Question

Let’s say I have some strings in Java that I’ve retrieved from a web script. It doesn’t matter really, they’re just strings stored in variables.

Now my question is how to dynamically append them to the application (to show the user) and possibly style their position, from Java.

To draw an analogy, I want to do something similar to the following in JavaScript:

var text = document.createElement('div'); 
text.appendChild(document.createTextNode("some string")); 
text.style.position = "whatever";
// etc, more styling
theDiv.appendChild(text); // add this new thing of text I created to the main application for the users to see

I’ve looked into the TextView, and I don’t seem to be using it properly (I don’t understand the constructor I guess?). What I want to try right now is to have the user press a button in my application and then have some text dynamically generated. Here’s what I’ve been trying:

search_button = (Button) findViewById (R.id.backSearchButton);
        search_button.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {


            String test = new String("testing!"); 

            TextView test2 = new TextView(this);    //constructor is wrong, this line gives me an error

            test2.setText(test); 

            setContentView(test2); 

        }
    });

As you can probably tell, I don’t come from much of a Java background. I’m just trying to draw parallels to stuff I would want to do for a web app.

Thanks for the help.

Try:

TextView test2 = new TextView(ParentActivity.this);

replace “ParentActivity” with the name of your activity.
