1. Android MediaPlayer and VideoView Tutorial
A. Create a Project
1. 設定好專案相關資料後 > Next
> Next
B. Create raw folder to store video files
1. res > New > Directory
C. Design the Interface:
1. 點選 activity_main.xml 檔案, 將右方 Component Tree 下的元件,
只留一個預設的 RelativeLayout, 其餘皆刪除.
將其 layout:width 與 layout:height 皆設為: fill_parent
5. activity_main.xml 完成如下:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="cat.myhome.videoplayer.MainActivity">
<VideoView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/videoView"
android:layout_gravity="center" />
</FrameLayout>
D. 開啟 MainActivity.java 檔案, 修改如下:
package cat.myhome.videoplayer;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
//@VideoPlayer ------
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnPreparedListener;
import android.widget.MediaController;
import android.net.Uri;
import android.util.Log;
import android.widget.VideoView;
public class MainActivity extends AppCompatActivity {
//@VideoPlayer ------
private VideoView videoView;
private int position = 0;
private MediaController mediaController;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//@VideoPlayer ------
videoView = (VideoView) findViewById(R.id.videoView);
//@VideoPlayer: Set the media controller buttons ------
if (mediaController == null) {
mediaController = new MediaController(MainActivity.this);
// Set the videoView that acts as the anchor for the MediaController.
mediaController.setAnchorView(videoView);
// Set MediaController for VideoView
videoView.setMediaController(mediaController);
}
//@VideoPlayer: Set the Video URI ------
try {
// ID of video file.
int id = this.getRawResIdByName("alice");
videoView.setVideoURI(Uri.parse("android.resource://" + getPackageName() + "/" + id));
} catch (Exception e) {
Log.e("Error", e.getMessage());
e.printStackTrace();
}
videoView.requestFocus();
//@VideoPlayer: When the video file ready for playback. ------
videoView.setOnPreparedListener(new OnPreparedListener() {
public void onPrepared(MediaPlayer mediaPlayer) {
videoView.seekTo(position);
if (position == 0) {
videoView.start();
}
// When video Screen change size.
mediaPlayer.setOnVideoSizeChangedListener(new MediaPlayer.OnVideoSizeChangedListener() {
@Override
public void onVideoSizeChanged(MediaPlayer mp, int width, int height) {
// Re-Set the videoView that acts as the anchor for the MediaController
mediaController.setAnchorView(videoView);
}
});
}
});
} // end of: onCreate
//@VideoPlayer: Find ID corresponding to the name of the resource (in the directory raw). ------
public int getRawResIdByName(String resName) {
String pkgName = this.getPackageName();
// Return 0 if not found.
int resID = this.getResources().getIdentifier(resName, "raw", pkgName);
Log.i("AndroidVideoView", "Res Name: " + resName + "==> Res ID = " + resID);
return resID;
}
//@VideoPlayer ------
// When you change direction of phone, this method will be called.
// It store the state of video (Current position)
@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
super.onSaveInstanceState(savedInstanceState);
// Store current position.
savedInstanceState.putInt("CurrentPosition", videoView.getCurrentPosition());
videoView.pause();
}
//@VideoPlayer ------
// After rotating the phone. This method is called.
@Override
public void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
// Get saved position.
position = savedInstanceState.getInt("CurrentPosition");
videoView.seekTo(position);
}
} // end of: class MainActivity
-----------------------------------------------------------------------------------------------
E. 執行結果:
-----------------------------------------------------------------------------------------------
F. Playing Video from URL:
1. Declare permission to access Internet
AndroidManifest.xml:
....
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<application>
....
2. MainActivity.java
....
// Way 1:
String videoUrl="http://www.youtubemaza.com/files/data/366/Tom%20And%20Jerry%20055%20Casanova%20Cat%20(1951).mp4";
Uri video = Uri.parse(videoUrl);
videoView.setVideoURI(video);
// Way 2:
String videoUrl="http://www.youtubemaza.com/files/data/366/Tom%20And%20Jerry%20055%20Casanova%20Cat%20(1951).mp4";
videoView.setVideoPath(videoUrl);
....
