android获取音频绝对地址

定义如下控件和变量

    private Button btn_pickRecord;
    private TextView tv_path;

    final public static int FILE_SELECT_CODE = 1;
    String audioPath;

代码

public void pickRecord() {
        Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
        intent.setType("audio/*"); //选择音频
        intent.addCategory(Intent.CATEGORY_OPENABLE);

        try {
            startActivityForResult(Intent.createChooser(intent, "Select a File to Upload"), FILE_SELECT_CODE);
        } catch (android.content.ActivityNotFoundException ex) {
            Toast.makeText(this, "Please install a File Manager.", Toast.LENGTH_SHORT).show();
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        switch (requestCode) {
            case FILE_SELECT_CODE:
                if (resultCode == RESULT_OK) {
                    Uri uri = data.getData();
                    Log.e("uri", uri.toString());
                    String[] proj = {MediaStore.Images.Media.DATA };
                    Cursor cursor = getContentResolver().query(uri, proj, null, null, null);
                    int actual_image_column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
                    cursor.moveToFirst();
                    audioPath = cursor.getString(actual_image_column_index);
                    Log.e("uri", audioPath);
                    tv_path.setText(audioPath);
                }
                break;
            default:
                break;
        }
        super.onActivityResult(requestCode, resultCode, data);
    }
