Android 使用者圓形影象的設定與上傳
阿新 • • 發佈：2018-12-15
繼承了BaseActivity，就省略。。。。</pre>使用者圓形影象的設定與上傳，技術使用了框架imageloader jar包，可以進行圖片的載入，可以使用imageloader 也可以自己寫 圖片的選擇當時選擇了系統自帶的圖片管理器，圖片的剪下使用系統自帶的。直接貼出程式碼</p><p>1.<img src="https://img-blog.csdn.net/20161102143159959?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="" /><img src="https://img-blog.csdn.net/20161102143307944?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="" /><img src="https://img-blog.csdn.net/20161102143415764?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="" /><img src="https://img-blog.csdn.net/20161102143532109?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="" /></p><p></p><p><pre name="code" class="java">public class SettingUserImageActivity extends BaseActivity implements View.OnClickListener { private static final int ALBUM_REQUEST_CODE = 1;

接下來就是圓形圖片的回現了。。。和初始化網路載入圓形影象
private String path="/storage/emulated/0/chaoyang/"; if (fileIsExists(path + MyApplication.username + ".png")) { Bitmap bitmap = getLoacalBitmap(path + MyApplication.username + ".png"); iv_user_image.setImageBitmap(toRoundCorner(bitmap, 2)); } else { ImageLoader.getInstance().displayImage(MyApplication.getInstance().HostName + "/upload/selficon/" + MyApplication.username + ".png", iv_user_image, getImageOptions(new RoundedBitmapDisplayer(5))); } //判斷檔案是否存在 public boolean fileIsExists(String strFile) { try { File f = new File(strFile); if (!f.exists()) { return false; } } catch (Exception e) { return false; } return true; } /** * 圓形 * @param bitmap * @param ratio * @return */ public static Bitmap toRoundCorner(Bitmap bitmap, float ratio) { Bitmap output = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Bitmap.Config.ARGB_8888); Canvas canvas = new Canvas(output); final Paint paint = new Paint(); final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight()); final RectF rectF = new RectF(rect); paint.setAntiAlias(true); canvas.drawARGB(0, 0, 0, 0); canvas.drawRoundRect(rectF, bitmap.getWidth() / ratio, bitmap.getHeight() / ratio, paint); paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN)); canvas.drawBitmap(bitmap, rect, rect, paint); System.out.println("pixels+++++++" + String.valueOf(ratio)); return output; }
有時間寫一個demo，還有EventBus事件的傳遞處理，第一次寫部落格，諒解。
