本博客用Android studio集成了vitamio的自定义视频播放器,同时可以在文件管理中选择播放,想要一个自己的视频播放器这边便可以满足
实现具体功能如下:
1.sd卡内存视频文件的点击播放;
2.视频时间进度条;
3.屏幕亮度的手势滑动;
4.视频音量的手势滑动;
5.多点手势效果
6.自定义存储视频url播放
想要的重要的代码,我懂得:
------------------------------软件工程结构图:
最重要的是依赖上vitamio库:
-------------------------工具类FileUtil,检查文件格式是否属于自己定义的格式:
public class FileUtil {
public static final String[] VIDEO_EXTENSIONS = { "3gp", "amv",
"avb", "avd", "avi", "flh", "fli", "flv", "flx", "gvi", "gvp",
"hdmov", "hkm", "ifo", "imovi", "imovi", "iva", "ivf", "ivr",
"m4v", "m75", "meta", "mgv", "mj2", "mjp", "mjpg", "mkv", "mmv",
"mnv", "mod", "modd", "moff", "moi", "moov", "mov", "movie",
"mp21", "mp21", "mp2v", "mp4", "mp4v", "mpe", "mpeg", "mpeg4",
"mpf", "mpg", "mpg2", "mpgin", "mpl", "mpls", "mpv", "mpv2", "mqv",
"msdvd", "msh", "mswmm", "mts", "mtv", "mvb", "mvc", "mvd", "mve",

"vem", "vf", "vfw", "vfz", "vgz", "vid", "viewlet", "viv", "vivo",
"wma"
};
//集合放置所有支持视频格式
private static final List<String> listvideo = new ArrayList<>(
Arrays.asList(VIDEO_EXTENSIONS));
// 检测是否是视频文件
public static boolean isVideo(String path) {
path=getFileExtension(path);
return listvideo.contains(path);
}
// 获取文件后缀名
public static String getFileExtension(String path) {
if (null != path) {
// 后缀点 的位置
int dex = path.lastIndexOf(".");
// 截取后缀名
return path.substring(dex + 1);
}
return null;
}
}--------------------工具类FileUtil,检查文件格式是否属于自己定义的格式:
public class LocUtil {
// 获取所有存储路径
public static List<String> getDirs(Context context) {
List<String> dirs = new ArrayList<String>();
StorageManager storageManager = (StorageManager) context
.getSystemService(Context.STORAGE_SERVICE);
try {
Class[] paramClasses = {};
Method getVolumePathsMethod = StorageManager.class.getMethod(
"getVolumePaths", paramClasses);
getVolumePathsMethod.setAccessible(true);
Object[] params = {};
Object invoke = getVolumePathsMethod.invoke(storageManager, params);
for (int i = 0; i < ((String[]) invoke).length; i++) {
// System.out.println(((String[])invoke)[i]);
dirs.add(((String[]) invoke)[i]);
}
} catch (Exception e) {
e.printStackTrace();
}
return dirs;
}
//获取最大音量
public static int getMaxVolume(Context context) {
return ((AudioManager) context.getSystemService(Context.AUDIO_SERVICE))
.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
}
// 获取当前音量
public static int getCurVolume(Context context) {
return ((AudioManager) context.getSystemService(Context.AUDIO_SERVICE))
.getStreamVolume(AudioManager.STREAM_MUSIC);
}
// 设置当前音量
public static void setCurVolume(Context context, int index) {
((AudioManager) context.getSystemService(Context.AUDIO_SERVICE))
.setStreamVolume(AudioManager.STREAM_MUSIC, index, 0);
}
// 获取屏幕像素
public static ScreenBean getScreenPix(Context context) {
Display dplay = ((VideoPlay) context).getWindowManager()
.getDefaultDisplay();
return new ScreenBean(dplay.getWidth(),dplay.getHeight());
}
}public class ScreenBean {
private int sWidth;
private int sHeight;
public ScreenBean(int sWidth, int sHeight) {
super();
this.sWidth = sWidth;
this.sHeight = sHeight;
}
public int getsWidth() {
return sWidth;
}
public void setsWidth(int sWidth) {
this.sWidth = sWidth;
}
public int getsHeight() {
return sHeight;
}
public void setsHeight(int sHeight) {
this.sHeight = sHeight;
}
}----------------------中转传递界面MainActivity类:
public class MainActivity extends AppCompatActivity {
String Path;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent getPath=getIntent();
String action = getPath.getAction();
if(getPath.ACTION_VIEW.equals(action)){
Path=getPath.getDataString();
}else {
Path= Environment.getExternalStorageDirectory() + "/test.mp4";
}
Intent intent = new Intent(this, VideoPlay.class);
intent.putExtra("videoURL",Path);
startActivity(intent);
finish();
}
}这个界面是中转,开发时一般自己定义,Path=getPath.getDataString();//获取sd卡的视频文件url路径
Path= Environment.getExternalStorageDirectory() + "/test.mp4"; //程序存储的路径,可以扫描手机内存视频存储到数据库,这种视频列表简单自己写.

1.权限:<uses-sdk android:minSdkVersion="7" android:targetSdkVersion="23" /> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
2.注意初始化vitamio的InitActivity:<!-- Don't forgot InitActivity --> <activity android:name="io.vov.vitamio.activity.InitActivity" android:configChanges="orientation|screenSize|smallestScreenSize|keyboard|keyboardHidden|navigation" android:launchMode="singleTop" android:theme="@android:style/Theme.NoTitleBar" android:windowSoftInputMode="stateAlwaysHidden" />3.添加intent隐式意图,对sd卡支持的文件格式添加本程序的打开方式:<activity android:name=".MainActivity"> <intent-filter> <action android:name="android.intent.action.MAIN"/> <category android:name="android.intent.category.LAUNCHER"/> </intent-filter> <intent-filter> <action android:name="android.intent.action.VIEW"></action> <category android:name="android.intent.category.DEFAULT"></category> <data android:mimeType="video/*"/> <data android:mimeType="application/mp4"/> <data android:mimeType="*/rmvb"/> <data android:mimeType="*/avi"/> <data android:mimeType="*/mkv"/> <data android:mimeType="audio/x-pn-realaudio"/> <data android:mimeType="video/x-ms-asf"/> <data android:mimeType="video/quicktime"/> <data android:mimeType="application/mpeg*"/> <data android:mimeType="application/vnd.rn-realmedia*"/> <data android:mimeType="application/3gpp*"/> <data android:mimeType="application/vnd.3gp*"/> <data android:mimeType="application/vnd.dvb*"/> <data android:mimeType="application/vnd.dolby*"/> <data android:mimeType="application/octet-stream"/> </intent-filter> </activity>4.添加视频播放控制的Activity:<activity android:name=".VideoPlay" android:screenOrientation="landscape" > </activity>
