/2 - btnSize );
        int topMargin = new Random().nextInt(heightScreen - btnSize);
        lp.leftMargin = leftMargin;
        lp.topMargin = topMargin;

        btn1.setLayoutParams(lp);
        btn2.setLayoutParams(lp); //same lp

        framelayout1.addView(btn1);
        framelayout2.addView(btn2);
    }
}
