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 )
{
File file;
FileOutputStream out;
try {
//创建文件
file = new File(path);
file.createNewFile();
//打开文件file的OutputStream
out = new FileOutputStream(file);
//将字符串转换成byte数组写入文件
out.write(str);
//关闭文件file的OutputStream
out.close();
} catch (IOException e) {
//将出错信息打印到Logcat
DisplayToast(e.toString());
}
}
public void setMyRingtone()
{
File k = new File("/sdcard/canon.mp3"); // 设置歌曲路径
ContentValues values = new ContentValues();
values.put(MediaStore.MediaColumns.DATA, k.getAbsolutePath());
values.put(MediaStore.MediaColumns.TITLE, k.getName());
values.put(MediaStore.MediaColumns.SIZE, 8474325);
values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3");
values.put(MediaStore.Audio.Media.ARTIST, "Madonna");
values.put(MediaStore.Audio.Media.DURATION, 230);
values.put(MediaStore.Audio.Media.IS_RINGTONE, true);

view plaincopy to clipboardprint?
<uses-permission android:name="android.permission.WRITE_SETTINGS"></uses-permission>
<uses-permission android:name="android.permission.WRITE_SETTINGS"></uses-permission>
程序运行就能将包中的canon.mp3拷贝到sdcard并且设置为默认铃声了
当然，你也可以拷贝这个文件到自己的私有目录data/data/zy.ring/路径下也可以
最后我们打开手机的设置铃声界面，可以看到我们的canon.mp3设置成了默认的铃声
