Question

I have an abstract class which contains method for setting header text. It looks like:

TextView header = (TextView) findViewById(R.id.hTitle);
header.setText(getString(this.getHeaderStringID()));

At this moment methods that override the abstract getHeaderStringID() return integers like 0x7f040001.
1 I wonder whether there’s a way to utilize concatenation or somewhat similar to achieve this:

header.setText(getString(R.string.!getHeaderStringID!));

In desired case getHeaderStringID would return string like “sAboutHeader”

2 I’m new to Java – can I get rid of creating header object. If I don’t do like that, eclipse validator says that the appropriate method isn’t found and doesn’t let me launch app.

Answer 1

If I understand you correctly, I think that you should use reflection:

try {
        Field idField = R.String.class.getDeclaredField(getHeaderStringID());
        int value = idField.getInt(idField);
    } catch (Exception e) {
        e.printStackTrace();
        return -1;
    } 

the value variable could be given as an input to the getString() function.
