我在android(java)中编写了一个方法，即用于将图像上传到服务器。我希望从 C# 代码中调用此方法。我不知道该怎么做，java代码如下？
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button buttonUpload = (Button) findViewById(R.id.buttonUpload);
buttonUpload.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("imageName", imageName );
request.addProperty("base64String", compressedImageString);
//request.addProperty("compressedImageBitmap", compressedImageBitmap);
SoapSerializationEnvelope envelope = new
SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
envelope.dotNet = true;
try {
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapObject result = (SoapObject)envelope.bodyIn;
if(result != null)
{
Toast.makeText(getApplicationContext(), result.getProperty(0).toString(), Toast.LENGTH_LONG).show();
}
else
{
Toast.makeText(getApplicationContext(), "No Response",Toast.LENGTH_LONG).show();
}
} catch (Exception e) {
e.printStackTrace();
}
}
});
buttonBrowse = (Button) findViewById(R.id.buttonBrowse);
buttonBrowse.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(position!= null){
showPopup(MainActivity.this, position);
}
}
@SuppressWarnings("deprecation")
private void showPopup(final Activity activity, Point position) {
int popupWidth = 120;
int popupHeight = 130;
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.popup);
LayoutInflater layoutInflater = (LayoutInflater) activity.getSystemService(LAYOUT_INFLATER_SERVICE);
popupView = layoutInflater.inflate(R.layout.activity_popup, linearLayout);
popupWindow = new PopupWindow(activity);
popupWindow.setContentView(popupView);
popupWindow.setWidth(popupWidth);
popupWindow.setHeight(popupHeight);
int offset_X = 85;
int offset_Y = 5;
popupWindow.setBackgroundDrawable(new BitmapDrawable());
popupWindow.showAtLocation(popupView, Gravity.NO_GRAVITY, position.x + offset_X, position.y + offset_Y);
}
});
}
@Override
public void onWindowFocusChanged(boolean hasFocus){
int[] location = new int[2];
buttonBrowse.getLocationOnScreen(location);
position = new Point();
position.x = location[0];
position.y = location[1];
}
public void buttonGallery_Click(View v){
Intent intent = new Intent(

我想从c#调用buttonBrowse上的方法
最佳答案
您不能直接从 C# 代码调用 java 代码。
您可以将 java 类包装为 COM
请参阅下面的链接
关于c# - 如何从c#代码中调用java中的方法？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/14809360/
