Android--取得布局中指定控件的宽高

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;

public class GetWH extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        View view = getLayoutInflater().inflate(R.layout.main, null);
        Button button = (Button) view.findViewById(R.id.button2);
        int width = button.getLayoutParams().width;
        int height = button.getLayoutParams().height;
        Log.i("System.out", width + "-----" +  height);
    }
}

 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/linearlayout"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal" >
    <Button
        android:id="@+id/button2"
        android:layout_width="80px"
        android:layout_height="80dp"
        android:text="Button" />
</LinearLayout>

 

从结果中大家可以看出些什么呢？
