3.重写WebChromeClient中的相关方法

//ForAndroid<3.0
publicvoidopenFileChooser(ValueCallbackvalueCallback){
uploadMessage=valueCallback;
openImageChooserActivity();
}

//ForAndroid>=3.0
publicvoidopenFileChooser(ValueCallbackvalueCallback,StringacceptType){
uploadMessage=valueCallback;
openImageChooserActivity();
}

//ForAndroid>=4.1
publicvoidopenFileChooser(ValueCallbackvalueCallback,StringacceptType,Stringcapture){
uploadMessage=valueCallback;
openImageChooserActivity();
}

//ForAndroid>=5.0
@Override
publicbooleanonShowFileChooser(WebViewwebView,ValueCallbackfilePathCallback,WebChromeClient.FileChooserParamsfileChooserParams){
uploadMessageAboveL=filePathCallback;
openImageChooserActivity();
returntrue;
}
