圖片上傳
效果圖展示
圖片上傳前的準備
帶圓角的方形圖片
使用的第三方控制元件，主要關注如下一些檔案
- RoundedDrawable
- RoundedImageView
- RoundedTransformationBuilder
- res目錄下的anim、color以及values下的attrs
佈局檔案程式碼如下：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" 從下而上彈出的PopupWindow
關注如下檔案：
- CoverSelelctPopupWindow
- cover_select_pop_layout.xml
public class CoverSelelctPopupWindow extends PopupWindow {
private Button albumBtn, photoGraphBtn,cancelBtn;
private View mMenuView;
public CoverSelelctPopupWindow(Activity context, OnClickListener itemsOnClick) {
super(context);
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mMenuView = inflater.inflate(R.layout.cover_select_pop_layout, null);
albumBtn = (Button) mMenuView.findViewById(R.id.btn_album);
photoGraphBtn = (Button) mMenuView.findViewById(R.id.btn_photo_graph);
//startRecordBtn = (Button) mMenuView.findViewById(R.id.btn_upload_record);
cancelBtn = (Button) mMenuView.findViewById(R.id.btn_cancel_join);
// 設定按鈕監聽
albumBtn.setOnClickListener(itemsOnClick);
photoGraphBtn.setOnClickListener(itemsOnClick);
// 設定SelectPicPopupWindow的View
this.setContentView(mMenuView);
// 設定SelectPicPopupWindow彈出窗體的寬
this.setWidth(LayoutParams.FILL_PARENT);
// 設定SelectPicPopupWindow彈出窗體的高
this.setHeight(LayoutParams.WRAP_CONTENT);
// 設定SelectPicPopupWindow彈出窗體可點選
this.setFocusable(true);
// 設定SelectPicPopupWindow彈出窗體動畫效果
this.setAnimationStyle(R.style.AnimBottom);
// 例項化一個ColorDrawable顏色為半透明
ColorDrawable dw = new ColorDrawable(0x00FFFFFF);
// 設定SelectPicPopupWindow彈出窗體的背景
this.setBackgroundDrawable(dw);
// mMenuView新增OnTouchListener監聽判斷獲取觸屏位置如果在選擇框外面則銷燬彈出框
mMenuView.setOnTouchListener(new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
int height = mMenuView.findViewById(R.id.pop_layout).getTop();
int y = (int) event.getY();
if (event.getAction() == MotionEvent.ACTION_UP) {
if (y < height) {
dismiss();
}
}
return true;
}
});
cancelBtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
dismiss();
}
});
}

拍照獲取圖片失敗的問題
過程中發現，如果拍照獲取圖片的儲存路徑與裁切後儲存的路徑一致的話會出現問題，所以分別設定了兩個路徑，請參考
- FileUtil

拍照獲取圖片角度不正確的問題
case ACTIVITY_CAMERA_REQUESTCODE:
if (resultCode == Activity.RESULT_OK) {
BitmapFactory.Options bitmapOptions = new BitmapFactory.Options();
bitmapOptions.inSampleSize = 2;
int degree = FileUtil.readPictureDegree(FileUtil.getHeadPhotoDir() + FileUtil.HEADPHOTO_NAME_RAW);
Bitmap cameraBitmap = BitmapFactory.decodeFile(FileUtil.getHeadPhotoDir() + FileUtil.HEADPHOTO_NAME_RAW, bitmapOptions);
cameraBitmap = FileUtil.rotaingImageView(degree, cameraBitmap);
FileUtil.saveCutBitmapForCache(this,cameraBitmap);
CommonUtils.cutPhoto(this, Uri.fromFile(FileUtil.getHeadPhotoFileRaw()), true);
}
break;如果不存在圖片角度的問題可以直接呼叫(我測試的時候發現：型號相同，系統版本相同的手機上也有可能存在角度不統一的問題，如果有更好的處理方法，歡迎指教！)
CommonUtils.cutPhoto(this, Uri.fromFile(FileUtil.getHeadPhotoFileRaw()), true);上傳成功之後刪除臨時檔案
可以根據伺服器介面形式，來進行圖片上傳，我這邊上傳的格式是
傳入兩個引數
- uid 使用者id
- image 圖片二進位制資料
case ACTIVITY_MODIFY_PHOTO_REQUESTCODE:
String coverPath = FileUtil.getHeadPhotoDir() + FileUtil.HEADPHOTO_NAME_TEMP;
Bitmap bitmap = BitmapFactory.decodeFile(coverPath);
imgCover.setImageBitmap(bitmap);
//接下來是完成上傳功能
/* HttpUtil.uploadCover(this, UrlContainer.UP_LIVE_COVER + "?uid="
+ LoginUtils.getInstance(this), coverPath, this);*/
//成功之後刪除臨時圖片
FileUtil.deleteTempAndRaw();圖片上傳以及上傳之後的處理
大家可以在自己的網路請求中按照如下方式處理，然後根據上傳成功和失敗的回撥做相應的事情
ublic static void uploadCover(final Context context, final String url, final String path,
final UploadLiveCoverListener listener) {
ThreadPoolUtils.execute(new Runnable() {
@Override
public void run() {
// 新增金鑰
try {
HttpClient client = new DefaultHttpClient();
MultipartEntity multipartContent = getEntity(context,
new HashMap<String, String>());
FileBody fileBody = new FileBody(new File(path), "image/jpeg", "UTF-8");
multipartContent.addPart("image", fileBody);
String ret = doPost(context, url, multipartContent, client);
JSONObject json = new JSONObject(ret);
int status = json.getInt("status");
if (status == 0) {
JSONObject resultO = json.getJSONObject("result");
String imgUrl = resultO.getString("img_url");
listener.onUploadSuccess(imgUrl);
}else {
listener.onUploadFail(status);
}
deleteTempAndRaw(path);
} catch (Exception e) {
listener.onUploadFail(-1);
}
}
});
}
