Show Activity，接收Main传来的数，用来显示对应的预览效果：
package com.zms.windowfeature; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.View; public class Show extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); Intent intent = getIntent(); String idStr = intent.getStringExtra(“idStr”); int id = Integer.parseInt(idStr); requestWindowFeature(id); setContentView(R.layout.show); } public void Back(View v) {
