1. H5 可以直接拍照 通过 WebChromeClient 来处理
// 辅助处理JavaScript、页喧解析渲染、页面标题、加载进度等等
mWebView.setWebChromeClient(commonWebChromeClient);
2. 重写 WebChromeClient 方法 onShowFileChooser 5.0 及以上和openFileChooser 4-5.0
获取参数 这两对象接收拍照完后的流
public ValueCallback<Uri> mUploadMessage; 5.0以下
public ValueCallback<Uri[]> uploadMessage; 5.0 及其以上
3. 拍照调用
Intent takeIntent = new Intent (MediaStore.ACTION_IMAGE_CAPTURE);
//下面这句指定调用相机拍照后的照片存储的路径
takeIntent.putExtra (MediaStore.EXTRA_OUTPUT, Uri.fromFile (new File (mTempPhotoPath)));
startActivityForResult (takeIntent, REQUEST_SELECT_FILE);
4.拍照结果回调
拍照回传后的intent 数据为空
需要对 path 进行处理
5.0 及其以上
uploadMessage.onReceiveValue (new Uri[]{Uri.fromFile (new File (mTempPhotoPath))});
uploadMessage = null;
5.0以下：
Uri result = intent == null || resultCode != RESULT_OK ? null : intent.getData ();
if (result == null) {
//多操作了一步
Uri[] ll = new Uri[]{Uri.fromFile (new File (mTempPhotoPath))};
if (ll != null && ll.length > 0) {
result = ll[0];
}
}
mUploadMessage.onReceiveValue (result);
mUploadMessage = null;
5.0及以下 获取Uri 的方法是否只有这一种？？
File file = new File(PictureUtil.bitmapToPath(sourcePath));
Uri uri = Uri.fromFile(file);
其他方法：
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("image/*");
startActivityForResult(Intent.createChooser(i,"Image Chooser"),FILE_CHOOSER_RESULT_CODE);
文件：Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("image/");
startActivityForResult(Intent.createChooser(i, "File Browser"), RESULTCODE);
？？
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("image/");
startActivityForResult(Intent.createChooser(i, "Image Chooser"), FILE_CHOOSER_RESULT_CODE);
相册 ：Intent pickIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(pickIntent, CODE);
9 Intent.ACTION_CHOOSER
String: android.intent.action.CHOOSER显示一个activity选择器，允许用户在进程之前选择他们想要的,与之对应的是Intent.ACTION_GET_CONTENT.
10. Intent.ACTION_GET_CONTENT
String: android.intent.action.GET_CONTENT允许用户选择特殊种类的数据，并返回（特殊种类的数据：照一张相片或录一段音）
Input: TypeOutput:URI
int requestCode = 1001;
Intent intent = new Intent(Intent.ACTION_GET_CONTENT); // "android.intent.action.GET_CONTENT"
intent.setType("image/*"); // 查看类型，如果是其他类型，比如视频则替换成 video/*，或 */*
Intent wrapperIntent = Intent.createChooser(intent, null);
startActivityForResult(wrapperIntent, requestCode);
//拍照 REQUEST_CODE_TAKE_PICTURE 为返回的标识
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); //"android.media.action.IMAGE_CAPTURE";
intent.putExtra(MediaStore.EXTRA_OUTPUT, Mms.ScrapSpace.CONTENT_URI); // output,Uri.parse("content:/s/scrapSpace");
startActivityForResult(intent, REQUEST_CODE_TAKE_PICTURE);
//添加音视频
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType(contentType); //String VIDEO_UNSPECIFIED = "video/*";
Intent wrapperIntent = Intent.createChooser(intent, null);
((Activity) context).startActivityForResult(wrapperIntent, requestCode);
//拍摄视频
int durationLimit = getVideoCaptureDurationLimit(); //SystemProperties.getInt("ro.media.enc.lprof.duration", 60);
Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 0);
intent.putExtra(MediaStore.EXTRA_SIZE_LIMIT, sizeLimit);
intent.putExtra(MediaStore.EXTRA_DURATION_LIMIT, durationLimit);
startActivityForResult(intent, REQUEST_CODE_TAKE_VIDEO);
//录音
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType(ContentType.AUDIO_AMR); //String AUDIO_AMR = "audior";
intent.setClassName("com.android.soundrecorder",
"com.android.soundrecorder.SoundRecorder");
((Activity) context).startActivityForResult(intent, requestCode);
