Android Question how to deal (Context context) { this.context = context; }

hears · Apr 1, 2020

I am making a library now.
in java code function need "context context".
how to pass from b4a ?

B4X:

public void setCameraSurfaceHolder(Context context, SurfaceView surfaceView) {
        this.context = context;
        this.surfaceView = surfaceView;
        surfaceHolder = surfaceView.getHolder();
        surfaceHolder.addCallback(callback);
        surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
        callback.setContext(context);
    }

Context context = BA.applicationContext;
presumably you already have this at the top: import anywheresoftware.b4a.BA.*;

also in b4a in you prefer:

B4X:

Sub GetContext As JavaObject
   Return GetBA.GetField("context")
End Sub

Missing the GetBA method:

B4X:

Sub GetBA As JavaObject
  Dim jo As JavaObject
  Dim cls As String = Me
  cls = cls.SubString("class ".Length)
  jo.InitializeStatic(cls)
  Return jo.GetFieldJO("processBA")
End Sub

Correct way to get Context is with JavaObject.InitializeContext.
