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);

}

}

android:id="@+id/linearlayout"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:orientation="horizontal" >

android:id="@+id/button2"

android:layout_width="80px"

android:layout_height="80dp"

android:text="Button" />
