我正在开发一个应用程序：我正在尝试将音频文件设置为铃声 我看到很多帖子，但没有人真正帮助过我，所以我决定问这个问题。
单击按钮时使用此代码：
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.setType("audio/*");
startActivityForResult(Intent.createChooser(intent, "Choose Sound File"), Audio);
}
in onActivityResult我正在尝试获取文件路径，然后使用以下代码将音频文件设置为铃声：
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == Audio && requestCode==RESULT_OK) {
Uri s1 = data.getData();
String s = s1.getPath();
if(s!=null){
try {
k = new File(new URI(s)); //(File k;)
} catch (URISyntaxException e) {
e.printStackTrace();
}
ContentValues values = new ContentValues();
values.put(MediaStore.MediaColumns.DATA, k.getAbsolutePath());
values.put(MediaStore.MediaColumns.TITLE, "My Song title");
values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mpeg");
values.put(MediaStore.Audio.Media.ARTIST, "Some Artist");
values.put(MediaStore.Audio.Media.IS_RINGTONE, false);
values.put(MediaStore.Audio.Media.IS_NOTIFICATION, true);
values.put(MediaStore.Audio.Media.IS_ALARM, false);
values.put(MediaStore.Audio.Media.IS_MUSIC, false);
//Insert it into the database
Uri uri = MediaStore.Audio.Media.getContentUriForPath(k.getAbsolutePath());
Uri newUri = getContentResolver().insert(uri, values);
RingtoneManager.setActualDefaultRingtoneUri(
MainActivity.this,
RingtoneManager.TYPE_RINGTONE,
newUri);
}
}
}
不幸的是这段代码不起作用 我很感激你的回答。抱歉我的英语不好。

我看到很多帖子，但是任何人都展示了我应该做的事情。所以我决定创建这个完整的答案，我可以解决我的问题......
这是我使用的MainActivity.java
import java.io.File;
import android.app.Activity;
import android.content.ContentValues;
import android.content.Intent;
import android.media.RingtoneManager;
import android.net.Uri;
import android.os.Bundle;
import android.provider.MediaStore;
import android.view.View;
import android.widget.Button;
public class MainActivity extends Activity {
Button b;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
b = (Button) findViewById(R.id.button2);
b.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
Intent intent1 = new Intent();
intent1.setAction(Intent.ACTION_GET_CONTENT);
intent1.setType("audio/*");
startActivityForResult(
Intent.createChooser(intent1, "Choose Sound File"), 6);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK && requestCode == 6) {
Uri i = data.getData(); // getData
String s = i.getPath(); // getPath
File k = new File(s); // set File from path
if (s != null) { // file.exists
ContentValues values = new ContentValues();
values.put(MediaStore.MediaColumns.DATA, k.getAbsolutePath());
values.put(MediaStore.MediaColumns.TITLE, "ring");
values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3");
values.put(MediaStore.MediaColumns.SIZE, k.length());
values.put(MediaStore.Audio.Media.ARTIST, R.string.app_name);
values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
values.put(MediaStore.Audio.Media.IS_NOTIFICATION, true);
values.put(MediaStore.Audio.Media.IS_ALARM, true);
values.put(MediaStore.Audio.Media.IS_MUSIC, false);
Uri uri = MediaStore.Audio.Media.getContentUriForPath(k
.getAbsolutePath());
getContentResolver().delete(
uri,
MediaStore.MediaColumns.DATA + "=\""
+ k.getAbsolutePath() + "\"", null);
Uri newUri = getContentResolver().insert(uri, values);
try {
RingtoneManager.setActualDefaultRingtoneUri(
MainActivity.this, RingtoneManager.TYPE_RINGTONE,
newUri);
} catch (Throwable t) {
}
}
}
}
}
最后，在AndroidManifest.xml中添加这些权限非常重要，例如，如果您没有添加写入外部存储的权限，您的应用就会像我的那样崩溃.. xD
您需要什么：
<uses-permission android:name="android.permission.WRITE_SETTINGS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.CHANGE_CONFIGURATION" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
您可以在Google Play上试用我的应用：BackAtel Audio Manager
希望有所帮助....我的问题现在已经解决了!!我希望我也解决了你的问题：））

答案 2 :(得分：0)
将音频设置为铃声与警报中的设置音相同，代码为：
ContentValues values = new ContentValues(4);
long current = System.currentTimeMillis();
values.put(MediaStore.MediaColumns.DATA, path+audioname );
values.put(MediaStore.MediaColumns.TITLE, path+audioname );
values.put(MediaStore.Audio.Media.DATE_ADDED, (int) (current / 1000));
values.put(MediaStore.Audio.Media.MIME_TYPE, "audio/3gpp");
//new
values.put(MediaStore.Audio.Media.ARTIST, "cssounds ");
values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
values.put(MediaStore.Audio.Media.IS_NOTIFICATION, false);
values.put(MediaStore.Audio.Media.IS_ALARM, true);
values.put(MediaStore.Audio.Media.IS_MUSIC, false);
///new
// values.put(MediaStore.Audio.Media.DATA, audiofile.getAbsolutePath());
// ContentResolver contentResolver = getContentResolver();
//Insert it into the database
this.getContentResolver().insert(MediaStore.Audio.Media.getContentUriForPath(path+audioname), values);
//RingtoneManager.setActualDefaultRingtoneUri(Activity.this,
// RingtoneManager.TYPE_RINGTONE, newUri);
sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://"+path+audioname
+ Environment.getExternalStorageDirectory())));
// sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://"+path+editText1)));
//Toast.makeText(this, "New Alarm Sound " + editText1 +format, Toast.LENGTH_LONG).show();
}
使用此代码，它可以将您的声音放入特定的SD卡文件夹中，然后将其设置为铃声和闹铃：
values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
values.put(MediaStore.Audio.Media.IS_ALARM, true);
