我实现了webchromeclient的openFileChooser,它打开了一个PHP页面。当我从图库中选择图像时,它会再次打开图库,即图库正在打开两次。
不知道如何摆脱这种情况。
这是我的代码:
public class MyWebChromeClient extends WebChromeClient{
public void openFileChooser(ValueCallback<Uri> uploadMsg) {
mUploadMessage = uploadMsg;
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> uploadMsg, String acceptType ) {
mUploadMessage = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("*/*");
startActivityForResult(
Intent.createChooser(i, "File Browser"),
FILECHOOSER_RESULTCODE);
}
}
这是onactivityresult:
protected void onActivityResult(int requestCode, int resultCode,
Intent intent) {
if (requestCode == FILECHOOSER_RESULTCODE) {
if (null == mUploadMessage)
return;
Uri result = intent == null || resultCode != RESULT_OK ? null
: intent.getData();
mUploadMessage.onReceiveValue(result);
mUploadMessage = null;
}
}

如果您将活动声明为
,请检查清单文件单个实例
然后将在错误的时间调用Activity on result方法。
