本文介绍了我怎样才能音频文件,用户挑选的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我希望得到一个句柄,我挑实际的音频文件。对于选择音频文件,我有一个看起来像这样的意图:

 意图audioIntent =新意图(Intent.ACTION_PICK,android.provider.MediaStore.Audio.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(audioIntent,0);

它让我得到一个弹出来接音频文件从,但我怎样才能得到我选择的文件?

在图像的情况下,我有:

  =位android.provider.MediaStore.Images.Media.getBitmap(getContentResolver(),intent.getData());

是否有音频文件相似的地方?


解决方案

 意图galleryIntent =新意图(Intent.ACTION_PICK,android.provider.MediaStore.Audio.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(galleryIntent,AUDIO_GALLERY_REQUEST_ code);如果(要求code == AUDIO_GALLERY_REQUEST_ code){
    如果(结果code == Activity.RESULT_OK){
        尝试{
          字符串路径= _getRealPathFromURI(背景下,intent.getData());
          文件中的音频=新的文件(路径);
        }赶上(例外五){
            e.printStackTrace();
        }
    }
}私人字符串_getRealPathFromURI(上下文的背景下,乌里contentUri){
    的String [] = PROJ {MediaStore.Audio.Media.DATA};
    CursorLoader装载机=新CursorLoader(背景下,contentUri,凸出,NULL,NULL,NULL);
    光标光标= loader.loadInBackground();
    INT与Column_Index = cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DATA);
    cursor.moveToFirst();
    返回cursor.getString(Column_Index中);
}

I would want to get a handle to the actual audio file that i pick. For selecting the audio file, i have an intent that looks like this :

Intent audioIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Audio.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(audioIntent , 0);

It allows me to get a popup to pick audio files from but how can i get the file that i have picked ?

In the case of images, i have :

bitmap = android.provider.MediaStore.Images.Media.getBitmap(getContentResolver(), intent.getData());

Is there something similar for audio files ?

解决方案

Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Audio.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(galleryIntent, AUDIO_GALLERY_REQUEST_CODE);

if (requestCode == AUDIO_GALLERY_REQUEST_CODE) {
    if (resultCode == Activity.RESULT_OK) {
        try {
          String path = _getRealPathFromURI(context, intent.getData());
          File audio = new File(path);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

private String _getRealPathFromURI(Context context, Uri contentUri) {
    String[] proj = { MediaStore.Audio.Media.DATA };
    CursorLoader loader = new CursorLoader(context, contentUri, proj, null, null, null);
    Cursor cursor = loader.loadInBackground();
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
}
