怎样对layout进行移动并且 addView

Layout 调用 layoutlayout(int l, int t, int r, int b) 方法后变换了位置
但是在调用了 addView 方法后位置又变了回去
AndroidTestDemoActivity.java

package com.view.demo;



import android.app.Activity;

import android.os.Bundle;

import android.view.LayoutInflater;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.FrameLayout;



public class AndroidTestDemoActivity extends Activity {

	private Button bt, bt2;

	private FrameLayout layout;

	private FrameLayout container;

	

    /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        

        bt = (Button) findViewById(R.id.button);

        bt.setOnClickListener(new OnClickListener() {

			

			public void onClick(View v) {

				// TODO Auto-generated method stub

				layout.layout(80, 0, 80 + layout.getWidth(), layout.getHeight());

				layout.postInvalidate();

			}

		});

        bt2 = (Button) findViewById(R.id.button2);

        bt2.setOnClickListener(new OnClickListener() {

			

			public void onClick(View v) {

				// TODO Auto-generated method stub

				layout.addView(LayoutInflater.from(AndroidTestDemoActivity.this).inflate(R.layout.view, null));

			}

		});

        layout = (FrameLayout) findViewById(R.id.layout);

        container = (FrameLayout) findViewById(R.id.container);

    }

}

main.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:orientation="vertical" >



    <Button android:id="@+id/button"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:text="Layout" />

    

    <Button android:id="@+id/button2"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:text="AddView" />

    

    

    <FrameLayout android:id="@+id/layout"

        android:layout_width="fill_parent"

        android:layout_height="fill_parent"

        android:background="#ff00ff00" >

        

        <FrameLayout android:id="@+id/container"

        android:layout_width="fill_parent"

        android:layout_height="fill_parent"

        android:background="#ff00ff00" />

        

	</FrameLayout>



</LinearLayout>

view.xml
[code=XML]<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="@android:color/white" >

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/hello" />

</LinearLayout>/code]
