MainActivity如下:

package cn.com;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.app.Activity;
import android.app.Dialog;
/**
 * Demo描述:

 * 主要手段:
 * 在生成Dialog的时候为其指定一个style
 * 请参见styles.xml文件
 *
 */
public class MainActivity extends Activity {
	private Button mButton;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		init();
	}

	public void init() {
		mButton = (Button) findViewById(R.id.button);
		mButton.setOnClickListener(new ClickListenerImpl());
	}

	private class ClickListenerImpl implements OnClickListener {
		@Override
		public void onClick(View v) {
			switch (v.getId()) {
			case R.id.button:
              showDialog();
				break;
			default:
				break;
			}
		}

	}
	private void showDialog(){
		LayoutInflater inflater=getLayoutInflater(); 
		View dialogView=inflater.inflate(R.layout.test_dialog, null); 
		Dialog dialog=new Dialog(MainActivity.this,R.style.dialog);
		dialog.setContentView(dialogView);
		dialog.getWindow().setLayout(440, LayoutParams.WRAP_CONTENT); 	
		dialog.show();
	}
