前言

之前有过这个需求，但是好久没写了 忘了 这次算是一个记录吧 也写给迷茫中的你

之前我记得ios是可以直接打开的 但是Android不行 也是找了很多资料 经过不懈的努力 终于终于终于。。。嗯 呦西

1.了解类型

image 图片类型

video 视频类型

*/* 包含以上俩种

2.上代码

private ValueCallback<Uri> mUploadMessage;
private ValueCallback<Uri[]> mUploadCallbackAboveL;
private final static int FILECHOOSER_RESULTCODE = 101;

在WebView展示页面 创建 

WebChromeClient 对象

private final WebChromeClient mWebViewClient = new WebChromeClient() {

    @Override
    public void openFileChooser(ValueCallback<Uri> valueCallback, String s, String s1) {
        //Log.d(TAG, "openFileChoose(ValueCallback<Uri> uploadMsg, String acceptType, String capture)");
        mUploadMessage = valueCallback;
        Intent i = new Intent(Intent.ACTION_GET_CONTENT);
        i.addCategory(Intent.CATEGORY_OPENABLE);
        //如果选择图片就image 视频就video
        i.setType("*/*");
        CustomerServiceWebViewActivity.this.startActivityForResult(Intent.createChooser(i, "File Browser"),
                FILECHOOSER_RESULTCODE);

    }
};

重写 openFileChooser方法 

接收结果

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == FILECHOOSER_RESULTCODE) {
        if (null == mUploadMessage && null == mUploadCallbackAboveL) return;
        Uri result = data == null || resultCode != RESULT_OK ? null : data.getData();
        if (mUploadCallbackAboveL != null) {
            onActivityResultAboveL(requestCode, resultCode, data);
        } else if (mUploadMessage != null) {
            mUploadMessage.onReceiveValue(result);
            mUploadMessage = null;
        }
    }
}

选择多张图片

private void onActivityResultAboveL(int requestCode, int resultCode, Intent data) {
    if (requestCode != FILECHOOSER_RESULTCODE
            || mUploadCallbackAboveL == null) {
        return;
    }
    Uri[] results = null;
    if (resultCode == Activity.RESULT_OK) {
        if (data == null) {
        } else {
            String dataString = data.getDataString();
            ClipData clipData = data.getClipData();
            if (clipData != null) {
                results = new Uri[clipData.getItemCount()];
                for (int i = 0; i < clipData.getItemCount(); i++) {
                    ClipData.Item item = clipData.getItemAt(i);
                    results[i] = item.getUri();
                    //Log.e(TAG, "onActivityResultAboveL: " + results[i].getPath());
                }
            }
            if (dataString != null)
                results = new Uri[]{Uri.parse(dataString)};
            //Log.e(TAG, "onActivityResultAboveL: " + results.length);
        }
    }
    mUploadCallbackAboveL.onReceiveValue(results);
    mUploadCallbackAboveL = null;
    return;
}

最后把WebChromeClient设置给WebView

mWebView.setWebChromeClient(mWebViewClient);

结束。
