适配Android WebView支持上传图片，视频

共计 22852 个字符，预计需要花费 58 分钟才能阅读完成。

问题原因：
H5 访问本地文件的时候，使用的 <input type=”file”> ,WebView 出于安全性的考虑，是限制了以上操作。
解决办法：
重写 WebviewChromeClient 中的 openFileChooser() 和 onShowFileChooser() 方法响应 <input type=”file”>，然后使用原生代码来实现调用本地相册和拍照的功能，最后在 onActiivtyResult 把选择的图片 URI 回传给 WebviewChromeClient。
注意：

Android4.1 系统，使用 openFileChooser(), 该方法在 Android5.0 已经被废弃。
Android5.0 以上类型，使用 onShowFileChooser()

一，初始化操作
ButtomDialogView mSelectImgDialog;
public static final int INPUT_FILE_REQUEST_CODE1;
public static final int INPUT_VIDEO_CODE = 2;
private static final int REQUEST_CODE_ALBUM = 3;
private ValueCallback<Uri[]> mFilePathCallback;
private ValueCallback<Uri> nFilePathCallback;
private String mCameraPhotoPath;
private Uri photoURI;

二，重写 WebChromeClient
mWebView.setWebChromeClient(new WebChromeClient() {
@Override
public void onProgressChanged(WebView view, int newProgress) {
super.onProgressChanged(view, newProgress);
}

@Override
public void onReceivedTitle(WebView view, String title) {
super.onReceivedTitle(view, title);
}

//for Android 4.0+
public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType, String capture) {
Log.d(“nimei”, “openFileChooser” + “—-> acceptType：” + acceptType);
if (nFilePathCallback != null) {
nFilePathCallback.onReceiveValue(null);
}
nFilePathCallback = uploadMsg;
if (“image/*”.equals(acceptType)) {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
takePictureIntent.putExtra(“android.intent.extras.CAMERA_FACING”, 0); // 调用后置摄像头
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
File photoFile = null;
try {
photoFile = createImageFile();
takePictureIntent.putExtra(“PhotoPath”, mCameraPhotoPath);
} catch (IOException ex) {
Log.e(“TAG”, “Unable to create Image File”, ex);
}
if (photoFile != null) {

}
startActivityForResult(takePictureIntent, INPUT_FILE_REQUEST_CODE);
