Android webview上传图片（适配3.0,4.0,5.0,6.0）

最近有个h5页面上传图片的需求，适配起多版本来，真是麻烦呀

废话不多说，上代码

 private ValueCallback<Uri> mUploadMessage;
    /**
     * 适配5.0系统
     */
    private ValueCallback<Uri[]> mUploadMessage5;
    private final static int FILECHOOSER_RESULTCODE = 1;

private class WebViewChromeClient extends WebChromeClient {
public void openFileChooser(ValueCallback<Uri> uploadFile) {
            mUploadMessage = uploadFile;
            Intent i = new Intent(Intent.ACTION_GET_CONTENT);
            i.addCategory(Intent.CATEGORY_OPENABLE);
            i.setType("image/*");
            startActivityForResult(
                    Intent.createChooser(i, "File Chooser"),
                    FILECHOOSER_RESULTCODE);
        }

        public void openFileChooser(ValueCallback<Uri> uploadFile,
                                    String acceptType) {
            openFileChooser(uploadFile);
        }

        public void openFileChooser(ValueCallback<Uri> uploadFile,
                                    String acceptType, String capture) {
            openFileChooser(uploadFile);
        }

        //适配5.0系统
        @TargetApi(Build.VERSION_CODES.LOLLIPOP)
        public boolean onShowFileChooser(WebView webView, ValueCallback<Uri[]> filePathCallback, FileChooserParams fileChooserParams) {

            mUploadMessage5 = filePathCallback;
            Intent i = new Intent(Intent.ACTION_GET_CONTENT);
            i.addCategory(Intent.CATEGORY_OPENABLE);
            i.setType("image/*");
            startActivityForResult(Intent.createChooser(i, "File Chooser"), FILECHOOSER_RESULTCODE);
            return true;
        }

    }

然后再给webview设置上这个 webView.setWebChromeClient(new WebViewChromeClient());

继续

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        Log.e("xingyun", "request" + requestCode +" result" + resultCode);

        if (requestCode == FILECHOOSER_RESULTCODE) {


            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){
                if (null == mUploadMessage5)
                    return;

                if (resultCode == RESULT_CANCELED) {
                    if (mUploadMessage5 != null) {
                        mUploadMessage5.onReceiveValue(null);
                        mUploadMessage5 = null;
                        return;
                    }
                }

            }else {
                if (null == mUploadMessage)
                    return;

                if (resultCode == RESULT_CANCELED) {
                    if (mUploadMessage != null) {
                        mUploadMessage.onReceiveValue(null);
                        mUploadMessage = null;
                        return;
                    }
                }
            }

            if (data==null)
                return;


            Uri result = data == null || resultCode != RESULT_OK ? null : data
                    .getData();

            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                mUploadMessage5.onReceiveValue(new Uri[]{result});
            } else {
                mUploadMessage.onReceiveValue(result);
            }
//            mUploadMessage.onReceiveValue(result);
//            mUploadMessage = null;


        }
    }

完、
