本文主要介绍如何将音乐文件打包到程序中并设置为铃声

canon.mp3文件放到raw目录下

 

 

然后在程序里读取这个文件：

代码为

view plaincopy to clipboardprint?
getResources().openRawResource(R.raw.canon);  
getResources().openRawResource(R.raw.canon); 

然后将读出的内容写到sdcard上

 

 

程序能直接把sdcard上的一个文件设置为铃声。

 

具体的实现代码如下

 

setring.java

view plaincopy to clipboardprint?
package zy.ring; 
import java.io.File; 
import java.io.FileOutputStream; 
import java.io.IOException; 
import java.io.InputStream; 
import android.app.Activity; 
import android.content.ContentValues; 
import android.media.RingtoneManager; 
import android.net.Uri; 
import android.os.Bundle; 
import android.provider.MediaStore; 
import android.util.Log; 
import android.widget.Toast; 
public class setring extends Activity { 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState); 
        setContentView(R.layout.main); 
        InputStream inputStream = null;   
        
        try {   
            inputStream = getResources().openRawResource(R.raw.canon);   
            byte[] reader = new byte[inputStream.available()];   
            while (inputStream.read(reader) != -1) {}   
            writefile(reader,"/sdcard/canon.mp3"); 
            Log.i("setring", "success"); 
        } catch(IOException e) {   
            Log.i("setring", e.getMessage());   
        } finally {   
            if (inputStream != null) {   
                try {   
                    inputStream.close();   
                } catch (IOException e) {   
                    Log.i("setring", e.getMessage());   
                }   
            }   
        }   
         
         setMyRingtone(); 
         
    }   
    public void writefile(byte[] str,String path ) 
    {
