回答2：Github上有個Os-FileUp項目提供了一些方法.
webView.setWebChromeClient(new WebChromeClient(){ //For Android 3.0+ public void openFileChooser(ValueCallback<Uri> uploadMsg){mUM = uploadMsg;Intent i = new Intent(Intent.ACTION_GET_CONTENT);i.addCategory(Intent.CATEGORY_OPENABLE);i.setType('image/*');MainActivity.this.startActivityForResult(Intent.createChooser(i,'File Chooser'), FCR); } // For Android 3.0+, above method not supported in some android 3+ versions, in such case we use this public void openFileChooser(ValueCallback uploadMsg, String acceptType){mUM = uploadMsg;Intent i = new Intent(Intent.ACTION_GET_CONTENT);i.addCategory(Intent.CATEGORY_OPENABLE);i.setType('*/*');MainActivity.this.startActivityForResult(Intent.createChooser(i, 'File Browser'),FCR); } //For Android 4.1+ public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType, String capture){mUM = uploadMsg;Intent i = new Intent(Intent.ACTION_GET_CONTENT);i.addCategory(Intent.CATEGORY_OPENABLE);i.setType('image/*');MainActivity.this.startActivityForResult(Intent.createChooser(i, 'File Chooser'), MainActivity.FCR); } //For Android 5.0+ public boolean onShowFileChooser( WebView webView, ValueCallback<Uri[]> filePathCallback, WebChromeClient.FileChooserParams fileChooserParams){if(mUMA != null){ mUMA.onReceiveValue(null);}mUMA = filePathCallback;Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);if(takePictureIntent.resolveActivity(MainActivity.this.getPackageManager()) != null){ File photoFile = null; try{photoFile = createImageFile();takePictureIntent.putExtra('PhotoPath', mCM); }catch(IOException ex){Log.e(TAG, 'Image file creation failed', ex); } if(photoFile != null){mCM = 'file:' + photoFile.getAbsolutePath();takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile)); }else{takePictureIntent = null; }}Intent contentSelectionIntent = new Intent(Intent.ACTION_GET_CONTENT);contentSelectionIntent.addCategory(Intent.CATEGORY_OPENABLE);contentSelectionIntent.setType('image/*');Intent[] intentArray;if(takePictureIntent != null){ intentArray = new Intent[]{takePictureIntent};}else{ intentArray = new Intent[0];}Intent chooserIntent = new Intent(Intent.ACTION_CHOOSER);chooserIntent.putExtra(Intent.EXTRA_INTENT, contentSelectionIntent);chooserIntent.putExtra(Intent.EXTRA_TITLE, 'Image Chooser');chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentArray);startActivityForResult(chooserIntent, FCR);return true; }});}
