今天有點累，我就直接把代碼粘上了，不過我在裡面加了注釋，方便大家理解。

Layout:
RoundImageView讓圖片變圓的工具類(直接復制即可):

Bitmap.Config.ARGB_8888 : Bitmap.Config.RGB_565); Canvas canvas1 = new Canvas(b); // canvas.setBitmap(bitmap); drawable.setBounds(0, 0, getWidth(), getHeight()); drawable.draw(canvas1); } if (null == b) { return; } Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true); int w = getWidth(), h = getHeight(); Bitmap roundBitmap = getCroppedBitmap(bitmap, w); canvas.drawBitmap(roundBitmap, 0, 0, null); } public static Bitmap getCroppedBitmap(Bitmap bmp, int radius) { Bitmap sbmp; if (bmp.getWidth() != radius || bmp.getHeight() != radius) sbmp = Bitmap.createScaledBitmap(bmp, radius, radius, false); else sbmp = bmp; Bitmap output = Bitmap.createBitmap(sbmp.getWidth(), sbmp.getHeight(), Bitmap.Config.ARGB_8888); Canvas canvas = new Canvas(output); final int color = 0xffa19774; final Paint paint = new Paint(); final Rect rect = new Rect(0, 0, sbmp.getWidth(), sbmp.getHeight()); paint.setAntiAlias(true); paint.setFilterBitmap(true); paint.setDither(true); canvas.drawARGB(0, 0, 0, 0); paint.setColor(Color.parseColor("#BAB399")); canvas.drawCircle(sbmp.getWidth() / 2 + 0.7f, sbmp.getHeight() / 2 + 0.7f, sbmp.getWidth() / 2 + 0.1f, paint); paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN)); canvas.drawBitmap(sbmp, rect, rect, paint); return output; } }
FileUitlity給相機拍照的照片設置存放文件夾的工具類(可直接復制)
public class FileUitlity { public final static String USER_HAED="head"; private static String ROOT_CACHE; public static String ROOT_DIR="yt_xyt"; private static FileUitlity instance = null; private FileUitlity() { } public static FileUitlity getInstance(Context context) { if (instance == null) { if (Environment.getExternalStorageState().equals( Environment.MEDIA_MOUNTED)) { ROOT_CACHE = (Environment.getExternalStorageDirectory() + "/" + ROOT_DIR + "/"); } else { ROOT_CACHE = (context.getFilesDir().getAbsolutePath() + "/"+ROOT_DIR+"/"); } File dir = new File(ROOT_CACHE); if (!dir.exists()) { dir.mkdirs(); } instance = new FileUitlity(); } return instance; } public File makeDir(String dir) { File fileDir = new File(ROOT_CACHE + dir); if (fileDir.exists()) { return fileDir; } else { fileDir.mkdirs(); return fileDir; } } }
