由于业务需要,APP内嵌H5,需要调去系统相册和拍照,网上找了点资料,整理一下,供大家参考:
private static final int REQUEST_CAMERA =1;
private static final int REQUEST_CHOOSE =2;
private ValueCallbackmUploadMessage;
private ValueCallbackmUploadMessagesAboveL;
private UricameraUri;
//5.0以后的方法
webView.setWebChromeClient(new WebChromeClient() {
@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
@Override
public boolean onShowFileChooser(WebView webView, ValueCallback filePathCallback, FileChooserParams fileChooserParams) {
if (mUploadMessagesAboveL !=null) {
mUploadMessagesAboveL.onReceiveValue(null);
mUploadMessagesAboveL =null;
}else {
mUploadMessagesAboveL = filePathCallback;
selectImage();
}
return true;
}
});
//选择图片和拍照,对应的string文件,可以自己写死:拍照,相册,取消
private void selectImage() {
ActionSheet.createBuilder(this, getSupportFragmentManager()).
setOtherButtonTitles(new String[]{getResources().getString(R.string.common_tip_photos), getResources().getString(R.string.common_picture)}).
setCancelButtonTitle(getResources().getString(R.string.common_cancel)).setCancelableOnTouchOutside(true).setListener(new ActionSheet.ActionSheetListener() {
public void onDismiss(ActionSheet actionSheet, boolean isCancel) {
if (mUploadMessage !=null) {
mUploadMessage.onReceiveValue(null);
mUploadMessage =null;
}
if (mUploadMessagesAboveL !=null) {
mUploadMessagesAboveL.onReceiveValue(null);
mUploadMessagesAboveL =null;
}
actionSheet.dismiss();
}
@RequiresApi(api = Build.VERSION_CODES.M)
public void onOtherButtonClick(ActionSheet actionSheet, int index) {
switch (index) {
case 0:

//拍照,添加权限申请 这个可以自己写下,我这边是项目中写好的,直接拿过来用了

基本都可以拿去用了,希望有帮助
