android中Bitmap對象怎麼儲存為檔案?

Bitmap類有一compress成員,可以把bitmap儲存到一個stream中。

例如:

public void saveMyBitmap(String bitName) throws IOException {
    File f = new File("/sdcard/Note/" + bitName + ".png");
    f.createNewFile();
    FileOutputStream fOut = null;
    try {
            fOut = new FileOutputStream(f);
    } catch (FileNotFoundException e) {
            e.printStackTrace();
    }
    mBitmap.compress(Bitmap.CompressFormat.PNG, 100, fOut);
    try {
            fOut.flush();
    } catch (IOException e) {
            e.printStackTrace();
    }
    try {
            fOut.close();
    } catch (IOException e) {
            e.printStackTrace();
    }
}
