文件选择对话框中的Android的WebView不开放,如果"显示:无" [英] File chooser dialog not opening in android webview if "display:none"
问题描述
早上好开发商
好吧,我取得了一个Android的WebView应用程序,我米面临的一个小问题,我搜索了很多,但也没有发现任何有效的解决方案。
Well I have made an android webview application, I m facing a little issue, I searched alot but couldn't found any valid solution.
确定。问题是,。我有一个PHP / HTML code这样的
Ok. the problem is that. I have a php/Html code like this
<input type="file" name="banner_image" style="display:none;" id="banner_image" onChange="fileSelected('banner');" accept="image/*" />
的注意:的的风格=显示:无;
我打电话是输入字段的的 DIV
的onClick通过jQuery这样的onclick事件
I m calling the onclick event of input field from onClick of a div
via Jquery like this
<div class="profile-pic-txt" onClick="openFileDialog('profile');"> Click here to add
Profile Picture
<p>200px/200px</p>
</div>
和这里是我的Java脚本打开文件对话框()函数
and here is my java-script openFileDialog() function
function openFileDialog(test)
{
$("#banner_image").click();
console.log("Test");
}
它不是我打开文件选择对话框。
Its not opening my file chooser dialog.
但是,当我删除此显示:无;从我上面的$ C $
ç它只是工作的罚款。我的iPhone在这两个条件,但在Android的WebView中测试了这个它的做工精细它不是我的调用文件选择对话框中,同时保持显示:无
。
But when i remove this display:none;
from my above code its just working fine. I tested this in iPhone its working fine in both conditions but in android webview its not invoking my file chooser dialog while keeping display:none
.
问
我必须让我的浏览按钮,从我的网页作为模板/设计要求不可见的(我已经有显示完成:无
)
和过去这里是我的Android的WebView配置code。
and in the last here is my android webview configuration code.
private void configureWebview() {
webView.getSettings().setDefaultZoom(ZoomDensity.FAR);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setCacheMode(MODE_APPEND);
webView.getSettings().setUseWideViewPort(true);
webView.getSettings().setRenderPriority(RenderPriority.HIGH);
webView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
webView.setWebViewClient(new MyWebViewClient());
webView.setWebChromeClient(new WebChromeClient() {
@Override
public boolean onConsoleMessage(ConsoleMessage cm) {
Log.e("Console Webview",
cm.message() + " -- From line " + cm.lineNumber()
+ " of " + cm.sourceId());
return true;
}

i.setType("image/*");
MainActivity.this.startActivityForResult(
Intent.createChooser(i, "File Chooser"),
MainActivity.FILECHOOSER_RESULTCODE);
}
});
}
只是在重复我的问题:无在&LT;输入名称=banner_image的风格=显示:同时保持
显示文件选择器不开放:没有; ID =banner_image的onChange =fileSelected('旗帜');类型=文件接受=图像/ */&GT;
推荐答案
如果您使用的输入文件不起作用显示:无
input file doesn't work if you use display:none
只是把它的可视区域之外,例如使用的位置是:绝对的;左:-500px;
just put it outside the viewable area, for example with position: absolute;left: -500px;
