如何在java中的URL中间添加用户输入？

Question

I've been working on an Android program for a bit and I'm going crazy here... I'm trying to let the user enter a few numbers that would be put into the middle of a URL. I need the code to read from a text box.

Here's what I've got so far:

public void browser(View view) 
{
    Intent browserIntent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://www.website.com/(',R.id.isbn'));
    startActivity(browserIntent);
}

Doing this just adds the (',R.id.isbn')); to the URL.

How do I fix this?

Thanks!

Answer 1

Try it in this way.

EditText t= (EditText)findViewById(R.id.isbn);  
String st= t.getText().toString();
Uri.parse("http://www.website.com/"+st); 

Answer 2

Supposing that you are talking about Android EditText field, you could read it's value using editText.getText().toString() . This is an example on how to use it in your application:

@Override
public void onCreate(Bundle savedInstanceState) {
    //... init code cutted

    Button button = (Button)findViewById(R.id.button);
    EditText editText   = (EditText)findViewById(R.id.isbn);

    button.setOnClickListener(
        new View.OnClickListener()
        {
            public void onClick(View view)
            {
                String isbnText = editText.getText().toString());
                // other code to open the new activity
            }
    });
}

Answer 3

Let your URL be like String url ="http://www.website.com/%1s/somevalue/%2s/etc+%3s";

Call String.format(url,1,2,3);

Hope this will solve your problem

Answer 4

The answer Anand posted is a simple solution to your problem. If you want the ISBN to be in the middle of the URL, you can just concatenate it like this:

EditText t = (EditText) findViewById(R.id.isbn);  
String isbn = t.getText().toString();
Intent browserIntent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://www.website.com/" + isbn + "/more-text-here"));
startActivity(browserIntent);
