思路:
1.監聽u盤插入廣播
2.遍歷指定目錄下的所有文件,找到視頻文件
3.將符合條件的文件加入播放集合中
4.循環播放
num one:
配置AndroidManifest.xml,注冊一個靜態廣播
<receiver android:name="com.android.app.cus.usbdiskplay.MyUsbReceiver" ><intent-filter><action android:name="android.intent.action.MEDIA_MOUNTED" /><action android:name="android.intent.action.MEDIA_REMOVED" /><action android:name="android.intent.action.MEDIA_EJECT" /><data android:scheme="file" /></intent-filter></receiver>
num two:
實現廣播接收者
public class MyUsbReceiver extends BroadcastReceiver {private String TAG=
"MyUsbReceiver";ArrayList<String> as =
new ArrayList<String>();
private boolean isMovieSuffix(Context context,String fileName) {String name=fileName.toLowerCase();String[] suffixs = context.getResources().getStringArray(R.array.video_type_suffix);
for (String string : suffixs) {
if (name.endsWith(string)) {
return true;}}
return false;}
/*** @param action get the receiver* @param uri get the usb's uri* @param testMovieName get the test movie's name*/@Overridepublic void onReceive(Context context, Intent intent) {
final Context mContext = context;String action = intent.getAction();Uri uri = intent.getData();
final String path = uri.getPath();
final String featureFilePath=path+
"/"+context.getResources().getString(R.string.feature_file_name);
if (action.equals(Intent.ACTION_MEDIA_MOUNTED)) {Log.d(TAG,
"~~~~~~~~~~~~~~~~~~~media mounted 111111");
new Thread() {
public void run() {File file =
new File(featureFilePath);
if (file.exists()&&file.isDirectory()) {String[] files = file.list();
for(
int i =
0;i<files.length;i++){String s = files[i];
if(isMovieSuffix(mContext,s)){as.add(featureFilePath+
"/"+s);}} Intent intent=
new Intent(mContext, MainActivity.class);intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);intent.putStringArrayListExtra(
"ff",as);mContext.startActivity(intent);}
else{Log.d(TAG, featureFilePath+
" is not exist.");}}}.start();}}}
array.xml<
string-array
name=
"video_type_suffix"><
item>.rmvb</
item><
item>.mp4</
item><
item>.avi</
item><
item>.wmv</
item><
item>.mkv</
item><
item>.m2ts</
item><
item>
.3gp</
item><
item>.rm</
item></
string-array>
num three:
使用videoview播放as中存放的視頻。
—1
main.xml 就一個videoView控件
<VideoView
android:id="@+id/videoView1"android:layout_width="match_parent"android:layout_height="match_parent" />
mainactivity.java
public class MainActivity extends Activity implements OnCompletionListener,OnErrorListener {private final String TAG=
"MainActivity";
private VideoView videoView;
private ArrayList<String> as;
private Intent intent;
private int i=
0;
@Overrideprotected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);intent = getIntent();as = intent.getStringArrayListExtra(
"ff");requestWindowFeature(Window.FEATURE_NO_TITLE);setContentView(R.layout.activity_main);initView();}
private void initView() {
if (as !=
null) {videoView = (VideoView) findViewById(R.id.videoView1);videoView.setMediaController(
new MediaController(
this));videoView.setOnCompletionListener(
this);videoView.setOnErrorListener(
this);videoView.setVideoURI(Uri.parse(as.get(
0)));videoView.start(); }}
@Overridepublic void onCompletion(MediaPlayer arg0) {Log.d(TAG,
"onCompletion");i++;
if(i<as.size()){videoView.setVideoURI(Uri.parse((as.get(i))));videoView.start();}
else if(i == as.size()){i =
0;videoView.setVideoURI(Uri.parse((as.get(i))));videoView.start();}}
@Overridepublic boolean onError(MediaPlayer mediaPlayer,
int arg1,
int arg2) {Log.d(TAG,
"onError");mediaPlayer.pause();mediaPlayer.stop();finish();
return false;}
@Overrideprotected void onStop() {Log.d(TAG,
"onStop");videoView.pause();
super.onStop();}}
so easy！！！！
