主Activity，用来提供文字信息和输入效果ID：

package com.zms.windowfeature;

import org.xml.sax.Parser;

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.view.Menu;

import android.view.MenuItem;

import android.view.View;

import android.view.View.OnClickListener;

import android.view.Window;

import android.widget.Button;

import android.widget.EditText;

import android.widget.TextView;

import android.widget.Toast;

public class Main extends Activity {

private Button btnShow;

private TextView tvNowId;

private EditText etNowId;

@Override

protect
ed void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

btnShow = (Button) findViewById(R.id.btnShow);

btnShow.setOnClickListener(new onClickListenerImp());

tvNowId = (TextView) findViewById(R.id.tvNowId);

etNowId = (EditText) findViewById(R.id.etNowId);

}

public class onClickListenerImp implements OnClickListener {

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

String idStr = etNowId.getText().toString();

int id = Integer.parseInt(idStr);

if ((-5 < id && id < 9 && id != 7) || id == 10000 || id == 20000

|| id == 30000) {

// onCreate(null);

Intent intent = new Intent(Main.this, Show.class);

// intent.setClass(Main.this, Show.class);

intent.putExtra(“idStr”, idStr);

startActivity(intent);

} else if (id == 7) {

Toast.makeText(Main.this, “ID=7:暂未自定义标题栏，无法预览。”,

Toast.LENGTH_SHORT).show();

} else {

Toast.makeText(Main.this, “ID=” + id + “非法,请参考提供文字。”,

Toast.LENGTH_SHORT).show();

}

}

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.main, menu);

return true;

}

@Override

public boolean onOptionsItemSelected(MenuItem item) {

// Handle action bar item clicks here. The action bar will

// automatically handle clicks on the Home/Up button, so long

// as you specify a parent activity in AndroidManifest.xml.

int id = item.getItemId();

if (id == R.id.action_settings) {

return true;

}

return super.onOptionsItemSelected(item);

}

}

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) {

finish();

}

}

文字描述都在主布局文件里面了，也贴上来吧：

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