Android raw,assets目录源使文件格式使用

播放raw目录下的mp3文件：

MediaPlayer mediaPlayer1;mediaPlayer1 = MediaPlayer.create(this, R.raw.boot); //文件路径 /raw/boot.mp3mediaPlayer1.start();mediaPlayer1.stop();

读取assets目录下图片资源文件：

<ImageView        android:id="@+id/assets_image"        android:layout_width="150dp"        android:layout_height="150dp"        />

final static String imageFileName = "images/hope.jpg";  //定义文件在文件目录，assets/images/hope.jpgImageView imageView = (ImageView)findViewById(R.id.assets_image);imageView.setImageBitmap(getImageFormAssets(imageFileName));//通过Bitmap对向设置ImageView所显示内容。private Bitmap getImageFormAssets(String fileName){        Bitmap bitmap = null;        AssetManager am = getResources().getAssets();        try {            InputStream inputStream = am.open(fileName);            bitmap = BitmapFactory.decodeStream(inputStream);            inputStream.close();        } catch (IOException e) {            e.printStackTrace();        }am.close();        return bitmap;}
