仿蚂蜂窝自由行和慕课网视频欢迎页一.资源准备三个比较短小的视频：视频下载二.开始编写代码1.在项目的res下新建一个raw文件夹，放入准备好的这三个视频2.自定义播放视频的CustomVideoView 在这个自定义View里面提供一个播放视频的方法。用户只需要传入播放路径就可以了，并且可一循环播放。package cn.bluemobi.dylan.welcomevideopager; import android.content.Context; import android.media.MediaPlayer; import android.net.Uri; import android.util.AttributeSet; import an droid.view.View; import android.widget.VideoView; /** * 可以播放视频的View * Created by yuandl on 2016-11-10. */ public class CustomVideoView extends VideoView { public CustomVideoView(Context context) { super(context); } public CustomVideoView(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); } public CustomVideoView(Context context, AttributeSet attrs) { super(context, attrs); } Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); setMeasuredDimension(View.MeasureSpec.getSize(widthMeasureSpec), View.MeasureSpec.getSize(heightMeasureSpec)); } /** * 播放视频 * * param uri 播放地址 */ public void playVideo(Uri uri) { if (uri == null) { throw new IllegalArgumentException("Uri can not be null"); } /**设置播放路径**/ setVideoURI(uri); /**开始播放**/ start(); setOnPreparedListener(new MediaPlayer.OnPreparedListener() { Override public void onPrepared(MediaPlayer mp) { /**设置循环播放**/ mp.setLooping(true); } }); setOnErrorListener(new MediaPlayer.OnErrorListener() { Override public boolean onError(MediaPlayer mp, int what, int extra) { return true; } }); } }3.建立没个欢迎页面的Fragment去加载自定义视频View的视图package cn.bluemobi.dylan.welcomevideopager; import android.net.Uri; import android.os.Bundle; import android.support.annotation.Nullable; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; /** * Created by yuandl on 2016-11-10. */ public class GuildFragment extends Fragment { private CustomVideoView customVideoView; Nullable Override public View onCreateView(LayoutInflater inflater, Nullable ViewGroup container, Nullable Bundle savedInstanceState) { customVideoView = new CustomVideoView(getContext()); /**获取参数，根据不同的参数播放不同的视频**/ int index = getArguments().getInt("index"); Uri uri; if (index == 1) { uri = Uri.parse("android.resource://" getActivity().getPackageName() "/" R.raw.guide_1); } else if (index == 2) { uri = Uri.parse("android.resource://" getActivity().getPackageName() "/" R.raw.guide_2); } else { uri = Uri.parse("android.resource://" getActivity().getPackageName() "/" R.raw.guide_3); } /**播放视频**/ customVideoView.playVideo(uri); return customVideoView; } /** * 记得在销毁的时候让播放的视频终止 */ Override public void onDestroy() { super.onDestroy(); if (customVideoView != null) { customVideoView.stopPlayback(); } } }4.界面布局 5.给界面添加Fragmentpackage cn.bluemobi.dylan.welcomevideopager; import android.os.Bundle; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentManager; import android.support.v4.app.FragmentPagerAdapter; import android.support.v4.view.ViewPager; import android.support.v7.app.AppCompatActivity; import android.view.View; import android.widget.Button; import android.widget.ImageView; import java.util.ArrayList; import java.util.List; public class MainActivity extends AppCompatActivity { private ViewPager vp; private ImageView iv1; private ImageView iv2; private ImageView iv3; private Button bt_start; private List fragments; private void assignViews() { vp = (ViewPager) findViewById(R.id.vp); iv1 = (ImageView) findViewById(R.id.iv1); iv2 = (ImageView) findViewById(R.id.iv2); iv3 = (ImageView) findViewById(R.id.iv3); bt_start = (Button) findViewById(R.id.bt_start); } Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); assignViews(); initData(); initView(); } /** * 初始化数据,添加三个Fragment */ private void initData() { fragments = new ArrayList<>(); Fragment fragment1 = new GuildFragment(); Bundle bundle1 = new Bundle(); bundle1.putInt("index", 1); fragment1.setArguments(bundle1); fragments.add(fragment1); Fragment fragment2 = new GuildFragment(); Bundle bundle2 = new Bundle(); bundle2.putInt("index", 2); fragment2.setArguments(bundle2); fragments.add(fragment2); Fragment fragment3 = new GuildFragment(); Bundle bundle3 = new Bundle(); bundle3.putInt("index", 3); fragment3.setArguments(bundle3); fragments.add(fragment3); } /** * 设置ViewPager的适配器和滑动监听 */ private void initView() { vp.setOffscreenPageLimit(3); vp.setAdapter(new MyPageAdapter(getSupportFragmentManager())); vp.addOnPageChangeListener(new MyPageChangeListener()); } /** * ViewPager适配器 */ private class MyPageAdapter extends FragmentPagerAdapter { public MyPageAdapter(FragmentManager fm) { super(fm); } Override public Fragment getItem(int position) { return fragments.get(position); } Override public int getCount() { return fragments.size(); } } /** * ViewPager滑动页面监听器 */ private class MyPageChangeListener implements ViewPager.OnPageChangeListener { Override public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { } /** * 根据页面不同动态改变红点和在最后一页显示立即体验按钮 * * param position */ Override public void onPageSelected(int position) { bt_start.setVisibility(View.GONE); iv1.setImageResource(R.mipmap.dot_normal); iv2.setImageResource(R.mipmap.dot_normal); iv3.setImageResource(R.mipmap.dot_normal); if (position == 0) { iv1.setImageResource(R.mipmap.dot_focus); } else if (position == 1) { iv2.setImageResource(R.mipmap.dot_focus); } else { iv3.setImageResource(R.mipmap.dot_focus); bt_start.setVisibility(View.VISIBLE); } } Override public void onPageScrollStateChanged(int state) { } } }
