Android 2.3.5系统内置图片Gallery程序无法正常调用
之前开发了一个图片功能，就是即可以拍照，又可以直接调用系统内置Gallery程序选择图片，然后将图片显示在自己的程序ImageView中。
该功能在华为T8620可以正常使用（Android4.0），但是最近试了另一款康佳的v926（Android 2.3.5），却无法从Gallery的图片选择界面中选中的图片显示在ImageView中（会一直让你选，没反应），测试代码发现竟然不肯回调函数 onActivityResult()! 所以只能到这来请教大牛们了，望指点~~
主要代码：
Java code?private void doPickPhotoAction() { Context context = PicPostActivity.this; // Wrap our context to inflate list items using correct theme final Context dialogContext = new ContextThemeWrapper(context, android.R.style.Theme_Light); String cancel="返回"; String[] choices; choices = new String[2]; choices[0] = getString(R.string.pick_photo); //从相册中选择 choices[1] = getString(R.string.take_photo); //拍照 ListAdapter adapter = new ArrayAdapter<String>(dialogContext, android.R.layout.simple_list_item_1, choices); AlertDialog.Builder builder = new AlertDialog.Builder(dialogContext); builder.setTitle(R.string.attach_picture_from); builder.setSingleChoiceItems(adapter, -1, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); switch (which) { case 0: HengtuoUtil.log(0, TAG, "选择相册选择"); doPickPhotoFromGallery();// 从相册中去获取 break; case 1:{ String status=Environment.getExternalStorageState(); if(status.equals(Environment.MEDIA_MOUNTED)){//判断是否有SD卡 PHOTO_DIR = new File(Constants.PHOTO_DIR_SDK); HengtuoUtil.log(0, TAG, "选择相机拍摄"); doTakePhoto();// 用户点击了从照相机获取 } else{ //PicPostActivity.showToast("没有SD卡"); //无SD卡则直接选择手机 PHOTO_DIR = new File(Constants.PHOTO_DIR_PHONE); HengtuoUtil.log(3, TAG, "没有SD卡"); } break; } } } }); builder.setNegativeButton(cancel, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); } }); AlertDialog dialog = builder.create(); dialog.show(); } /** * 拍照获取图片 */ protected void doTakePhoto() { try { // Launch camera to take photo for selected contact PHOTO_DIR.mkdirs();// 创建照片的存储目录 mCurrentPhotoFile = new File(PHOTO_DIR, getPhotoFileName());// 给新照的照片文件命名 final Intent intent = getTakePickIntent(mCurrentPhotoFile); startActivityForResult(intent, CAMERA_WITH_DATA); } catch (ActivityNotFoundException e) { Toast.makeText(this, "创建照片失败",Toast.LENGTH_LONG).show(); HengtuoUtil.log(3, TAG, "创建照片失败"); } } public static Intent getTakePickIntent(File f) { Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE, null); intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f)); HengtuoUtil.log(1, "hengtuo.PicPostActivity", "拍照成功"); return intent; } /** * 用当前时间给取得的图片命名 */ private String getPhotoFileName() { Date date = new Date(System.currentTimeMillis()); SimpleDateFormat dateFormat = new SimpleDateFormat( "'IMG'_yyyyMMdd_HHmmss"); return dateFormat.format(date) + ".jpg"; } /** * 请求Gallery程序 */ protected void doPickPhotoFromGallery() { try { // Launch picker to choose photo for selected contact final Intent intent = getPhotoPickIntent(); startActivityForResult(intent, PHOTO_CUT_WITH_DATA); } catch (ActivityNotFoundException e) { Toast.makeText(this, getString(R.string.photoPickerNotFoundText), Toast.LENGTH_LONG).show(); HengtuoUtil.log(3, TAG, getString(R.string.photoPickerNotFoundText)); } } /** * 封装请求Gallery的intent * @return */ public static Intent getPhotoPickIntent() { Intent intent = new Intent(Intent.ACTION_GET_CONTENT, null); intent.setType("image/*"); intent.putExtra("crop", "true"); intent.putExtra("aspectX", 1); intent.putExtra("aspectY", 1); intent.putExtra("outputX", 600); intent.putExtra("outputY", 400); intent.putExtra("return-data", true); return intent; } /** * 因为调用了Camera和Gally所以要判断他们各自的返回情况,他们启动时是这样的startActivityForResult */ protected void onActivityResult(int requestCode, int resultCode, Intent data) { if(resultCode == RESULT_CANCELED)//回到选择照片来源 { doPickPhotoAction(); return; } if (resultCode != RESULT_OK){ //回到主页 startActivity(new Intent(PicPostActivity.this,MainActivity.class)); finish(); return; } switch (requestCode) { case PHOTO_PICKED_WITH_DATA: {// 调用Gallery返回的 break; } case CAMERA_WITH_DATA: {// 照相机程序返回的,再次调用图片剪辑程序去修剪图片 doCropPhoto(mCurrentPhotoFile); break; } case PHOTO_CUT_WITH_DATA:{ if (data != null) { try { setPicToView(data); //裁剪图片 } catch (Exception e) { Toast.makeText(getApplicationContext(), "裁剪失败！", Toast.LENGTH_LONG).show(); HengtuoUtil.log(3, TAG+".onActivityResult", "裁剪失败！"); } } break; } } } private void setPicToView(Intent picdata) throws Exception { Bundle extras = picdata.getExtras(); if (extras != null) { Bitmap photo = extras.getParcelable("data"); picName = getPhotoFileName(); File f = new File(Constants.PHOTO_DIR_TEMP); if(!f.exists()) f.mkdirs(); mCurrentPhotoFile = new File(Constants.PHOTO_DIR_TEMP+"/"+ picName); mCurrentPhotoFile.createNewFile(); BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(mCurrentPhotoFile)); photo.compress(Bitmap.CompressFormat.JPEG, 100, bos); bos.flush(); bos.close(); HengtuoUtil.log(0, TAG, "图片保存成功"); ImageView imgView = (ImageView) findViewById(R.id.img_view);// 获取控件 imgView.setImageBitmap(photo);// 填充控件 } } protected void doCropPhoto(File f) { try { // 启动gallery去剪辑这个照片 final Intent intent = getCropImageIntent(Uri.fromFile(f)); startActivityForResult(intent, PHOTO_CUT_WITH_DATA); } catch (Exception e) { Toast.makeText(this, "没有找到照片", Toast.LENGTH_LONG).show(); HengtuoUtil.log(3, TAG, getString(R.string.photoPickerNotFoundText)); } } /** * Constructs an intent for image cropping. 调用图片剪辑程序 */ public static Intent getCropImageIntent(Uri photoUri) { Intent intent = new Intent("com.android.camera.action.CROP"); intent.setDataAndType(photoUri, "image/*"); intent.putExtra("crop", "true"); intent.putExtra("aspectX", 1); intent.putExtra("aspectY", 1); intent.putExtra("outputX", 600); intent.putExtra("outputY", 400); intent.putExtra("return-data", true); return intent; }
华为这山寨货！！！！！！！！！ 我也碰到同样问题了！！！
