android花屏效果的實現(ViewPager的基本使用)

1、程序運行效果圖

二、代碼實現

1、main.xml

2、tab1.xml、tab2.xml、tab3.xml

3、MainActivity

package com.njupt.viewpagertest3;

import java.util.ArrayList;
import java.util.List;

import android.os.Bundle;
import android.app.Activity;
import android.support.v4.view.PagerAdapter;
import android.support.v4.view.PagerTitleStrip;

import android.view.LayoutInflater;
import android.view.Menu;
import android.view.View;
import android.view.ViewGroup;

public class MainActivity extends Activity {

	private ViewPager viewPager;
	private PagerTitleStrip pagerTitleStrip;//表示滑動的每一頁的標題
	private List list;//表示裝載滑動的布局
	private List titlelist;//表示滑動的每一頁的標題...
	
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		viewPager = (ViewPager) findViewById(R.id.viewpager);

		titlelist = new ArrayList();
		titlelist.add("章澤天1");

		viewPager.setAdapter(new MyAdapter());
		
	}

	public class MyAdapter extends PagerAdapter{

		@Override

		}

		@Override

		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}
